Before the weekend, I sent this question: https://forum.fairphone.com/t/fp2-keeps-rebooting-every-2-mins/28324. Paul replied with some hints that I did not have time yet to try out - because I was out for the weekend.
The funny thing was that the entire weekend, my phone did not crash once. However, now that I am back home again, it almost immediately started crashing again...
I've tried using wifi and turning wifi off - that makes no difference. I cannot think of other things different at the hotel and back at home.
Anyone who can make an educated guess?
