My Note 8 today received the security update for July. Once installed, phone updated and restarted however now does not recognise SIM cards. Its only shwoing 'No SIM card- Emergency calls only' on lock screen. Under the Settings > Connections, the 'SIM Card Manager' option is not working, apparently corrupted by the upadte patch.
Has anyone faced this issue?, If any solution other than factory reset, please share.
appreciate your quick response, however even safe mode doesn't help as the update patch has corrupted the internal system app 'SIM card manager'
I have even tried clear cache 3 times, but of no use.
