After updating my S21 Ultra to one ui 7 android 15 , I have a problem with the network connection.

The network is completely disconnecting and goes into emergency mode, or it loses the antenna altogether, and I need to restart my phone every time to be able to connect to the network again.

Mujibar stop saying that it is a carrier issue. I thought it was at first and I even changed carriers. Places where I normally have good service don't work at all anymore. Samsung is rolling this update out on purpose to "force" us to upgrade to a newer model.

The network is completely disconnecting and goes into emergency mode, or it loses the antenna altogether. Places were I normally have good connection are now GONE. I also keep getting dropped calls on the road. This is a VERY BAD UPDATE by SAMSUNG. I think a CLASS ACTION LAWSUIT is needed.
