Review on Factory Unlocked Samsung Galaxy S21 Ultra 5G Android Phone with 128GB Storage by Jhalak Jhalak ᠌

Since October 21, we have been sitting and waiting for a new firmware. March already. After the firmware on Android 12 (and you can’t roll back to the 11th without losing the knox and spay folder), the network constantly falls off and does not connect back. All advice from forums does not help. The use of only 2/3 mode helps a little. Used different operators, everywhere the same. If it loses the network (at the same time it shows that everything is OK), then it does not find it back itself, it is necessary to re-plug the airplane mode. It is best played when exiting the subway or in the subway itself.
