Can you give us more detail on this...
It seems that it now works again. But before if you wanted to know, was that the transfering of the image seemed to fail, as the image located in the folder was 0kb
The mobile device took a picture, but the transfer loader was continuously rotating, which you can click on cancel, to cancel the transfer.
It worked on all other android devices. So maybe it was a local error?
Anyways this can be marked as resolved, thanks for your help.
