After updating to android 7.1 I encountered a strange bug in my Nokia 3: occasionally the phone won't wake up when pressing the power button, the screen stays black no matter what. However, the phone is working, you can call it, etc. After being left alone for some time it can start working normally, then, after a while - stop responding again, and so on.
The problem appears to be in the automatic screen brightness adjustment function. In all cases, the screen stopped (or started) working only after the phone had been kept in darkness for some time (in a jeans pocket, or simply on a table at night). I switched off the automatic brightness adjustment, and now the problem is gone (haven't seen it for 3 days now).
I hope this information will help if anyone encounters this problem.
PS It was not particularly easy to track down this bug, I even took the phone to the shop where I bought it for repair. They replaced something in the phone, took them 3 weeks to do that, but the same day they gave it back to me - the screen went black again. Imagine my frustration!
I did a bit more testing and that's what I've found:
1) auto brightness has nothing to do with the black screen bug, apparently it was just a coincidence.
2) switching off intelligent power saving standby does not seem to be a solution either. I updated to the last update where this power saving option is no longer available, but the problem persists.
3) the bug seems to be somehow connected with the camera usage. I intentionally did some testing of it. When I reboot after the screen freeze, the phone can work normally for days without freezing (I did not wait more than 3 days though). However, if I take a shot, the screen freezes. It does not however freeze immediately, it can freeze 20 minutes after taking the shot, or a several hours later. In another thread ( Display doesn't turn on) user1506691753230 also reports having this black creen issue after taking a picture. I have not yet figured out what directly triggeres this bug, but I'm going to test a bit more.
Do you guys also experience this bug only after using the camera?
i have nokia 5 and i am facing this software problem,blank screen with sentence nokia flash problem i havent even downliaded a single malicious file,new device just one week over
Hi, I too have the same issue on my Nokia 3 Phone, i suspected "press power button twice for camera " and disabled that option, will update if problem persists
Hi Alexander - are you referring to "Adaptive Brightness" in Display menu ?
Yes, but it is not the source of the bug, as we figured out. Turning it off does not work.
When I had no black screens for several days after turning it off (as I report in the top post) - it must have been a coincidence. I probably simply did not use the camera then.
I have exactly the same problem. It is super annoying that the screen goes black in middle of video and you have to start searching the part you left off all over again. Problem has started only few days ago. Android 7.12. I have not been able to find any root cause for this issue. Nokia 5.
I think this is software issue. Nokia, please fix this as soon as possible!
On my Nokia 3 I have never seen this bug while the phone is in use - only when it is left alone for some time.
