Got my G2 back today..... same exact phone... they said they "updated software"... indeed likely just a .tot restore (which I had already tried before sending the phone to LG btw)..... guess what?
Same thermal throttling/shutdown issue while streaming via miracast. I called LG and now I have to send the phone back again.... I dont get it.
