Hey, glad this post made it back to page 1.
So since our initial dialog up towards the top, I had my phone replaced for a different issue (no, not scuffing or yellow screen) and I must say that the bluetooth in this new one is LEAGUES better.
(the following based on streaming pandora to my soundbar via bluetooth)
On the first one I had, it would start to fail when I walked from my living room (soundbar mounted on the wall) to my kitchen about 40-50ft away.
With this one, I just had it paired last night and I was able to not only walk to the end of my kitchen (add another 15-20ft) but I went out into the garage and shut the door and could still hear it without it dropping/chopping.
Before, it seemed like it mattered if it was in my hand, on the counter, or in my pocket (on the counter being the best of the 3). With this new unit, I can put it in my pocket and walk all over the house...
The odd thing is, I would figure if it were hardware-related BOTH would be impacted similarly. I looked both up and one was a week 37 mfg date and the new one week 38.
If you continue to experience shoddy bluetooth, I would request a replacement device ASAP.
