My two-year-old FP is exhibiting some strange behaviour:
- It reboots on its own, both while in use and while idle (I’ll take it out of my pocket and find it’s in the process of rebooting). This happens sometimes several times in quick succession, sometimes not at all for a few days.
- It sometimes doesn’t react to the power button when the screen is off. Waiting a few seconds sometimes does the trick and the phone wakes up again, but at other times the only thing that helps is removing the battery and switching the phone back on.
- In the latter case above, the reboot can sometimes take as long as 15 minutes, during which the phone heats up considerably.
After a spontaneous reboot, the battery usage history is sometimes reset. But it also happens, when I check the battery usage history without having noticed anything strange, that there are short or long gaps. The long one in attachment 1 and the shorter one in attachment 2 both happened when I was sleeping, so the phone had not been used for a few hours. And attachment 3… ski jumping, anyone?
The unresponsiveness started happening maybe six months ago - then the original battery bloated in September, and I assumed the symptom was related to the battery. But now all these things are happening more and more often with the brand-new battery.
Needless to say, this is quite inconvenient, and I’m a bit worried about wake-up alarms and other situations when it’s important to have a working phone. I realise the symptoms are vague, but is anyone experiencing anything similar? Any tips?
