I hear people struggle with some of these, but do others also face all of them? A quick run-down of the three problems:
Almost several times(!) a day my phone restarts, after which I have to use my PIN (regular, not SIM) to unlock again, Then the phone starts loading apps and what not, which can range from quite quickly to very long. Once my phone got stuck in this process, after which I had to remove the battery to boot it again.
They started recurring again after the Android 10 upgrade. I’ve already had to deal with these severe issues during the first six months this phone was released, after which the frequency of which these happened dropped a lot (I don’t think there was a time where they were non-existent). It seems like they are back now in full force.
Secondly, sometimes my phone will not unlock. Instead, the phone screen will remain black when clicking the unlock button. After leaving the phone untouched for a while (~1min), pressing the unlock button will bring me to the initial state of the phone as I wanted to lock it (bypassing the lock screen). This makes me feel like the phone was never locked from the start (and that the problem lies there). Also, I associate this problem with me using the phone for media consumption (e.g. watching video streams), so it might be related with that as well. I have had this issue from the start.
Lastly, at times when calling someone or receiving a call from someone, the call audio seems to be muted. However, I am able to use the volume controls, but they won’t have any effect. A lot of times calling back or calling again will do the trick, but some times the issue will persist (which is as infuriating as it sounds). WhatsApp voice calls are not affected by this, which is what I use as second workaround. I have had this issue on and off from the start as well.
Having heard the reputation of early FP2, I knew what I was getting into, but I didn’t realise the extent of the problems. There were other issues at the launch of FP3 (e.g. headphone audio bug - which I contacted support for), but they have been resolved. It is why I held off on posting earlier, but with the recent uptick in severity (which coincides with the Android 10 update) I decided to post for mostly documentation’s sake. It might be good to know that there are still FP users struggling with bugs that have persisted from the start (albeit in varying frequency).
TL;DR: Have been experiencing random reboots, a lock/unlock problem and muted call audio. This was always the case, but with the Android 10 update frequency of said problems have increased.
