Slowly improving. Power save mode and 120hz WQHD, BLUETOOTH, LOCATION & SYNC on. And heard a lot of talk regarding this developer option improving battery life.

Hi, a while ago I changed the csc of my s21 ultra with the code *#272*IMEI# and it worked perfect, but I realized that I stopped receiving OTA updates and I have to be flashing the updates by odin, someone knows how to fix that ?? I changed the csc again with the code to the original but the same thing continues to happen. Greetings!
