Question or Issue
When dropbox automatically uploads newly captured photos by my phone and uploads them to the 'Camera Uploads' folder, I am noticing that some* (NOT ALL) photos are being uploaded with a lesser quality. Resolution of the photo is the same, but the file size is significantly smaller, sometimes 60% less, and the picture quality is visibly very hazy.

Is there some setting which I am not finding to fix this?

*Some photos meaning that for example if I am out taking a set of say 10 photos, #1,#2 would upload with original quality/file size, while #3,#4,#5 will upload with lesser quality/file size, #6 with original, #7,#8#9 with lesser, and #10 with original quality. It's super random.
