Long story short: Bluetooth sound (on my end, the listening end, not the other end) sounded terrible. Took it back to AT&T today. They tried: 1. My phone 2. Another new phone 3. The phone on display 4. Tried all the phones with my Plantronics Voyager Pro HD 5. Tried all the phones with my Plantronics Savor M1100 6. Tried all the phones with a new Motorola BT headset from the store 7. Tried all the phones with a different new BT headset from the store 8. Tried all the phones with a Jawbone BT boombox speaker from the store The sales person and the store manager both confirmed the terrible sound on the BT receiver of *all three devices*. This could be a major design or manufacturing flaw on the HOX+, unless this particular store just got a bad batch of them. Sadly, I had no choice but to turn it back in. I swapped it out for the Galaxy Note II. It cost me $100 more, and the screen isn't quite as bright/white, but it's very smooth and pretty damn cool. I've had very good luck with Samsung in the past. I have really big hands too, so after a few days, I'm sure it will feel normal. It's really too bad. I LOVED the look and feel of the HOX+. Oh well.
