Never had a squeak or squeal with my bionic. But i do have to report random data reboots very much like a hard handoff. Data drops then picks up on 4g.
Update* ive been having sporatic volume issues since installing 238. Sometime ill go to play a video or listen to a song and itll be completely mute regardless of where the volume is set.
Ill have to either make a call or restart the phone to get the volume back.
This is a known hardware design flaw. Some phones have it / some don't. Software will not fix 100%. If you are still within your warranty period you may consider going the CLN route; lots of phone exchanges though. VZW is offering the Nexus as a replacement for those who don't want the hassle. It's a decent phone.
