[Q] Post-ICS Bluetooth Distortion
Does anyone know if there is a corresponding radio upgrade along with the 4.2.2 update?
I've been struggling with the warbling bluetooth noise during hands-free calls since the ICS update. This is not
the same as the bluetooth streaming problem with 4.2.1.
I was hoping and praying that the 4.2.2 release would fix the crappy bluetooth reception along with the streaming problem, but Google never did officially acknowledge this problem.
Here are some "traits" of the problem:
- Happens during bluetooth phone calls
- "Quiet" time of the call is worst
- Noise shifts frequencies and typically sounds like RF interference
- Noise "warbles" the other party's voice, making it hard to understand what they're saying
- Gets worse as you turn the volume up (which I usually do when driving, as my car is loud)
- Doesn't affect music over BT much for me, though many other complain about the "highs" (eg: cymbals) being distorted
- Is worst with the 4.1.1 radio; using the 4.0.4 "FA02" radio helps the problem some, but that radio has other connection-related issues
- The problem started after the ICS OTA update
- Reverting back to 4.1.2 fixes the issue for most people (downgrading is not officially supported by Google. You need to use the Galaxy Nexus Toolkit)
At any rate, I found this earlier, but am not sure it can be used on Verizon/LTE. I just don't know enough about radios and such. If it's not a flashable .zip, I have no idea how to install it either.
Here is the best collection of info I can find on the problem.

I would love to find a resolution to this problem. It amazes me that something so fundamental (hands-free calling over BT) could be so jacked up, but not get the attention it deserves.
