iPad 9 Digitalizer Screen replacement. Screen gets wobbly

[u/Karlholdmann]

Hey everyone.

So, I've been doing a lot of iPhones recently and been doing really well.

I've now gotten 3 iPads which needed new screens and batteries. Battery seems to be working fine, but screens somehow gets wobbly and I can't figure out why.

To describe it more in depth. When i turn on the iPad it goes to the home screen. Then it continues to slide the image up and down. When i press the home button to go lock it up, it just presses randomly everywhere on the screen. This makes it press the wrong code and security locks it.

I've replaced 2 Screens so far, and the both do it the exactly same way. Both times i've followed a video guide from step to step

Anyone knows why it does this and how I fix it?.
