I am using the FP2, with up-to-date Android 7.1.2.
Since a few months, maybe since a system update (but I’m not sure of it), I experience problems with phone calls :
I cannot receive any call : callers are directed toward my voice mailbox without any ring on my phone ; I’m just aware of such a call through receiving the operator SMS telling me about the missed call.
I cannot phone anyone, any number, even my mailbox : the call app tries to start the call, but without success, although I can see the network changing from 4G to 3G during this operation.
Please note that
my phone network is configured for 4G/3G/2G, and mobile data work correctly.
I can enable in/out calls through setting the network to 2G only, thus losing the mobile data functionality ; so I currently manage to use the FP2 through changing from one setting to the other and back again.
the problem occurs in any place, in France, northern, southern, … , or in London, …
I tested my SIM card on another phone : in/out calls were OK, under 4G/3G/2G setting.
I tested my FP2 with another SIM card : same problems occur.
I only use slot 2 of my FP2 since slot 1 never worked correctly (since the FP2 purchase).
If you have excluded SIM as a problem, you would need to exclude “software issue” upon device which would then point to “hardware issue” upon motherboard SIM holder unfortunately. As price of pre-owned FP2 now falling due to imminent delivery of FP3 I doubt it is viable to consider replacement of motherboard now, especially as device would have to be sent back to Fairphone for repair.
I guess I could perform the data backup and system restore ; I’m used to get my personal data to computer through usb ; but I’ve been reluctant to let all stuff go out to google as far as I can avoid it… and actually I doubt the sync services will backup all installed apps, especially those installed through F-Droid, will they ?
I guess the alternative would be the hard way : reinstalling and configuring each app by myself, or is there anything in between ?
If ever the issue came through a system update, how to avoid it to happen again after system restore ? system updates will occur again, won’t they ?
I will also look out the angels community around Paris.
