I have Nexus 7 32GB Wifi. I have rooted it last week, but hasn't installed any custom recovery or ROM. The one problem i have noticed after that is , sometimes i have to press power button twice to wake up the tablet, only then my unlock screen comes up. I tried waiting few seconds after pressing power button once, but the screen will not turn on, i had to press power button second time. Any idea?
Thanks

The title says it all. I did a back up and flashed the rom. It worked well after the first boot but the Google apps was FC so I reboot to flash the gapps file. However, after shut down the kindle it just wont turn on. When I press the power button the green light appears for 3 seconds and it off again. What can I do ?
Edit: Now when I press the power button nothing happen :|
maybe charging it with the wall charger for some hours ...
Try holding down in the power button for like 20 seconds them turn on

I had this issue and thought I toasted it, negative.
Check to see if screen is still lit, if so tap power, screen should turn off. Wait about a minute then press and hold the power button for 20 seconds.
By that time should still be off, then after you let it go tap the power and should boot right up.
Not sure whats causing this but a minor glitch in the matrix, no biggie. Still very much useable after install of gapps.

Thanks I was able to turn it back one after a few tries
It seems this rom doesn't actually shut down. When I select the shutdown option the back light remains on and I have to force it off with the 20 button press.
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
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?
Sent from my Nexus 4 using xda premium
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

When i unlock my nexus 4 and hold power button nothing happens and when i leave it it just locks again, i don't think it's an hardware problem because my power button works fine in locking and unlocking action...what can i do?

Have you held it for 10+ seconds?

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
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.
