My Galaxy J2 was running fineuntil about 3 months ago. After that point however my problems only increased.It started with the screen flickering at low brightness settings ( which I easily fixed with a Play Store application) but now recently I’ve been experiencing a problem where, whether my phone turns off byitself or by me clicking the Power Button, the screen flickers. But it stays black. At first, this problem was minor and after a few touches of the Power Button it would turn on. But as times gone on it has only gotten worse. It’s come tothe point now where I’ve removed my battery 5 times in one night to restart it just once.Both the volume and the homekey and also the touch screen work. My problem
