I downloaded google photos on my note 3. So far, it's worked great. I tried downloading it on my girlfriends s4 and it tries to back up photos she doesn't even have. She only has 8gb of storage with no SD card. She has maybe a hundred or more photos. When I attempt to begin backing up her photos, it says backing up 1 of 5000 photos and the number keeps climbing, up to 9000 photos. Where is it getting these photos and how can I fix it?
