3 separate phones with the same issue
I had a galaxy A12 for a year and it started acting up when the charger was plugged in. It would light up and indicate it was charging then light up and show it wasn't charging. It would do this over and over till it wouldn't recognize it was plugged in anymore. I was able to replace that one and after about 2 weeks the new one started doing the same thing. I immediately replaced that one with what I currently have. I've had it about 3 weeks and it is now doing the same thing as the other 2 phones. I've tried different chargers with no luck. The charging port is clean and free of debris. Why do I keep having these problems even with new phones?
