I looked at the CPU temperature (in "System Tuner Pro v2.5.9") after 15min playing "NFS: MW" - it was 62C. Upper half of the screen became very hot
And also after a four-minute HD-video recording the temperature rises to 51C.
In standby mode (display is turned off) the CPU temperature is about 40C.
It is normal or it would be better if I return my phone?
Confuse that after playing it is uncomfortable (for the ear) to make a call...
It is normal! No matter what ppl will say, you have a bad ass passive cooled QUAD processor in your phone and this behavior is to be expected from it. I have many phones in my life and indeed Samsungs tend to get hotter than other ones.
But to make your life easier... I also play the games you do and indeed it gets "very hot" and by that I mean imagine making a hot cup of tea and let it cool for 7-8 minutes...which is still hot. I left my phone playing by itself NFS from full charge till it batter emtpy. Never ever had an issue with it.
The basic principle remains. If the proc gets overheated (unless you are living on hawaii/mexico, playing NFS on the naked sun) overcooking the phone, it should still shut down by itself.
About the recoding part that might be correct as well. I am not sure which algorythm note 2 uses, but capturing the video and encoding it into .mp4 requires some serious processing power. (just try to encode some .mp4 on your desktop pc and see your i7 crank up to 100% and fans try to fly out your pc
