Turn on Wi-Fi periodically to do a quick network discovery Regarding the answer to my previous question of Android's idle Wi-Fi use, it seems like a huge waste of battery life to have Wi-Fi constantly scanning and draining battery. So it seems it would be better to turn Wi-Fi off.

However, I'd still want my Android to connect automatically to my home network, for podcast sync and other large transfers. This wouldn't need to be immediate, since I usually spend a long time at home.

I do know there are apps that give me a Wi-Fi toggle widget, but I don't want to be constantly switching Wi-Fi on and off manually. I know it's only a minor bother, but it just seems silly to have to do that since it would be pretty easy to have logic that does it for me.

Question: Is there any way to periodically (say, once every 15 mins) turn Wi-Fi on just to do a quick network discovery, then in case a known Wi-Fi is found keep it on as long as I am in range? (3rd-party apps are also okay)

(I expect this would in any case require rooting the system, but that's understandable and not a problem.)

One solution to this problem: use a tasking program such as Locale or Tasker and create certain conditions that will enable your wifi (essentially writing a script as you described).

For example:  Use GPS and determine if I'm at my home (I believe you can use real GPS, which will consume quite a bit of power, or base it off of which cell tower you are connected to, which you would already know anyways if not in airplane mode).

Or you could even setup certain times of the day you know you will be at home, or work, or wherever you regularly have wifi.


Connect PC to laptop with android Is it possible to connect PC to laptop with Android phone to share files between PC and laptop? I don't have a LAN cable, all I have is:

A PC without WiFi adapter.
An Android USB cable.
An Android phone.
A laptop with built-in WiFi.
Both PC and laptop have Windows 7.

What I'm trying to do is:
1. Connect Android to PC with USB tethering.
2. Then connect Android to laptop with WiFi tethering.
3. Then I want to share files between PC and laptop.

I don't know much about networking stuff.
Please tell me if you know.

It's possible if you are using Cyanogenmod even without any 3rd party software:

Connect the phone to the PC and enable USB tethering. Then create a hotspot on your laptop and connect your phone to it.

After that, your phone shares it's WiFi connection to your PC, so you can transfer files and use internet.

If you're not a CM user then try using PdaNet+

Flashing .tar factory image with CWM In the hopes of getting Android 5.0 onto my Nexus 10, I visited Google's factory image download page for the latest image. I noticed however that the file I downloaded was a tar and not a zip. Will this work just the same using CWM to flash it, or do I need to do something special here?

Stock factory images are not supposed to be flashed in recovery. Instead, you should follow the instructions on the page you linked to. Open the tar file, it's probably just a compressed file, just like a zip.

But first, let me point you to some custom ROMs that ARE flashable in recovery:

Stock

Rastakat

Cyanogenmod 12 (unofficial)

However, those may all contain extra bugs, as they are made by 3rd party devs.

Now, if you want to install the actual factory images from Google:

First, make sure you have fastboot and adb. If you don't, install the Android SDK.

Extract the files to a folder on your computer, connect your device to a computer and type the commands into a command window (Start -> Command Prompt or type in

cmd

The commands that you need are the one in green text, but for the sake of completeness:

adb reboot bootloader

If you haven't unlocked the bootloader yet:

fastboot oem unlock

The run the flash-all.bat script:

flash-all.bat

It should look something like this:


How to go to a specific time of a video clip quickly in YouTube app? Since the YouTube app has nowhere to input the URL, I cannot jump to a specific time to view it.
Dragging the player caret is very hard to make an accurate jump especially for a long clip
How to do that easily?

If you type/paste the URL with the time behind #t= into your browser on Android (I use Chrome, but others would presumably work the same way) you should get a popup asking you if you want to open the link in YouTube. This will open the video in the YouTube app and jump straight to the time defined.

Matt Cutts explains how to do this with the YouTube URL on his blog. Try copy/pasting http://www.youtube.com/watch?v=PjDw3azfZWI#t=31m08s into your browser as an example.


How do I choose a wired headset whose buttons work? I'm switching from iPhone to the Nexus 4 (yay!) and I know that the Nexus 4 doesn't come with a headset. I also know that for simple audio playback, any stereo headset can be used -- but I also want to use the headset to:

adjust volume with in-cable +/- buttons,
start/stop music playback with in-cable middle button,
start/end calls with in-cable middle button,
telephony with in-cable microphone.

The Apple headsets provide these abilities on iPhone so I'm assuming that something similar would work on Android as well (and specifically on the Nexus 4).

I've tried connecting the Apple wired headset to a borrowed Nexus 4, but the in-cable buttons didn't work. I'm not really surprised because I assume that the buttons send coded signals that are proprietary.

How can I select a wired headset that is compatible with the Nexus 4?
I can't very well buy one and test it, buy another if it doesn't work right, and continue until I succeed.
Surely, there is a solution here that I have been too Apple-brainwashed to see?

Alternatively, if this isn't possible on a stock Android: Is there an add-on package to Android that catches the signals from an iPhone headset and sends appropriate commands to the system?

I use an Android specified Headset with 3-button for my Nexus. Works brilliant.

Not only does it deliver 3-button action, but also very good sound and a really hard hitting bass. Anyone enjoying Rock or Electronica will not stop listening ;-)

The headset is specifically made for Android's lower voltage spec from Google and will NOT work on an iphone (the way I like it).

3-button Android spec headset with flat cable
Sabotage Royale from Degauss Labs

Webpage: http://www.degausslabs.com

Edit: 3-button headsets.
I hope anyone reading this debate understands there are Android hardware spec headsets and iPhone hardware spec headsets. They dont change in hardware or technical specifications just because you start using some software app.. (Just make them more programmable).

So if you are an Android user you should use a 3-button Android spec headset. A 3-button iPhone headset will not work 100% (up down buttons etc) and most likely the mic dont do the proper job making whom you speak to hear you bad or "from far away" or "talking in a coke-can". There are 100 times more iPhone spec headset out there, dont ask me why.


Unable to play Snapchat videos I have a Samsung Galaxy Ace and I am unable to view most videos on Snapchat that people send to me. I have tried to rectify the problem by downloading MX player and VLC player and updating to Snapchat beta. However I am still unable to view almost all Snapchat videos and was wondering how I fix this problem?

You can try to resolve your issue by below ideas.

Your device may not support the quality in which user has recorded that video.
You need to clear cache memory of phone, or reboot your phone.
Size of video is so large, it will be unable to view that in your net speed(2G).
You should try deleting the app and re-downloading.


Nexus 5x - No one can hear me on the phone I've had this phone since November and it's still in great condition. From the start though call quality hasn't been amazing, friends often tell me that I'm very quite (I'm not actually speaking quietly). In the last few days though absolutely no one can hear me unless I have my headphones plugged in but even then it's not ALL the time that it works. The headphones don't have a mic so it's nothing to do with them I imagine. I've made a few videos to check that it was still recording sound and it works perfectly still. It's really left me baffled. While the phone is still in warranty I really do want to avoid sending it to LG as I don't have a backup phone.

Does anyone have any idea what could be causing this? I'm running stock vanilla 6.0.1  I don't have a case on the phone (I've seen a few people complain their case covers up their mic), neither I've muted the call (I've tapped the mute button a few times to make sure).

I had this same issue with my HTC One. It turned out that the background noise cancellation software build into the phone canceled out too much (thus cancelling out my voice). This especially happened when it was windy outside.

That being said, I haven't heard of this being an issue with the Nexus 5x. I would start with contacting Google support.


Block regular and whatsapp outgoing calls I want to disable a certain number, not to make regular and WhatsApp outgoing calls  on my sons phone. Is there a way, I can do this , without him knowing about it?

EDIT: It is impossible to do this without your son knowing, as acejavelin said. This answer is the second best thing.

If I think what I think you are saying you, want to block out going calls on your phone? Here's a way to do it:

To block a contact that is saved in your phone

Open WhatsApp.Tap the Menu Button > Settings > Account > Privacy > Blocked contacts.Tap the add contact icon.Select the contact you wish to block from the list.

To block a number that is not saved in your phone

Open the chat with the unknown contact. Tap Block.

When you receive an initial message from an unknown number, you will also have the option to Report spam, which will report and block the user.

To block calls on your phone:
It varies phone by phone, but here is instruction for some commons OS versions:

For Marshmallow or Nougat, open Dialer, go to your recent calls list, find the number you want to block and select Block/Report Spam. (If you don't want to report the number as spam, you can uncheck the box.) Then tap Block.

For Lollipop, go to the Phone app and select Call Settings > Call Rejection (ouch) > Auto Reject List. Type in the number or search for it, select it, and you're done.

How can I recover my pictures from Vaulty Stocks I've lost my phone. Is there any way of getting back my files and pictures which were saved in Vaulty Stocks?

I realize that this doesn't directly answer your question since it appears you don't have a backup, however I have used Vaulty, which looks like the free version of the same app by the same company, so I am assuming the method used to hide your files is the same.

If you are able to find your .vdata files you can easily convert them all back into regular files by the command line without any sort of password/pin.

Make a backup (just in case) and then put all your .vdata files in the same directory and execute:

find . -type f -name "*.vdata" -print0 | xargs -0 sed -i 's/\x6F\x62\x73\x63\x75\x72\x65\x64//

Poof. There are all your files. This definitely works for Linux, but I'm not sure about Mac. If someone can confirm this for Mac feel free to update this answer or comment and I'll do it myself.

Unfortunately (if you are actually interested in security) Vaulty DOES NOT secure your files at all! If you need real security, you need an app that actually encrypts your files with something like AES encryption. However if you lose your password there, you're sweet out of luck. That's a good thing. Just make sure you don't forget your password.


How to flash cyanogenmod to my HUAWEI P6 t00 I have a Chinese phone, Huawei p6-t00. I don't like the stock rom on the phone that much and i want to switch to cyanogenmod. The problem is there is only a version of cyanogenmod for Huawei p6-u06 on the Internet. And when i tried to flash that to my phone, it gave me some kind of error like this rom only supports Huawei p6-u06. So i am wondering is there any way that i can flash cyanogenmod to my phone without damaging it? Thanks in advance.

Due to the device-specific nature of Android (it needs specific drivers for it to run on any one given device), it is generally impossible (or illogical, as it seems) to run a build of Android for a specific device on another device.

This also applies to custom ROMs. Unless you can find a CyanogenMod build specifically for your device or for an extremely similar device, there's no way for you to install CM.


Copy Album Art from One Song to Rest of Album I'm uploading music and Google auto-detects some of the artwork, but not all of it. Is there a way to copy the detected artwork to all of the songs in the album?

Easy!
1. Select album with missing or incorrect cover art
2. Goto iTunes or other music app that contains that album with your desired cover, select or right click edit, select cover and drag to your desktop (or copy and paste on desktop)
3. Go back to google album with missing cover, right click and select edit, in the edit screen select the up arrow in the cover section and select the cover you placed on desktop, then save edit screen and voila: the cover is where it belongs, hurray!
4. This way associates all tracks with the same cover, easy!
Cheers


My device is grayed out on Google Play website Recently I had some trouble with google play app - first, I was getting "connection error" when using wifi. I cleared the app chache, uninstalled updates and after I played with it a bit more, it completely stopped woking giving me the "connection error" also on 3G.

I erased my device and installed CyanogenMod 10.1.

Now the Google Play app woks great but when I go to Google Play website, my device seems to be out of sync - it is grayed out and the list of apps installed is out of date.

How to fix this? Any ideas?

Try installing Titanium Backup and use its "Manage Android ID" function to update your device ID and "Market Doctor" to relink apps to the market


How can I find out the make and model of the chips in my device? I'm trying to find out what kind of GPS receiver is in my phone. Every spec sheet is vague on this. I can easily find out what kind Soc or CPU it has, but parts like GPS and FM receivers, Bluetooth modules, Gyroscope etc. are not listed anywhere.

Is there any way to find it out?

For the best resource out there, use PDADB.

This details every comprehensive chip-set used, for the Droid Charge, this is the spec sheet given.

As for Huawei U8160, this is the spec sheet given on that page.

Depending on how open the manufacturer is with the more intimate details, some may be marked proprietary which will be stated clearly.

The other way of doing it, in the case of the Droid Charge which is a Samsung model, might be to hit up on the Samsung's open source site, and look for the appropriate kernel version for that handset and examine the kernel configuration as appropriate.

Google Services Framework keeps stopping I installed LineageOS on my S7 Edge and after I started it, it keeps saying "com.android.phone has stopped" after I removed my SIM-Card it said "Google Services Framework keeps stopping" and it goes in a bootloop after 2-3 min. with no input.

try wiping dalvik cache, re-flashing the rom and the GPApps. that is how i have fixed this issue in the past on my nexus 6. if that dose not fix it wipe all data and cache in twrp then re-flash rom and GPApps


Is it possible to install Kali Nethunter's Apps on OxygenOS? I just bought a OnePlus 3T. I like the OxygenOS, but I wish I had the ability to preform USB HID Attacks and use apt-get on OxygenOS if I don't want to install Nethunter. Is this possible?

Try Termux, a free application which allows you to access apt-get and many other Unix commands right on your smartphone.

You can also install the termux-sudo plugin, which allows you to run commands with root access.


Android File Transfer not working between El Capitan and Android 6 I have a Nexus 7 and a MacBook Pro running El Capitan (10.11.6).  I just installed Android File Transfer (1.0.11) and connected my Nexus.
Result: Android File Transfer automatically opens, but says:

Can't access device storage.
Make sure your device is unlocked and "File Transfer" or "MTP" mode is selected.

I found Google's troubleshooting page, and updated Android as per the advice there.  I'm now running Android 6.0.1 with security patch level August, 2016.  I got the same result.
My device was unlocked and there was no notification on the device when I connected it.
I found https://android.stackexchange.com/a/125679/190389 and followed those steps, but found that MTP mode was already selected, so that wasn't the issue.
I tried with more than one USB cable; one dinky cable resulted in the computer not recognizing that the device was connected at all (i.e. the device charged but Android File Transfer didn't open automatically, and when opened manually it said no Android device connected).  But the cable resulting in the error message above was a sturdy good one that I got from WASD Keyboards along with my high-end keyboard purchase.
How can I get Android File Transfer working?

After struggling a lot and checking many solutions off the internet, my issue turned out to be related to "turning off and on again" the SIP (System Integrity Protection) on my Mac. I did the following and it magically works again:

csrutil disable (and then reboot) → ADB/Android File Transfer not working yet.
csrutil enable (and then reboot) → ADB/Android File Transfer already working up to this point.
csrutil enable --without debug → I've gotta do this because I'm using XtraFinder and want to make it work for El Capitan.

See if this resolves yours :)


What happens if I remove my dropbox account from my phone so I can add another account? I want to add another account but I have to remove the other one first. Will that delete all my photos? Or can I still access my photos if I log in on my dropbox account online?

Logging out will not delete your photos or other content. You will still be able to access all content in the old account via re-logging in on that device, another device, or in browser.

However if you have multiple accounts, you may want to be sure that you are using each account in accordance with the terms and conditions of service of Dropbox.


Can apps update without Google account? Scenario:
- No Google account is attached to the phone
- No apps have been installed beside ones that where already on the phone (even after a factory reset)

Questions:
- Is it possible to let the apps update without entering any Google account?
- Can apps update in the background when no Google Account has been entered into the phone?

I could not find this information in the FAQ.

No Google Account means no Play store.

And one thing is clear, if you don't sign in with Google account then it will not allow you to download or update any application from/to play store.


Play store error #963 I have a Xiaomi redmi note 4, last week, I flash super su with TWRP, I change the sd mount to EXT4 because I have a problem, but is solved, and I wipe data. When I reboot the phone to system, all is OK, but I can't install any apk from play store, I get the error 903. I try to wipe data, wipe play store cache, uninstall the updates, reinstall play store, wipe data of google play services, etc... But nothing works. Right now im using Aptoide, please help, thanks you.

When using the methods reported by @Izzy, none of them solved the issue on my Galaxy On7, rooted to work with Android Pie (9), LineageOS 16 flavour -- using an SD Card as adopted storage.

Here is what I did:

After enabling Developer Options, I checked the option "Force Allow apps on external"
Cleared the play store data;
Rebooted the device

Now all apps on playstore, which I had forcibly moved to the sd card with Titanium Backup, are able to be updated with no issues.

Hope this helps


Photos and music from internal storage got deleted. How to recover them? I restarted my LG Android phone and it was supposed to back up my phone's memory – but it deleted my photos and music that was saved to my phone's internal memory.

How do I get my music and photos back?

I will guide you with the process of getting your pictures back. (For music I would say you always download them again from their original source). Additionally to your device, this procedure will require a Windows or Mac computer/Laptop and an USB cable.

I am going to guide you over here with the help of Dr. Fone for Android by Wondershare. So download and install it over your PC/Laptop.
Connect your device with your PC/Laptop with the help of USB cable. Also make sure that USB debugging is enabled over your device. If the USB debugging isn’t available then you can always enable USB debugging under Developers option available under setting. You'll see a notification at the bottom of the screen saying that USB Debugging is being opened in the Dr. Fone Software over your PC/Laptop.
Once the connection has been made you will be able to select categories of deleted files i.e Photos, Contacts… etc ! Tap over the category you want to recover! Next Step is to tap over the Scan button for deleted files and follow the options appearing on the screen!

  Note: You'll need to accept the RSA key prompt on your smartphone (check ''Always accept'' to make it easier), making the connection between the two devices secure.
  Once it will analyze your phone. There will be reboots, don’t be panic and let the tools do what its doing. Now you’ll get the scan results where you can tap over the check box for the photos you want to recover, so click over it and hit the recover button. And you will get your pictures back!

  Hope this time my post helps you in getting your photos back!

Btw: Behind the above link, you can also find a screencast visualizing the process I've explained here.


twrp failed to sideload I tried flashing a custom rom using ADB Sideload in TWRP 3.3.0.0. Now I am unsure how to proceed. I did my preparations:

Bootloader is unlocked
USB debugging is enabled

However when the sideload froze, after 20-30min I unplugged usb. When I inserted the usb-cable again I tried the following things:

when I type adb devices I see my device-id and the status is recovery
fastboot devices is not returning my device
adb push returns me a couldn't read from device
ADB Sideload in TWRP wont work
when I trype adb rootI get a msg saying that I already am root

Now I am wondering what to do. When I go into twrp reboot menu I have the options System, Power Off, Recovery and Bootloader. In addition I have the option slot A and slot B. It also tells me that currently I am in Slot B. Here are my questions:

How do I reboot TWRP from TWRP? My current guess is to reboot Slot B

I also noticed in previous installations that TWRP seems to reboot automatically if no System has been installed.

What is the difference between rebooting Slot B and Recovery? Would both reboot in TWRP?
Does it make sense to reboot into Bootloader?

Do I then need to flash TWRP from fastboot again? Because I am unsure if this would work, as currently my fastboot doesn't find my device

Update:
I am using a temporary TWRP booted using fastboot flash boot <twrp-image.img>

Not sure this counts as an answer. But I prefer to summarise what I learnt from the long comment thread. Note these are lessons learnt from flashing 4 Android Phones in the last 3 months:

Check your usb-cable before starting. If it doesn't connect to the laptop where your adb is installed, get a new one!
If you install want to unofficial builds, try to have at least another alternative ready for installation. Best try to have at least one alternative stable build ready for installation.
Unofficial builds may not support ADB as @alecxs pointed out in the comments
Have an OTG cable ready! I didnt have one ready, but ordered one and left the phone in TWRP for the days until it arrived. With the OTG I managed to install without issues

If 1-4 do not work for you, then I suggest rebooting into bootloader. Thanks @Evan Carroll for the link: Is it possible to boot into a different recovery from TWRP?


Need to upgrade from Android ver. 4.4.4 to Android ver. 5.0 with unlocked bootloader I have an Xperia Z and recently I unlocked the bootloader. However now I cannot install (upgrade) to the Lollipop Android 5.0 (10.6.A.0.454) from Android 4 (10.5.1.A.0.292) through the Sony website. I always get the message "cannot be installed because I have an unlocked bootloader".

Please advise on a step by step process to lock the bootloader again if possible or advise on how to upgrade to 5 version.

Please make it for dummies because I am not experienced or a developer whatsoever.

Actually it's possible to relock the bootloader, using Flashtool. The process can be found on this XDA Forum post.

Download Flashtool from www.flashtool.net
Start Flashtool and click on BLU button
You will be asked to connect device in flash mode
Once you connect the device you will get a prompt to "Relock"
Click on it and when prompted disconnect the device


Nexus 7 won't show up as a drive on Windows in MTP mode after update to Android 4.2 It used to work just fine then I upated to 4.2 and enabled developer options (one or the other must have broken it) and since then it has stopped working, it shows up as a camera device but if I change it to MTP it doesn't work.

I tried turning developer options off, I tried re-installing drivers and a few other things.

How do I make it work again like it was in 4.1 when it worked even when usb debugging was enabled? Now it won't work at all.

What worked for me (on Windows) was:

Plug the Nexus 7 into your computer with the USB cable.
Open Device Manager: Start -> Run (or Win+R), type in: devmgmt.msc and hit enter. This opens up the device manager.
Find "Android Composite ADB Device" near the top and expand the node. Double click on the device. (Note: Sorry, I don't see it anymore so it might be named slightly differently.)
In the properties window that pops up, uninstall the driver. You should choose to delete the current driver as well.
Unplug the tablet and plug it back in.

At this point mine got recognized as a Nexus 7 instead of an Android ADB device and allowed me to transfer files again.

I'm not sure how this will affect debugging (especially if you delete the old driver) but it worked for me after days of searching.


Possible to use another application as default camera application? Many apps let u use only the default built-in camera app. They not allow you to choose a third party app, such as the app "fake camera". Is there a way to remove/replace the default camera app? Any ideas?

Yes, it's possible. At least, on some devices. But without knowing anything about your device, it's hard to answer your question.

For example, on Android 8, you have a menu like this: If you have a search option in your settings, then you can easily search for "default", and you will find it easily.


The easiest way to root a Moto G (XT1032) Android v. 5.0.2 I have just rooted a samsung Lite 3 tablet...and it was simple. Really simple. Used Odin to install CWM, then installed a superuser app from a zip file. Really straightforward.

So I decided to look into how to root and get super user access to my Moto G. That's when I realized that rooting a moto G and getting super user access will be a pain.

Does anyone have a straightforward description with the apps/zips necessary to root and gain super user access to a moto G XT1032?

Cheers

Steps :

Install custom recovery TWRP(Download link)

Install SuperSU from recovery

I’m new to SetCPU on Moto Droid and need help I'm running rooted stock Android 2.2 on a Motorola Droid. I was hoping other users of the app could give me some advice.

First question: whats the best underclock setting for a good balance between performance and longer battery life? How much longer battery life is it giving you on average?

Second question: I told it to autodetect the phone and I can seem to only overclock to 800mhz. How do I overclock to 1ghz. How high can I/should I overclock? I'm only overclocking when I play psx4droid.

Third question: any recommended profiles to setup?

Thanks!

That's going to depend on how much you're using it during the day, I would say start at 700 and move it around until it feels smooth for you.

I wouldn't push the phone that high, first it's going to overheat pretty quickly, which can permanently brick your phone.  Even 800 is going to be rough on it so I wouldn't leave it up that high for very long.

I've got an eris (Did a little looking around, and the Droid CPU is set at 550Mhz whereas the Eris is set at 528Mhz as reference points) so this is going to be a little different than what you've got, but here's my profiles so you can tweak as needed.

Temp > 36.9 C 528Mhz/160Mhz Priority: 100 (This is the failsafe setting, if the phone get's too hot it'll cut the CPU speed so the phone can cool down and prevent any damage)
Charging/Full 729Mhz/528Mhz Priority: 80 (If the phone is plugged in, it can run a little harder, but I also don't use my phone much when it's plugged in)
Battery < 100% 710Mhz/528Mhz Priority: 50 (This is the normal use setting, which keeps the phone moving smoothly, but doesn't get too hot)

The most important thing is that you have scaling set to ondemand.  This will turn the processor down if it's not being used.  Hence, on the last setting, it is very rarely at 710Mhz and is most often below 550Mhz.
Second to remember is not to set the minimum too low, or the phone will have trouble waking up from sleep. You'll need to do a little digging around to find out what the ideal min is for the droid, but I would suspect above 160 Mhz would be safe for you.
Those should cover most bases, at bare minimum add the failsafe profile so that you don't lose your phone.


How to enable preview in notifications on an Oppo phone I recently started using an Oppo A77 phone and have no experience with ColorOs.

I think I found the answer. I was also looking for the answer because I also wanted to expand my notifications and I tried it and it works.


How do I find the kernel config for my ROM? I'm very happy with CM11 ported to my phone(Samsung Galaxy Ace 2). One day I bought Bluetooth keyboard.

When I tried to connect it, it paired and... wat? No connection!? I thought that this ROM has some bug, so i looked at logcat. I found that there's no uhid driver and I think that developers didn't compile kernel with "CONFIG_UHID=y".

I'm gonna compile new kernel.

First I need to check it, but there's no /proc/config.gz. How can I check(and compile) that without it?

ROM homepage: http://novafusion.pl/

EDIT: Seems like that other CM/AKOP ROM's for my device don't have uhid support(or kernel source is crap?). Keyboard works fine with Stock ROM

If the kernel wasn't compiled with /proc/config.gz support turned on, then the only sure way is to look at the source tree that was used to compile the kernel you're running. Copy the config.h file into your own source tree (or just use the original source tree) and run make menuconfig to set any new options you want.


How to preserve battery while trekking remote locations? I will use my phone while trekking in a remote area and want to conserve its battery. I won't have phone or wifi networks, but I want to record my track using Google's My Tracks and take photos.

How should I configure my phone to maximize the battery duration?

I'd like to know the specific things I should change for using the phone as a GPS recorder and camera, so it is different of this question. I know that I can turn off wifi and the Sim chips. Maybe I should use another GPS tracker.

I have a lot of apps installed, and nowadays it looks like even a ridiculous weather app needs to start a service. Should I uninstall them?

I'm using a Moto G first generation and Android 5.0.2.

MyTracks is a fairly power hungry app, because it does lots of things as well as recording a track. eg it shows maps, and graphs, and gives voice announcements etc. For just recording a track, a simpler app would be better.

I recommend GPS Logger for Android, which aims to be more battery effecient. It has lots of settings which can save battery power. Specifically, the time interval before recording a point - you can set this to 60 seconds or more. Also turn off the option for "keep GPS on between fixes". This should still record a fairly detailed track for typical walking speeds, though it may miss some of the tight corners or twisty paths.

For other power saving, yes it is worth turning off wifi and mobile data. You can also complete disable the mobile phone connection, ie set it to airplane mode. This help a lot if you are in an area with poor coverage, because otherwise the phone will waste power trying to find a signal. Obviously this means you can't receive any phone calls/texts, but recording a GPS track will work fine.

Also any other apps running in the background may be wasting power. You don't have to uninstall them, just disable the apps to stop them running. If you go to Settings > Battery, it will tell you what apps are using most power.


Disable vibration in Samsung? (Attention: Samsung's 9.0-Pie / One UI is different from stock Android)

Is there any way to completely disable vibration in a Samsung phone running their flavor of Android Pie (9.0)?

I already have Settings / Sound and vibration / Vibrate while ringing tuned OFF, but the phone still vibrates for various notifications.

The problem is that vibration makes this phone slide off whatever hard surface it's on.

Go to Settings -> Accessibility -> Vibration and switch it off


My device is getting slow, apps start misbehaving/crashing. What can I do? Everything was working fine for a long time. But suddenly the device is getting slower than usual (e.g. apps react slowly when starting an action -- like the RSS reader takes "ages" to open an article). Also, several apps start crashing: force-closes as well as unexpected restarts. Sometimes this even involves some automatic reboot of the device.

Is there anything I can do, besides doing a factory-reset? Preferably it should work on un-rooted devices.

Remark: not all described problems may occur together, so on one device e.g. there might be no automatic reboot involved. Question remains the same, nonetheless.

A behavour as described above in most cases indicates something's messed up in the system. The most likely candidates here are:

Application Cache
Dalvik Cache

As you might have guessed already, different solutions are available for rooted devices -- but only few for non-rooted devices, which cannot directly access the Dalvik Cache. So read on below examples until you hit something working for you, or continue to the very end for all options.

rooted and non-rooted devices: remove obsolete apps

Cause of a slow-down might be some app, hogging all resources. Those apps usually can be identified via the "battery consumption" page in Settings. But even if you cannot find it there, it cannot hurt to remove apps you once installed but no longer need (see e.g. Alix' answer).

You can also disable some system apps you don't need (keyword: bloatware). To do so, go to Settings → Applications, select the "All" tab, and walk the list to find those apps. Tap their entry, and you should find a "disable" button. It might be grayed out: if so, you first have to "force stop" the app, and maybe to "uninstall updates", before the "disable" button becomes accessible. Note however, that this possibility will not exist for all system apps. For rooted devices, there are several tools available allowing you to "freeze" or even remove system apps (be very careful with the latter); one famous example is Titanium Backup.

rooted and non-rooted devices: Clear the Application Cache

If you're lucky, it's simply that: the Application Cache got filled/messed up. This can be easily resolved, even on non-rooted devices:

With methods available by default on each Android system:

From your homescreen, go to Settings → Apps → Manage Apps. Make sure to view All Apps, not Downloaded only
Walk the list, open each app, and hit the Clear Cache button

Easier method using helper apps: There are several apps available on the Playstore which allow to clean all application's caches at once, so you don't have to walk a long list and do it manually. One example for such an app is 1Tap Cleaner, which also can clean up several other histories like e.g. the browser history

rooted devices: Clear Application Cache and Dalvik Cache

Even more likely for the described case is a messed-up Dalvik Cache -- especially if you tested a lot of apps, permanently installing/uninstalling different ones. So a cleanup of the Dalvik Cache most certainly will solve the situation. As a side effect, it will certainly speed-up things. No negative side-effects are to be expected.

Via Custom Recovery
This is the most effective way and sure to really do the job. This example is based on the ClockworkMod Recovery, which is most widely spread. It should be equivalent with AmonRa Recovery.

Boot into recovery mode (how to do this often depends on the device/ROM used. For CyanogenMod users it's most easy: Long-Press the power button, select "Reboot", select "Recovery")
Using the Volume controls, select Wipe Cache and approve it using the power button. On the next screen, approve the action the same way. This way you easily clear the Application Cache as described above, all at once, without the need of an extra app.
Go to the Advanced menu, select to Clear Dalvik Cache the same way with the Volume and Power keys and approve it.
Go back to the main menu, and select Reboot. The next reboot will take longer as usual, so don't worry: Android needs to rebuild the Dalvik Cache, that's completely normal behaviour.

Helper apps:
Several apps offer options to cleanup the Dalvik Cache (e.g. SystemCleanup and Titanium Backup PRO Key ★ root). You can try those; but I'm not sure if one of them really "wipes" the Dalvik Cache. At least for Titanium Backup I know it only removes remains from uninstalled apps (i.e. obsolete Dalvik files).

rooted and non-rooted devices last resort: Factory Reset

If none of the above does solve your problem, there's always the Factory Reset. Basically, this does all the above (wiping Application Cache and Dalvik Cache) -- but it also wipes the /data partition. This means: All your settings and data (except those stored on your sd card) as well as all apps you installed yourself are gone. So be sure to have a good backup before doing this (see e.g. Full Backup of non-rooted devices for how to achieve this).

rooted devices: fstrim

Another reason for slowing things down lies in the storage. A little background for understanding:

On the flash memory used in our devices, each cell can only be written so many times. To prevent capacity loss and wear-out, the flash controller applies an algorithm called "wear leveling" to evenly spread writes across the medium. Of course, to prevent data loss you want to write to "empty places" only (except when explicitly overwriting a file). And here comes the culprit: To speed things up, the file system in most cases only marks files deleted, but doesn't tell the controller about the "freed blocks" -- so it becomes inefficient with time.

Android 4.3 addresses this issue with appropriate fstrim calls, telling the controller once a day which blocks to consider freed. Some ROMs integrated a comparable feature also in earlier versions of Android, mounting file systems with the discard option (so the controller is informed at once on deletes), but this slows down deletes a little. For devices not having addressed this in either of the two ways, it might be worth to take a look at the Lagfix App, which calls fstrim in a user-friendly way for selected partitions. Running that once on a long-used device may speed up writes by a factor of up to 30, and even reads get a little faster.

TWRP backups will restore but not boot, only bootloop Synopsis of Issue:
Currently I have several backups that do not show an error resoring but for some reason will not boot. Everytime I boot the device from a backup it goes into the WIleyfox boot screen and stays like that.

Background Information:
I own a Wileyfox Swift 2x, unrooted and bootloader unlocked. TWRP 3.1.1 is installed. I upgraded the system to Nougat 7.1 [SW46-WF-MARMITE-7.1-TOS089A-RECOVERY[NOUGAT] and everything seemed to function properly albeit with those annoying corruption startup screens. However for some reason I just coudnt get it to ROOT. I took a full backup. So I decided to install Lineage 14.1 [lineage-14.1-20171002-nightly-crackling-signed] with open-gapps. After a wipe I installed Lineage but it woudnt boot despite fixing error7 issue. ...I moved on>>>

I next tried to install Cynogenmod 13.1 [SW33-WF-MARMITE-CM-13.1.5-ZNH2KAS7EB-RECOVERY] with open-gapps and succeeded but later realised there was an issue with ROOTing and phonecall recorder - anyway I needed a working phone so attempted to restore Nougat 7.1 (above) after backing up Cynogenmod 13.1.

This is when i realised that none of my backups would restore. The phone will not boot and all I am left with is the Wileyfox boot screen. I tried restoring with and without system image, & only restoring with boot, system & data - I have performed all of these after performing the standard wipes but it remains the same.

Help:
Can anyone help me get my phone into working order so that I can restore my backups and boot into them?

I'm not sure how you installed LineageOS and others, but maybe downloading a stock Wileyfox image and following the steps below would work?

WARNING: I did not try it!!

Image found here: https://forum.xda-developers.com/swift-2/how-to/marmite-android-7-1-1-tos118c-fastboot-t3605101 (probably use the fastboot one)

Steps to revert to stock state (copied from here: https://forum.xda-developers.com/wileyfox-swift/general/7-1-1-swift-update-t3592328/page6 ):

fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn

fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash splash splash.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery revovery.img

Also, you seem to have installed the lineage-14.1-20171002-nightly-crackling image intended for an old swift (crackling), on the newer swift 2x (marmite). That's probably why it didn't boot, right?


Google Play not responding after CM13 install Today I installed Cyanogenmod CM13 and Gapps on my Asus Zenfone 2. The install went fine, but when I booted my phone, I selected the language, then when it went to look for updates, a system message appeared "Google Play services has stopped". This has caused the phone to hang at the update page, and to top it off I forgot to install TWRP, so I think I'm going to have an issue installing a fresh install.

What can I do now?

What happened
You don't have TWRP, so your phone is bricked.1

How can I unbrick it?
Look at this website.

The website tells you

How to install ADB (which you can also find here on Android.SE: Is there a minimal installation of ADB?, takes less space)
And unbrick the phone from there. It also gives u the full ROM.

The latter in short requires you to:

Download and install the drivers for your Zenphone on your Windows PC2
Get the latest ROM for it (e.g. Zenfone ZE551ML Stock ROM (4GB version) or Zenfone ZE550ML Stock ROM (2GB version))
use recovery-mode to install that ROM (via "Apply update from ADB", so you can use adb sideload file.zip to apply it)

1: for installing TWRP, see e.g. How to Install TWRP Recovery on Zenfone 2 and Root at Androiding.how. Before that, install the stock ROM and wipe cache+data (from recovery; a factory-reset should do the wipe as well).
2: not needed on Linux/Mac; for those OSes, see e.g. Configuring ADB on Ubuntu


Podcast Player and Bluetooth? I've been using Google Listen for podcast catching and playing. Seems to work just fine. I'd like to be able to play my podcasts over my Bluetooth headset. Alas, it seems that is only an option for A2DP bluetooth headsets(?) so I'm on a quest.

Can anyone offer suggestions? Seems like I have two options (but maybe there are others).

Find a podcast catcher/player that will play over a non-A2DP headset
Find a way to "fake" the Android into using a bluetooth headset even when not A2DP

Anyone have any thoughts or suggestions?

[edit]
I should mention that I'm running stock 2.1 and have no real desire to root/mod the phone.

Try Super BT Mono.  It doesn't explicity say that it works for non-AD2P headsets but I believe that's the whole point of the app.  There'd be no need for this app with a headset that has AD2P.

Edit: Whoops, that's for Froyo only and you are on Eclair.

Basically you need to find an app that will stream audio over the HSP profile instead of AD2P but I couldn't find one for you.  You have 3 options as I see them:

Get Android 2.2 on your phone and Try Super BT Mono Froyo Pro
Root your phone, load CyanogenMod and try Super BT Mono Pro
Buy a headset that supports AD2P (they can be as cheap as $30)

Sorry I couldn't help more.


Does anyone know why after I updated my android phone, that it doesn't unlock? I literally just updated my phone (I have a BLU X2 if that helps) to the new Android thing last night and my phone shuts down whenever I have any new updates. But I can't seem to unlock my phone this time. Like my password isn't working once I turn it back on and I've also tried all my old passwords and none of them work D:

BLU pushed a bad update. Just google for BLU OTA lock. Looks like a factory reset is the only solution for now.


Can I auto-rotate the screen 180°? Is there any way to make the Android 2.1 automatic screen rotation rotate all the way up to 180°, instead of just 90° either way? I would very much like to be able to use my phone upside down, because the audio jack is on top.

I've looked all over the web and the only advice I found was to install a custom rom (like Cyanogen,) but I haven't found any builds suitable for my Samsung Galaxy S.

I do not believe Android 2.1 allows this. I've read that the latest release Android 2.3 (Gingerbread) will have this feature.

Sorry I couldn't find the post that mentioned it but here is the API link.


Create new image file of 750 x 380 px on Android phone I need to create a blank 750 x 380px image on my android phone - then paste some images and text onto the blank image. Simple as this sounds - spent over 72 hours searching the Web with no way to this. Pixlr and all other mobile image editing apps can only edit existing images - but won't allow you create new ones with fixed canvas size. Suffice it to say I haven't got access to a computer now and must do this on my Samsung android mobile. Help guys - I'm about to really really freak out.

Don't freak out. That would be silly.

I just tried (for your question) an app named PhotoSuite 4 Free. I was able to start a new project, specify its pixel dimensions and add a text layer. Seems to be what you're looking for.

HTC HD2 Can't start certain App from SD with CyanogenMod Gingerbread 2.3.3 I've installed BOYPPC-SHIFTPDA DESIRE HD V7 & GINGER 2.3.3_V9 (NAND [DAF]Clean) on HTC HD2, everything is fine except I can't run some app (almost all app large than 1Mb) from SD (eg. Angry Birds from Market). I can run the app if it is installed on the phone memory, and I can install or move the app to SD, but when I click the icon, it shows "application…stopped unexpectedly". My friend running another mod with Ginger 2.3.2 don't have this problem. Is there anything I can do to make it work? Or this is the thing beyond my control?

It looks like those ROMs just don't support App2SD.  Someone else was asking about it: http://forum.xda-developers.com/showpost.php?p=12193603&postcount=453


How to edit id3-tags (MP3 tags) in Marshmallow? Ok, so I'm not got to act like I know what I'm talking about, but I've done a fair bit of googling and stuff like 'write permissions' have come up over and over again when searching id3 tag editors.

My question is, how do I edit my music titles? ie album name and song title. Some of my songs have unknown artist or album.

I have a LG G4 with marshmallow 6.0, my old G4 had lollipop and I could edit my music with an app. That phone got run over, my new G4 now has marshmallow. I bought it a few weeks ago.

The apps that claimed to work don't, black music player had a built in editor and it looked promising, it let me edit my music but after exiting the app and going back in, it had changed back to the original title.(two hours of my life I can't get back.)

So is there anyway around this with a simple fix? Nothing too technical please like 'rooting' whatever that is....or I've read you can convert your external sd card to become an extension of your internal storage somehow...and I've heard bad things about that too, like lag and storage issues.

I just want to organise my music....something I enjoy doing.

So any ideas would be great
Thanks,
Beck.

You need not rely on the apps that help you edit the MP3 tags easily.. As @Somberi said, maybe the developers could have abandoned their projects..

There's a very tedious solution anyway, by which you can edit the ID3 tags manually.

Steps:

Download any Hex Editor app for Android.
Open the mp3 file using that Hex Editor.
Scroll to the end of the file..
The last 128bytes over there is used to store the metadata (ID3 tags)
Just note the last 128bytes & try to recognize the tag-names used there by converting each byte to corresponding ASCII. For example, the hex bytes 45 6D 69 6E 65 6D corresponds to the ASCII string Eminem ;)

Just change it as required (by converting your ASCII text to Hex bytes) & overwrite it in the corresponding location. Also note that each tag-name is separated by a sequence of spaces (20 20 20 20 ...... in Hex), or in some cases, sequence of null-bytes (00 00 00 00 ......), which varies for different ID3 versions.

(This might also help: A Quick Study on MP3 file structure )

When you need to edit multiple MP3 files, this process is really exhausting..In that case, you may wait till the app developers update their apps (with proper permissions) for Marshmallow, or you can do it easily on your computer, even using VLC Media Player (Tools->Media Information)


Google Play does not install applications through OpenVPN connect Google Play works fine as application browser, but fails to install any app when OpenVPN is active. The same problem repeats on 3 phones from different vendors.

How to investigate?

To answer the "How to investigate?":

Enable ADB (Android debugging) on your phone.

Go to settings -> about this phone (or similar naming) and press the "Build number" 7 times. Congratulations, you are now a developer!
Go to settings -> Developer Options. Enable "Android debugging"

Connect your phone to a PC and install adb on there.

On debian based Linux: apt-get install adb
On arch based Linux: pacman -S adb
Please see Google "How to install adb on YOUR_OS" for other Operating Systems

Open a terminal on your PC (On Windows, make sure you are in the same directory as the adb binary. You might need to replace the adb below with ./adb or ./adb.exe on Windows.)
Run adb devices to make sure your phone shows up. Confirmation on phone might be required.
Run adb shell to get a shell into your phone.
Within that shell, run logcat *:W (without the *:W for more verbosity).

You will now get a lot of log entries, the *:W shows only warnings and "worse". Without disconnecting USB or closing the shell, try to get something from the Play Store now. Watch the log window on your PC. Try to look for anything related in there.

My guess is that Google simply blocks downloads from your VPN (logcat should show this clearly), so have this workaround aswell:

Install F-Droid

F-Droid is an alternative App Store that has a lot of really nice open source applications.

But I want an app that isn't on F-Droid

Check out Yalp Store on F-droid!

I personally do not use Google services and removed everything Google from my phone. Nor do I have a Google account. Whenever I do need an application that's only on the Play Store though, I use Yalp. You don't need an account, you can browse apps just like in the Play Store and they install just as easily. It's kinda like a proxy to the Play Store. APKs are being downloaded from Google, not some fishy weird websites, so it's safe to use.

Depending on how Yalp works exactly, it might try to access the APK from Google's servers using your IP, which means it might still get blocked. But it's most certainly worth a try and might very well work!


TI SensorTag firmware Update through OAD(over-the air ) in android Help me to upload firmware through android app in nexus 7 ,as I have build my sensor tag project through IAR embedded workbench,but I didnt find any app for OAD firmware update in android, when I am trying to update firmware through TI ble device manager android app, its telling "OAD service is not available" while it has OAD service uuid0xFFC0.

It's not available because you have an old version of the TI firmware in your SensorTag. Some months ago they added the "Connection control service" to the SensorTag firmware to enable OAD with Android. If your firmware is not recent, it has the OAD Service but not the Connection Control Service, so you'll have to use iOS to to OAD.


Old phone to track my bike in case of theft I have an old galaxy s3, I was thinking of storing it in my bike seat or a lockbox on my bike in case it gets stolen so i can track down my bike. Is there any way of doing this without a sim card(phone works without one) or a sim card without data, just minutes? I live in Canada and the cheapest simcard with a dataplan i can find is 711 speakout for$10 a month. Im looking to spend less than that, anyone have any ideas?

One possible solution would be to use avast! Anti-Theft which allows you to text 1234 LOCATE to your phone in order to locate it, replacing 1234 with your avast! PIN number.


Why, and how to increase 16-character lockscreen password limit? This is a problem that has annoyed me, as the password that I have memorized is around the 20-character mark, yet Android limits it to 16 characters

Why, and how to increase, 16-character lockscreen password limit?

If it's relevant, the Android is running on 5.1 Lollipop.

From Android Security Internals: An In-Depth Guide to Android's Security :

  Android doesn’t have a dedicated setting to manage the encryption pass-
  word after the device is encrypted, and changing the screen lock password or
  PIN will also silently change the device encryption password. This is most
  probably a usability-driven decision: most users would be confused by having
  to remember and enter two different passwords at different times and would
  probably quickly forget the less frequently used, and possibly more complex,
  disk encryption password. While this design is good for usability, it effectively
  forces users to use a simple disk encryption password, because they have to
  enter it each time they unlock the device, usually dozens of times a day. No
  one wants to enter a complex password that many times, and thus most users
  opt for a simple numeric PIN (unless a device policy requires otherwise)

  Additionally, passwords are limited to
  16 characters (a limit that is hardwired
  in the framework and not configurable), so using a passphrase is not an
  option

(Emphasis supplied)

I don't know more about this limitation and would be glad if somebody can amplify (Edit: Andrew T has clarified here to an extent)

So, that rules out increasing password length to beyond 16 ( how to increase, Androids 16 character lockscreen password limit )

Since you are on Lollipop , you may like to related pitfall (claimed to be fixed) of long passwords here Android lockscreen can be bypassed by overloading with massive password

Note:

For earlier versions (Lollipop and below), Cryptfs Password by Nikolay Elenkov, allows you to set a separate password for disk encryption or if your device is rooted

su -c vdc cryptfs changepw new where new is your new  password.

Square dot between two square brackets notification icon? The icon looks like a square dot in middle and two square brackets surrounding it.

I tried looking for the icon on Google but couldn't find it.

How can I removes it and what is it?
E.D.I.T.  The icon is like [[•]] the dot is square its on system side. It appears and goes automatically. Dont know how to add screenshot. I am new here.Device is Yu Yureka Plus Running Cyanogen 12.1 and lollipop 5.1.1

What happens when using a cellphone when charging? What happens when a phone is being used with the charger connected?

Will it take power from charger and save the battery usage?

OR

At one end, the charger keeps charging the battery and at the other
end, phone discharges the battery simultaneously?

(I am using Sony Xperia SP with Android 4.2.1)

As using the device also uses some power, the device cannot "charge with the normal speed" at the same time. It will however primarily use the external power source for its consumption. Depending on whether you "consume" more power than the source can feed, either it compensates by taking whatever is needed additionally from the battery, or feeds whatever is left to it.

A side effect described in the other answers already is true, however: the device will get "warmer" this way. I already described that in another answer:

  Recommendation for cold days to get warm fingers: Take your device with both hands, plug in the charger. Now stream a HD video from youtube via 3G, play it fullsize, and in the background do some video recording which in parallel gets uploaded via 3G. CAREFUL !!! Wear gloves... #-)


Is it possible to create a plain text file in android? I see lots of apps that can create "files that contain text", but the files are in their own proprietary format.
I would like to create a plain text file so that if the file is transferred to a computer, it could be opened using a common text editor, like notepad or gedit etc.
Is this possible?

device

Samsung galaxy note 2
running android 4.4.2

You can easily create a plain text file in Android which can be opened by editors like Notepad, Wordpad, Gedit, Kate, etc. in PC. I use 920 text editor (hasn't been updated since ages) for such and use them in Kate editor of KDE Plasma in Slackware GNU/Linux (Also tested in Windows and Ubuntu). You may use any other editor of your choice. See this answer or the various text editors listed here on Play Store.

Other than that, ES File Explorer File Manager also allows creating and editing a text file.

Launch it → New → File → name the file with .txt at the end → open it as text with ES Note Editor.

In addition, if your device is mounted in your PC via USB Storage, or is accessible via MTP/FTP/(a server), then you can use default mechanism of the desktop OS to create a text file in Android. (I do a lot of editing over FTP.)


Can not uninstall an app(hi app lock) which has device administrator rights I have installed "hi app lock" application 2 year ago. But rarely used it. Now when i open it, it doesn't open. So i decided to uninstall it, but first i have to revoke its administration rights. So i try to unchecked it, but that action is crashing. Attached image of uninstall steps. Please let me know how to remove this app. I don't want to factory reset or root my android device(oneplus one, OS: Cynogen OS version: 13.2.1....)

After viewing report's call stack, got to know that android.permission.SYSTEM_ALERT_WINDOW

for this app is not enabled. So, i enabled above setting by help of this link, https://www.experts-exchange.com/questions/28947878/How-to-enable-android-permission-SYSTEM-ALERT-WINDOW-in-marshmallow.html and then successfully revoke device administrator right and uninstalled it.


OpenGL apps not responding to touch on Xperia M2 I have a Sony Xperia M2 (not rooted, on stock 4.3 Jellybean). When installing some apps, I noticed they won't respond to touches. After installing a few more apps it became apparent that the apps that didn't respond to touches all used OpenGL. Other apps work perfectly, but ones with OpenGL get stuck.

The apps aren't frozen because any background animations they have still work fine.

With developer mode visual touch feedback enabled, my touches show up on screen, so I know android still registers them.

What's going on, and how do I fix this?
Also, will updating to KitKat affect this in any way?

I updated to 4.4 KitKat and the problem seemed to have been solved. All OpenGL apps now work like normal.


What is the difference between the Android OS and Android System? When I open my Battery Usage, there are two components enlisted as Android OS and Android System. What is the difference between these two?

"I got a rather meaningful suggestion on another forum that "Android OS" is actually the low-level kernel, while "Android System" is actually the higher-level OS service layer"

how to install Samsung apps on other androids hey guys i really need Samsung voice recorder to work on my oneplus 7 pro but it doesn't work. Samsung limits it to only Samsung devices. any way to run it on other androids? i tried apk but doesn't work

Samsung devices have not only just a GUI that is a little bit different but the changes Samsung makes go deeper. This goes down to the available libraries and APIs an app can use. They add proprietary features and libraries and if a Samsung specific app uses those features you simply can't install it on a non-Samsung phone unless you have heavily modified the ROM.
The app "Samsung Voice Recorder" is a Samsung specific app that only works on Samsung devices.
I have checked version v21.1.06.11 as provided by ApkPure. This app defines in it's AndroidManifest.xml that it requires the following Samsung specific features:
<uses-feature android:name="com.samsung.android.feature.resopt" android:required="false"/>
<uses-feature android:name="com.samsung.feature.device_category_phone"/>
<uses-feature android:name="com.samsung.android.api.version.2801"/>
<uses-feature android:name="com.samsung.feature.samsung_experience_mobile"/>

Only one of those features is optionally (require=false) but the other three are mandatory.
Note that features are device/ROM specific features, you can't just pretend that your device has those features.
Therefore to make this app work on non-Samsung phones you would have build a custom ROM that includes these features (usually special Java/DEX libraries plus the native libraries and potential device drivers, ...).


Factory reset left root intact? I rooted my Dream/G1 last night and finally gave up on modding it (not for good mind you, but for the moment) and opted instead to just restore it to factory settings via Settings > SD card & phone storage > Factory data reset, which did solve all the problems I was having with multitasking (and not being able to answer it, etc.)

Curiously, I still seem to have root on the phone, despite having reset it. I'd love to understand how that is possible! Superuser Permissions is the only non-stock app still on the phone, and I'm still able to use su to gain root privileges from adb shell. Is this because BusyBox installs to my SD Card?

My phone works just fine, so this is hardly critical, but the whole exercise was/is about knowing my phone better and this is most def. a mystery. Thanks!

Root things (su, busybox and Superuser.apk) are installed in /system, which is usually on a special partition. This partition is usually mounted as read-only. (Remember mount command, that is neccesary to allow writing there...) It is likely that this partition is not affected by master reset.


Restore app data backup without access to usb debugging Google backup didn't work, and I tried Helium, but you have to connect to usb debugging in order to "enable" it. I have access to usb debugging on the phone i'm backing up, so I have the data, but my new phone only came with a usb-c to usb-c cable, and I can't get a usb-c to usb-a cable for a few more days, but I need my phone to be set up much sooner than that.

Is there any way I can restore that app data in my current situation?

Since *.ab is an Android adb backup file you will have to do it via adb, but since you don't have the correct cord you will have to do it wirelessly.

Instructions to setup wireless adb:

Download WiFi ADB - Debug Over Air and install
Turn on your wifi and connect your phone and your computer to the same network.
The app will run you through the rest of the setup process.
Once setup try "adb devices" , if this works then you are connected and you'll be able to restore the way you normaly do via adb (but wirelessly).

Hopes this helps you overcome your problem of no cord.


Android tablet not recognizing external keyboard? I have a Tablet running Android 4.0.3. Its DOMO x3g, works fine except that when I connect an external usb keyboard to it,it doesn't show up any recognition or anything.While USB pen drives, hard drives easily work on the tab... Any solutions?

Yes, I had the same issue, it never worked for any PC USB Keyboards, except the one which we bought from DOMO, that nCase K6. That K6 worked perfectly (even to my PC). But a PC USB mouse worked on my DOMO Slate X3G. Buy a nCase K6 or, preferably you could install USB Host Controller from Play Store, as said by the first answer.. That should fix your issues.


How can I prevent installation of NEW applications on an Android 5.1 device, but keep auto-updates of existing applications? We will soon have to provide a phone to a person who is obviously not familiar with IT stuff at all, and not capable of learning anything about information security, etc. (and probably not capable of learning anything really) They must have ability to communicate with us and there will be no one near them to "repair" the device in case something gets really broken.
I thought that it will be a good idea to provide them with a couple of necessary applications on the device and then block installation of any other new apps (both from Google Play and from anywhere else). However, the standard auto-update process of Google Play should be working (at least because otherwise messaging/VoIP apps will soon become obsolete and stop working, and for security reasons, too)
So the question is — what are the possible solutions to prevent the user from installing non white-listed applications?
Also, we think that the person will not try too hard to circumvent the restrictions. So, maybe even a simple solution (just hide all unwanted icons, including Google Play, from the launcher / app list) will do, but this is risky, and I am not sure that is possible with all kinds of stock UI. So it's interesting to know if there are any better solutions.
Update
Solutions which do not rely on the fact that the user doesn't know (their only) PIN/password are preferable, because a working screen lock can be useful to reduce damage caused by device loss/stealing.

There are multiple approaches you could take:

a kiosk-mode solution. That would pin the user to a certain app or group of apps defined as "kiosk"
parental-control apps, which are often a specific variant of kiosk
use an App-Locker

The latter most likely is the approach best fitting your current case: You can define which apps should be "locked down" and which not. Locking e.g. settings and the Playstore app, while unknown-sources are disabled, would prevent any new installations. With auto-updates enabled in the Playstore app, these would still be applied automatically.

For additional details, be welcome to click the tags (for questions using them), or take a look into the corresponding tag-wikis: kiosk-mode, parental-control, unknown-sources.

Note that, to prevent installations via the Google Play web interface, the user must not have the credentials of any Google account linked to the device (no chance otherwise).1 These do not necessarily correspond with the lockscreen PIN/password/pattern, so this is no contradiction to your requirements.

Mirror Android Tablet to VGA monitor via Cable- NO DiSPLAY Specs:  Samsung Monitor S222B300B,
        Samsung GalaxyTab 2 (micro usb slot),
        Monitor cable,
        Male micro usb to Female HDMI w/usb power slot,
        Male HDMI to Female VGA port

notes: all connections has been connected, power was switched on the monitor, power on the male micro usb to female hdmi cable was plugged, monitor tested with laptop to display screen and working fine

problem: monitor does not mirror tablet's screen which should easily be detected but it does not.

question: i bought the 2 sets of conectoon cables thinking there might be a defect 2nd one - same thing. does my monitor have a problem or does all monitors works for this kind of set up? is there anyhting that i should have done to make it work?

hoping for someone's help. getting me crazy. iwanted to watch on a bigger screen dont like wireless options for the meantime.

If you have a computer hooked up to that monitor, and can hook up your phone via USB to the computer, I recommend Vysor. It's available as a chrome or windows app. Works great for screen mirroring, and the free version only uses USB

Note that there is a pro version of it, but basic functionality is free. You may also need USB debugging and ADB working


Does an Android Factory Reset also clear the cache partition? In researching a possible answer to this question about "Server error occurred. Restart Camera." while taking photos on the Samsung Galaxy S6, I read this article.

The article talks about wiping the cache partition via Android System Recovery and performing a Factory Reset.

Question: Does an Android Factory Reset also clear the cache partition?  Or does it only clear the data partition?

Yes, a factory reset clear's the cache, dalvik cache, along with the user data.

<string name="factory_reset1">Wipes Data, Cache, and Dalvik</string>

The information on factory reset is hidden in the Source code.


Multiple uses for NFC I have my bank card linked to my NFC and since this day it is also possible to have my public transit card assigned to my NFC-chip. The thing I want to know is, is it possible to have multiple functions for your NFC-chip, like in my situation.

If needed, my bank is the ING-bank and my public transit card is from Translink.

I'm not sure what exactly you want to do but still here a suggestion:

With the App Trigger you can run two actions alternately. You can have various restrictions, maybe one of them is useful to decide which task you want to run.


Bypass Pattern lock without minimum or no touch of mobile I have android mobile with Android Lollipop 5.1.1 and I want to unlock the mobile without working on mobile. I had added pattern before screen damage.

Phone details:

Touch of mobile is damages and I can hardly use touch so working on cell is not possible. (I believe) I can type digit 3 on cell.
I tried to unlock device with ADM (http://trendblog.net/how-to-bypass-android-phone-lock-screen-pattern-pin-password/) but cell dont display option to fill pin to unlock
I have access to Google account and can install any apps.
Memory card can be inserted into mobile.
Internet is working on my cell.

I can do below thing with touch:

I can drag-down the top notification area of cell.
I can enable/disable hot-spot of cell.
I can receive calls on cell.

Please ask in comments if more details are required.

  In summary, I want to unlock or bypass pattern of mobile by using
  computer or USB or Google account. How it can be possible and I want
  to do without factory reset?

I found the solution for this problem.I purchased a OTG cable and connected my mouse. I easily unlock the pattern and can do all things with mouse from typing to call etc.

Now i can access my cell with mouse till i get confirmation from service center about availability of touch combo :)


What exactly is framework-res.apk As far as I understand it, it is a big system file that apparently controls a big part of the phone. I am interested because I wanted to do some themeing and so far I had edited SystemUI.apk, but if I ever ran into any problems (and being a beginner that was bound to happen) nothing seemed to happen other than the fact that I lost my notification bar.

Problem is, I have heard of some people who touched framework-res.apk and they wound up not being able to even boot their phone. I decided before carelessly poking around with something that could potentially soft brick my phone, I would like to learn a bit more about it.

So what exactly is framework-res.apk? What is it used for? What does it control? Where do we visually see its use? What could potentially happen to my phone should something go amiss with framework-res? Anything else I should know before poking my nose where it shouldn't be?

Framework-res.apk basically contains the elements of the Graphical User Interface for the phone. This file is available at /system/framework/framework-res.apk.

Poking in this file would mean changing the complete look and feel of your device. Since it is the main element of your screen, replacing it directly by pushing it through ADB would lead to soft-brick. Therefore, this apk should carefully be modified and replaced using the recovery module of the phone.

Check this link for details on the same: Modifying the framework-res.apk (Theming the UI)


How to install new Recovery image from .img file I recently found that I could upgrade to the new CWM touch recovery version for my EVO 4g! However, to do this through the ROM manager app or get it directly onto the phone at all, it required a payment, although they specified it could be found (the same version) for free on their website. So naturally, I went and downloaded it as soon as I could.

But instead of a .zip file, as things that I usually flash, it is an .img file. This made sense, since I figured I wouldn't be installing a new recovery through the current recovery version, but I am unknowing as to how to install this new recovery image.

Anyone know what my next step is?

If you have a fastboot-enabled bootloader version (such as the old 0.76.0000 engineering HBOOT in the EVO's case) you can use that to flash it from a PC via USB. Reboot into your bootloader, then select the "Fastboot" option from the boot menu (if it has one, it may start up fastboot automatically). Once it's ready, go to your PC's shell and execute:

fastboot flash recovery /path/to/recovery.img

You should also be able to use the flash_image binary if your ROM has it (or you install it from XDA). Copy the recovery.img over to your device somewhere then do the following:

C:> adb shell
$ su
# flash_image recovery /path/to/recovery.img


Will google accounts automatically update my friends addressbooks I was with Verizon Wireless when I had my HTC Eris (now due to issue with VZW and upgrading my phone I cancelled with VZW). I moved over to sprint and to a phone OS that shall not be named, but now I am on the verge of getting the Samsung Galaxy S4. During my switch, I did NOT keep my phone number and took a new number with Sprint. The problem is that my friends may still have my old number in their Google contacts and I am concerned that switching on the Galaxy S4 would cause Google to update my number to anyone who has my number in their Google contacts.

So my question is, if I link my Google account on to my new carrier/device, will Google update anyone who has my number in their Google contacts automatically?

NO. Their contact list (that is synced with the Google account) is based on the GMail contact list. It is a local copy; so any changes must be made from their side.

However, if they synced/merged that GMail contact to your Google Plus account, and you updated your contact information in Google Plus, it's still possible for them to know your new number.


Update review on Google Play after refund Yesterday I've downloaded a paid app from Google Play store but it didn't work as I expected so I gave it a 1 star rate and I asked for a refund.

Then i've read again the app description and I realized I did wrong assumption about how it gotta work.

Now I would like to remove or at least update the review I did because it was my bad and the app got no trouble at all.

Apparently I cannot do it and the bad review will stay there forever.

Any idea about how to fix this?

Do you think Google should give the chance to update reviews despite refund?

Thank you

Found this page that seems to address your issue. Maybe try to delete the review whilst on your computer if you've been trying on your phone or vice versa. It does say ''Note: You can only review apps you have previously downloaded and installed. When you download an app, it's linked to your Google Account. '' I'm wondering if the link between your account and the app is only deleted if the app was a paid app. Because I have previously downloaded free apps then deleted them from my device and the link between my account and the app is still present.

Hope this helped

Samsung Galaxy S phone USB device recognized by host VirtualBox OS but undefined in guest OS My phone model is

  Samsung Galaxy

  S SGH-T959

When plugged in via USB cable, the phone is well recognized by Windows as below snapshot.

But when I select the Samsung phone device from Device menu of the  VirtualBox guest OS window as below snapshot, the device is not regconized after Windows try to auto update driver for that device :(

Is the USB icon on the VirtualBox enabled on the guest OS.

If that's disabled, the USB on the host side will not pass it through the guest, this requires the handset plugged in host side.

It's a small icon on the bottom of the VM window, near the hard disk where it shows blinking activity? Click on that, to enable USB pass-through.

Are you intending to flash the device from within a VM?


I have bought a new mi 5 mobile My older phone internet was too fast. When I transferred my sim into new phone, the internet is too damn slow. It's slower than tortoise. What should I do?

The only thing I can suggest is to check and make sure that your phone is set to 4G (preferred) mode in Network settings.

Another thing worth considering is to check with your operator that the correct access point is being used.

And can you tell which was your previous phone? Depending on the device and its OS, it is very possible that it consumed lesser data whereas your Android's browser uses more data. Consider using Opera Mini or other browsers which compress pages before delivering to your device.


Can I get DLNA on my Droid? Can I get DLNA on my Droid 1 through some sort of hack, patch or accessory or do I just have to upgrade to a newer phone?

I'm sure this question must seem absurd to some people but I looked around and it's still not clear to me if DLNA is a software or hardware solution.

Twonky media, who make the very good Twonky DLNA server for PCs, have released a Twonky Server app for Android, this should allow you to share content (videos, music, pictures) that are stored on your phone to network attached DLNA compatible devices on your network (eg Windows Media Player on Windows 7, XBox 360, PS3, specialised set-top boxes, some new TVs).

Also, I don't know if it's carrier specific but my Samsung Galaxy S came with the AllShare app (which I haven't used yet) that claims to be a DLNA server and client. Can't find it in the Market, so I assume its Samsung only.


What is the address for internal storage on browser? If file:///sdcard/ is the access address for the SD card, then what is the address for internal storage on my HTC?

You probably won't be able to access much of your internal storage via the web browser. The URL you mentioned, file:///sdcard/, consists of two parts: the protocol (file://), and the path (/sdcard/). So basically, you just have to change the path accordingly. You can check with a file manager what the path to the desired destination is.


What icons are these? What icons are these?

Not sure if these can be seen well enough.

The one on the left is a notification about a potential power or memory hungry app that could be put to sleep temporarily. The one on the right is probably a suggestion notification from Google Maps.


Out of space message although I'm using link2sd! I've Android 2.1 (Sony Ericsson Xperia X8) so I'm using link2sd becasue many apps need some extra space but OsmAnd always shows "Out of space" message.

How can I fix space issue?

P.S.

link2sd works fine.
I've 64.13MB of free space in the internal storage and 4.61GB in the 1st SD card partition and 2.18GB in the 2nd SD card partition.
The size of OsmAnd apk is: 16.5MB

I don't know how much the installed size of the app is. But considering how the install process works, the explanation might be easy:

the .apk is downloaded to /data/local (internal storage)
for installation, it might require some unpacking, with temporary files again being created on internal storage
only after that, the app will be stored to its final location (in your case, Link2SD would then take care to move things to your card)

Checking with our insufficient-memory tag-wiki, you will find that the "insufficient memory" error is triggered when available free space on internal storage falls below ~ 25 MB. Now let's make a little math: You've got ~64 MB free there. The .apk is ~18 MB. We need to leave ~25 MB to not trigger the error. So: 64 - 18 - 25 = 21. If the installation process requires more than 21 MB for temporary files, you've got your explanation. With the (packed) .apk file already being 18+ MB in size, it's very likely to break that limit.

For a possible work-around, you might want to take a look at Configure Play Store to download temporary files to SD Card.


Terminal emulator's ssh trying to read /data/.ssh instead of $HOME/.ssh When I try using Terminal emulator's ssh I get

  ssh: Warning: failed creating /data/.ssh: Permission denied.

or since 2012-08-19:

  Could not create directory '/data/ssh_client'.

But when I type:

echo $HOME
/sdcard

Why isn't ssh checking /sdcard/.ssh or /sdcard/ssh_data?

This doesn't happen when you run ssh as root.
/sdcard is an unsafe(!) location for ssh client config and valuable keys (some users don't even encrypt their keys for reasons of laziness). Each app has read access to that location, so this is most probably set deliberately not to /sdcard/.ssh for security reasons.
If you have root access, create a symlink from /data/ssh_data or /data/.ssh to /data/jackpal.androidterm/ or create the folder with appropriate access rights for the terminal app (not system wide read/write though!).
By the way:
This might be fixed soon. See CyanogenMod's github commit log here. Excerpt:

Some users have / as home directory, some /data. This commit fixes ssh
and ssh-keygen trying to create /.ssh which is volatile and read-only
anyway.
To allow an app (e.g. Android Terminal Emulator) to use ssh
/data/ssh_client still has to exist and owner permissions need to be
set to the app user. This could be fixed by using the real data
directory (/data/data/"app") in a later commit.


Nexus 7 won't boot up after the colorful X My Nexus 7 will not boot up past the start-up animation (colorful X)-it's not a power problem as it charges up OK-just will not get past the X. I've powered it up and down several times but it hasn't solved the problem.

I had a similar issue - only seemed to happen when power had got really low and wifi was on. the way I got around it was:

Connect to charger
Shut down nexus
Hold "volume down" and power button until it wakes up
On the bootloader screen, press up until it says "recovery mode"
Press power
You should see the Android logo with a red exclamation mark
Press and hold power, and then press "volume up" which should take you to the recovery menu.
Once in recovery mode, leave plugged in and fully charge (several hours).
Once fully charged shut down and restart and it should get past the X.

Good luck!


Is it possible to cancel out echo when using a bluetooth handsfree? Equipment used:
I just bought a cheap Bluetooth handsfree from china: http://www.miniinthebox.com/mini-stereo-wireless-v3-0-headset_p1187467.html

Explanation:
This works perfect for me, and i don't notice any problems at all.
The problem is that for people calling me, or i am calling hears them selves in an echo with about 1 sec lag.

I cannot hear this echo at all, but for everyone i talk to with the handsfree set hears this echo.

If i mute the mic, then the echo disappears.

My question is this: Is it possible to remove echo by using any software or android setting?

I think that there should be two ways of doing this:

1. muting my mic while the other part talks. (nearly like an automatic walkie talkie)

2. cancelling what is sent from the other part, and don't send the same sounds back to the other part again.

This is pretty hard to do with software, since there are delays in the audio stream. The transmission from you phone's BT to the headset can take up to 200ms, and the same for the reverse. Therefore before sending the audio from the mic to the recipient, up to 400ms of audio would have to be sampled and cancelled, assuming that the BT connection is stable.

Usually this is done in the BT headset itself, but, as you said, it's a cheap Chinese headset, so the circuits for this have been left out.

As far as I know, the only settings in Android regarding noise cancellation support only on-board noise cancellation mics.

As for the muting solution, some phones use compression to boost the mic strenth, which will raise the noise levels when the person is silent. This would cause the mute to be always on.


What is the effect of "power saving mode"? Android OS from ICS and above has a "power saver mode" by default (I own a samsung)
What does this mode actually do?

If it reduces clock speed of cpu, then by how much?

How does it attain this power saving? By limiting cpu? Gpu?

I think this is a manufacturer specific feature, not an Android feature.

My Nexus 4 running 4.4 has no power saver mode.

My HTC One running 4.4 does have a power saver mode and although I can choose what aspects of the phone I want to limit to conserve power, I am not told how / what they do to save the power. I guess this will be chosen and set per manufacturer but for example, on my HTC device in power saver mode the options are;

CPU Power
Conserve CPU usage

Display
Reduce screen brightness

Vibration
Turn off vibration feedback

Data connection
Put to sleep when screen is off

Have you had a look in your settings menu? It may well tell you in there what is being limited.


Can't save proxy settings after installing AdBlock Plus I installed the AdBlock Plus app and I need to modify the proxy settings, but the "Save" button is disabled and I cannot do anything. Could you please help me out? I have an LG P970 running Android 4.0 ICS.

Screenshot (click image for larger variant)

Its not about adblock i guess.
Its is just that you have to give proxy server ip instead of hostname ( it looks something like 10.X.X.X ). it will enable save button.
So you put that ip in proxy hostname and save button will be enabled.
( It worked for me in my android)


What is the name of the GUI Android uses/has used? Like the GUI controlling home screen and app icons, etc.
How or what is this called that renders this?

It gets the name of the Android OEM front end interface :

Touchwiz for Samsung
HTC Sense for HTC
MotoBlur for Motorola
...

For the "basic" version of Android - i.e. the version embedded in Nexus phones and tablets - people often refer to the Android version as "stock Android". So what about "stock Android UI" or "stock UI" in this case ?


PIN longer than 16 digits I was wondering if there was any way to use an unlock PIN longer than 16 digits on android lollipop - in the settings it allows you to enter a PIN less than 17 digits. I would like to stay away from 3rd party lock screens if possible. I am running resurrection remix (Lollipop 5.1.1).

Thanks

Far as I know, no. Now of course wait for more answers but far as I know, if it is set to be 16 characters max it means it is a 128 bit variable. If that is all Android has saved for the PIN, then that is that.


What happens with the installed apps when you switch Google Account on a phone? I am going to buy a new Android phone.

I would like to give my current one to my wife when I do this. She already owns an Android phone so she has her own Google account.

I am just wondering what happens if I switch Android account to my current phone. Will she be able to use the installed apps or only the ones she bought also?

Or does she lose the ability to upgrade the apps, but can she still use the ones already present?

Apps are linked to the account that downloaded them, but Android has adapted, and will recognize the apps that are installed, regardless of which account is on the phone. This means:

Your apps will not be deleted from the phone if you switch accounts
You will still be able to update apps
You will not be able to use any apps that were purchased through the other account. They will remain on your device, but most apps check for validation in the Play Store when they start, and will not allow you to run them if you have removed the account they were purchased in.

ALTHOUGH: You can use them if you leave the other account logged in on the device, they will just be managed by that account in the Play Store. You can switch accounts to manage apps for either by pressing Menu in the Play Store and selecting Accounts and choosing the account with the apps you wish to manage. Then choose My Apps from the Menu after you have switched accounts.

HTC STATUS-INTERNAL MEMORY LOW EVEN WITH SD-CARD? Possible Duplicate:
  What can I do to manage my phone's internal storage?

I have the  HTC Status, and love it!  But lately I'm getting "Internal memory low" messages when I try to open or download something in my messages.   It tells me to go to the "settings" tab and make space.  I don't have many Apps on it, the biggest I believe is the FB App-but it's the so called "FB Phone" so why am I still having issues?  I uninstall and delete data and try to move things to the sd-card and empty inboxes all the time and it just moves a few MB and leaves me alone.  It gets bad sometimes, where it won't let me even ope and read a text even if there aren't any pics to load.  Any help would be greatly appreciated!

The sdcard is not included with internal memory. What it is actually complaining about is the location where the data and apps are stored (/data & /data/data) and could also include the cache (/cache). I have been saying for a while that more space needs to be allocated for these locations.

I have to go through and remove some apps some times, and even go to apps like Google+ and "clear data". Google+ is actually a good example of a data hog. I had to clear it today. Google+ was using 42MB of storage.

The best thing that I can suggest is to clear the data on apps that are "hogs" or remove apps that you don't use.


sending AT command with NCK code unlock sim? I need information. How can I send the NCK unlock code network using AT commands? Or is there any other ways?

Depends on the who made the phone and the AT command set they support.  I did this recently on a ZTE Modem using AT+ZNCK I believe, but that command isn't a standard one across all manufacturers!  Trying to do it again on an LG, no good luck so far.


How can I import / export contacts as VCF in Sony Xperia Tipo Dual I'm using a Sony Xperia Tipo Dual with ICS. I need to backup my contacts with or without linked contacts.

Does anyone know the exact procedure to export contacts in VCF format; either directly to PC using PC companion or to SD Card using any third party free application?

In addition to that, I want to know if it would be possible to add / update contacts on the mobile through the Sony PC companion?

I am guessing that you are running Sony's TimeScape Interface. (As you not mentioned anything explicitly) So here are steps:

To back up contacts using a memory card:

From the Home screen, tap the Application screens icon.
Find and tap Contacts.
Press the Menu key, then tap Back up contacts > Memory card > OK.

Tested on Xperia Neo, Xperia Neo V, Xperia Ray running 2.3.4 Gingerbread to 4.0.4 ICS with Sony's TimeScape UI. Should work on Tipo as well.

Here's a page from Sony's site for further help.

Will rooting my Samsung Galaxy S before I activate it cause any problems? I have a samsung Galaxy S (Fascinate) that I haven't decided if I want to keep, so I haven't activated it on my Verizon account. I'd like to root it and flash a new ROM (possibly a separate Kernel) but I'm wondering if doing so when it is not connected to any carrier will cause any problems, particularly with the voice/data connection settings?

I doubt it.  I've done the same with a GSM Galaxy S (the Vibrant) with no problems.  Of course it probably depends on whether you have a really terrible ROM, but rooting alone shouldn't matter.  And it might be different for CDMA.  But worst case, you can just flash back to stock.  My Vibrant picked up the network settings on it's first boot with a SIM, I would again assume your first boot-up after activation would cause the same thing.  Plus, if the custom ROM is Captivate-based and not i9000-based, it might have the network settings already built in (and just need to pick up the phone number).
