Droid 4 internal storage

[The_Red_Baron]

I have been looking around for a week or 2, didn't find anything about it. My question is: Why were there 2 storage partitions in the Droid 4?

I got 8 gb listed as phone memory and 8 gb listed as internal storage. The phone memory got just over 2 gb left and about 7 gb of the internal is free. The 32GB SD showed up as external storage is all free. I can't move anything from Phone to SD, I can only move some apps and data to internal storage.

My real question is... is there a way to make the internal 16gb back into one piece and move some app and data out to SD?

Thanks. I am just kind of at a lost at why Motorola would do that.
