Question How to fix iPhone black screen

[Shirley229]

My iPhone got an black screen. But there's no bump or fall on this iPhone these days. So I guess it might be a system issue. I find a lot of system repair software like TunesKit and MagFone on webs, and I just wanna know whether these apps will cause data loss on my iPhone.
