Fp3+ turned off with no reason & refuse to turn on or charging

[Selandus]

Hmmm… sounds like we’ve experienced the same problem almost at the same time…

FP3+ suddenly freezes and switches off

Today my FP3+ (3,5 yo) suddenly switched off in my pocket. Tried to turn it on again, no response. Plugged in charger, no response. Pulled the battery and put in back in, no response. Plugged in the charger again, and suddenly there was a vibration. Few secconds later, there was a response to the on/off switch as well: the phone was starting up again. Battery was charged to 65%. It worked for a minute or so, then the screen froze but stayed lit at first. Few seconds later it turned black again. …

No solution yet.
