HI there I have changed the chargin flex in samsung galaxy S6 but now afterward so I cannot charge the phone via USB port, when I plug in the charger, it shows that the phone is charging but the chargin procent does not go up but also it goes down. What can it depend? Do I need to change the charge flex again? Thanks in advance for all answer and solutions Sincerely
Could be charging chip going faulty but try another charging port flex. I’m kinda surprised you managed to replace the flex as almost everyone damages the LCD. The best way to do it is to replace the charger port with micro soldering without needing to remove the port or lift up the screen.
