One issue that's been bugging HTC ThunderBolt owners is the inconsistent audio recording when using the camcorder on the phone. Sometimes sound is record, other times its muffled beyond recognition.
The good news is that HTC has confirmed to us that it's tracked down the problem, and a fix is in the works. That means a software update, of course, and these things can take time to be approved and pushed out. But good on HTC for tracking it down so quickly.
In the meantime, there are some supposed workarounds, from covering up one of the microphones to using a third-party video recorder. Anything else we should try? Hit up the forums for more, and we've got some video samples after the break. [Android Central Forums] Thanks to everyone who sent this in!
