Im having the same issues. I mostly hear it during netflix videos. I hope it can be fixed with a software update. I finally got my phone set up the way I want it and I don't wanna have to get it swapped out.

 

Netflix is a different issue. That's a codec issue and could be fixed with software. You can minimize it by enabling audio effects and selecting balanced or bass but it is still there. The horrible feedback loop at low volume in the headphones is likely not fixable. That is some sort of ground loop issue in the chip is my guess. The rattling in the earpiece on calls is likely one of the cameras. Tap the top of the phone on the backside and you can hear the loose pieces that vibrate on a call. The incredible 2 has the same issue. What a piece of crap!

 

I'm just now having the same problem, but I've had my Bionic since it was released and this is the first of it. It's never been mishandled (dropped, went skydiving, took a bath, etc.) and it all of a sudden just started tonight.

Did you ever get this resolved with the Big V? I wonder if, after being on hold, being transferred to the wrong people, etc. (I have a business account, they're a little confused there sometimes) they will fix it.

I love my Bionic, and I'd hate to have an issue like this for the next 1.9 years.

 

Loose parts in one of the cameras. Try using camera and video modes a few times. Mine used to be worse. Either I've gotten used to it or the lens got reset.

 

Thought I would post something other than the crying & bitching threads.

I found an app that I think is pretty cool. It's called "Smarter Alarm". I wake up to my Bionic greeting me by my name then the cool stuff - time, weather (& forcast), stock report, news & sports (how I configured to hear), tells me scores of MY FAVORITE TEAMS (if they played the previous day), tells me my appointments for today, tells me "this day in history", "famous qoutes", and your own customers message (if you choose). It's TOTALLY CUSTOMIZABLE.

Note: I did previously update my Bionic to talk smooth (no longer robotoc "Navigation" voice)- free Ivona app

Getting back to Smarter Alarm, I love it...only bummer is it cost me $4 (free version is too limited). But I would buy it again
