Hello, first post here. My phone either displays a completely black screen, flickers, or displays a single green line in the middle. And I know it's on, I can hear the jingle when it turns on or when I get a text, and the buttons even light up. I hadn't done anything to my phone- didn't attempt to root it, didn't download any new apps for a while, nothing. It's been dropped a few times in the past but it came out okay with no issues since it had a cover on it. Other than that I've treated my phone with care. Any assistance? Is there a way to fix this or is this phone done for? Thanks in advance.
