Can't turn off my device

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

Nexus 7 (2012) won't start

My Nexus 7 won't start...
It was running the 4.3 update, after the update it restarted, google logo was visible on screen for 20+ minutes then it turned off and after this would not start.
I tried leaving it in charger over night, I tried holding power button, tried holding power button with volume up, with volume down, and with up and down.
Nothing...
Anyone experience this?

Phone crahsed and now wont do anything [complete brick]

I was using my phone (43% battery) listening to music using the castbox podcast app when suddenly the music stopped and my phone completely froze, nothing worked not even stand by, i held down the power button to restart it but it just turned off and would not turn on again, i then left it and after around 10 minutes i see it has turned on, to a white google logo with a grey background (never seen that before) i hold down the power button again to try and restart it but it then just turned off again and wouldnt do anything regardless of what buttons i pressed (power/ power + volume up/down) i have plugged it in, still nothing, and nothing when pressing buttons while plugged in.
any one got any idea what could be wrong or how i could fix this?

Welcome new XDA member.... first post? Many threads on this topic. Have you held the power button down by itself for several minutes? Were you having ANY battery issues leading up to this? Can you boot to Recovery? Are you running TWRP?

6T Will not turn on

I was updating the apps on my phone and did a reboot. The device powered off and now I can't get it to turn on. I tried holding down the power button for 20 seconds but nothing. I have it plugged into a USB C cable now. I tried holding the power button and each of the volume buttons and nothing. Does anyone else have any suggestions.

yeah call oneplus and get a new replacement coming

Hold power + volume up. I had the same issue yesterday.

Thank you so much! I tried it before but I guess I was not holding it long enough.

Why does it happen.

I was having that problem too and remedied it by just pressing and holding random buttons down for random periods of time lol. Sorry it's not more precise. Eventually I had the power button held down with the volume up and it ended up turning on. Was down for a good like 2-5 min though with absolutely no signs of turning on.
Was only getting that problem after I selected oem unlock from dev options menu.
When it did turn back on, I powered down completely and held vol down with power to go into recovery and selected fastboot from that menu.

Yeah, thats what happened to me as well holding both Vol up and down with power. Now I either do vol up with power or vol down with power... never both haha. But I don't think vol up with power does anything.

for whoever has this issue and needs to see this, my steps to cut it back on (finally):
1. let it sit on the charger for like 5-10 minutes
2. unplug let sit again for a few minutes
3. pressed power and both volume buttons till i felt a buzz and it cut right on.
