Marble moves 

Actual Results
Marble doesn't move

This is interesting: 
http://people.mozilla.org/~nhirata/html_tp/accel_bug615597.html doesn't seem to work on the device.
http://people.mozilla.org/~nhirata/html_tp/ball.html does seem to work on the device (with some weird orientation issue... I think the up/down is reversed I have to take a closer look).

Could you relay the information to the developers of the apps?

I don't think this is an app bug - it's more likely a vendor problem with the orientation sensor. There's a similar bug on file for this for cut the rope as well.

Can we test this on 1.3 on a production device as a point of comparison?

Tested on 1.3 Buri, and the issue where controls are reversed reproduces; As in, the marble moves against gravity.

My money is on that this is a vendor problem. 

Sam - Do you have any ideas why this is happening?
