I know about your post and I did verify it and the error is about 200 mb, itunes says I have 200mb more free but that's about it. I really don't care about 200mb error since my other was 1.6
Are you saying iTunes is reporting the same amount free as your phone or are they different?
The reason I mention this is that it wasn't just the free space that is reporting wrong on my device. All the different "storage" values are wrong. For example "Other" is showing 1.77 GB in iTunes, but when I hard reset and reconnect it jumps up to 1.99 GB (along with other data storage values changing) before going back down to 1.77 GB.
For what it's worth, if I use the iMazing app, which appears to be reporting sizing correctly for Photos and Apps, my "Other" data reports as 4.1 GB, so I don't know if iTunes is reporting sizing correctly.
