iPhone 6s screen goes off then gets back normal in 10-15 minutes.
Hello everyone. I bought my iPhone 6s 64GB Space Grey on late December 2015. It came with Samsung A9 Processor. For the last 3 months it started to shut its screen down randomly at least 1 time in 2 days. I Think it has something to do with the LCD backlight because touch screen works on completely black screen. I can still receive calls by memorizing where to touch. Then on an average of 10 minutes, it gets back to normal. Is there anyone else having this issue? Or any suggestions? Thanks in advance.
(By the way closing and opening it or rebooting with power and home button at the same time does not work. Whatever you do, screen gets normal whenever it wants. I tried hard resetting, formatting and back-up but the problem is still there.)
note: Probably a coincidence but it never happened before iOS 9.3
