This is totally an unconfirmed rumor at this point. A friend of mine who works at Radio Shack called me last night and said her manager was told to pull the Bionic from the shelves due to some risk of the phone catching fire while charging. I just wanted to see if anyone else has heard of this. So far I've had nothing more than minor bugs with my Bionic, battery life is great etc. I've never noticed my phone being any hotter than my og droid was, and this only when really pushing it with hotspot mode on.
As I said this is unconfirmed and could be about a different phone model or a misunderstanding. But I will say that I didn't leave it plugged last night when I went to sleep lol.
