My tablet detects touch by itself

Hello all.

My tablet (HUAWEI MediaPad T3 7) is detecting touch without me doing anything (at random intervals). It’s gotten to the point where I’m afraid to start commenting on an instagram picture because it’ll press enter by itself before I’m ready.

After looking online here a bit, I found that some people have had issues with third party screen protectors.

As I don’t think huawei offers screen covers for their tablets (I’m using a matte screen protector because tablet screens are way too glossy) do you have any ideas on how to fix this? Hopefully without having to ditch the anti-glare screen protector.

I think it was caused by the case after all. I removed it and it is fine.
