I received my "like new replacement" Droid RAZR maxx HD from Verizon the other day. To my surprise, it has the bootloader unlocked. It actually came from Verizon that way. I was super excited with this because its running the latest update but allowed me to root with no issues. Small issue.. Numerous times I've noticed while music play back or even doing nothing...if I place the phone , speaker side down, or close to an object I get a horrible high pitched feedback/squeal. Any ideas? I really hate to call for another replacement due to the fact of the non existent ability to root or is there..? Please help.
