Heating almost everytime

[AkiSSJ]

I have the C6903 version, got the Z1 last week (updated it to the last version that was available after I got the phone),I don't use a Micro SD, used to test it but removed it.I will specify all of the details.

The problem is when I'm using Facebook,Messengers or Chrome browsing on either WI-FI or 4G the phone gets warm on it's back (only WI-FI or 4G, the others like Bluetooth,NFC,Location or synchronize are off, only STAMINA mode I use, the only background running apps are WhatsApp,Facebook Messenger and the OS with it's related processes)

It get's warm here first http://postimg.org/image/y41l6c0kd/ then after a short time all of the back is warm.

This happens when I play games too(depends what game), a 3D game makes it very warm like Asphalt 8, the games like Candy Crush Saga does very little warm.

This happens too when I watch videos on Youtube.

Uninstalled Facebook,Facebook messenger and the warm is a bit little now when playing games, it gets really warm here first http://postimg.org/image/y41l6c0kd/.

This happens too but very much and faster after I make photos and mostly only one with blitz turned on.

Any ways to try to fix it? Very annoying this warm and I don't think I want to let the phone at service for weeks..

I know there are more topics related to this, i made a new one because it's very recent and I really don't know what to do, made a lof of things,unistalled etc and same..

Sorry for my english.

It is normal for a phone to get warm when playing games and also using 4G, watch youtube and Videos - However if you feel it's getting to hot it should warn you and either switch off or stop the app or apps from working but you could have your device inspected to make sure there isn't a hardware issue causing this - Contact Xperia care if you feel this would help http://www.sonymobile.com/global-en/support/contact-us/

Forgot to say that the phone never shuts down due to heat or an heat advertise, is not very bad the warm, just normal.
