I have bought S21 ultra and I face some issue while I open hotspot or USB tethering and after a while the connection of 4g drop from mobile all ( there is signal ) but no internet on mobile data .. but when I had a call the connection is back .. so anyone have a solution for that.
I am having the same issue. After about 5 minutes the connection drops. I can re-connect immediately no problem but again after a few minutes it drops.
