Same for me. Except most times the screen has not even gone blank, it just froze in place. Then it doesn’t respond to any touch and no apps update. Eg my alarm was on snooze but did not ring
@rachels42 Do you use the stock image or a self-compiled one? Mine is self-compiled, but I vaguely remember having the issue with the stock image as well.
Vivia, sorry, what do you mean? The stock image of what exactly?
Of the Fairphone. If you didn’t flash a different image, you have the stock one. If you don’t know what I’m talking about, you have the stock one. 
Ah, just googled, and, no, I didn’t flash a different image 
As long as a problem can’t be reproduced by many users we usually don’t consider it a bug. Also you’ll usually get help faster in the help category.
You could try a hard reset, but be aware that it deletes all your data.
what happens if you push the power button in to lock the screen and then unlock it again, anything?
Hi, just wanted to state that same happened to me twice within the last 3 days, in both cases I wasn’t actively using the phone - just found it to be not responding to anything when I picked it up again and the screen remaining black.
Maybe it could have been related to ongoing app installations? I think that was common for the 2 times in my case.
After all I had to remove the battery and then I could start the phone again.
Besides also random resets happened to me a few times already (e.g. found it asking for SIM pin when I picked it up this morning, which only happens after a reboot)

Hi,
my FP2 crashed / restarted itself today 5 times (within 3hours range).
Id never happend before and started today just right after I switched the 4G/3G mode to my second SIM Card.
After switching it back to the “old” SIM card it worked fine again.
So in my case its definitely caused by one of my SIM cards and the data transfer with 4G/3G.

How old are your SIM cards?
For crash analysis, I would again suggest to plug the phone in ADB, start an adb logcat and wait for or make the crash happen. If you post here the last log lines just before the crash, some geek on the forum might be able to get a clue about what is happening.
Hi all!
I just registered in the Forums to look about this issue, and saw that is happening to other people as well.
I’m happy with my user experience with the FP2, except that it happened to me exactly the same problem described in this thread, two times in 3 days. In both cases, the phone were just laying on the table next to me. I took it and saw it is unresponsive, screen pitch black, no feedback from any button press.
Second time I connected the phone to the computer via USB cable, to check if it was just a screen issue, but the phone went undetected by the computer. So I guess it just shut off.
Only after remove the battery, and then put it again in place, I was able to switch the phone back on.
I have stock ROM r4275.1_FP2_gms36_1.1.7

@Jon1 when the screen freezes it freezes, so I can’t lock the screen. I have at least found I can restart the phone by holding down the power button for about 10 seconds. When it restarts it works fine until it crashes again. It has at least only crashed once in the last week

@jaymanu just googled and is an adb an android debug bridge? If so, does the phone have to be plugged into anything, or can it just be running in the background. I can’t predictably say when my phone will crash and it might be a few days before it crashes again
The SIM card that works fine: 1 month
The one that is not working: 1 year
There is a slight possibility that the SIM card of 1 year old is to old.
Perhaps you could try a SIM card from somebody else in your phone to see if it’s really your SIM card that’s having a problem.
@rachels42 yes, for ADB you need to have your phone plugged to your computer with USB.
Then you install ADB software on the computer side, and enable USB debugging on the phone.
You can do a logcat to display the system log, which is the journal where we could look for hints about what caused the crash.
It might work if you logcat right after the crash, if the crash is not too much severe, but it would be more accurate if you were already logging while the crash happens.
@jaymanu I’ll see what I can do. Hopefully will have some time this weekend to work out hot to install ADB and display the system log. Then hopefully will have a crash when I’m by my laptop. Do you have any idea of the maximum time window I would have after a crash to do the log?
Well if you remove your battery, unfortunately it will reset the phone and delete its internal log.
You might anyway try to use ADB on your phone while its in the frozen state. There’s a (small) possibility that the underlying system could still respond while the user interface is crashed.
Hmm, if I manage to restart by doing a long press on the power button does that also reset the phone / delete the log?
