Z3 Overheating fast while recording 4K

[alirezanasibi]

Yesterday I noticed when I tried 4K video recording for 1st time, top back of Z3 ( around camera ) got hot so fast and I received a message that device tempreture is going high. It's weird as it happened in less than a minute of recording. Is this normal for Z3?

That is indeed normal

It is something Sony have acknowledged. I think it's partly down to the water tight build, the heat from the processing can't escape the phone as quickly as it needs to.

Maybe put the phone somewhere cool first if you plan on using 4K!
