My iPhone screen also have went black, but not permanently, it works normally after i restart it.

But still, the screen continue to become black and turn off then turn on,  repeat for several times a day.

At last, as i use a 16GB iPhone, so i thought that may the problem is caused by not enough storage. So i tried '''iMyfone Umate iPhone Cleaner ''to clear up my iPhone. I clear up all the junk files and temporary files, as well as many unnecessary files. Finally, my iPhone works well , and no black screen any more.
