Help Phone temperature

[psydex]

How can i check the internal temperature of the phone and what value is considered as normal , cuz my SGSII is getting pretty hot since i updated it to 4.1.2 (absolutely no apps installed - all default)

It is a great battery tool and widget, add widget on the screen and by default it shows you the battery left and underneath the phone temperature

Are there any "default/built in" ways or the only way is by installing external app?

As far as apps are concerned, I find GSAM Battery monitor the best there is

Thank you!

PS: Does this shows battery temp or GPU temp?

I assume there's no way seeing other temps without external app?
