My FP does not start up. I see the Fairphone logo, but there is nothing more I can do. I waiting for the battery to run out, charged it, took the battery out and put it back in again, tried to switch it off and on again several times… But nothing…
for a few minutes, everything seems to go a usual, but then I make one
phone call, to my voicemail who’s full of messages by now, and after half a
message, the screen goes black again and the phone is dead once again…
If the screen doesn’t just go black but the phone crashes there could be many reasons for that. Although it’s not the exact same issue, troubleshooting is about the same as for random reboots, so please check this support article and the first post here.
