How to find old apple iPad wallpapers?

Last year (2017), I got an iPad Air for Christmas, and I had a background with a red planet on it, and a background that was gray with dots on it. My sister changed the backgrounds and now I can't find the old ones (I guess there was an iOS update that got rid of them). I really want to have them back because I'm a sentimental person and when little things like this happen, I get really upset. I found a screenshot I had taken (probably without realizing it) of the red planet background, but it has the time on it so I currently can't use it. If someone can tell me how to attach a picture to this thing, I could show it to you. The red planet is red and white and orange striped and has a small moon in the corner of it, and you can see the majority of the planet on the screen, although the front part is in a shadow. Can someone help me find the background with the planet and the one with the little gray dots on it? Thanks!

Apps opening by themselves? IOS?

I have an iPad air 2 and only sometimes when i exit out of an app and enter the home screen. I start to see some apps have a grey look on them as if I was tapping on them to open it. The only thing is that it doesn't open the app on my screen I only see it click on the app. Something opens the app then leaves after about 5 seconds. It then clicked on my Imessage which is where I shut off my iPad completely. Is this a glitch or someone who hacked my iPad?
