Happened to me too. Any ideas? The problem seems to be on the Android device though, I connected through my wifes phone and it worked. Also, if I just grab the photos through USB or from the SD, they are fine.
Also it sometimes slows down my phone to a ridiculous extend (Nexus 5, latest stock +root), so theres definitely something wrong with the app.
But since the 1.12 firmware, I did get some freezes on the camera too, I never got any freeze on previous firmwares.
