Usually I can upload the fisrt photo I take, but with the second photo sometimes I get "Error uploading file" and other times I get "Your image has been stored in your private area" but in the private files on the moodle site I just can see the first photo.
The same happening with iPhone 4S and Samsumg Galaxy Core with moodle mobile 1.4.3. I attach the "Device Info".
I do not attach the log because it is always empty. (Settings -> Development -> Show Log)
