After trying out various combinations for the glBlendFunc, I've noticed that most of them have no effect on my phone (HTC Desire) while they work just fine in the emulator. On the phone, only 0+1, 1+0, 1+1 have any visible effect, while all other combinations seem to be ignored. Is this a hardware limitation? P.S. I'm running my tests o...

Hi at all. Today, I placed our new app onto the market store. It can be found by most mobile phones - unfortunately, it cannot be detected by one specific model which is used by one of our customers.
