My phone screen goes black and becomes normal after sometime. During this I can receive phone calls and touch is working. Once it went black when i’m typing a message and after that I tried to type on keyboard and it is making keyboard clicks(I can hear sound)

Has your screen been replaced recently? There are a number of things that could be wrong. Here are a few off the top of my head.

  1. You have a faulty back light that could be fixed with a replacement of your screen.
  2. You have a faulty light sensor that is acting as if you are in phone mode, which cause the screen to black out.
  3. There is a software issue that may be fixed with a restore.

If its black all the time them your backlight fuse on the logicboard has gone and it needs replacing and its common on ipads when the screens have been changed and not useing anti static gloves,good luck
