Just upgraded to the OGP from Note 1 and love it. The only issue I currently have with this phone is it is kind of warm after few minutes of usage. It does not get hot, just stay warm after 5 minutes of usage and getting warmer but not uncomfortable too warm yet. Does everyone have the same issue ? I suspect that I may have a bad battery since my battery only lasts around 7-8 hours with around 3 hours of screen time only. Should I go exchange for another one at AT % T store ? I have a week to decide. Thanks all.
