[Q] "black screen of death" and first step to solution - Nexus 4 Q&A, Help & Troubleshooting

Hi there,
Many of you know that nexus 4 is experiencing random "black screen of death". What happens is that the phone freezes while in sleep (stand-by) for long time, for example over night. It is not a complete freeze, as the notification light keep blinking (if there are notifications); when you call the phone the caller hears a proper "ringing" tone (so the phone is not off), but the nexus 4 itself doesn't make any sounds. Alarms also don't sound, which makes Nexus 4 a horribly unreliable alarm clock.
The only way out of the freeze is holding the on/off button for 10 sec, which turns off the phone, and then holding it again for usual 1-2 sec to turn the phone back on.
What I discovered is that these freezes happen 1-3 times a week, but only if I have pattern password on lock screen. When I turn password off (so I have the "slide to unlock"), freezes are gone. Maybe this information will help others, or provide some insight to a complete solution to the problem? Does anybody have other experiences with black screen of death on their nexus 4?
Just a note, I have stock but rooted nexus 4. Internet reports that these problems happen on stock unrooted, stock rooted, custom roms, even on phones freshly out of factory reset with no apps installed.
Here are some threads talking about the problem:
Google Product forum
AndroidCentral Forums

I've always been on SlideToUnlock and mine has been doing that for some time since I started playing with custom roms (w/root)
What fixed it for me was to disable the PlayStore "Auto Update Apps".

Persistent Lag

I have a Nexus 4 and along with it, a pesky lag problem. My lockscreen consistently freezes when I go to turn on the screen. I'll press the lock button, the screen will come, and then when I press the lock to unlock the phone, it will freeze. I'll have to turn the screen off and then back on again to be able to unlock my phone.
I had CM10.1 on my phone and I thought this was the issue, so now I have a rooted stock, and still have this problem.
Any ideas as to why this is happening?
Do you have Touch Control (app) installed by any chance? It's known for freezing your screen every now and again (on one phone more regularly than others)
If you don't, I haven't heard of random freezes yet, but could be app related.

[Q] Screen off randomly

Hi all.
I'm facing a strange issue: my screen turns off randomly, everything else works (led, soft buttons,...) and when pressing the lock button i even hear the noise of the phone locking.
Normally when i unlock the phone the screen turns on ok, sometimes i need to repeat 2 times to get screen on, and while using the phone again the screen might turn off in 3 seconds or it might work of for several hours.
I'm attaching a log where a random screen of happens just two-three seconds after a random screen off and i would kindly request any dev to look at it and try to answer if it's a hard or ROM/kernel issue (actually i'm with crdroid rom and chronic kernel).
If it were a hard issue i've bootloader & knox ok for being able to reflash to any official rom but i'm a little scared about having a random screen off while flashing: i've no idea of how i should act if i fall in this situation.
Hope anybody might see the log and give me some light!!
Cheers all!!

Screen not turning on after phonecalls...

My phone has been temperamental lately. Sometimes when there is not enough light in the room, the screen will immediately turn off (I am aware that is supposed to be a feature to combat a false "knock on" while in your pocket - but this is far worse than that. even in dim light). I can also replicate a problem of having my screen NEVER turn back on. All I have to do is make a call, or call voicemail and its like the phone just locks up. cant do anything but hold power for 10 seconds. Ive booted into safemode to no avail.
Only thing left to do is factory reset... but im starting to think its physical issue caused by me dropping it
has anyone had similar problems?
Are you running stock or custom ROM? I've experienced, and heard of many other people having this problem on various 4.4 Roms. I've not had the issue when running stock however.

I've been having the same problems recently...so I was running it previously with stock + G2 Xposed, then I dropped it and the screen shattered. Some functionality was lost as you'd imagine, but it was all to do with the screen lacking sensitivity in places (what was left of it anyway). I got the screen replaced and then started having all these problems.
So for me, the screen will sometimes turn off as soon as I turn it on (this can be counteracted by spamming either volume button - not ideal, but it works). The screen will also sometimes turn black after making/receiving a phone call, and though I can still take the call, I can't turn the screen back on unless I either receive another call (this doesn't always work) or just reset the phone with the hard keys. I did a factory reset and this hasn't sorted the problem out at all. I've scoured the net for a solution and haven't come across anything as of yet...

Lock Screen won't turn off

Hi there. I'm currently having an issue with my S7 edge where the lock screen won't turn off after some time. The screen does turn off when I'm using the phone normally from the main screen after some time passes but it's just the lock screen I have issues with.
Whenever I charge my phone or just hit the power button once to see notifications on the lock screen, it'll just stay like that until the same time the main screen timeout configured time passes (5 minutes) and this is getting annoying and somewhat draining a little bit more of my battery. Previously it was working fine and the lock screen would turn off after around 10 seconds or so.
Has anyone faced any similar issues with their phones? I haven't tried a factory reset yet but I'd want that to be a last resort.
Clear Background apps.
It happens when you left some games or apps by pressing home button but it keeps running. Hope they will fix this soon.
Have you tried pressing that little button on the right side of the phone? That usually helps.
Yeah...I already tried that with no luck. Even tried uninstalling some recent apps in case one of them was cause but it didn't work either. Any other suggestions?
The issue isn't with turning the phone screen off by pressing the power button, it's the lock screen itself not turning off after a few seconds when it usually does.
I'm having the same problem, had good lock installed thought that may have been the problem but after uninstalling that I'm still having the same problem with samsungs oem lock screen. I too would like an answer or fix for this. also to note, in developer options the stay awake is off and no apps running in the background.
I am having this problem now also. The screen will lock, but the display stays on but dimmed. I can tap the screen and it will get bright. Now I must click the side button every time I set my phone down or the screen will drain the battery.
I'm facing exactly the same issue. When the screen is locked, it stays on for the same time confirmed to when its unlocked. For example, 1 minute, instead of 10-15 seconds.
Any workaround discovered for this?
Did anyone find a solution to this problem?
I thought that I might've been the only one! This problem only appeared on my phone after the Nougat update, and it's extremely annoying as I rely on notifications waking the screen for my main messaging app.

Screen won't turn off during phone calls

I use my phone a ton for calls , imagine that .
Lately when I put a call on speaker, the screen will not turn off. It will not time out and even if I press the power button to shut the screen off manually, it just comes right back on.
Has anyone else experienced this and if so have you been able to correct it?
p.s. this has only been happening in the past week or so and I can't think of anything I did or any updates that would have caused this.
Thanks
I'm experiencing this same thing. Tried multiple things and even did a hard reset and the issue still persists. Very annoying.
I found a workaround where if I come out of the phone app, then I can lock the screen.
got the same thing. i read something on AC( think it was) regarding the calendar notifications not allowing the screen to go dark too. i wake up, my phone is super hot if i have an all day appt with a notification. did yall find a fix to this? the other forum mentioned possible connection to samsung pay.
Having the same issue. The screen does not turn off when holding the phone to my ear or when I'm using bluetooth headset.
