sprite generate an echo in the screen

[zeusrami]

Hi, when an tk2dSpriteAnimation is running.You see  in the screen the current frame and the previous one (blurry andmore transparent) like an echo.
The same things happend if I translate a tk2dSprite to quickly.
Do you know what could be the problem and how to correct it can I correct this issue.
This happend in an sony xperia phone.

Thanks Ramiro

This is either a hardware issue, or some issue with unity on the hardware. This isn't anything to do with 2D Toolkit, I'm afraid.
