@JKH62, that's not normal. I've had android from the very beginning and I've never had to do anything special to keep one from locking up while charging. It's under warranty, send it back.
I am past my grace period and if this "fixes" the lock up its not a biggie. I am holding off rooting it for a while in the hopes of a firmware update. Casio is slow to update devices but they pushed one for the old command so they do support their hardware even if its at a snails pace.
I have a LOT of crap disabled thru the Verizon settings page and they flash a disclaimer that it may cause other apps to misbehave. I think the phone is an improvement over the old commando but the new camera was a step backwards ( it sucks).
