I hope someone can direct me to resolve this issue. I have MacBook Pro and iPhone 6s Plus. My Other data is 13GB and I was able to find out this is to do with syncing my videos(not movies) via iTunes. I did clean restores multiple times and apps, music, and photos are just fine but every time I sync videos back into iPhone this other data comes back. For the first 5 seconds after video sync is done, iTunes display that I have 13GB in "photos" in pink, which I think is the correct info. Then this 13GB automatically moves over to yellow "other" leaving pink "photo" with like 600 mb this is probably the pictures. Does any one having same or similar issue and were you able to fix it?
