I am testing it on a Android 2.3 tablet....and it has a multi touch screen.
Using Qt 5.2.1 for Android, working on Ubuntu 14.04.

Someone said on a post of mine that Qt gestures are a bit buggy, but surely there should be a fix/alternative way of achieving this, seeing how gestures are the main ways of navigating on a tablet/smartphone, can someone help me/point me in the right direction?
