[APP][4.2+]Ringer Mode Lock - volume buttons fix - Android Apps and Games

This application blocks the ringer mode to avoid changing the mode when the phone is locked (screen on)
this is a workaround for the following strange behavior / bug on stock android 4.2+:
Note: my phone uses a pattern to unlock screen.
- Steps to reproduce the problem.
1.Lock the phone, and light the screen with power button.
2.Long press power button until the power off menu appears.
3.Press the power button to close the screen.
- What happened.
4.After that, every time the screen is lighted (but not unlocked), press the volume keys can change the volume though no music is playing at all.
The volume keys keep working each time I turn on the screen without unlocking, and it is back to normal when I unlock the phone use the unlock pattern and lock again.
- What you think the correct behavior should be.
The volume keys should not work at all when the phone is showing lock screen, it has accidentally muted my phone and led to missed calls. This is worse than power off menu it self. Since power off menu only appears with long press, but when ever the menu appears once, the volume keys work every time until I re-lock the phone.
And also I don't think the power off menu should appear by long pressing during locking state, since it is quite possible that the power button can be long pressed even in my pocket during taking the phone in or out.
P.S. When the phone is rebooted and went into lock screen the first time, the volume keys will work on lock screen without the necessity of showing the power-off menu.

My nexus 5 repeatedly going to silent mode

Hi
My nexus 5 running into issues again. .
It automatically goes to silent mode. After increasing the volume again it goes back to silent mode.
I can see the volume bar decreasing from full to vibration in front my eyes.
Also sometimes the power button won't work for sometime.
If I tried to reboot, it automatically goes into recovery mode without pressing any combination of keys.
Once I press volume button it goes into one of the recovery settings and gives a message NO COMMAND
After multiple hits of power button or some combination will boot the phone into safe mode sometimes..
Now I am stuck with its issue of automatically turns into vibration mode.
I am worried to reboot bcause it may stuck in recovery.
Any solution...
I used to have this issue in lollipop and got fixed in marshmallow..
But recent patch fix update in December gives the problem again. .
Please someone help or forward to a thread which helps to clear this problem,m
Sounds like you may have a sticky power and volume button.
Maybe open up the phone and swab around the buttons with a bit of alcohol, then rapidly press and release the buttons using slightly more pressure than normal. Not too much pressure though.

Screen sometimes not working

Hey,
When I try to unlock my phone with the power button, the capacity buttons light up and the screen also seems to light up but it is just black. The touchscreen is still working because I am able to restart the phone (by holding the power button and swiping down and then holding the power button).
The weird thing is that the phone just displays everything correctly if I power it on, but once I lock it, it all goes wrong.
Is there any way I can fix this problem? Thank you in advance!

Stuck in Safe mode, volume button issue

Hey everyone,
issue: Nexus 5 always boots into Safe mode
-volume button is stuck pressed but physically it is fine, I even removed the whole button and tried to turn it on, same issue
-when I turn on the device, bootloader appears with cycling options (i.e volume button issue)
-I swapped the whole mother board to another one, problem solved (borrowed from a friend)(gave it back)
-did a factory reset through stock recovery
-bootloader unlocked, TWRP installed, rooted
is there a way to "Force" your phone to boot normally?
or is there a way to disable safe mode?
or is there a way to disable the volume down button itself?
[Update 14 Sep 2017]: found a work around, tapping the volume buttons rapidly (alternating) while boot up, this fixes them temporarily, been 24 hours now with no issues
thanks

Help sm-g955u screen wont light up after it wakes

First of all I appreciate any and all help on this matter. My problem is simple yet the solution escapes me. My phone starts up fine works fine and there are no problems....until I wake it up from sleep. The phone itself comes on and I can tell that the screen wakes up, but there's no blacklight, just a very dark home screen. So far the only annoying thing i have to do is reset it and it works fine again....until it goes back to sleep. I guess my question is, is this an issue that can be resolved (software). Or is it unfixable without screen replacement (hardware).
You need to test a few things beforehand.
Does it only produce this issue if the screen times out, or by manually pressing the power key to turn the screen off, or both?
Does the screen appear dim when you wake it up via the power button, hard pressing the home button to wake, or using your fingerprint scanner to turn on and unlock your device or a combination of those listed?
I would try safe mode.
You can boot into safe mode by following the below instructions:
1. Power off your device in question
2. Press and hold the power button to turn on the phone
3. When the Samsung logo disappears, release the power key and press and hold the volume down key
4. Continue holding the volume down key until the phone has finished restarting
5. You should now be in safe mode and can verify by looking in the bottom left of the screen for text that states you're in safe mode
After you have successfully booted into safe mode you need to allow your screen to turn off manually, automatically, or both(whichever results in a dim screen when normally booted up) when testing the below steps.
Turn your screen on via the power button and see if the issue remains.
Turn your screen on via the hard press to wake home button (not sure if this is available from safe mode, but worth a try) and see if the issue remains.
Turn your screen on via the fingerprint sensor (not sure if this works from safe mode either) and see if the issue remains.
If all successfully turn on the screen with normal brightness then I would say it's more than likely NOT a hardware issue. If one or the other does not produce normal screen brightness then it's more than likely hardware. If all result in a dim screen then it could be either hardware or corrupt software.

The problem is reproduced irregardless of the method used to put the phone to sleep. I will give it a try in safe mode tonight. I also wanted to add that randomly the screen will power on normally but never on the first wake attempt.

Let me know the results of safe mode once you have tried that.

It still reproduces the problem in safe mode. i tried to wake it with the power button, home buttonand the fingerprint sensor... also under forced sleep mode and letting it time out itself.

At this point, it's more than likely hardware but because it's intermittent you could try using Odin to flash firmware. I would advise you to look to the appropriate forum for instructions. And as always, if you have the ability then backup the data you wish to keep, do it prior to flashing the software.

Well I figured it out. there was damage to the sensor that determines how light or dark it is. If I cover the top part of the screen with my finger then wake the device, it comes on every time. I hope this helps other people out in the future.

Try this then:
Under display settings turn off "Block accidental touches"
See if that results in not having to block your sensor every time.
**Edit**
By the way, glad you figured it out.

Volume button down issue

Hello.
I received my Pixel 4a recently and now feeling like the most disappointed person in the universe.
The reason is that the left button seems to be somehow stuck - but in a software way as it clicks perfectly (the phone is or should be new), but does nothing, and while button is not being pressed, the volume turns down on itself to the bottom, and tries to be turned down even then. There is more - the power button does not work, and I can not turn the screen of. And when I hold the power button, the phone does not reload - it goes into fastboot as the volume button is "being held" by default. And there is even more - in fast boot the volume down button also doesn't do anything, and the power button also acts as an options switcher instead of enabling them so I can not even enter rescue or recovery mode. The only way to boot then is to hold volume up button after holding power button so it neutralizes the volume down button effect.
Any help would be much appreciated
