BACKLIGHT NOT WORKING?!
So I have an 16gb iPhone 6, running IOS 10.2.1 and just yesterday I was using it perfectly fine, I put it in my pocket, but a couple minutes later when I took it out, I noticed it wouldn't turn on. But I later found out it was turning on but the display is just extremely dark (visible in really dark room and still rings, flashlight, audio, etc.). I have tried restarting it (home button + power button) and I also put it into recovery mode and restored it on iTunes, but neither of these did anything. The screen is still very dark and I have no control over the brightness plus I have no warranty. Is this a hardware problem or perhaps a software problem since it was literally working perfectly a couple minutes before it went dark?
