My Galaxy Tab7 is loosing wifi signal arounf 30 min after connection and move back to 4G network without any notice.
Then it cannot find available wifi network at all.
I brought this to the shop four times offering solutions such as software reset, update, remove the sd card and repairing the mail board.
However everything is still the same.
It is frustrating.
Please help me.
is this happening with just your own WiFi network at home, or all WiFi networks?
