Weird Screen on Luymia 1520

[Cugami]

Hello all,
I have been using the wp10 mobile from the first insider program. Now with the latest build, it is ok to use my 1520 as my daily business driver and very happy with it.
But these days I am experiencing very interesting stuff on my screen. It started when I open a web page on edge. the page suddenly started to navigate down and zoom-in, out by itself and the screen and the buttons freeze. I need to lock the screen and unlock again to bypass it.
Anyone experiencing similar things?

That may be a hardware issue. I experience a similar thing on my 1520 (I just can't press any of the keys, so I have to lock and unlock).
