Samsung Galaxy S6 Internal Memory reading 16 GB instead of 64 GB ?

[AC Question]

After I have updated my Samasung S6 to Android 6.1 through Odin3, my internal memory reading just 16 GB but it should read 64GB.

There will be over 10Gig just for system data...
Wipe cache partition should give you a bit more free memory...
