iPhone 6 - 16 GB Storage almost full;
I have an iPhone 6 - iOS 10.2.1 - 16GB
The capacity in the *About* says that I have 11.92GB ; when I enter the Storage & iCloud Usage it always says that I have 0KB available , and it shows that I have used 11.71GB ...
The problem is that when I calculated the apps usage (5.37GB + 897.6MB + ... ) it seemed that my usage is actually 7.28GB only , which is logically the right capacity .
Is there any method I could free up some space ? or is this normal ?
