A2 lite more like A 2 nothing.

I brought an A2 Lite 2 days ago to replace a cheap keyboard for my x8h. Well the 1st day it worked great 2nd day ready just to throw it in the bin.

Have to press the OK button very hard or multiple times.

The return button dose as it pleases. Not just in xbmc but on the native android pages.

Brought the lite version as its supposed to be more compatible with the x8h but now thinking I got it wrong.

Please advise on what to do?
