Following the replacement of the bottom module last December (see earlier thread ) my FP2 was returned to me with a rigid back plastic cover which I’m unable to remove. Up till today I haven’t needed to remove it, as I haven’t had occasion to reboot by taking the battery out and putting it back.
This morning I was about to catch a train using a pre-booked mobile ticket. At the ticket gates I attempted to activate my ticket by going into the app (Chiltern Railways, FYI) . Unfortunately the app was very slow to retrieve the booking. After five minutes of watching it spin I tried rebooting, only for the FP2 to freeze on the “FAIRPHONE … POWERED BY ANDROID” screen. I desperately tried to remove the back cover to take the battery out but I couldn’t shift it. The phone remained in this sorry state for over two hours, until I charged it from a wall socket at home (despite an earlier attempt to to charge it from a socket on the train). In the meantime I had no option but to buy another ticket.
What caused this? I don’t think it was an issue with logging into the app, because I’d done that the night before and my password was stored. Immediately prior to the freeze the battery level was at 55% and the phone was attached to a power bank which had been charged overnight.
Is this the first symptom of a problem which could get much, much worse, like my charging problems of last year?
