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.

I am in the UK 🇬🇧 and I experience the same on my S21 Ultra. My network band is constantly set to 3G as this is the only band with a near stable connection. Every update I look forward to it being resolved but it's been a lingering issue like you said with the Samsung S21 series and nothing has been done about it.

Could check for 'carrier services' by google under Google store and see if there is an update for it.

I signed up for it's beta and so keep getting updates now and then.

Whosetheboss in one video suggests to put your phone on airplane mode and back on after while so the phone can co nect back to the closest strongest tower if you have problems like that.
So worth a try.

Works temporarily sometimes, then loses connection again. Sometimes goes from full bars to none without even moving.

Any mods from Samsung care to chime in?
