Hi guys, I just want to ask how to fix my Samsung Galaxy S4 GT-I9505. After booting up the phone, a notification shows on the status bar that the phone is in docking mode even though it is not. But after a few minutes the notification will disappear. Still, I am worried because it is not normal and I think something must be wrong with it. I'm using original charger and usb cable when charging or connecting to PC. Can you help me? Thanks.
