OnTouch locations tablets vs. phone

Question

I made a particle system that was designed for a tablet.. particles follow finger movement etc. anyways.. I implemented the gyroscope so when you tilt the tablet whatever direction.. all the particles fall to that direction. In the manifest I locked it down to landscape view.

So then I loaded it up on a Samsung Intercept. When I moved that screen around nothing was going in the correct direction at all.. So what I did to fix the situation is

if (width<800)  // My tablet width is obviously 800 phone is much less 
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
else
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

this fixes my problem.. but I'm unsure if this is for all phones? My samsung intercept is only for development and it's a POS IMO. Is it the phone or is this just how it works..

Some devices have a natural orientation of portrait and some have a natural orientation of landscape. This will affect the default sensor coordinate system for the device.
