weird android graphics glitch

I just made my first android game but when I tried the game on my phone the graphics are all gitchy, the sprites leave a trace behind (kinda like when old windows 95/98 hanged) is really annoying and trippy; I cant take a picture because the camera I have is the one on the phone (lulz); the phone is a sony Xperia typo
the game is a 2D side scroller and Im using 2D toolkit.

EDIT just found this old windows image, it looks kinda like this:

In the Android build settings, try enabling 24bit depth buffer.
