WiFi frequency low

[Jishnumuraleedharan]

In s21 ultra the WiFi frequency very low because I was using s9plus before comparing to that s21 ultra WiFi frequency is low

When we are using through wifi , some time we are used to go out (means go somewhere very near ) it will automatically off

Is your phone's power save option on?
As the power saving option limits the phone performance to last the battery time longer.
