Getting low signal in my new samsung M21 while the other phones are getting full signal. Found several posts regarding this issue but samsung has no headache to solve this. Really disappointing issue for a brand like this.
To resolve network issue please follow below given steps:-
1. Check network operators and select automatically (Settings> Connections> Mobile Network>Network operator> select automatically > Tap on OK > Registered on network).
2. Reset the device: settings >General Management > Tap on Reset. Note: Before reset make sure to have back up of the data via Smart Switch Mobile App (Install Smart Switch App > Open > Click on Memory Card Icon >Back Up option > Choose the data for Back up > Back Up).
If the issue still persist, kindly register your concern in Samsung Members app (Samsung Members app > Get help > Feedback > Error report/ask question). Note: Please send device log files within 15 minutes of issue occurrence along with the exact issue details.
