Save image to Photo Album weird problem

Hi guys,
in my app i take a screenshot and later use the screenshot (called screenshot.png) as a texture on a simple play just as a preview of what the user is going to share.

If i share on Facebook or twitter its all fine but if i save it on the photo Album even i change name (for example adding the time.now) the first scrennshot its fine but if i take a new one i have two copy of the last screenshot. Basically its replacing every screenshot previously taken with the last one i did.

I’m using etcetera to save the image on the photo Album.

Anyone had the same problem? Really struggling with it.

Thanks!

anyone with a comment on this…still trying but no luck…
