What do you considered as hot?|
Its rather normal it may be a bit hot, specially during heavy usage and/or if using data connectivity

If it gets to the point of overheating, the device will auto-shut down to prevent damage.

As for now, you as a user, all you can do to help you decreased it, is simply lock the SoC speed a bit lower.
There's several apps on the PLAY Store, xda , that can act as an interface for that
