I think you should try the following. I had a customer with the exact same issue and I placed a screenprotector on it and it stopped. I don't know if this is for everyone, but I think it's worth the try. Just buy a cheap screenprotector and check if it solves the issue. So again I can't confirm it works all the time, but if you're out of options, give it a try.
