screen temporarily won't turn on - Nexus 5 Q&A, Help & Troubleshooting

I've run into this issue with a few ROMs on this phone now, notably Blisspop but a few others as well. When I turn the screen off or it times out I'll have to do a hard reset in order to get the screen back on, on occaison. I's not the end of the world, but it's kind of annoying. Has anyone else had this issue?

Need help with fuze screen!!!

When i upgraded to the tilt 2 I gave my fuze to my fiance. It was working great until a few days ago. she was having some issues with the touch screen regestering her touches. I fixed that with a hard reset. She was running the stock ATT rom at the time. after the hard reset it seemed to work better, but there was another problem i noticed afterwards.... the backlight for the screen does not turn off. whe i hit the power button to turn the screen off, the screen goes black, but the backlight stays on. I tried messing with the power settings, but that didn't work, so i tried the next option which was to do a clean install of a custom rom. I flashed the most current energy rom. did another hard reset after the flash, and still the backlight will not turn off. she is going through batteries real fast and i cant figure out what the cause is.... Afte hard resetting and re flashing, i can only assume this is a hardware issue. however I am out of warranty. I would really like to find a way to get this fixed, so she can use the phone. Unfortunately, if I can not fix theis problem SHE IS GOING TO MAKE ME BUY HER AN IPHONE!!!!!. please help me avoid turning her over to the dark side.
thanks

Screen Not Timing Out...I know why, but need help.

I have identified the culprit, but I have not been able to find a solution.
As I said, my screen will not timeout. I have to manually hit the lock button to turn the screen off. Also, the softkeys stay lit. I started going through app settings, etc. No luck. I began to notice after reboots and battery pulls that it only started occuring after I entered mode (*#0011#) to fix the wifi disconnect issue.
After doing that, the screen will no longer timeout. So, at this point, I either have to deal with wifi turning off and on randomly, or a screen that won't go dark on its own.
Can anyone help?

[Q] [SPH-D720] Back light appears to randomly shutoff

Over this past week the back light for my Nexus S 4G appears to randomly shut off. Right now it has happened about 5 times and when I need to use it right then, preventing me from just stopping to investigate what may be causing this. The screen still comes on allowing me to quickly unlock using the pattern and then restart by holding down the power button. The one time I was able to investigate a little I was navigating into the settings menu when the screen just went blank. I pressed the power button a few times and could see the hardware buttons below lighting up as if the screen was on but that was it.
I'm currently running Slim Bean (Android 4.2.1) Beta and will be trying another rom but wanted to see if anyone else may have encountered this issue before I bring it up with that thread.
Yeah experienced this too in most 4.2 ROMs that I've tried. Some people say it's a bug with the auto- brightness settings but I don't buy it since I don't really use auto-brightness but still get the error. I'm back to 4.1.2
Glad to hear. I was becoming worried I had some hardware that was failing.
I will turn auto brightness off and see how it goes.
Thank you
So it has happened quite a bit since my last post. Even with auto-brightness turned off. I'm blaming this bug for my alarm not continuing after I snoozed it a few times. (I know they are unrelated but its just really annoying).
It happened again about ten minutes ago and I managed to output a bug report feature on 4.2.1. Not sure if it is of any use to anyone. Message me if you would like it.

Screen is constantly locking for no reason, is my light sensor busted?

Hi all,
When I'm using my month old Nexus 5 it will just randomly kick me back to the lock screen, sometimes I can just unlock it and keep on trucking but sometimes it will just immediately lock again or it will work for a couple of seconds and then re-lock. Once its in this state even a reboot doesn't always help and about the only thing I can do is get into recovery mode and re-flash it again. I used the Sensor Box app and have noticed that the light sensor is always reading zero, and I'm not sure if this is part of the issue?
This was happening on the PA Alpha, Stock 5.0.1 and since I was still having the issue I flashed back to 4.4.
The weird thing is that my phone had been fine for the 3 weeks or so I had it before hand. I flashed lollipop on it less than an hour after I took it out of the box and it had been running smoothly up until yesterday.
So a few questions:
Is there anything I can try to fix ir?
Can I use debugging to see what is causing the screen to lock?
Is this likely to be a hardware issue?
If it is, is there anything I will need to do to make sure I keep my warranty?
Any help is very much appreciated.
Bump with some other information:
I don't think its the light sensor, I tried using the phone in a pitch black room last night and the same thing was constantly happening, there was something else odd happening though.
From the restore of 4.4 I was on the "Select language" screen, whilst I could swipe and roll the various language options up and down the moment I presses "Next" the phone locked, if I left the phone on this screen eventually the screen would automatically lock and then it would keep locking itself constantly again.
Also, just for total clarification by "lock" I meaning "return to lock screen" not freeze up and become unresponsive.

[Q] Proximity sensor doesn't seem to work?

When i receive a phone call the screen turns off when i put it to my face, but when i move it away the screen never turns back on. I can't hang up the phone i end up having to restart the whole damn thing. Anyone else experienced this?
Yes I have the same issue going on now. I'm trying to see if there's some kind of manual over-ride or if the phone can cycle the screen on and off with just the side button / power button click alone. Would be fantastically helpful.
Mine is not dirty, it is broken, I have tried cleaning it with no avail.
