Thank you for the reply!
Well, it seems to just get too hot from what it seems to be considerable acceptable. I thought it heated up to much and so did some people that used my phone.
I was out today when i noticed it just by browsing the web (not on wifi, just on data and without any app errors), so i didn't get any temperature info but i do have a ir thermometer at home that i will use to get some info on the actual temperature. The rise on the temperature (again, don't know exact values but i will get back on those) was a bit uncomfortable, especially when using the screen that got a bit to hot as well.
Maybe i was expecting the phone to heat less than it does, so maybe its just the way the hardware works since it seems to be reports of excessive heat from phones like the z2 and the m8. Still, i will try get the temperatures when the phone starts to heat up to the same point i have experienced this past days and reply back here to see if its normal.
