The heat development is significantly better compared to the G4, although the speed has been noticeably increased. The LG SW is resource-saving and can be partially removed. It is absolutely not comparable with Samsung, for example. You always get updates very quickly because no huge adjustments have to be made.
The device cannot be dual-sim.

The heat development is normal, it gets quite warm when playing games, but this is no different with most other smartphones. Bloatware is not a hindrance, there is very little of it. I meant there were 2 versions of the LG5. This one is not a dual version, but the memory is expandable.
