Data drop to E

[GameSky]

After new upgrade to oneui 4.0.. 

Switching off wifi will cause data lost and drop to Edge, sometime even automatically drop to Edge for no reason

Same for my s21+, battery drain tremendous fast, network keep dropping especially for sim 2.

Har, now I notice not only sim 2, but sim 1 also same, data keep dropping.

Just compared with my spare xiaomi mi 10t... consistent 4g+ without any drop

while on my s21+ android 12 connection sometime will drop to Edge not to mention some apps crashing and sometime causing the phone to reboot itself.

wonder if can downgrade to oneui3.1, this time upgrade more likely downgrade.

also battery drain seems higher as well

@Samsung, please fix this as soonest as I missed so many important message and email since the Network keep dropping and impacted my works as well.

Never has proper QA is it? Always 1st major release got issue.
