Because you are using the emulator...
Actually I'm using a Samsung Galaxy SIIX Hercules (SGH-T989D) with Android 4.2.2 Running. I've tried disabling mip-maping, enabling tri-linear, anti aliasing. I've tried opengl 1 and 2 to no avail. I'm stumped. I've tried it on multiple phones so I know it's not just mine.
I wish I could describe it better, it's almost like a graphics card glitch but it's not linked to the graphics card. The texture kind of stays while the camera moves for a split second, goes pixelated and has lines through it.
