Thanks for the reply. I was talking to one of our users just now and he was having this problem trying to upload just 1 image without touching the downscale option (I don't think any of our users ever used that and always kept everything at "Actual Size") and it was failing repeatedly for him. Only after repeating the upload nine times did it finally go through, so I don't think the downscale option or the image count (at least for a single session of multiple-selected files) mattered. He also told me that restarting his phone after encountering the problem always seemed to help to get his uploads working, but then it would eventually start failing again, so I can't tell if it's something that builds up over time.

That might explain why I have not been able to reproduce the problem with a phone that has never been used to upload images here since these users upload a lot of images to our web app in a single day.
