my phone was once fallen down now it has a problem with its wifi. Wifi keeps on disconnecting. Wht to do
it was once fallen down. And after that it has a problem in connecting with the wifi like it only catches 1 signal of the wifi and when the screen is off it disconnected and when the screen is on it ctches the signal. I tried to check the sim card and after that it worked and now it still has the same problem.
