iPad "dead" spot.

[Ellyidol]

I seem to have noticed my iPad having a "dead" area.

Take for example, when you drag apps around your home screen, whenever I pass through that certain area, it automatically drops or returns back to where I picked it up, as if I let my finger go.

Also in some apps, like dragging apps, when I come over that area the same thing happens. Its as if I let my finger go.

There's nothing visibly wrong like a crack or whatnot, what should I do?

In PL terms, the dead spot covers a bit of the lower left skills in the skill map. About 2 of them. I get to use them still, but for it to detect my touch takes awhile, especially dragging.

Should I bring to Apple? Do you guys know anything about this?

EDIT:

Its somewhat like this (this isnt me, just found video).

Except that mine goes from that dead spot vertically up and down.
