Galaxy s6 86°C is that normal ?

Hi I just got a new Galaxy S6 and it's overheating when playing game or taking pictures .. And it's very very hot .. More hot than what I read about S6 heating ..

So I did one test I installed a app that monitor temp and when I did a benchmark it went to 86°Celsius !

I did a screenshots when it was 82 .. Here's the screenshot..

So is my device faulty or a normal behavior ?
