How do I get tilting screen to work on my Galaxy tab

Hi all,

Can anyone help? I have just bought a Samsung Galaxy 4 tab as my HP Died.

I have been making a "Doodle Jump" game using the infinite jumping template.

Well on the HP everything was fine. But now when I preview it on my Galaxy it won't tilt from left to right.

I have placed a left and right touch button to move the player and this is working fine.

But it won't tilt!!!

I installed the real Doodle Jump to see if tilting screen worked and it does.

In advance

Thanks

to use tilt you need touch and gama orientation I think.

Yes I know I have changed nothing other than my tablet.

It's on charge at moment will try some more later.
