Fixes

  1. If you are having black screen while you have visited other's base or your own base (just keeping on tapping left side where screen is black) and eventually you'll tap the boat and the screen would be fixed.

  2. IF you are in war and have not attacked yet then just press the back button of the phone and the screen is fixed.

I hope this helps.
