Upload status complete without sending any photos

[Hellmark]

I havr a Nex5T and I have a frequent issuewhere if I go to upload photos, it sits for like 10 or so seconds, before going "Status Complete" yet not a single photo was uploaded. It still will show X photos ready to upload. If I open another app, and try again it will sometimes work, but other times I will need to eject the battery before I can get it to submit.
