1 week ago I bought a new Samsung galaxy nexus. It runs smoothly with no hardware or software problem. I access it comfortably. From last 2 days whenever I keep it for charging the phone gets heat up. I thought it might be due to the charging but even when I unplug the charger and use the phone for continuous 10 to 15 minutes, it again heats up. And I donít feel that it is a normal behavior. Can anyone tell me what could be the problem?
