Power button issue - Nexus 4 Q&A, Help & Troubleshooting

Hi all,
since I upgraded to Android 4.3 (and still now with the 4.4), I'm experiencing a problem with the power button.
In particular, when the screen is off and I press the power button:
1) Sometimes it works
2) Sometimes the screen keeps off and I have to press again
3) Sometimes the screen powers on and immediately powers off... and I have to try again.
The same happens when the screen is on...
I had CM10.2 with Franco kernel and I thought it was a rom/kernel issue... but now I flashed the stock factory image of Kitkat and the problem is still there. Anyone with the same issue? I hope it is not an hardware issue...
Thank you.

Problem with Power off

I have problem with power button. when push pwr button dont,t off pda, but when hold pwr then lights off.
Power is never shut off in PDAs, thats the way PDAs have been designed.
I have the same problem, he is not talking about a full power down. If you hit the power button quickly the phone does nothing. However if you hold the power button down for about 2-3 seconds the lcd light turns off as it should.
Because of this I have to wait 1 minute for the unit to suspend before putting it back in the holster.
Does anybody have any idea as to why this might be happening. Im not new at this so hard reset, soft reset.. new rom... new radio...turning up side down while chanting. It does not change......
It will do it right one or twice in a week.
Maybe somebody that understands the signal that the unit receives upon pressing the power button might be able to shed some light on this.... Again the button does seem to operate just not suspend when pressed normally (1 second or less)
I have done some more research and this seems to be a common problem for some with BAs but nobody has found out why. There must be some kind of common hardware fault.. Does the power button send only one signal or is it a multi signal device.

Do you have a problem with turning on? First, we need to know whether it is hardware issue or not...
What you can do in the mean time with the turning off problem is by installing a poweroff app like shutdownme, psshutxp, etc etc...
Absolutely no problem with turning on from standby... Right now i just lock the phone before placing it back in the holster.
To make it clearer if you HOLD the power button down the backlight will turn off only. It will still show the display image and keys will still function (it dims)
Well, I had the same issue with the latest WM5 ROM. I thought I was too stupid to press the button, then I thought the button was broke, then I thought, I'll have to live with it.
Now that I have flashed to WM6, no problems at all! Never even came to my mind that this problem once existed. So I guess that some ROMs just have this particular bug?

I have tried all the roms as well as 2003 and have the same issue in all of them. And im not alone.
Power off Problem
I'm in same condition.
Had the same problem when using WM2003 second Ed.
Now I've installed WM6 but nothing changed:
I cannot power-off/suspend but can turn off backlight if press and hold power button.
When in standby the button works fine to turn on the device.
Also, sometimes volume turns up continously with "noisy" beep ...
Anybody solved this problems?
Thanks,

radio 1.12.00 )
Power button has two modes:
1. Click mode: Click it once for a short duration. This turns off backlight and can be resumed by pressing it again or by pressing OK button
2. Press and Hold mode: Press and hold for few seconds and release. This mode will dim the backlight and no other button will bring it back. This is some kind of deep sleep in battery mode. To resume the original setting, press and hold Power button again for few more seconds.
(p.s.: I am not sure if this behavior is true for all the BA models)
April 1,
I know these modes...
It seems that "mode 1" doesn't work at all...
I would activate "Button Lock" (settings-->button--> Lock(tab)--> "lock all buttons except power button") to turn-off backlight and "lock all buttons except power button" but I cannnot...
You solved this problem?
I have had this issue of not being able to power off. One way I always got out of it was by clearing the registry hive. Unfortunately this brings the PDA back to the basic ROM. At this point the power button worked without any issues. Upon reloading the software the problem may come back. I believe the issue is related to some programs. I can't recall which program it was that seemed to cause the issue. One other thing I think that also worked was just entering the registry and getting back out and doing a hard reset.
I had the same problem with my 6600. the message button also didn't work. Believe it or not, to fix it. I banged the lower half (4-way area) on my desk a few times. Not hard enough to break the screen. But prolly hard enough to free what was prolly a sticky key. And now everything is working.
i am too
the same ...
when i press the power quickly , nothing happen
when i press the power for 2 sec. the backlight turns off
i tried every thing .... including formatting my BA
any one solve it ???
I have this same problem, my power button does`t work. i tried installing different roms but without any chance to fix it. maybe its an mechanic issue. i will change pwr button, i hope this work.
Look at one of my previous posts. I fixed it, twice, and other users have used the same metod to fix it. I think the problem is "hung bit" hardware related because you can also send it in for service, and they will change a chip, but i never had to.

Big, big trouble

Sometimes if i want to change the volume, i'm pressing vol up (or vol.down) and suddenly (sometimes) pressing on/off button too. After this screen becomes black and it is not turning on. Helps only taking off batery.
anyone else encountered this problem?
this bug is in all stock and custom roms, even in tango (rev 1.3)

[Solved] Nexus 7 Power Button

Hi all, I am having a very strange problem with the power button on my Nexus 7. The problem is that sometimes when I press the button the screen does not come on and I have to press it several times or I have to press it very hard to get the screen to come on. Pressing the power button to turn the screen off does not cause any problems though. The fact that the screen would turn off okay but not turn on made me think it was a software problem, but doing a factory reset or switching ROMs didn't help so maybe it is a hardware problem. It also happens in recovery mode (TWRP 2.6). I can turn the screen off and on rapidly with the power button with no problems, but once the screen is off for more than a few seconds it's hard to get it to come back on. I thought maybe it was sticking or something, but again I never have any problems turning the screen off. I bought the device used several months ago, but it was originally purchased over a year ago so I don't think warranty will cover it. I only noticed it start to do this in the past couple of weeks or so. Any suggestions on how to fix it? Here's what I tried:
1) Factory reset - No change after the factory reset
2) Flashing a different ROM. I was running stock rooted 4.3, also tried SmoothROM and cyanogenmod but get the same problems. Also have the same problem in recovery mode.
3) Opening the back case - didn't notice any physical problems with the button. Even when I press the little round metal button on the inside of the device that corresponds to the power button I get the same problem. It makes the normal clicking noise but nothing happens unless I press very hard.
Anyways, it's not the end of the world I just have to press the button very hard to get it to wake, but it is a bit annoying and would be nice to be able to fix it.
Update: Ok, this is strange, but I just did another factory reset and it seems to be better now. I'll keep you posted in case the problem returns.
Real strange!

Pinpoint An Issue

Guys, I booted my Nexus 4 in Safe mode, but still notice that whenever I press the power button to turn the screen off it comes back again. I have to do this a few times before it turns off. It doesn't do this all the time, but more so rather than not.
Another issue I have is that sometimes when I long press the power button the options to silence, vibrate and shutdown do not come on.
I'm thinking the first issue is hardware related, but with that second issue it makes me think that it's software related. Could someone shed some light on this?
Thank you.

[Q] Power Button Problem

Hello. I just notice when I update the firmware to NF4, the power button of my note 3 has a problem.
Here is the scenario.
I turned off the phone, remove the battery then insert it back. Trying to turn on or boot my phone using the power button but no matter how I try to press still no luck. When I charge the phone, of course the battery icon is in display. I press the power button then that's the time it boots.
Anyone been experience like this? What is the solution? I already tried to reformat the phone but still the problem is there.
Thank you for the help. Thanks.
