Storage availability is displayed incorrectly on iOS devices

[Prabas]

I've noticed that my iPhone 6s Plus and 6 started displaying incorrect storage information. One iPhone is on 9.3 Beta 2 and another one is on 9.2.1. When I connect them to iTunes, the remaining free space is displayed correctly.

To make sure, I started downloading gigabytes of music to one of the iPhones and I keep getting notifications that my storage is full, though downloads are still happening and each time I refresh my storage information on iPhone's Settings.app it varies from 0 bytes to 300MB.

So, did any of you noticed something similar?

Storage left is never the same on iTunes as it is under Settings on iOS, but "Other" is not being considered on iTunes for some reason. I think that's what's taking up the additional 4.86 GB (wow).

Get some space by getting Battery Doctor, man.

Had exactly the same on my girlfriends 6s this month. It was showing that she'd used all of a 64gb phone, but could only account for 15gb in the storage section of settings (by adding all the apps together). Restored the phone, then restored backup and the problem returned within a few days. Restored again but with no backup and the problem seems to be gone.

Gotta figure it's a bug related to iCloud.
