[Q] Power button not working - Nexus 4 Q&A, Help & Troubleshooting

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 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

[Q] Cant access power menu. SOLVED

Long pressing the power button does nothing. The power menu does not come up, and as soon as I stop pressing it the screen turns off( the long press registers as a quick press so waking the screen on/ turning off is fine).
Any ideas what i can do ? Maybe force stop a certain service that would refresh the whole UI or something. My battery is at 9% now so I can wait till the battery dies and reboot it after. But im afraid it wont turn on if it was a hardware fault ;/
EDIT:
Solved. Had to do a hard reboot for it to work(holding down the power button for 10 second). Now it works fine, and i feel stupid . Lock please.

Yes i know that this method could work but what is strange is that the menu with all the options like sound,turn off ecc won't show up if i hold power button and i think that if i turn it off maybe it won't recognise the long press action when i'll try to turn it on

Press and hold the Volume up and Power buttons simultaneously to simulate removing the battery. After your Nexus shuts off, go ahead and power it on normally.
Are you using a custom ROM?

Possibly the SystemUI is bugged, I had this issue with CM nightly around May. Reboot then it'll be fine again, until you trigger the bug.
I am all stock, i only have an unlocked bootloader, i held power for 15 seconds and it rebooted now all is working,thank you guys i was really scared

[Q] Nexus 4 died weirdly

ROM: Cyanogenmod
Android OS ver.: 4.4.2
Device: Nexus 4
Apparently, using CleanMaster to clear up RAM and locking my phone at the same time is a bad combination.
My Nexus 4 is now bricked somehow.
I remember my battery is about 60% and above.
My "Hold" button is broken so I used Cyanogenmod's double tap on status bar to lock screen function mostly.
The "Hold" button will work if I pressed the "Sweet" spot.
I tried calling my Nexus 4 and there's a dial tone but my Nexus 4 do not have any indication that there's a call.
No vibration or ringtones.
There isn't any LED light indicating my phone is in critical state.
I believe my Nexus 4 is still "Online" as I still can call it.
Please help! What should I do now? I think I'm the first one to have this problem.

Well, I don't know if i'm pressing the "Sweet" spot but I tried holding for more than 60 seconds. Nothing happens.
I think my phone is having CPU or RAM lock?
Any more ideas to force reboot my device? :crying:

I've tried and held it more than 60 seconds again.
both holding Volume up + Power and Volume down + Power doesn't work.
Thanks for the suggestions though!
I'm still confused.. why did this happened? :l
Oh.!!! After constantly pressing volume up and down with power button and power button alone.
I couldn't tell if my phone had shut down, I tried calling my phone and there was no dial tone!
I tried powering on at the same time and a logo on the screen came up!
My phone is working fine now!
Lesson learned: Do not Clear RAM with Clean Master and lock screen at the same time.
Current Battery Level: 25%
Thank you all!

glad it's working. just to let you know you don't need to clear ram since Android 2.0 eclair. So don't use those apps.

Problems with power button

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
