Touchscreen and charger issues

[Shirokami]

Just got my tablet however there are some issues.
First the biggest problem is my touchscreen sometimes goes crazy like in this video (not my tablet but same issue)

On my tablet the issue is mainly on the bottom of the screen.
I believe I have temporarily solved it by disabling touch and only using the pen. Obviously this it not optimal.
My googling skills have led me to believe it could possibly be a grounding issue in the tablet. Anyone had the same issue and tried to fix it or have any idea what else it could be?

Second issue you can see in the attached pictures. The charger adapter wont even fit on straight and I’d like to know if this would be considered safe to use.

Hi, sounds like a hardware fault to me.

I don’t think it’s a hardware issues. I think that is a grounding issues. That happens to me occasionally but only when I charge the tablet and use it while I am touching the charger’s cable. When it charge, I does feel some small static electricity on the back cover. Since the touchscreen has electromagnetic as well (wacom panel works by an electromagnetic field) so I think it gives an influence. I have seen some similar problem on I7 stylus as well on YouTube.
