Hi, I recently purchased Samsung M21 mobile, I want to change Frequency Band from 2.5ghz to 5ghz. I didnot find option at Connection> Wifi > Advance screen.
Very bad experience in such standard company smart mobile.
Not suggesting friend/relative to by this company mobile.
Kindly let me know if someone know about this. Many thanks in advance. Jayesh|+91-9924480540
