i had my screen broken unfortunately. I received a replacement that i don't know if it is an official one, that was excellent until i put it to charge. The screen lightly flickers. I don't have an official charger and mine outputs 5v and 0.18A. when the phone is down the screen is ok. It flickers when i touch the metal to the side of the battery.

This happens even when minimal pressure which suggests a grounding issue? When non conductive materials touch the side - even if with a lot of pressure nothing happens. And finally, this happens only when charging. My phone is Samsung Galaxy J5 (2016).

EDIT 1: I can confirm it is a grounding issue because when i touch the metal surface with a metal connected to a GND, the flickering stops completely

EDIT 2: I went to the repair shop and got an official Samsung charger (5v, 1.55A). The flickering has almost vanished. You have to pay real close attention to see a very slight flickering when it charges and you touch the metal surface around the screen. Still no clue on what is happening.

  • Sounds like what you suspect but unless you change the charger and power point you are connected to one can't be sure. But flickering / ghost touches are attributed to grounding – beeshyams Jan 9 '18 at 15:37
  • tomorrow i will check with the official charger. what do you mean "power point"? do you think its solvable? is it a defect screen or a bad reassembly? – user1584421 Jan 9 '18 at 16:42
  • Power point = where you plug in the charger (try a different one since that could also have earth leak issues, unlikely though). I have no experience of changing screens so can't say and in any case such hardware issues are best left to competent people who have the skill and tools. I am only trying to rule out other things before that path of service centre – beeshyams Jan 9 '18 at 16:46
  • yes this happens in all power points with all (unoficial) chargers i have tried so far – user1584421 Jan 9 '18 at 16:51
  • To me it looks like a visit to service centre for a check and solution. Things can't be very different with official charger since you have tried multiple chargers – beeshyams Jan 9 '18 at 16:54
