I have a Samsung galaxy s10 SM-G973F, android version 9 kernel version 4.14.85-17063867
I suddenly stopped being able to receive calls, even though I could make calls, I still has full signal bars. I restarted my phone and there was no sim cards detected, no signal.
I tired to open sim card manager in settings but it showed only a blank black screen - and then an error messasge com.android.phone has stopped working.
I looked in about phone - and the IMEI information was all unknown despite previously having been there.
I am still able to connect to wifi, bluetooth etc. My samsung account still connects.
I have already tried:
-removing and replacing two different sim card (which work perfectly in my samsung S6 tablet)
-using a new sim card (which again works in other phones)
-Resetting network connection settings
-Wiping partition (multiple times)
-Booting into safe mode - no difference
-Factory resetting the phone - no difference.
I notice that this same problem occured in many Note 8s after a July 2020 update and it was a samsung software issue. There is fix for this issue but only for the Note 8.
However there isn't a recovery for S10,
Please can someone help me with this issue? Is there some way of recovering my phone.
