Galaxy J3 2016 appears to be dead, but makes charging sound
Hello. So a good friend of my father, gave him his old J3 2016.
He said that it had a problem. So my father gave it to me to take a look, and the phone appeared to be dead. No signs of life whatsoever. But when i plugged it to my charger, the phone make the classic Samsung charging sound! I left it to charge for hours and came back, but it was still dead. My PC recognizes it, and by right clicking on it, i can see that the battery is 100% charged, the firmware version, and the serial number. Kies 3 recognizes it too, but it claims that the phone is locked. The phone is still looking like it's dead. No matter what i try. (Yes i tried to boot in recovery and download mode, nothing)
I also noticed that when i hold the home and power buttons, i can hear the "screenshot sound".
It's looking more and more like a dead screen, but shouldnt the touch buttons light up in that case?
Shouldn't the phone vibrate on boot?
