Default Bluetooth

Not sending or receiving to paired devices. I have a like new Droid 4, that has the latest official update. It will pair with devices but will not transfer files. Any advice will stop me from pooping my pants.

Sent from my SeXperia Ion
Current phone: Xperia Ion LT28at
Rom: MIUI v5 3.10.25 Locked bootloader (of course)

Previous phone: Xperia X10a
Rom: Oodie prime MIUI

Xperia Z is on my wish list but Im really digging the Ion.
