Touch screen problem xz2 premium

[TracyScreamwork]

The touch function isn't working all of the time and doesn't register much at all when using games or apps and I've only had the phone for a few weeks and I have to shut everything off to get it to start working again would this be a firmware problem or is this phone a lemon?

Could you test your device?


Settings > About phone > Diagnostics > Test

Oreo

Settings > Support > Tests

Also, does your phone has a protective case, film or glass?

I've been testing randomly and sometimes oi can get through them and other times I can't, I don't have any film on the glass and have to restart at least every second day when it gets really annoying. I do notice it more when I'm playing a game where it will become a little jumpy before not registering my touch.
