The Lightray can record video in 720p, but the quality isn't anything to write home about. You'll still notice the occasional jelly effect when you move the phone around while recording, though in my tests the phone's microphone seemed well suited for picking up voices. It'll do for a Facebook or YouTube video, but you probably wont want to use it to film your feature-length opus.
The Samsung Galaxy S Lightray 4G is essentially the Droid Charge with just one or two new features and a much higher price tag. The phone's ability to play live TV is nice, but I'm having a hard time recommending the Lightray when you can get the unlocked Samsung Galaxy Nexus for considerably less. If you're set on buying a smartphone on MetroPCS, look into the LG Connect 4G: Although it does come with a bit of bloatware, at least it has LTE and more-modern specs.
