Power button doesn't work after boot

So here's my problem, I can press the power button to start up my touch pro 2, but after the OS loads, it doesn't function to turn off the screen or to power off my device. So now, it just goes dim after 30 seconds but still stays lit and the only way to turn the phone off is to pull the battery. What can be done?

Witch rom do you use? What kind of cabs did you install? Other tweaks? Please be more specific so we can help

Stock Tmo Win6.1 rom. Nothing installed really, this problem was present ever since the fresh install. It can't be physical because the power button is recognized prior to OS boot, and I can get into the bootloader fine as well.
Maybe there is some software that can map the keys properly?

Try this program and see if it solves you're problem. I will let you remap you're hardware keys.

That program doesn't let me do anything with the power button. It doesn't even let me assign a power button FUNCTION to the end button. I don't know what's going on.

There are different restart programs you can install that will include an app. You should change the times for your screen to turn off as well. If there isnt' water damage take your phone in to the provider and you should be able to get a new one.

Formatting Tablet Help

OK, so my little 9 year old brother got the Acer Iconia Tablet A100 so he wouldnt feel so left out that everyone else in the household has a tablet but not him, well he thought he would be smart and turn off the wifi and place a lock on it. Well he forgot the lock code and after many attempts he has to login with his google credentials, but the problem is that the wifi is off so it wont fix anything. So im trying to format it for him, I can get to the recovery screen, but only the volume buttons will work and the no other button will let me confirm the selection. Dose anyone know what i can do?

1. Place the rotation lock switch in the up position
2. Press and hold the Volume down button, which is located farthest from the rotation lock
3. With the Volume down button held, press and hold the Power button for 3 seconds then release it. Continue holding the Volume down button.
4. Once the tablet vibrates, switch the rotation lock on and off repeatedly while still holding the Volume down button.
5 Release the Volume down button and stop switching the rotation lock once the "Erasing Userdata..." message appears in the upper left corner of the screen
6. Once the factory reset has been completed your tablet will load to the Welcome screen.
7 Your Factory Data Reset has completed now follow the onscreen steps to setup your tablet.

Hard reset the tablet, you'll lose everything, but it will revert to factory condition.
Power off the tablet
Hold Volume + (the one furthest from the power button/ lock switch, right if holding landscape)
While holding Volume + press and hold the Power button
Once it turns on, holding the Volume +, release Power and wiggle the lock switch up and down a few times.
Screen will then say its formatting or resetting or whatever it says.
After this completes, it may reboot, or power off, or continue booting into android, whatever it does, just let it go into android
It should greet you with the Welcome screen for setup.
Resume playing with it.

Can I do a hard-reset once I have unlocked bootloader & installed a custom recovery? Is there a way to go back to stock recovery?

You can still hard reset yes but it only erases user data nothing else.
If you want to go back to stock use one of the update.zip methods in vaches stock rom thread. It'll go back to stock recovery. If you want just the stock recovery there's a stock recovery.IMG around somewhere I'll see if I can find it.

[Q] How to disable random reboots by pressing power button in pants pocket?

I love this phone! But one thing is really annoying.
I keep this phone in my jeans pocket, but often while walking I hear the reboot sound. The power button is pressed in my pocket. And if this happens long enough, the phone will reboot, even when the phone was locked...
Is there a way to disable this behaviour?

If you install Widget Locker Lockscreen I think you can disable Power button at lockscreen but I don't use this app anymore for several months.

That's a paid app. Seems excessive just to disable this annoying behaviour

seems weird to me. I never had a reboot when phone was in my pocket. Prior to note 2 I had a S2 with same power button construction and behavior, and never expriened this.
Do you use a silicon protecting case? Those cases put a small but excessive pressure on side buttons thus a little push will trigger buttons.

No, I'm using it bare.
Hold your phone, locked with the screen off, and keep holding the power button. You'll see that it'll start rebooting.
I'm not wearing skinny jeans or anything like that, the phone has plenty of room in my pocket... But apparently it's enough to press the button e.g. while driving with my seat belt on.
The annoying thing is that I sometimes don't hear it rebooting and then I'm unreachable for hours until I look at my phone and input the sim code again. Now that I think of it, I think I'll disable sim code input, that will at least connect me again after a reboot.

The problem apparently already existed with the Note 1:
http://forum.xda-developers.com/showthread.php?t=1369805

On further googling, this actually is the soft reset feature!!
There goes my hope of disabling it...
EDIT: Another happy user: http://forum.xda-developers.com/showthread.php?t=1401852

I guess it would be possible to disable soft reset, but you'd need to build a kernel with the feature.

Try this app: https://play.google.com/store/apps/details?id=com.nezdroid.lockscreenprotector
Hi all i made an app to avoid this, blocking power menu on lockscreen no need of root working on 2.2+ and you can set up a custom menu (power and reboot need root) so you should take a look and if you like please leave a 5 stars, or let me know any issues
this is only for lockscreen , when you are outside lockscreen you have the normal power menu
here its the link to play store

EDIT
Or with a rooted phone:
Once the phone is rooted, you install an app called Root Explorer which you get from the Google Play Store.
With this app, do the following please
Go to system > usr > keylayout
Find seckey.kl
Made backup from seckey.kl file.(copy paste in same place then rename or paste to other folder)
Change seckey.kl permission to become 0777, so we can edit the file.
Using text editor open secky.kl
find
KEY 116 POWER WAKE
edit to become
KEY 116 POWER
Save the change
Change seckey.kl permission back to 0655
Reboot the device

Problem Solved

Put it in your left pocket. .. it happens if you put it in your right pocket

If my phone was rebooting in my pocket I would guess a ROM issue before imaging I'd pressed the power button too long.
Perhaps it's time to charity shop those skinny jeans.

Just in case somebody out there running a custom ROM has got the same problem and looks for an easy workaround:
There is a Xposed Module that allows you to modify the power button menu to your preferences and also to completely disable it when the phone is locked.
I have not tested it yet and it is unfortunately discontinued by the developer, but it looks pretty solid to me.
It was intended to run on Sony Xperia devices, but also works on many other devices with AOSP based ROMs.
ATTENTION: It does NOT WORK for TOUCHWIZ ROMs although you can install it to them via Xposed Installer!
Head over to the Advanced Power Menu XDA-Thread.
Cheers!

Don't use interaction control before you read this.

If anyone who doesn't know what interaction control is, it is a built-in feature that can be found in settings->dexternity and interaction | on Samsung phones. It is used to prevent a part of the screen or the whole screen from touching. After you enable it touch interactions won't work on the places you choose.
The best part of this tool is it ignores all the notifications as well as calls. It doesn't let you lock or unlock the device as well as physical or on-screen buttons won't work.
Now the worst part is if you run out of battery after you enable this feature you are in trouble.
For the first time when the phone starts, it asks for the locksceen password or whatever security you put.
The problem is when interaction control is enabled you can't touch the screen nor any buttons will work except back key which doesn't do anything and the power key which basically turns off and on the screen.
You can't turn off or on the interaction control while the screen is locked, and you can't unlock your device while interaction control is enabled.
Basically, your phone is in a loop. The only way to make the phone functioning again is the factory reset.
Even Samsung Customer Representative couldn't help it.
I know it is an extreme condition that it can happen.
But still, beware before using it.

Found this topic while googling for a different issue, but I thought I could shed some light on this. Sorry for the necro
At least on my Note 10+, you can enable and disable the Interaction Control feature by doing one of the following:
A) Hold down the Home and Volume Down buttons together. (Doesn't work if the home button is virtual (on-screen) and is blocked by Interaction Control)
B) Hold down the Side Key and Volume Up buttons Together. (Always works, even when Volume buttons and Side Key button is blocked!)
Edit: Just realized this topic is for the Galaxy A50, but hopefully it will work just the same

YES! Do NOT ever activate "INTERACTION CONTROL" unless you KNOW what you are doing or know what that feature is! Unfortunately, IF you are already here, you have probably already activated that feature and don't know what to do, because that is why I'm here too! I accidentally turned this feature on after taking a screenshot! Don't ask me how or why I managed to do it, because I just don't know, I just did. I tried to power off the phone thinking that would help, But I couldn't even do THAT! I was panicking! I was completely LOCKED OUT OF MY PHONE from activating this feature! I only accidentally found how to "disable" the feature pressing and holding the side button and power up button at the same time, like the other poster commented.

The reason you could disable it, the phone was still on. If you run out of battery, it will not allow you to disable it with shortcut keys before you unlock the phone. You can't unlock the phone because the screen is disabled. One way, maybe, is to plug in an external mouse and unlock it if your phone supports it. I don't have my A50 anymore, so I can't test it anymore.

You can't do it if your battery dies. The shortcut works if your phone is still on. Once the battery dies and you turn it back on, it will ask for a password before you can disable interaction control with the shortcut, which is stupid since you cannot unlock it with interaction control enabled since the screen is locked. One option might work if your phone supports OTG; you can plug in an external mouse and unlock your phone to disable this feature. It is better to use the pin app future which gives almost the same results. It locks you to the same app even though you can use the screen.

How to fix an only sometimes working power button (which also easily triggers double click)?

So the power button of my Pixel 2 XL is unfortunately dying. Sometimes it works a few times and then a button press does nothing. It also triggers easily a double press (noticeable because that starts the camera) when tapping it only once. Gets really annoying when you think you have powered it off but it is still powered on in your pocket...
Are there any ideas how to fix the issue without opening the device? I don't want to open the device by myself after I ****ed up my Nexus 6 after a battery swap.
Any workarounds for the problem? Currently I use Novas remapping of the home button for power off but that is not really comfortable because you have to leave the current app for that.

Different roms have different options that may partly help. Often they are at settings/system/gestures.
For wake, use fingerprint. For sleep, set a very short timeout, or see if you can find a rom with double-tap to sleep option. If camera starts at the wrong time, disable the camera quick start.
But none of this will help you if the phone is really turned off. Can you really live with not knowing whether you can start the phone if it runs out of power?

I will look into some of the options. I'd like to stay with the stock rom though (but I have root if that helps).
The button is not that broken. If I press really hard I can always get it to work again, so I have no fear it won't power on again.
