S21 ultra Network issues

My phone has been struggling to maintain a connection to network since late last year. Signal drops in and out randomly at home while other devices are fine.

 

I have tried my sim card in other phones,

 

Factory reset, reset network settings, tried to use e-sim, and all other common solutions. 

 

Nothing works. When signal is lost, sometimes turning flight mode on and off will bring signal back for a while.

 

This happens everywhere from home to town, and I live in a city with 5g available. 

 

Something needs to be done about this. Very disappointed as I have owned multiple galaxy S line phones since the s2. 

 

I would be very wary purchasing anything from Samsung in the future considering they have yet to acknowledge this issue despite the many threads describing the same issue.

Same here , S9 no problems at all on 4G .. lucky if I get a 5g or stable 4g on my s21 ultra .. they've discontinued s21 ultra probably due to the persistent issues we are all having.. I'm jumping ship - feel totally let down with my S21 ultra and Samsung won't have any of it!!

And I'm already one of those people with a non-working phone. After updating to Android 13. My phone only works in 2G mode. I tried everything possible but there is no fix. I read many comments with such a problem, there is no solution.
