Problems with power button - AT&T Samsung Galaxy S7 Edge Questions & Answers

Hey guys I've had 2 s7 edges the second one being my current one. They've both had problems with the power button, it won't work. I push it and it doesn't turn on the screen nor does it turn it off when the device is on. Has anyone else had this problem?

Mine is working fine

There seems to be a bug where the volume down and power button become unresponsive. Holding down power and volume down together will make it reboot and fix it.

I can confirm that holding down the power button and volume down even tho they seem unresponsive, still reboots the device and resolves the issue. Hopefully it doesn't come back

power button wake up problem

press harder. I learned quickly that it takes a firm push and you have to hit the button w/o your fingers getting caught up on the sides of the phone.
it's either that or you got a bad button
I have the same issue, this along with the lag I get at times when I attempt to use the camera has me seriously considering returning this phone. The Inspired I returned had non of these issues just a tinny speaker.

Mine wouldnt go to sleep today when pushing the button. Seems to be a few bugs with this phone eh?
I'm starting to look at re-mapping the keyword to allow the volume keys to wake it up, and then use the fingerprint reader to unlock it. That power button seems to fragile to me. To turn the screen off I just use Extended Controls.
Any thoughts?
Widget locker has an option to use the vol buttons for wake
I kinda have the same problem but its when i press the lock button the screen shuts off but then comes right back on. I press it again, it shuts off, then comes right back on.
I had the same problem - power button wouldn't wake phone from sleep.
I had to do a battery pull to resolve the issue.
I'm using the lastest FW.
Motorola phones (Not just Atrix, but Droid X also) have some funky business that sometimes prevents/delays the screen from turning on, even if the button press is registered. This happens with the power button and also the volume buttons if they're used to wake the device (Like with WidgetLocker). I haven't been able to narrow it down, but I suspect it's related to (ab)use of PowerManager's preventScreenOn()

It sounds logic to me, because even editing the right keyboard file to add a wake_dropped to the volume down, it won't turn on the screen. I hate when they change things the way they do with this, the bootloader, etc.

[Q] Power button not working

Hi,
after unlocking and rooting my Nexus 4 I flashed the franco-kernel. I did these steps with the ToolKit. But now when I start my phone I can press the power button once and it offers me to shut it down. After that there is no reaction when pressing the power button. I tried to reset the Nexus but I still get the same error. Can anyone help? Thanks!
EDIT: My nexus just turned off the screen and I was able to reactive it by pushing the powerbutton. What works all the time is shutting down the phone by long pressing.
From your initial post it sounds like it might be sticking..

I don't think that it's hardware related. It might be a software issue. Sometimes the screen stays on for ever unless I open an app and close it again. It seems the phone doesn't know what to do when the button is pressed.
EDIT: When connected to PC I can use the button only to power off the phone. I can't wake it...weird

Nexus 4 sleep/wake button problem read?

At times (occasionally) I find myself pressing the wake button while my nexus 4 is on sleep at most 3 times in order for it to wake up.
Is anyone else facing the same problem?
By wake button, I assume you mean the hardware power button? If so, I've noticed that I need to press firmly on the center of the power button to guarantee waking up. If I push on the edge, it doesn't always work even if the button "clicks".
I haven't noticed any issues but I do have a bumper ($5 Poetic) and I can just slide my finger over with a little pressure and it responds. Not sure if it's hardware or like tengen said that you might not be hitting the middle, but there are quite a few ROMs out there that let you wake with the volume rocker as well, nice feature.

Nexus 4 not waking up (screen not coming on with power button)

Twice in the last 4 days now I have come to my phone pressed the power button to wake up my phone and nothing happens. Both times I have had to do a hardware restart with power and volume up pressed.
It has happened after it has been fully charged when I go to use it first thing in the morning. Probably not an alarm as it happened on Saturday first and there was no alarm set.
I know the phone was still on because on the second occasion the notification LED was not flashing but got no response.
My alarm never went off. I am fortunate that after the first time I questioned the reliability of the N4 and set my N7 as a second alarm.
Only App I have recently installed is Chrome Beta, uninstalled to be on the safe side.
Has anyone else had this issue, or got any idea what could be causing it!?
Fingers crossed 4.2.2 is real and it has fixes for this stuff!!!
Try doing a factory reset. Are you rooted? What kernel are you using?

Just stock factory. Very few apps installed as I don't use that many (browser for most things).
Could try factory reset...
while your screen is on and in the home screen, long press power button until you get presented with shut-down options, then long press the "power off" button until you're presented with "reboot to safe mode"
use your phone in safe mode for a day or two and see if the problem repeats itself.
if the problem does not repeat itself, that means an app you've installed has changed something.and is the cause of your problem.
Try press the volume button before press the power button to wake it up. I also encounter this problem occasionally and manage to turn the screen on with the volume down then power

Volume Down and Power button don't seem to work anymore

Something just happened to my phone where the touchscreen actions went a little crazy for a second or two and then the Volume Down and Power button don't seem to work anymore.
The Volume Up button still works though...
Has this happened to anyone else? Is there a way to turn off or reboot the device without using the power button?
Volume down, power and home button. All 3.

Thank you!
Actually, I found in this case holding down Volume Down and Power caused the phone to reboot. I wonder if something got stuck...
It happened to me as well and I found some article which said to hold power +down button for some time and it will reboot
