I'm replying to my own post, in case it serves anyone: this bug on the Fairphone 2 is with the newer Fairphone camera module only. So I put the first generation camera module inside (I still had it in a drawer somewhere) and now the phone turns off fine. I don't care much about camera quality on this device anyway.
Hmm ... so if that APN is no longer in the file, then maybe it is not matching the "3" in the name field and so it defaults to what the provider or sim card sets? (I am assuming that is what it uses to match ... ) Sorry, not sure what to suggest from here ... ??
@tim The Halium 7.1 is in worse state then the current "legacy" port and it doesn't have stable releases (yet?). Last time I checked the camera didn't work and I don't think much work has been done on it since. I didn't have to install Android when switching from one port to the other. If the instructions don't say you should, I expect it's not necessary, but I could be wrong ofc.
The phone was stuck at the boot splash.
Get to recovery mode and then run the installer.
The installer says 'Cleaning up' , 'Erasing cache partition'.
Put it back in recovery mode.
Click continue on installer.
@jezek I have FP2 on Stable channel (so 5.1). I took the charger out yesterday evening to test, it's now a bit over 50%. Wifi was on. I didn't use it much, mostly looking at time occasionally and a bit of web browsing, but not much (maybe couple of minutes total).
Two weekends ago I managed to drain the battery in an hour or so I think, but I was constantly using the camera, so that's prob expected.
So yes, I'd say it's over 24h battery lifetime (assuming "normal" usage).
Hello, I have solved because the connection problems did not come from the smartphone but from the operator.
A website that monitors the performance of operators on the internet confirmed what I said.
