To make the armor plate warm?

First my problem. I have a huawei psmart and my panzer disc on the edge does not clean on the edge and rann press ghet not synonymous.

Now my question? Is it good to warm the glass? And funkzonirt over the hoods?

No does not work.

It's not because you did not put it in the middle.

Buy 3 D glass then you do not have the problem.
