iPad Pro Generation 1

I have an iPad Pro generation 1 and there are a few problems. I kinda broke it and it’s not been working properly. For example, my front camera takes pictures like this;

Theres also a big hole on the side of my iPad. It happened to my sister and her iPad started glitching but fortunately, mine hasn’t. The screen of my iPad sometimes glitches and gets into random apps or presses random things and sometimes it doesn’t even work when I touch it. I don’t think that there’s any way to fix the problem but does anyone know any ways to fix the smaller problems?
