Other factors i can think of is probably not connected to wifi..or gps caused it be hot, that leads to some screen thingy going haywire. But doesn't explain the fact that it's fine when i unmounted it..

or its a safety feature where gps will render the screen irresponsive to touch so you wont disturb the map? 

Mine's working fine, occasionally the stupid Google Now pops up when I'm playing Magic 2014. Not sure what triggers it.

But so far, no multi-touch issues (not planning to put SP so no idea if that's what causes it), no GPS issues (only used with Google Maps, too big to use as a vehicle GPS). LTE model from Senq with Maxis Share&Surf sim. A tad hot on the upper part of the tablet when used long but I suppose it's quite standard for any device like this (MS Surface Pro could fry an egg at the back after using 2 hours).

Excellent bang for my buck. First tablet so can't really compare. Not sure why that apple-mini-with-retina-display-fella is trolling around here but it seems he's desperate for attention and trying to nitpick every damn thing. Rather spend my time using the tablet and looking for a decent case... this one looks great:

Ignore the sourpuss... this tablet is awesome. Add in the long warranty, no complains really.
