Samsunglarry, yes am using the original charger. When i plug it in.. it pops up on screen as fast charging.. then after a second it changes back to regular charging. That happens every time i charge the phone
Do you experience these symptoms if you try to charge your device in safe mode?
Are you talking about the wireless charging? Then maybe go to settings > advanced > accessories and turn on the fast wireless charging.
If it is the cable, check if it is the original cable and adapter
