IPhone 6 screen is very dark and keeps flickering, happened after running and got sweat on it?

I was running and I had my phone in an arm band. In the middle of my run my music just stopped and when I took my phone out half the screen was black and then it just shut off completely. That was 2 days ago. As soon as it happened I put it in a bag of rice, about 30 minutes after the phone was very very very hot so I took it out. I took it to the Verizon store and they took a flash light and looked in the bottom and said it didn't look water damaged. I don't have insurance so they wouldn't help me further. I live in Potsdam NY and the closest Apple store is over 3 hours away. Today when I plugged the phone into my computer to put the pictures on my computer the phone lit up and it was doing the whole half the screen is dark thing again… But now it won't stay lit up at all you can barely even tell the screen is on its so dark, it occasionally flickers bright again and then just goes back to black. Is there anything I can do to fix this?

  • Why do I do this? I'm very very very tired yet I don't want to sleep? I want to sleep because I'm practically blinking and bobbing my head side to side like a drunken man but I just don't want to sleep. I watch tv or go on Facebook or play on my iPhone. And I'm starting to get dark circles. And as a guy I don't wear. Concealer or whatever
  • Screen on iPhone 4S is flickering blurry and faded? I had a new screen fitted on my phone 2 days ago and it has just started flickering and gone blurry around the edge of the screen. It's got lines across the screen as well. What could it be?
  • My phone keeps flickering black? So I have an iPhone 6s and randomly, it'll just start flickering to a black screen. Sometimes there are lines running down the phone and you can see some the home page and sometimes it just goes to completely black. I've dropped my phone many times and I think it might be because of that? I end up having to shut down my phone in order for it to start working properly. This happens at least 2 times a day. What should I do?
  • My iphone screen is very dark, but if I look very close, I see the apps slightly? My iphone screen is very dark but I still see the buttons slightly, but I have to look very closely in order to. It is definitely not the brightness, because the brightness is set to 100% and its way too dark anyway. I tried restoring my phone and turning it on and off, but nothing is working. Please help. What do I do? I literally threw it out of anger and its fixed.
