Update s21 5g

After update, phone refreshing sim card during the conversation, loosing signal and Internet connection, so I have to call again... I did soft reset, doesn't help, I checked sim card on another device's, and working fine. Anyone got the same problem ?

Yup, same issue iv been having now for 2 months now there's no fix at the moment iv hear other people saying it's a new mother board I'm book in tomorrow at a samsung centre to see what they can do. Iv take screen recordings as well of the issue. I'd do the same if I where you.

Reset network settings once, search at Settings keyword "Reset". You won't lose your data or registered phone numbers. If your issue is solved, please accept my comment as solution by clicking at 3 dots on my comment😃

When device is loosing connection, I receiving message "you lost connection becouse offline mode/plain mode is on" something like this

What about factory reset? This is the only way then🙁

[Kowal4]

Phone loosing signal and ending Phone call

[Kowal4]

"Connection terminated because offline mode is on" something like this

@Kowal4: When you receive the notification, can you see a plane symbol in your Status Bar at the top of the screen to indicate that Flight Mode has been enabled (Settings > Connections > Flight Mode)? If you have 2 SIM's inserted, is the issue occurring on both SIMs? 

[Kowal4]

No, I don't see plane symbol, just lost connection, yes I have got 2 sims and issiue is on both of them on same time
