Hi, My Phone (galaxy A8 (2018) Duos 32 Gb) says no sim card inserted, this happens about once a day, but can go for as long as 2 days. I've tried different SIM configurations (1 SIM, 2 SIMs, different carriers...). This also happened before and after Oreo update. I've tried wiping cache partition, factory reset. It happens also under safe mode. When I restart the phone it works Ok until it happens again. Is this happing to anyone else and do you know a solution?
