This happened off charger, just playing a high quality graphics game for 20 minutes.
Just seems a bit high to me, but any further insight is welcome. (as a comparison i've read on the Galaxy Nexus forums that a few folks are getting ancy at around the 120°F mark as well).
Maybe the Rezound is just has a poor design in reference to heat dissipation? Maybe I have a defect? I can live with it, so long as I know its not that big of a deal. I'd like to avoid waking up next to a phone shaped melt hole on my night stand.
