Drag'n'drop event moving gone in Calendar... again Google Calendar's event's drag'n'drop functionality stopped working... again, after nearly exactly two years since previous report. Tried to restart both Google Calendar and phone itself (Motorola Moto Z2 Play with Android 8.0.0), cleared app cache and then data, without any results.
I did very little to my phone before that happened:

no configuration changed,
nothing actually doing with my phone.

I have only installed one new up -- FakeStandby -- as suggested here, but since this app has nothing to do with the calendar itself, I would be surprised, if that would be a source of the problem.
To clarify problem:
On a day view (not: agenda) long-pressing any event now brings no effect. Previously it caused an event box to be risen up visually above others, and moving finger around screen allowed to move event to some other hour or day. Now, drag'n'drop functionality does not exist / does nothing.
Is there any know report about some bug, bug's regression or is this a generally known problem? Or is this again my stupid phone going wako in exactly the same way during second anniversary of the moment, this problem appeared for the first time?
EDIT: From what I have learned, when Calendar becomes "locked" (no event's drag'n'drop) all items in calendar are visually more flat than usual. When functionality "returns" they again become a little bit 3D-like.

On contrary to initial believes, it was (is) FakeStandby that is causing these problems!
This app is designed to FakeStandby mode, by turning off screen, but not causing actual standby mode. This causes that all other apps are not notified about phone being in standby and continue working in background (below FakeStandby).
To achieve this, FakeStandby must be able to control all apps (at least that's what its author claims). And in order to do so, it adds itself to the "Accessibility" section of the configuration:

And... that's all. Having FakeStandby Service turned off causes Google Calendar application to lose / disable / turn off event's drag'n'drop functionality. Why? Unfortunately, I have no idea.
The simplest workaround -- for having Google Calendar's full functionality and not being forced to uninstall FakeStandby -- is to kill this app after each use. Long-press on its icon > App Info > Force Stop does the magic. Until next run of FakeStandby, Google Calendar will have full functionality.
Since this is a system service, killing it with Force Stop will also automatically reset its setting in Accessibility > Downloaded Services to Off. When you run FakeStandby next time and attempt to activate it (by pressing its button on the right side of the screen) you will see a message:

If this is too annoying for you or impractical, because you're using FakeStandby too often then I think there is no other option rather than a split decision:

find some FakeStandby replacement or
stop using drag'n'drop functionality in Google Calendar.

I am pretty sure that this is some kind of bug in FakeStandby itself, not in Google Calendar. As I have two other apps listed in Accessibility > Downloaded Services (namely: Nova Launcher and Kaspersky Safe Kids). Both apps has their setting set to Off by default (because ability to observe screen and control other apps is used in them only in a rare, specific scenarios).
But, I have just managed to test that setting it to On for any of these two does not cause described problems with Google Calendar. So this got to be "something" in between FakeStandby and Oreo (I have no ability to test this issue in other versions of Android system).


Can't set picture in Android Quick Setting I want my Google Plus profile picture to appear in notifications Quick settings area, Prior to this update it used to work by going to google plus app> settings> contacts > then ticking two options that I can't remember. But those options are gone now.

I'm using a custom ROM (which doesn't seem to be an issue)

Rom I'm using is DarkRom caf
Android 7.1.2 (may security update)
Based On Lineage 14.1

As of some version from may, the contact option was removed mysterously by google. Maybe they are going to reintroduce it by some other mechanism. But for now, you'll need to download  the g+ app prior to may (you can get legit apks from apkmirror). Then enable the contact sync from that. Post which, you can upgrade to the latest g+ version


Speed of WiFi file transfer from PC to phone I have WiFi router set up. Both my phone and Windows PC connects to the same WiFi. So I tried ES File Explorer to copy shared folders from my Windows PC to my mobile.
However transfer speed goes as high as 570 KB/s but not more than that. Since I configured my WiFi router to allow speed as high as 300 Mbps I am guessing why it cant hit the Mbps speeds. What can I do improve on my speed since I move movies worth in GBs and it takes almost an hour or more. Is it limited by the speed of the mobile and its internals?

Your phone seems to be a bit older as it runs Android 2.3 - therefore I assume it does not support any faster WLAN connection than 54MBit.

Hence the theoretical maximum would be 54MBit = 6.75 MByte/sec but only if you have just a router and a phone. With your PC in the network each device gets less than that.

Depending on the network protocol used you also lose a lot of speed. SMB/CIFS as used by Windows shares is very ineffective. Better use FTP protocol and suitable client for the best speed.

If that does not improve the performance I would suggest using an sd-card in and sd-card reader directly attached via USB 2.0 to your PC.


S6 keeps turning off My girlfriend has a Samsung Galaxy S6 that keeps turning itself off randomly multiple times a day (not rebooting). The only way to turn it back on again is to hold down the power and volume buttons. Has anyone else had this problem? Or more importantly has anyone got a solution?

Backup your data
Flash last firmware with Odin
Do not install any app

Check it again if turning off happened again, Its hardware relative and you should send it for repair.

I think flash firmware will fix your issue.


Why do phones need an OTA update to support VoLTE for certain carriers but they work out of the box for other VoLTE carriers? This is regarding unlocked phones sold from stores. A major carrier in my country depoloyed a VoLTE network and it worked even on custom ROMs with very minor problems. Now 2 other carriers are following suit but they had to work with phone manufacturers to release an OTA update so VoLTE would be supported by the phones on their network too. Isn't VoLTE a standardized protocol? Why do phones need updates for another VoLTE carrier even though the phone supports VoLTE in another carrier. Isn't it just a matter of changing APNs?

VOLTE is a standard. And like all standards the devil lies in details of implementation. Carriers may choose different implementation for various reasons

Section 2.2.1 of PDF document here
offers reasons as to why implementation differs and hence updates are needed

  ....VoLTE interoperability issues might be related to EPS bearer set up, proprietary simplification of SIP call flows, operator specific IP headers, different security configurations IPsec, AKA etc.

You have detailed technical reasons explained subsequently in the document


Swap first and last name in contacts As I could not see SIM card contacts in my contacts app, I just imported all contacts (well over a hundred items) from my SIM card to Google account.

On my SIM, my contacts were stored as Last- First-name (for sorting). And all this was imported, but Google assumes it's in First- Lastname format.

I need some way to fix this, as this issue messes sorting contacts - some are by first, some by last name. I don't want to go and fix all of those by hand, as it is well over a hundred contacts.

I am using Cyanogen based on Lollipop 5.1 (OnePlus One)

Note: Please take a backup of all your Google contacts using the old Google contacts website either as a Google .csv file or .vcf format before trying this and use an app like Super Backup : SMS & Contacts for exporting your phone contacts just in case.

As I've already mentioned in my comments you can try this,

  First take a backup of all your google contacts(Export as ->Google
  .csv). Then download the Outlook .csv export and replace the First
  name column with the Last name fields and vice versa using Microsoft
  Excel. Import the .csv again to your Google account and check if
  the sorting is they way you wanted. (Last-First-name).

Alternatively you can also try this google forum post (if the above doesn't work),

  Go to contacts
  Select All
  Export to a Google csv format file
  BACKUP that file !!!!!! <- This is the most important step of the process!
  Open the csv file you have just created using Excel (maybe there are other tools - that's what I used)
  Create a new sheet (call it temp)
  Copy the first column from sheet "Contacts" to sheet "temp" (Column Name: "Name")
  In the "temp" sheet, select the only column (name) and go to Data->Text to Colums->Delimited->Next->space->next->finish
  At this point the names and family names should appear in different columns
  Check that there are no people w/ more than 2 names.
    If so, you will need to decide where to put the 3rd string so you stay w/ 2 columns only.
  In Cell C1, write down "Name"
  In Cell C2, write down the following:   =CONCATENATE(B2," ", A2)
  Copy this field to all cells in Column C
     Now Column C should be filled with all names in the form of "Family Given".
  Copy column C in sheet "temp" and paste it with Edit->Paste Special->Paste->Values to Column A in sheet "contacts".
  Delete "temp" sheet
  Save the file w/ a new name (newContacts)
  Back to Gmail, delete all the contacts (not before you are sure you've saved that first file!!!!!)
  Import the new CSV file.

The OP of the above message said it worked for him very well.


Extract app name from app-store:// and intent:// links From time to time i encounter in links such as:

  android-app://com.sudaytoz.kakao.wbb/stzkakaowbb/sundaytoz

and i want to understand what is their play.google name
the previous example answer is:

  https://play.google.com/store/apps/details?id=com.sundaytoz.kakao.wbb

is it always like this? I guess i don't really get the "android-app://" prefix.

Same goes for links like:

  intent://adjust_reftag=c7L1pVanNIjjt#Intent;scheme=yandextaxi;package=ru.yandex.taxi;end

The application ID is essentially a regular Java package name that follows these 3 rules:

1.It must have at least two segments (one or more dots).
2.Each segment must start with a letter.
3.All characters must be alphanumeric or an underscore [a-zA-Z0-9_].

As you can see in your links, the URL on Google Play contains the application ID.

How many times can an app purchase be refunded on Play Store? How many times can one purchase an app and refund and continue to do so?
Wouldn't continuous refunds hurt Google ?

Paid apps/games!/in-app purchases can only be refunded once. If you buy the app again, you can't get refund
From Play Store help (see
Refunds & returns → Learn about refunds on Google Play →Google Play refund policies)

Note: You can only return an app or game for a refund once. If you buy it again you will not be able to get a refund. If a refund is issued you will lose access to the item.

(Emphasis added)

Is there a reasoning to how often and long the notification light blinks? I have a Droid X.  The green light on the front blinks when something has happened, but I've noticed that the number of blinks and their length is not consistent.

Is there some method to it?  Some code to it?  Does it reflect the event that has occurred in some way>?

Some apps will use the LED to indicate that there is a notification. For instance, the LED blinks green for me when I've received an e-mail message and blinks blue when Twitter has a message for me.

There's no consistency as to how to manage these, however. For instance Google Voice has it under Menu | More | Settings | Sync and notifications | Light, but no way to choose the color. Gmail doesn't offer any way to control it.


Read product reviews and find better alternatives by scanning barcode Is there a way to read product reviews and find alternative products/suggestions by scanning a barcode with my Galaxy Nexus? I found searchreviews, but it was not so good. If not, are there any web services to achieve this?

I use ShopSavvy Barcode Scanner to scan barcodes and check for reviews. It works with Google books and other services. You can also let it search online; it will open your browser and search the barcode.

I'm not sure about alternatives, though. But if it takes you to Amazon, Amazon can give you recommendations.


support of Android 4.1.1 Jelly Bean CM10 ROM on Samsung Galaxy Ace s5830 Is possible to update with this jelly bean version? I have updated my phone with this jelly bean version and when i am rebooting it then it is showing only samsung start screen. I don't get further screen to show my phone start desktop! Please help me. Any suggestions are welcomed!

According to the CyanogenMod Devices Overview page the Samsung Galaxy Ace is not supported by CM9 and CM10. The download page for the Galaxy Ace only has CM7 ROMs and the links for CM9 and 10 lead to their Google Plus post about not supporting first generation Snapdragon devices past the CM7 branch. That post can be seen here.

It looks like someone may have compiled a CM10 "Lite" ROM from the CM source that can be found here and someone at XDA compiled a full ROM here. If you installed either of those I would suggest rebooting into recovery and clearing data, cache, etc. and then try re-flashing the ROM. There's also a list of ROMs in XDA's development forum here.


How does WhatsApp get around Doze Almost all the posts I saw imply that WhatsApp does not use GCM. Instead, it uses two sockets to communicate using FunXMPP.

Then how is the App active on Marshmallow even in Doze mode ?

I don't remember giving the permission REQUEST_IGNORE_BATTERY_OPTIMIZATIONS to the Application. And yes, the app is not whitelisted

I don't have WhatsApp installed but I had similar question with Truacaller so I will try to explain a bit how it works and how I forced Truecaller to hibernate.

In Android there are services that can be run by actions (triggers). When some event happens ie. phone call or plugged in, this event will be send to all apps that uses Phone Call Service even these apps are hibernated. Some services are critical and cannot be closed when system goes sleep. Application can avoid being dozed by reporting to use these services. I also didn't give the permission to Truecaller but it was active all the time. I even force hibernated it with full version of Greenify (with Xposed module) but it was active anyway.

What I did with Truecaller was to install DisableService (root needed) and saw what services were used by this app. I didn't know what service I should disable so I disabled all. App of course crashed when I tried to open it. So I was repeadtly enabling some services and observing what functions were getting restored. With that I found services that made Truecaller invincible. Now Truecaller works only when I need to check unknown number.


Did ICS stop supporting clicking a number in text to dial? I used to be able to click a number inside text (email or web page) to dial it. After upgrading to ics this feature seems to have been removed. Is that so? Any way to get it back?

UPDATE: it seems to work with US phone numbers, but not ones that are used in my country (Israel). Can it be that my carrier forgot to update the pattern for recognizing numbers as phone numbers?

As @roxan seemed to be indicating, there is a legal suit against HTC in which Apple claimed a patent on this ability to convert clicking on phone numbers and email addresses into actionable links on smartphones.

This December 2011 article says:

  Apple also has civil patent infringement cases against HTC and
  Samsung. Both Asian rivals have also filed their own retaliatory
  actions to the ITC and in U.S courts

and this article indicates Apple opened four lawsuits (as of February 2012) against Samsung for patent infringement, including the ability to make phone numbers clickable.

So it looks as if other manufacturers may be rolling back this feature early, for fear of Apple's patent troll tearing down their towns and eating their goats (and your ability to click phone numbers).


Jellybean 4.2 Auto-Download and Display file I'm looking to mount a cheap 7" android on my wall to display current tasks, events and household requirements.
Does android 4.2 have a built-in tool that can download a file from a server every 5 minutes and display it on screen?
I know it must have rsync but I'm not sure about the displaying information

There's no built-in tool to do this - why would there be? - but there are several apps available depending on exactly what kind of information you want to show and how you want it displayed. For example, you could do worse than my app Showr, which is a home screen widget. You tell it the web address of an image file, or an RSS feed with images, and how often to update it, and it updates the image and displays it on your home screen. It's a free download from Google Play. My users often use it to display information like weather maps and charts, as well as more fun things like webcams, photo blogs, and logos or pictures of things or people they like.

You might also use home screen widgets for other kinds of information. For example, if the events you want to display are in a Google calendar (or can be imported into it from an iCal file or similar), then the Google calendar app can display upcoming events in a list on the home screen.

There's quite a few task list apps too, and they usually have home screen widgets and push capabilities, so if you add or complete a task from your phone, the list on the wall updates automatically. Remember the Milk is one such, which I use, but you have to pay a subscription for unlimited syncing.


Rooting and updating to Official Updates I have a S2. I want to root my phone to use the amazing apps out there Not to install custom roms. Can i still get access to the official updates from Samsung ?

I recommend using OTA RootKeeper. From the app description:

  This application makes a backup or a protected backup of your device's root.
  This device must already be rooted: OTA RootKeeper doesn't have the ability to root devices.

It allows you to temporary un-root your phone for OTA updates and then restore back root.

Before installing please check this XDA thread.


Sync Google Reminders with calendar There any way / program for synchronization Google Reminders, which use for Google Now, with calendar?

I need this because I have cloud calendar (btw this cloud on the google too :) and so uncomfortable when Google Reminders saves data only local on my device (phone and watch).

I believe that this is covered in the same way that Inbox app covered reminders. According to this document, these events should show up in your calendar. Have you updated your calendar app?


Can I install another OS on Android? I have a Samsung galaxy note 3 which has root access (I think, I mean I can access and change files in /root by the help of an installed SuperSU) and I'm wondering if I can install and .ISO from a DVD, I do have a USB DVD drive and the required adapter, I'm planning on installing Ubuntu Desktop or a version of Windows.

Thanks in advance.

Yes, you can use a custom ROM on your Android device.

You also need a custom kernel, that supports multiboot/multi-OS and you need a special Ubuntu build with ARM and hardware support. It may be hard to find but I don't think it's impossible. reference site: Asus Zenfone Blog


How do i make a new album in the HTC Photos application? I have an HTC Hero (with the Android 2.1 update). For the longest time, I've wanted to create new albums in the Photos application and can't for the life of me figure out how to do it. It has a bunch of default albums like "My Favroties" "All photos" and such. I just want to create my own albums so I can organize some pictures, like an album of all the pictures of my ridiculously cute niece. Anyone know how to do that? Or can suggest a better photo management application for Android 2.1?

It's actually quite simple just hard to figure out.

Install a file manager app (Astro, inKa File Manager)
Using a file manager app navigate to sdcard > media folder
Create a new folder

Place all your photos into that newly created folder. It may take some time but eventually the new photo album will appear inside HTC's Gallery app.


Old sim deactivated but i want to use that same number for new sim My old sim has been deactivated and most of my contacts know me by my old number.
I want some way to register my whatsapp to that old number

Phone numbers aren't tied so much to the SIM card, but to the provider via your SIM card. Your old phone number can be reassigned to another person now, so it would be unwise at best, probably illegal, to make Whatsapp use your old phone number.

In short, "your" old phone number is no longer yours.


How to synchronize birthdates from contacts with google calendar on HTC Hero? I'm aware of the fact that the standard contacts/calendar app does not support birthdates synchronization (Android issue 1211). But may be there is some third-party software which can make those synchronized for me?

Is this still a problem? I see birthdays from contacts in Calendar.

I add birthdays to my contacts in Gmail, and I subscribed to the "Contacts' birthdays and events" in Google Calendar:

Under "Other calendars" Add > Browse
Select "Interesting Calendars"
Select "Contacts' birthdays and events"

This gives me a calendar in Google Calendar with my contact's birthdays.

When I got my android (a motorola xt720 running eclair), the birthday calendar showed in the Calendar app.

You'll probably have to open the Calendar app > Menu > My Calendars. And then Menu > Add calendars. You should see Contacts' birthdays and events.


How to show Touches and Pointer Location on Screen without Developer Mode? I am trying to use my phone as controller and my 42 TV as display. Chromecast is casting the thing.

I have tried Show Touches and Show pointer location as described here in Developer options. However, I do not want to keep Developer options active all the time. Also, some of the features fail too often, causing epileptic continuous blinking in different colours.
I do not have any other option (etc Show GPU view updates) on in Developer Options.

Phone: Oneplus 2
OS: CyanogenMod 13

No support for this in Android 6-7 by default without the developer mode.


Driving Mode isn't working as expected on Samsung Galaxy SII I have this Samsung Galaxy SII, GT-I9100T, with Android version 2.3.3.

When placed in Dock with my car, the following happens

Whenever a call is incoming, the phone would read me the calling number, even if he's found in my contacts.
Whenever a message is incoming, the phone will sometimes read me their phone number, even if they're found in my contacts.

What can cause this? I've checked the configuration and found nothing helpful, Google wasn't much of a help either.

It could be possible that the contacts have been entered incorrectly, or it could be a bug with your version of the car mode app.

Please ensure that none of your contacts are duplicated, and also please ensure that the numbers are correct (you may need to add/remove the country code).

Another reason could be due to the country code being displayed when the SMS/Call is incoming, but not being in the contact.


Youtube not playing in Wifi I have this real strange problem that youtube is not playing on my Onda Tablet (dark screen and "problem while playing"), when I am in my home wifi. When I use my mobile as a hotspot and connect my tablet to it (also via wifi) it's working.
I use several android devices and the Onda Tablet is the only one, which does not play Youtube.
Other Video Players work without problems. This also happens, when I browse to m.youtube.com in a browser on the tablet.
Here's what I already tried:

Clean Cache and data of youtube app
reinstall youtube app
manually downgrade youtube app
changed DNS of the tablet to 8.8.8.8
Factory reset the tablet
Reset my router
My only guess is a misconfiguration in the wifi options of the tablet but I could not find one.

My Tablet:
Onda air v989 running Android 4.4.4
Any help would be much appreciated.
Thank you!

So, I came across the solution for my very specific problem:

My tablet seems to have a problem concerning youtube and IPv6. It's probably some flaw in the firmware.
After speaking to my internet provider I am now constantly leasing an IPv4 Adress and youtube is working just fine.

If you have similiar problems you should definitly try this out!


Change calendar location viewer When I put in a location for an event in the Google Calendar on my Nexus 4, and then select it later it opens up in Google Earth which I do not want to happen.

How can I change it to open in Google Maps, so I can use the location for directions?

I have looked under Settings > calendar but there was nothing under the default open header.

Am I looking in right place?

I'm prompted to select what I want to use to open the link, so it looks like you've set a default action for that Intent.

You'll need to go to Settings > Apps > (downloaded or all) > Earth > Clear defaults. Next time you click a location in the calendar it should prompt you for what you want to use to open it.

Unfortunately, this resets all the defaults for Google Earth.


What is a decent speed for a card that can be used as internal storage in marshmallow? Marshmallow allows sd cards to be used as internal storage.

I would like to know what is the benchmark for the cards that can be used seamlessly with Marshmallow as internal storage.

It would be good if someone can the technical details of the cards to look at before buying cards for marshmallow.

My SanDisc Ultra was according to Marshmallow not fast enough ;( - but worked. I couldnt find anything on the Definition of the Speed for Marshmallow to swallow those SDs without an notification.
But I assume that all are not fast enough and you will get notifications nonetheless:
Here are Classifications of Speed:
For Samsung Flagship (S6 e.g.)
UFC 2.0 = 100mb/s
emmc    = 90mb/s (most of the phones have this)
SD Cards:
UHS3 30mb/s
UHS1 10mb /s
class 10 10mb/s
class 6 6mb/s
(those Speeds (obviously) are depending on your phones Controller)

I feel like that as Long as the SD Card Speed is smaller as the built in Speeds - your will get those error/info notifications.
But I could get it to run with class 10 (no Problems) - Streaming movies / Music was no Problem

Do you want to use the internal mode? (on what phone/purpose?)


What am I left with after rooting? I have a stock Nexus 5 and I want to root the device so I can tether it with a laptop.  I see instructions on doing this, and it all looks plenty easy, I am just concerned with what's going on and the mention of images.

In the end, I just want to be left with my same stock android, just with the ability to do some things with elevated privileges.

After the root process is the phone executing any other code or was that code just a temporary thing as part of the process to root the device?

Also, if/when a new Android OS update comes along, will I still receive it like I normally would?

After rooting you will still be left with stock android just with elevated privileges as you've said.

Remember, your data will be wiped, so I'd recommend doing a backup first!

If a new OS update comes along you will not be able to install via the normal Over the Air method, but you can still download the update manually and flash it via TWRP.

If you take a look here you can see all the other things you gain by rooting.


Max USB Webcam Resolution and Frame rate What are the maximum resolutions and frame rates for USB camera that a Android device supports. I read that the standard is called as UVC (Universal Video Class).
Is this support dependant on the Android version? Would the type of connector make a difference USB-C vs micro USB?
The best resource I found was External USB Cameras
On that page its mentioned,

With support for webcams, devices can be used in lightweight use cases
such as video chatting and photo kiosks. This feature doesn't replace
typical internal camera HALs on Android phones and isn't designed to
support performance-intensive, complex tasks involving high-resolution
and high-speed streaming, AR, and manual ISP/sensor/lens control.

Also a list is given at the end of the articles regarding frame rates and resolutions as if they were extracted from some code so I'm not sure what they are and whether to consider them as definitive.
<!-- List of maximum fps for various output sizes -->
<!-- Any image size smaller than the size listed in Limit row will report
    fps (as minimum frame duration) up to the fpsBound value. -->
<FpsList>
    <!-- width/height must be increasing, fpsBound must be decreasing-->
    <Limit width="640" height="480" fpsBound="30.0"/>
    <Limit width="1280" height="720" fpsBound="15.0"/>
    <Limit width="1920" height="1080" fpsBound="10.0"/>
    <!-- image size larger than the last entry will not be supported-->
</FpsList>

It depends on the external camera provider specs.

From External USB Cameras  |  Android Open Source Project

The USB camera HAL process is part of the external camera provider that listens to USB device availability and enumerates external camera devices accordingly.

Webcams generally support USB video class (UVC)
drivers and on Linux, the standard Video4Linux (V4L)
driver is used to control UVC cameras.

Probably, what's quoted is typical or frequently found values but if you want specific information you would need to dig into the code of the device + camera provider.
As asked in the comments maximum limits can be gleaned from

the camera specs and codes

format used  (for example UVC format itself has multiple variations - see linked wiki above)

but whether the device uses full capability or not is the important point.
You would find tons of rooted means and Magisk modules that improve the camera performance with the same device and camera - it's only possible because ROM didn't build in those features.


Does Android auto-switch between SIMs for data on dual-SIM phones when one of the SIMs has poor reception? If you're using the internet on the phone, does Android auto-switch between SIMs on dual-SIM phones when one of the SIMs has poor reception?

https://honestmobile.co.uk/ seem to think some phones do and they advise turning it off so as not to interfere with their own app that selects from the providers they MVNO on top of.

It would be a handy alternative to Speedify VPN to bond separate mobiles, if the SIMs in those could be put in a dual SIM phone.

(By the way, I don't have an financial interest or otherwise in Honest Mobile, nor Speedify).

Thank you.

If you're using the internet on the phone, does Android auto-switch between SIMs on dual-SIM phones when one of the SIMs has poor reception?

No. Android doesn't offer such provisions. Pixel 3a line is dual Sim and if Android has this provision, it would have been incorporated in these phones.
It is most likely referring to Dual SIM Dual Active devices where both the Sims simultaneously can be active be it voice or data. As an example you could be talking on SIM1 and yet receive a call on SIM2 which will be put on hold or you could attend that and put the first SIM call on hold (Pixel 3a have this).
(This is in contrast to Dual SIM Dual Standby, wherein if SIM1 is in use, SIM2 becomes inactive and vice - versa. Such phones are cheaper)
Edit: If you are referring to Smart Signal, the FAQ clearly says it doesn't choose the best signal (as your question implies) but merely switches between two networks

Does Smart Signal automatically choose the network with the best signal?
No, with Smart Signal you’ll automatically switch to EE or O2 if you lose signal on Honest Mobile. On some phones you can also manually select which network you want to be on.


How to print a webpage from my Android phone? Possible Duplicate:
  Is there any way to print directly from the phone?

Assuming a modern (compatible) mobile printer, is it possible to print a webpage or a PDF document directly and natively from the phone?

I've heard of PrintShare, and saw this question, I'm asking if it can be done natively, without the use of another application.

If that's not possible, is there some sort of API I can use to achieve it? Assuming I write my own application.

There is no known API available for any form of printing support within the Android system itself.


Using a 128GB MicroSD card with a device with 64GB maximum? Samsung's specs for my Galaxy S3 say:

128GB MicroSD cards probably didn't exist when this phone was made.

If I insert a 128GB MicroSD card, will the card:

"not function at all"

or will it:

"work fine" but only let me use 64GB?

It will work fine and you'll have access to the entire storage space.

It's usually just a recommendation for a better user experience in my opinion, If I used the recommended maximum SD Card size on my device It'd be able to load all my photos, music, app data  without any serious delay, however if I put a huge SD Card in my device it could take hours to load 128gb worth of photos, Therefore it's necessary to recommended a maximum size for the best user experience.

You will need to format your SD Card to Fat32 on a PC if it's not already formatted.

A good free software for this on Windows would be

Reduce space taken by Outlook Outlook is eating up space in my Samsung J7 prime. I am currently working with something between 100Mb and zero free space.
If I free up some space, it seems Outlook increases its occupied space.
Is there any way to tell Outlook which folders I want it to sync?
Or any other way to limit (e.g., from the OS) the space it takes?

I know this may not be an exact answer, but I ultimately switched to Android Firefox web browser (or your favorite browser), with desktop homepage link to outlook.offfice.com and... it behaves perfectly. That is, assuming your email account is served there...
MS actually did pretty good job with their mobile web page rendering and functionality, and so far I do not miss any functionality (email, calendar...) from my bloated Outlook for Android app (800MB unmovable local storage!).
Hope this helps somebody.


How can I remotely start an application on my android phone? I have an older phone (Android 2.x) that I am not using as a phone.  I am using it in a carboard projector.

I would like to be able to use my desktop computer to instruct it to play a youtube video.  I tried Airdroid, but it doesn't seem to have this functionality.

Any ideas?

You can try AndroidLost app, the premium version of which has this facility.


My phone is charging my MacBook over USB C, and not showing up as an adb device. Is there a fix? Sorry in advance if this is a duplicate, I couldn't find a solution to this exact problem posted anywhere.
I'm using Unity on macOS and I am trying to build for Android. I'm running into an issue where my development phone (it's a Galaxy A5 2017) will start charging my MacBook when I plug it in and will not show up as an adb device.
What I've done so far is:

Enable USB debugging on my phone
Install android-sdk and android-platform-tools through homebrew
Install openjdk@8 through homebrew (this resolved an issue where the sdk required java 8)
Attempt to switch the USB mode on the phone from 'Charge connected device' to 'Transfer files'
Switch USB ports

Trying to switch USB modes on the phone does not seem to work, it will close the dialog when selecting 'Transfer files' but when I check in the notification shade it will still be set to 'Charge connected device'. I also tried checking if the phone showed up over adb, but unfortunately adb devices returns an empty list.
Potentially useful information: I have built this exact Unity project to this exact phone successfully from my Windows desktop with this USB C to C cable, but I need to be able to do this from my MacBook.
I am using:

Unity 2021.1.4f
macOS Big Sur 11.4
Android 8.0.0

My question is, how can I prevent my phone from trying to charge the Mac? How can I get it to show up as an adb device so I can build to it from Unity?
Edit: alecxs suggested another question as a possible solution but this did not work for me either. In USB debugging, the USB mode is still set to MTP file transfer when this issue occurs. Changing it to something else and back unfortunately does not resolve the issue.
Edit 2: looks like this is a problem with macOS. I came across this article that mentioned for Samsung phones you need to use Smart Switch. I downloaded it for macOS, but it warned me that until further notice they do not support Big Sur as their system extension has not been approved. There is a temporary workaround mentioned in the warning here, but it is a bit involved, requiring you to disable SIP. For now this seems like the only solution. Since I know the root of the issue, I will mark this question as solved.

I believe I've found the issue, I added an edit to the original post. Looks like this is a problem with macOS. I came across this article that mentioned for Samsung phones you need to use Smart Switch. I downloaded it for macOS, but it warned me that until further notice they do not support Big Sur as their system extension has not been approved. There is a temporary workaround mentioned in the warning that can be found here, but it is a bit involved, requiring you to disable SIP. For now this seems like the only solution until Apple approves the extension.


Avoid reload when activating browser When I start my mobile browser it is usually to browse some other place than what it currently shows, but both firefox and the default browser insist on reloading what random page they hold before I'm able to proceed.

Is there any way to avoid the reload in these browsers?

Edit

The answer from NDgeek works as a workaround for the default browser, but not for Firefox as it requires at least one tab to exist.

After poking around a bit with the two applications, a similar workaround occurred to me, which is to point the active tab to a light-weight page before exiting, e.g. about:blank or about:home, now when the browser is activated it is available quicker.

I'll use the above workaround but as it requires extra work from me before I move away from the browser, I would prefer a more automatic solution.

The only way I know of to prevent this when opening the browser directly is to close all tabs before exiting the browser. If you open a link from another app, you should be able to avoid this as well.

Does a factory reset on a Galaxy Nexus wipe the virtual sd card directory? I'm looking into wiping my Galaxy Nexus, but I need to know whether or not a factory reset will also wipe the virtual SD card on the phone.  If it does, is there an alternative way to wipe without affecting the virtual SD card?

I'm running stock JellyBean 4.1.1, rooted.

A factory reset does indeed reset the virtual SD card on a Galaxy Nexus.

Okay, initially it appeared as if it wiped the virtual SD card, but it did not. After the media scanner did its magic, everything on the sd card (mostly) still remained there.

I did a factory reset by going to Android's Settings, then Backup & Reset, and did the factory restore option. I did not wipe the device from recovery.


How do I run an application on my phone from my PC? I have a phone with a touch-screen malfunction, I want to run applications on it from my computer, connected by USB. Is that possible?

I've tried applications like http://mymobiler.com, but that has failed me (I can see the screen, it's not responsive).

Sadly, I have ADB turned off, so I cannot use applications like the android screencast, or DroidExplorer.

LogMeIn Ignition may work for what you want to do. It really remote controls the pc but to truly run a PC app it would have to be on a PC.


screen is broke at the bottom I had just bought  zte  Android phone. An I was short on cash so I didnt get the insurance an went to leave an dropped it. I hadn't even  activate activate it yet. Is there anyway I can use for keyboard just till I get passed set up.

Sorry to hear about that. Could you please refine your mobile model? If it supports OTG, you can use OTG Cable(would cost you around $1) to connect an external mouse or a keyboard to mobile to complete the setup.


How can I see what IP address my android phone has? I would like to know what IP-address my Android phone has. E.g. if I use my phone over WiFi, how can I get the local IP-address that is assigned to my phone?

The easy way is to go to your WiFi Settings, and hit Menu > Advanced. It'll show up there, or you can set it to a static IP if you want.

The cool way is to dial *#*#4636#*#* to open the Testing menu. Then click WiFi information, then WiFi Status.

Can a screen-locked Android phone be rooted? By locked I mean a phone that has been locked with a standard PIN code, password or pattern.

I'm not meaning to break into somebody's phone, merely wondering to what extent applying any of the standard screen lock methods to my phone would protect my data in case of theft.

In case a locked phone can easily be rooted, I assume the lock can then also be bypassed, and locking the phone is then really of little value for protection (since rooting techniques are common knowledge these days), and I would then have to consider other protection mechanism, such as encryption.

Please keep your answer concise, and don't give general security advice. I just want to know if there are known (widespread) methods to root locked Android devices.

Note this question is with regard to Android phones with factory default settings (i.e. no developer options, USB debugging enabled).

I'm specifically interested in Nexus devices running Android 4.4 KitKat.

Short answer: no.

Long answer: not usually, but there some exceptions.

In general, to root the phone, you first have to unlock the bootloader. This wipes the internal storage, keeping your data safe. (It doesn't usually wipe the SD card, but you have to assume an attacker will just remove the SD card if he wants to read it). You'd almost think it was designed this way!

You can easily get past a screen lock using ADB, but you've already specified that that's disabled. Even if USB debugging is enabled on the phone, newer Android versions have a "confirm the debugging key" prompt when you use ADB from a new PC, which requires the attacker to unlock the screen anyway.

Some phones have low-level security vulnerabilities that aren't part of Android. For example, you used to be able to root any exynos4 device (such as the Samsung Galaxy S3) by running an app that abused the camera interface to exploit the way the camera driver works. (This flaw has now been fixed in OTA updates.) In this particular case, you'd need to install a special app of your choice onto the phone and run it to exploit the vulnerability. It's likely that any future errors like this will also need the attacker to run a special app, so can't be used on a locked phone with USB disabled, but it's conceivable that some flaw might be added that could be exploited from the lock screen (perhaps using MTP or USB-OTG).

The last exception is, of course, if the bootloader is already unlocked. In this case, the attacker can flash anything he likes to the system. He wouldn't even need to root the phone: he could simply disable the lock screen and reboot the phone to get to the home screen. Some users think that bootloader locking is just to make things harder for users, but it's an important part of Android's security mechanism.


Android browser not able to access router's settings page I can access the router's settings page via 192.168.1.1 with my PC but not with my android device. What can be the reason?
My device: Android gingerbread with stock browser. Also tried with other browsers. e.g. Opera Mini, etc..
EDIT 1:
My device is connected in the same network via wi-fi.
The IP's of different devices on the network are:

Home PC: 192.168.1.2
Router: 192.168.1.1
Android Device: 192.168.1.3

EDIT 2: Screen-shots

Pinging stackoverflow: IP is not static. Router assigns dynamically. Right now, the device is assigned 192.1

Browser not able to load router's page:

I got a similar behavior with my last Router I had (it was a DLINK Router), there was an option "do not Display Router Configuration Page for WiFi Devices".

This is just a possible option I can imagine now.

Opera Mini would generally not work, since it's traffic is routed over the Operas Servers to compress the Webtraffic that is been sent to your smartphone.

Quote:

  Unlike straightforward web browsers, Opera Mini fetches all content through a proxy server and reformats web pages into a format more suitable for small screens.[33] A page is compressed, then delivered to the phone in a markup language called OBML (Opera Binary Markup Language), which Opera Mini can interpret.[34] The data compression makes transfer time about two to three times faster,[18] and the pre-processing improves the display of web pages not designed for small screens.[35]

Source : http://en.wikipedia.org/wiki/Opera_Mini

And since Opera isn't able to route into your private network it would not work.


Samsung build number and rooting SM-G900P I would like to root my Boost Mobile  Samsung S5. I've read up enough to know that I need to be 100% about the model and software build version before proceeding with the root.

My provider: Boost/Sprint
Model: SM-G900P
Build: mmb29m.g900pvpu3cpg1
Android 6.0.1

I've looked around and found confirmations for this build with one difference, the builds confirmed don't have the "1" at the end of the build I.D.

Can anyone explain the significance of the 1 at the end of my build?

Also will I need to reactivate my service if I root?

Reference

  Can anyone explain the significance of the 1 at the end

No

Google Now "Shazam this song" not working I'm trying to use this feature
https://support.shazam.com/hc/en-us/articles/205024298--Ok-Google-Shazam-this-song-

But when I try it just google searches "Shazam this song" like any other unrecognized phrase. I also tried "What's this song" and it said "Action not supported in your country"

I'm in Canada and have a Samsung Galaxy S5 with Android 6.0.1. I have Shazam installed, and reinstalling it didn't fix it.

Try holding your home button down for 3 seconds. When Google Assistant appears, ask your question. Same thing happened to me with sluggish responses from google now requests after the  6.0.1 update rolled out. Google Assistant taking over for Google Now going forward.


How to receive a notification for each new message in a conversation? If I have a conversation with unread messages, I get no new notifications for new messages in the conversation. Is there a way to get these notifications?

On Android, go to settings, then bundle notifications. There should be a little bell icon next to each category that you want notifications about. This took me forever to realize how to fix, but much better now! Good luck.


Moto Droid - Screen Going Crazy / SD Card Contents So about an hour ago I was texting and noticed that when I would try to hit certain letters using the on-screen keyboard that it would think I pressed the keys to the left or right of a certain area.  It seemed like a deadspot to me and already I was disappointed but it wasn't a giant issue as I could just use the hardware keyboard til I got it fixed.  Now, however, after ~1 minute of being booted up, the screen just starts going crazy, loading random applications, zooming in on stuff, flickering left and right like I was swiping it.  I was wondering if anyone had any experience as to what can cause this (other than hardware failure) and if you think doing a factory reset will help at all (assuming I can get through the options fast enough before the screen goes nuts).

Also, before trying a factory reset, I was wondering what all is stored on the SD card by default.  I'm not really worried about apps (I'll just re-download them) or contacts (synced with Google I believe), but more media (pictures / videos [both that I took and downloaded] / music).  Now common sense would suggest that media items would all be stored on the SD card, but I know from experience not to assume things like this.  If you could fill me in it would be much appreciated.

Pictures, videos, downloads, and music are all stored on the SD card by default. You can get at them by popping your SD card into any card reader. (probably have to get an adapter)

App settings are stored on the phone. But if those apps support google's backup service those settings will be restored on your new phone.


Instant read/write sync with iCal calendars avoiding the use of google calendars After using iphone/mac for a lot of time, I got a new android phone. I use on my macbook only ical calendars, and wonder what is the best app for syncing ical with my android phone. I have read something that you can sync first ical to google calendars and so on, but I Wonder if we can avoid this workaround.

If you want to sync with a calendar using the iCal format, there are apps available on the Playstore doing exactly that, like iCalSync or iCalSync2, and there's also The Missing Sync (requiring a paid desktop component) or SyncMate (specifically tailored for Mac, but again requiring a desktop component).

Most likely there are plenty of additional alternatives (take a look e.g. at these search results). Unfortunately, I don't know of any native solution not involving 3rd party tools.


How to have microG works on Havoc OS? Long story short, microG is supposed to take advantage of signature spoofing in order to do his magic. But I couldn't make this happen.

Context :

I just did a clean install of Havoc OS (Android Pie) on my Oneplus 3 using this thread.

This distro is supposed to natively support Signature Spoofing, as it claims in its features list (twice). And migroG is officially supported. But there's no support provided on SourceForge (official website for Havoc OS) and the way to contact the dev is Telegram (which I don't use).

What I've tried ?

There is a switch available in the Settings app, and according to the terminal, it's working : settings get global allow_signature_fake returns 1 or 0, depending on that switch.

However, when trying to check with microG or with this checker I get a negative answer.
You can see it on these screenshots :

Over the 600 pages of the official thread, I saw other people having issue with this but noone really have a working solution.

Some said they used a Magisk module called NanoDroid, but in its today's version, this one detects that the distro already allow it and do nothing.
Plus, I read this override on distro natively supporting it is not recommended anyway.

According to this thread :

  LineageOS for microG since December updates refuses sigspoof to work when the permission is not defined in privapp-permissions, this is now the case (on all ROMs with native sigspoof support)

As Havoc OS is based on LineageOS, I've tried that too.
I've then installed a magisk module called [Terminal] App Systemizer and use it to swap both apps (Checker and microG) to /system/priv-app.

Then after reboot I've got some progress : Signature Spoofing Checker still says "Disabled", but microG show one more checkbox filled (System grants signature spoofing permission). See the screenshot :

Now I'm stuck and have no clue were to go next. Any idea ?

Havoc Os v2.2 is out, (see on xda thread for Oneplus 3/3T)

This version correct the problem and everything works as expected now.


Do HTC widgets not work with ADWLauncher? I've just installed ADW.launcher, which is a lot cleaner than the original HTC Sense homescreen, but I can't seem to get my Clock/Weather widget back. It's not appearing in the list of widgets.

Is it just me, or do none of the HTC widgets work with ADW Launcher, or is it that the HTC widgets will only work with the HTC home screen?

Alternatively, is there a decent clock app that displays digital time, and maybe weather too?

HTC Sense widgets do indeed only work with the Sense homescreen. There are knock-offs, but these are usually pulled off the market by HTC very quickly. Beautiful Widgets comes quite close though.


Nexus 5 not getting net data even though its having hspa+ range I tried rebooting my phone, reset to default on APN , safe mode but nothing seems to work.I still dont get internet on my phone.I'm from India and connection  is docomo.

Any help would be greatly appreciated.

Go to

  Settings > More > Mobile Networks > "Use only 2G Networks"

Make sure the above option is unchecked and you've correctly activated a proper 3G plan. Also, don't forget to configure the APN for using the internet.


MetroPCS ZTE cannot connect to the carrier data network I recently had to factory reset my MetroPCS ZTE phone. Now when I put the SIM card in from my Huawei it won't connect to the carrier data network, it only works on WiFi.

Try going into Settings -> Wireless & Networks -> Mobile Networks -> APNs and make sure the MetroPCS APN is selected.

Here is what mine looks like (I am on t-mobile, which is why I have that selected). Your list may be different.

If this doesn't work, give MetroPCS a call and have them re-add the device to the network on their end.


Contact account association with non-HTC phones? My HTC legend give me the ability to associate my contacts' various accounts in the People application (ie. email, Facebook, Twitter...). Is this a HTC only feature? If it is, is there an alternative for non-HTC phones?

The people application itself is an HTC exclusive, but merged contacts from multiple sources (GMail, Exchange, Twitter, Facebook, SIM, carrier phonebook, etc) is a standard Android feature for 2.x (maybe earlier). By default the system tries to intelligently merge identically named contacts, but you can manually add/remove contacts from the merged identities.


Mi 9 (M1902F1G) running MIUI 10.2.15.0 issue with fitness trackers I'm seeing issues with my new phone that it's not keeping the GPS enabled when fitness trackers are running.

E.g. a bike ride consists of a straight line between the start and end location.

I've tried Ghostracer and Strava and both seems to be having the same issues.

I've tried switching the "Battery Saver" setting for both apps to "No restrictions" (they were both previously on "Battery saver (recommended)"), but that makes no difference.

Anyone else with the same issue or ideally a fix?

Problem seems to be with the "Use Adaptive Battery" feature.

I'd guess it's not clever enough to differentiate between an app not being used very often, and an app being used after being recently installed.


Hide games in "apps" in Play Store? I'm hoping for a way for Play store to stop promoting games to me all over the place. I don't mind them listed in the Games category, but I can't stand to have them in the Apps category. Any way to do this?

Using play store ver. 5.3.6

The playstore app will not show any games if you open it with this link:
https://play.google.com/store/apps/category/APPLICATION

I hope that it becomes accessible from inside the app one day.

Removing verification scripts from a stock ROM I'm not really familiar with Android development so I'm not sure how to go about this, sorry if those questions are basic.

I have successfully flashed a TWRP recovery on my MTK6797 phone (UMI Z Pro) and I can enter it but somehow managed to soft brick it (the ROM itself doesn't boot, - hangs on the boot screen).
So I'd like to install the stock ROM again but keep TWRP recovery since I was planning to tweak the ROM or even perhaps build a custom ROM for this phone since there are none available and probably won't be any in the future.

The problem is that the stock ROM contains some verification scripts, here's a quote from their official forum:

  You need the original boot, recovery and system image on your phone
  since the update script checks their integrity before running. As a
  conclusion, if you have a custom recovery on your phone and/or ever
  rooted it, you cannot update it via FOTA but the only way is flashing
  with SPFT.

How would I go about removing those scripts from the stock ROM? Or does anyone know of another solution to this - TWRP recovery + stock ROM on this phone.
Thanks in advance.

One question first your phones a umiz pro and the twrp is based on umi z.V3.xxx.xxxxx  from Google it appears that there is a base and pro model am I correct
If so then I think from your post it sounds like u flashed the base model recovery on. A pro model I have done this on a homtom ht7 I really messed it up but I think that is your problum


Transferring files applications via USB on Mac I have Nexus 5 and I'm using the Android File Transfer as explained on Google's official support: Transfer files between your computer and Android device.

However, after either copying zip archives or creating new folders in the file transfer window with my Nexus 5 connected via USB, I do not see the changes reflected on the device.

What am I missing?

Assume you are using the android File transfer program from http://www.android.com/filetransfer as that is the best way to transfer files on OSX.

If you just drag files into that directory it opens by default, the files might not show. On the "Android File Transfer" App choose the "Download" directory which is the best place to store a file, then drag files into that directory. This directory is accessible by all programs that have access to the internal storage.


whatsapp bluetooth call gets disrupted by 2nd incoming call In Android 10, while talking to a person on Whatsapp using bluetooth headphones, I receive a standard call on the phone, and two bad things happen:

the sound of incoming call is bothering me for too long and too loud, as if it does not realise I'm using bluetooth headphones,
once the incoming call is not answered, I lose bluetooth connection in Whatsapp, namely it goes back to default phone speaker/mic.

(This situation could also be e.g. Whatsapp/Signal, or even perphaps the ongoing call being disrupted by the incoming one: in this case where is the priority set?)

Is this a bug of my phone/ROM, or is it standard?
Is there a way to have a better default behaviour, perhaps

only hear a low sound for incoming 2nd call while on bluetooth,
not get bluetooth disrupted and having to set it back by hand

in the Android options?

Yes it is WhatsApp bug.
You can click on Bluetooth icon to reconnect to your headphone again.
Hope this helps till it is fixed.


Stopping ongoing app updates How do I force an abort on ongoing app updates happening on my Sony Xperia Aqua Android mobile? It is slowing down all other processes. My cell is setup to do updates when it finds a wifi connection, so I can turn wifi off, but I need it for the other things. Wish there was a way I could put the update downloads on hold and then resume after I'm done using the wifi.

Few solutions:

Open Google Play Store. Goto Settings -> Auto-update apps, then select "Don't auto-update apps". (But Google Play Services and Google Play Store will be updated regardless of this settings).
You can install a firewall and block Google Play Services, Download, Download Manager and Google Play Store to block updates. Unblock them when you need to update apps.


Install apps to SD card in android 4.4.2 I made the sd card as the default install location in my phone settings but this didn't take effect, then i run adb commands to force the phone to have default install location as external using these 2 commands:

adb shell pm set-install-location 2
adb shell pm get-install-location

The output says 2[external] but i verified by installing new apps they get directly to insternal storage.
I was hoping to take advantage of this method to make possible apps can write in sd card bypassing android limitation. So do you know why this commands didn't affect the system ? is there  an equivalent command to do this ?
Thank you

Some apps, stated in their manifest files, cannot be installed to external storage (SD card). That setting will not affect those apps. You should try some other apps for verification.


How to assign my home button function to a custom launcher? I installed Apex Launcher on my S3. It takes some configuring before it is useful, so I didn't assign it to the default action of my home key. I then did accidently set the default action to use the standard launcher.

I can't find any way to now set the Apex shell/launcher/what ever it is to be the default when you press home.

Any ideas how to change my home button function?

Go to Settings > Apps > Click on the "All" tab then find your current launcher (the one that is default now) in the list. In the App Info page you should have the option to "clear defaults". Click this and the next time you hit the home button you will have the option to select a different launcher.


How to choose which joined contact to use for contact image? Okay, I'm running a Galaxy S III with the TouchWiz ROM.

I knew how to do this in AOSP ROMs, but cannot find it in the Samsung people app.

If I have an aggregate contact with numerous joined contacts, and more than one of the joined contacts have photos, how do I specify which joined contact's photo should be the photo for the master/aggregate contact?

Okay; I finally figured this out!

Go to the people app
Click on a contact to see the contact detail
Bring up the menu
Click Mark as default
Choose default picture, email, phone, etc.


Ringing volume is reduced after after updating Moto G2 to Android Lollipop After updating my Moto G2 to Lollipop 5.0, the ringing volume of my phone is reduced. Can anyone help me with a fix?

I suggest you to perform clear cache on your device. This steps will remove any temporary files that may be causing the problem, but will not delete your files or settings.

With the phone powered off, press and hold the Volume Down + Power button at the same time and release after two sec.
Press the Volume Down button twice to highlight "Recovery mode"
Press the Volume Up button to restart into Recovery mode.
You'll see an image of an Android robot with a red exclamation mark and the words "No command."
Hold the Power button, do not release it, press the Volume up button and release it (hold on the Power + Volume Up button and release).
Use the volume buttons to scroll to "Wipe cache partition" and press the Power button to select it.
"Reboot system now" will be highlighted, press the Power button to select it.


import contacts from sim to phone only I have to set up an android phone (Orange Boston, Android 2.1-update1) for a colleague.
I added two accounts, one gmail and one exchange, both only used for mail & calendar.

Now my colleague has several contacts on the sim card that he wants to import onto the phone, and the phone only.
But when I click "Import from SIM" in the contacts app I have to choose an account (gmail or roadsync (exchange app)).
I do not want them to sync to anything, just be on the phone.

I found several guides that showed that there should be a "phone only, unsynched" option, but I don't have that.

What can I do to import the contacts phone only?

In the contacts menu do you have a menu item called accounts? It should show which accounts are synched up and also have the option to not sync to any account. You could turn sync to accounts off here and may then be able to import contacts to phone only.

Alternatively you could make sure the phone is not connected to the internet (wifi or data), import the contacts into one of the accounts, then go into settings and switch sync contacts off for both the accounts available.


What limits a mobile phone to be upgraded to new Android version? What is the main reason that you can't upgrade your phone to new Android version?

Is it the lack of drivers, or simply hardware limitation? Are there other aspects?

Somebody needs to write and test the drivers and core apps. That's all.

Most applications that are written for Dalvik (i.e. most apk programs) are pretty portable across different Android versions, but not so much for core programs that were written in C, the Linux kernels and drivers, and the Dalvik VM itself. At the very least, these programs need to be recompiled; occasionally, the new Android version may require new capabilities from the drivers, and someone will need to write the code for them.

Additionally, for official releases, manufacturers and carriers often adds value-added customizations; these customizations need to be ported, tested, and often debugged against the new framework. In deciding whether to write upgrades, manufacturers (and to certain extent, carriers) faces a dilemma, they make better profit by selling to you a new device instead of writing upgrades for free, but poor upgrade history will put off customers as well; so they will often drop support for older phones and only write one or two version upgrades at most.

Hardware limitation has never been a problem for upgrades. While it's certainly true that certain new features might have a much higher hardware demand than older phones can conveniently handle (e.g. Live Wallpapers), these features are usually either disabled or left to give sub-optimal experience.

Other limitation is space limitation. Some phones have very small internal memory, and Android tends to get larger for every upgrade. To port newer versions for these phones, some sacrifices has to be made; whole libraries may be left out (e.g. who needs the NFC on a G1?). These modifications needs to be written and tested.


Google+ Auto Backup failed When looking at my photos in the Google+ app, at the bottom is a footer that says "Backup failed" with a retry button. The backup still fails when I click Retry.

Is there a way to find out why Auto Backup is failing so I can correct the problem?

Try deleting Google+ data/cache, then start Google+ app. It will log you in and then you can choose Auto Backup setting. You can then go to Sync settings, untick "Sync Google+ Auto Backup" and then tick it again. Seems to work for me. You can also go to the Google+ app settings and get it to upload all your photos/videos to start the sync.


Battery Stats Are Vastly Incorrect After updating to 6.0.1 (MMB29K) from 6.0.0 (MRA58R) I have come to face a very odd and never seen before issue. My battery stats are wildly wrong. My stats show 4k% or higher and no battery stat monitor, such as the system battery monitor or GSAM for example can see anything correctly.

Here is an image of what the battery stat shows:

Here is the power manager:

Has anyone encountered this issue and if so what's causing this? I have not found anything so far that would explain it. Although I have not yet had a chance to fully comb the source code of the latest release, I don't suspect they would release it with such a glaring issue, so I am wondering how it has come to be.

Some FYI, Its a Nexus 6 device, fully rooted and not that its relevant but also fully encrypted. Anything else you wish to know, let me know. The apps and configurations have been the same on this device (+/- occasional test app that is usually removed within a day or so) since its stock 5.0 OS (which was unlocked and rooted immediately upon receipt).

UPDATE: 12/20/15

I want to begin with many thanks to @beeshyams to offering assistance and providing possibilities to consider. Although the problem was not entirely covered by our discussion, I did figure out what the issue was because of the decision we made to reflash the boot.img and that revealed the problem. Short version, reflashed the stock 6.0.1 boot.img and it resolved the issue. Long version, read below:

TL/DR/RL

The systemless method by which the boot is being done beginning with M (6.0) was to use the SuperSU zip update to root the system without actually modifying the system partition, making for a potentially cleaner or if you will less hacky way of getting root than in the past using the system exploit. Feel free to follow the process by @chainfire here: [WIP][2015.12.20] Android 6.0 Marshmallow [v2.64] but simply put it would use a modified boot.img and a special version of the SuperSU and achieve the root. However as the project gained momentum and new methodology was tested, it was decided in favor of abandoning the use of the modified boot.img and allowing the improved SuperSU binary to handle the internally required modifications. I had forgotten to change the batch file I use to automate the process to remove the patching of the modified boot on top of the stock boot and that's in simplified term what caused the issue. I reverted the boot to the stock and applied the SuperSu binary again to modify the stock properly and it fixed the issue. Thank you for everyone's attention and I hope that this will help others in some way.

I would start by holding all three physical buttons for a full 3 minutes (phone switched off) to fix battery logic problem. This resets the battery logic on some phones and how the battery talks to the software to let it know how much power it has and other parameters. Service center may be able to help you with exact procedure for your phone (please share their recommendation so that can help others)

Few possibilities if above didn't help:

Battery houses the chip that communicates state of battery to device including charge levels, temperature etc. That could be bad, though your phone is new, being a defective piece. Can be checked by replacing battery
Fuel Gauge drivers in OS corrupted. After backing up data,reflash stock to rule out this possibility. Also eliminates rogue app possibility, though app mischief not likely on your case
Problem with hardware (Fuel Gauge chip). Unlikely but possible

Edit

Further to our discussion, saw this on Nexus forum, which sends to have worked for most, though none reported your problem https://productforums.google.com/forum/m/#!topic/nexus/D7er7nMbzHI

  1.Power off your phone.
  2"Press and hold the Power and Volume Down buttons. This will put the phone in fastboot.
  3.Use the Volume buttons to scroll through the menu until you see "Bootloader logs"
  4.Press and hold the power key for a long time (7+ seconds) until the phone reboots.

3 button procedure described in my answer as first option is more elaborately covered here http://forums.androidcentral.com/verizon-htc-one/394469-battery-charger-reset-procedure-htc-one-m7-m8.html

Backup of apps and their settings I learned about Titanium Backup but I don't have a rooted device yet.

I'd still like to backup all my installed apps and their settings - will the default Google backup:

What does this backup exactly?

Sorry if this has been answered before but I really couldn't find it on quick search. So maybe it won't hurt to have my post here.

I see that my best option is adb (Full Backup of non-rooted devices) though... but I still don't know what the default Google backup does then... and why it's not enough...

install Helium - App Sync and Backup & APK Extractor (to backup your APK) from playstore it might help you but it will not save your settings

Disabling data traffic notification "A total of consumption during the lock screen" on LeEco Cool Changer S1 A couple of days ago I received my new phone, a LeEco Cool Changer S1/Coolpad Cool S1. Every time I lock it, I get a notification titled "A total of consumption during the lock screen..". If I open it, it launches the Android settings app and shows me a list of how much data each app has used while the device was locked. I don't really need this and I find it to be quite distracting, I have looked everywhere in the configuration and I could only find options for disabling a daily data limit reminder, which was also set by default, at a measly 30 MB.

I believe this may be something specific to this model in particular, and I could not find any useful information by looking for the exact name of the notification online, which oddly is also one of the few messages that are not translated.

Is there a way to get rid of it?

Here is something you can try:

Long press on the notification, you will then see an icon like this "i" press on it, and you will see a setting for disabling notifications. Set it to 'off' and you will not see it again.

There must be a more direct way of doing this, but I don't have your phone to test it.


Can the LG K20V be rooted? I can't find anywhere stated the LG K20 phone can be rooted safely.
Does anyone know if its possible? And what steps do you take? Thanks.

The LG K20V is a Verizon phone, Verizon phones come with locked bootloader, and there is no known way to unlock the bootloader. It is not possible to root without unlocking bootloader, so it is not possible to root a LG K20V phone.


How can I clear individual cookies on firefox? For a specific website, I clicked on "Show desktop version" link. Unfortunately the desktop version is so broken I cannot use it even to click on "Mobile version" link. Because the website remembers the setting using cookies, I need to clear that specific cookie to get mobile version of the website back.

When I use "Guest mode" in Firefox, the website works which confirms my hypothesis that cookie causes my problems. Therefore the question: How to delete one specific cookie in firefox on android? I tried installing some plugins, but all I got was "Installation failed" toast message on screen.

Firefox for Android stores Cookies  in /data/data/org.mozilla.firefox/files/mozilla/{YOUR_PROFILE}/cookies.sqlite.

You can't peek into Firefox's data directory without having elevated privileges than what is granted to a normal user, call it superuser access. If you have root access then simply pull that file into PC and open it in an SQLite viewer. Search the Cookies using domain name and purge the ones bothering you. Save the changes and push the file back to its location. When doing that, make sure to delete the files cookies.sqlite-shm and cookies.sqlite-wal in the data directory of Firefox. They are temporary files created when cookies.sqlite  is opened.

For a non-rooted device, you may consider pulling the data directory using adb backup. Extract the backup using ABE. Make the changes, pack the directory into a backup file and restore it in the device. I don't guarantee that restore would work.

There are some addons here which you may try and tell us if they work. They should work regardless of superuser access.

android keeps on restarting with optimizing apps Problem:
It constantly restarts with optimizing apps.
Some Background:

This phone was running on low disk space some days back, which I
resolved by removing unwanted files.
Some apps are third party apps installed by downloading from websites.
I have searched other threads and none seems to be solving my issue.
I have done a "cache wipe" as well, which didn't solve the issue.
This has android version 6.
I am able to run Fastboot and have access to Fill-Z touch recovery.
I obviously don't want to format (easy solution) this phone as that
would delete all the data in there.

Extra resource:
vimeo link describing problem
If anyone can let me know how can I disable this "Optimizing app" before the start, I'd be glad.
Any help would be appreciated. Thanks in advance!

I had a similar issue not that long ago: the culprit seems to be some app ART cannot compile for some reason. As you successfully applied my solution and confirmed, let me sum up the facts from the comments in an answer:

1. figure which app is the culprit.

On each of those crashes, the Android system sets a "tombstone" on the "grave" of the dying process – something known on Unix/Linux systems as Core Dump. Those core dumps are placed into /data/tombstones, with at maximum 10 files kept (after that, the oldest one will be overwritten on the next occasion). So we need to look to those tombstones to see whats written on them. As you have a custom recovery which offers adb access, the easiest way is:

adb pull /data/tombstones tombstones (will copy the entire directory to your computer)
use a viewer/editor of your choice (best one you are familiar with) to open and investigate each of the tombstones, starting with the newest and walking back.
look into the "stack trace" to see if an app (or it's path in /data/data) is mentioned there. If so, note it. If it's the same app in the next tombstone and the one after, you can be pretty sure this is the case we're describing here.

2. put the "obstacle" out of ART's way

Having identified the app, we need to remove it so art doesn't get stuck with it. For this, again we need adb shell with its root prompt – and the directory name from our tombstones:

rm -rf /data/data/<whateveritwas>

Note this removes all the data of the app as well – so having a backup in advance might be a good idea (in the current state: either adb pull the directory, or do a nandroid backup you can analyze later).

That done, reboot. Now "optimizing apps" should finish successfully.

Alternatives to the command-line approach

Some custom recoveries ship with an integrated file manager, usually called "Aroma". Above steps could also be perfomed with that:

navigate to /data/tombstones
view the tombstones
navigate to /data/data and remove the offender


How to grant write access to external SDcard using ADB in Android tv? I can't get ES file explorer and winrar to write (copy or cut from internal storage and paste to external storage) to SDCard external storage in Android TV. It says that there will be an "open from" window where I can enable it, but the window won't appear like it did in my android tablet. Is there an ADB command to grant writing access to external SDCard?

I tried to use these commands:

adb shell appops set com.estrongs.android.pop WRITE_EXTERNAL_STORAGE allow
adb shell appops set com.estrongs.android.pop READ_EXTERNAL_STORAGE allow

That was the code for es file explorer, for winrar I just replace com.estrongs.android.pop with com.rarlab.rar The codes executed with no errors, however, I still can't write to the external SDcard, the suggestion to enable it in the supposedly upcoming popup window still appears and the popup window still did not appear. Please help

Android Marshmellow (API 23) or above you need to grant runtime permission. This can be done through an adb shell with the command:

adb shell pm grant com.your.app.package android.permission.WRITE_EXTERNAL_STORAGE

If you ever need to revoke the permission the use this command:

adb shell pm grant com.your.app.package android.permission.READ_EXTERNAL_STORAGE

how to close an application in android Possible Duplicate:
  What is the right way to close apps in Android?

Is there any proper way as suggested by google or android official documentation to close an application in android with out using any task killer tools ....

I ask this question as a android use not as developer.....

Android keeps closed applications on memory as long as possible so that when you return to the application it will still be on memory and will load faster than loading from the internal memory or SD card; but if another applications needs memory, unused applications and background applications will be automatically force killed to give way to the foreground activity.

In short, Android is not Windows, don't treat them the same.

You should only force close misbehaving applications, not for freeing memory; without a dedicated task killer, you can do this from Settings > Applications > Manage Applications > *name of application* > Force Stop

Pressing Enter key with an external keyboard doesn't send SMS on Panasonic P100 I am using a Panasonic P100. I want to use an external keyboard to SMS to my friend, but the Enter key is not working to send SMS.

The Enter key can produce 10 (hex 0A), 13 (hex 0D) or 10-13 (2 characters, 0A, then 0D), depending on the operating system it was actually designed for.  The SMS app may be looking specifically for 10 (0A), because that's the Linux EOL (end-of-line) code (and Android is running in a Linux OS).  Use the mouse to click the (in most SMS apps) forward arrow on the screen.  (Or try alt-10 - hold the alt key while pressing 1, then 0, in turn, then release the alt key.  That produces the Linux EOL character.)


Is it possible to return back to jelly bean OS after upgraded to cyanogenmod? I am using samsung galaxy Star Pro 7260 (rooted). I would like to install cyanogenmod on my phone. But, I want to know is it possible to return back to jelly bean OS after upgraded to cyanogenmod ? If it is possible then tell me what I have to do before installing cyanogenmod on my phone ? Do I have to take any backup (OS) from my phone ?

Usually, this is possible the very same way as you put CyanogenMod on your device: by flashing a ROM. So before you start, make sure you either...

have a stock ROM available to flash (see: Where can I find stock or custom ROMs for my Android device?)
have created a nandroid backup of your device immediately before you start flashing (requires a custom recovery, see recovery-mode)

In both cases, you can return to stock ROM: either by flashing a stock image (and then start like after a factory-reset), or by restoring the Nandroid backup (and take off at the time you've created it, including all your apps and data).

Two things to consider:

there might be dependencies between device-firmware (ROM) and radio-firmware. So if installing CyanogenMod (or any custom ROM) goes along with a different radio image, a return might be different (you might need the original radio image as well) or difficult (in case downgrade of the radio is not possible). However, cases where this applies are rare.
Nandroid backup doesn't take care of your SDCard. So if you have apps installed on SDCard, you need to deal with them separately.


Emmc replace (inbuilt memory card mounter) with external memory card mounter Hi friends i want to increase inbuilt memory at infinity level by replacing Emmc holder (inbuilt memory card mounter) with external memory card mounter, can it be possible? If yes how? If NO Why??

There's more to just internal storage in eMMC - it holds a vast array of partitions. Here's an example I just got from my phone.

As you can see many of those "blocks" (mmcblk_p_) correspond to major functions of the phone. Even more, such as EFS (stores baseband info) and sbl* (bootloader) aren't even listed here because they're even more crucial, are loaded at boot time, and doesn't allow a regular user to tinker with.

Now imagine all those partitions all shifted to an external, removable source. With proprietary formats, is it possible in the first place? Even if yes, what if one removes the media in the middle of booting up?

And lastly, eMMCs (and recently-introduced UFS2s) are significantly faster than your average SD card. Running Android on a Class 4 SD card is actually a painful experience - if you don't believe it, burn Android-x86 onto an SD card and try booting from it.


How do I enable USB debugging from TWRP After a series of idiotic events on my parts, I have ended up with full software wiped (including stock os) without USB debugging or any roms to flash. I am able to access TWRP but pretty much nothing else. If details on the events are needed to help, I will gladly disclose them. Immense thanks to anyone who attempts to help.

Your concern right now should be to flash a working ROM in your device. That can be done easily using TWRP. Connect the device when booted into Twrp to PC, and the PC would see it in MTP mode. You can then copy flashable files to internal storage from PC. TWRP, in addition, comes with USB Debugging enabled, so you can do sideloading as well.

Alternatively, you may have to rely on some MI flashing tools, but I don't have an idea of how they work.

Regardless, if your OS is wiped out there is no point thinking about enabling USB Debugging there, because it cannot help you flashing a new ROM. ROM is flashed only via recovery or low-level boot environments, such as fastboot. Furthermore, the concept of USB Debugging assumes there exists a functioning OS (recovery or fully-fledged Android) which would receive the debugging commands. There exists no Android OS, so it is futile to think about USB Debugging.


Cant enter recovery mode Galaxy Tab S 8.4 I have an issue on my device (Galaxy Tab S 8.4). I´m either stuck on boot loop (flashed with TWRP that worked fine for months until recently after a restart) or I can enter download mode and get stuck at the "Download... Do not turn off target!"-screen. Cant ever enter recovery no matter how I try... If I let the battery die it boots up into the boot loop as soon as I plug in the power chord. Is my device bricked or whats going on?

I had the same exact problem. I flashed a Marshmallow ROM from KitKat, not realizing I had to update the bootloader to Lollipop. I got stuck and couldn't get past the boot screen and when I used pwr+vol dwn+home I got the Download...Do not turn off target msg. What worked for me was to plug in my Tab to my pc, start up Odin 3.09 (not sure if the version matters, I didn't try 3.12) and I was able to flash the Lollipop boot loader. The Tab restarted and I was good to go. Hope that helps

No. Only skype or other voip options. It does not have a GSM module on it, it just has a small chip for data transfers.


Is there any relation between charging rate and discharging rate? Sometimes when I do not use the  original charger but a different one it would take less time to fully charge the device than the original charger would do. But I can feel that discharging rate is higher after using these chargers.

Is it true?  If it is true, then what is the actual reason?

I think not. faster charger actually put more energy into your battery (1A = 1W * 1V^-1). your battery's Voltage is at charging and discharging the same (or to be specific, it's rising while charging and dropping while discharging, but the same amount *), so basically the difference between the two chargers is the energy (A) which comes, and because of the same Voltage (V) the Power (W) must be different. if you discharge, the processor (and display,...) consumpts power (W), but the Voltage is still the same.

* what is not the same is how fast your battery would discharge in relation to the actual charging percentage (or, better known as slower charging at end of charging)


What does "Archive does not contain 'android-something.txt'" mean? So I am trying to flash my OnePlus One with CM12s through fastboot on command prompt, but whenever I type fastboot update romname.zip I am presented with:

archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt

the specific build I am using can be found here It is the build ending in 8, or the one submitted on 2015-07-08

What have I done wrong?

I never flashed a ROM using a .zip in fastboot. The proper way I've ever seen is to flash individual files, and some of the important commands are:

fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash userdata userdata.img // 64GB users need userdata_64G.img

Provided that you do have these individual files in your .zip.

These kind of zips are called as "fastboot zips" or "fastboot images", while those requiring a custom Recovery (as keepclam mentioned) are plainly known as normal recovery-flashable zips.

I'm not aware of custom ROMs providing "fastboot zips", but if you intend to gain an experience of flashing such zips, I would suggest flashing a stock CM12s. You can find the related info on OnePlus Forums here.

About the error, it says you don't have android-info.txt. That's true that you probably don't have it because as I said custom ROMs usually don't provide "fastboot zips" which has this file. And I also said to try stock CM12s fastboot zip since it has that android-info.txt whose content would be like:

require version-trustzone=TZ.BF.2.0-2.0.0109

I think things would be clear for now.


Where can I find a comparison of Android devices? I recently got fed up with my previous smartphone (name omitted) and I'm considering switching to an Android based phone.  However, I have been stumped by the sheer number of handsets.  I'm more than willing to change carriers and I have no preferences in keyboard style.

What I am looking for (and cannot find on google) is a comparison of features between different Android phones so that I can make an educated decision (or at least whittle that decision down).

http://en.wikipedia.org/wiki/List_of_Android_devices

This link to wikipedia shows a list of Android devices. If you scroll down to the table with the section headed Released, Installed devices you will see a list of smartphones. I would recommend clicking on Version twice, to sort with the latest Android version eg2.2 ( and consequently newer phones) at the top.

You will notice that the Evo 4g and the Galaxy S are near the top. This should help to narrow down your choices.


Record Nexus 10 screen I am trying to find a way to record the screen on my Nexus 10 tablet.

I make promotional videos for my company to show off our cloud-based software. I need a good way to show people that mobile devices can be used to make great use of our software. We use Nexus because it has the NFC chip reader and writer.

Is there any way to do this that does not require rooting?

Your Nexus 10 should be able to upgrade to the newest Android 4.4 Kitkat any day now. It has a new option to record the screen, but you need to be/know someone who has basic knowledge about the Android SDK: http://developer.android.com/about/versions/kitkat.html#44-screen-recording

Since you did not accept an answer yet, hope this info still helps and I'm not necromancing your thread. ;)


Can I create folders I have a Samsung Galaxy s6 with Nougat.

Please,I'd like to know if I can create folders in Archive>Documents.

Thank you

on stock non rooted phone you cannot make the Archives folder you seem to refer to in root (top level) directory. However you can't even see root dir in many files managers.
So in a file manager, (I use es file explorer, but frankly it's getting bloated, so I dunno what to recommend) just go to sdcard & make an Archive & Documents folder (either way you need them) or just click into them or they're already there. you can also do it from the command line with a terminal emulator. this gives you Linux street cred & will boost your confidence, but more people go the easy way.

cd sdcard
cd Documents
mkdir Archive
cd Archive

blocking callers from leaving voicemail how do I block a caller from leaving a voice mail on a prepaid plan.I have a lg g2?  I don't want a certin person to leave a volcemail

You might wish to take a look at Extreme Call Blocker. That app is on Playstore for already 5 years, and claims to work from Gingerbread (2.3.3) up to Lollipop. One of the explicitely listed features is:

  New blocking feature: Allow the call to ring through, but prevent it from leaving voice mail.

Which should be exactly what you're after. For possible alternatives, be welcome to take a look at my list of Call Blocker apps.


my usb dont show up on my android device so i bought a USB to micro USB cable to use my USB on my android device.
and normally when you plug it in you get a message above that says it is connected
but when i plug it in the message does not show up on my phone and when i use it on my tablet it works.
i already tried an USB otg check app and it says that it is compatible.
i also tried another USB but that did not make a difference.
is there someone that can help me with this please ?

Yes it's natural. In some phones the OTG doesn't work, because it's unable to provide the power needed to function the external device you're trying to connect. In your case the tablet gives the power needed while the phone doesn't.


Quickly send file from phone to PC via internet? Is there a service/app that provide this functionality? I imagine the inversion of Awesome Drop.

A service like Dropbox should be able to do this for you. It'll sync the files up to the web, and then your PC (with Dropbox installed) should pull them down.


What could be the source of error for this kind of android wireless (wifi) disconnection? Recently there was wifi connection problem for my LG G2 (Android 4.4.2). It has internet connection and was able to connect to AP but sometimes it faces connection drop, no wifi connected although the wifi trigger was still on. During the connection drop, the phone appears to linked to wifi, but i noticed there is no data connection when i monitored live using some wireless monitoring tool. The wifi auto disconnect even i have the strongest signal connection (router was just below my desk) and there was proper internet connection for my laptop which is connected to the same AP.

Thus i would like to be advised is this the source of error from the hardware itself, or from the stock LG G2 ROM (Software)?.

Thanks

Edit: It occurs in each router that i connects

Try to change the channel of your wireless router. Maybe it was caused by the congestion of the working channel(Maybe channel 1).
