FileSystemStorage.delete() don't delete captured files in android

The following code tries to
i) capture a photo
ii )materialize it using ImageIO
iii) then delete it using FileSystemStorage.delete()

- All seem to go well above API. It works perfectly in emulator.

How ever,

- when run in Samsung Galaxy SIII (android 4.1.1) the gallery app shows "black 
ghosts" for images captured. Those images cannot be opened, file manager 
doesn't show any related image files

- when run in Sony Xperia (android 4.0.4) the images are still visible in album 
app, both before and after booting the device (to check possible caching 
scenario)

All the best,
