my friend have charging issues, he is saying that he can't use the phone while it's plugged into a socket, symptoms: phone doesn't work properly, lets say he's swiping the screen but nothing happens or something looks like to work but it doesn't. The phone is stock not rooted. When charging from USB it doesn't occur.
P.S. Charger is not original, specs: 100-240v - 50-60hz 0.15A output 5.0V 1.0A, thanks.
