Particle system documentation for Gear.

Hi to everyone, I have to make a project for samsung gear, exploited S8.
On unreal engine there is little documentation about it while there is a lot more documentation for mobile in general. Can I still rely on the guidelines for mobile documentation, though I work specifically with the gear, which has separate documentation?

I can not find anywhere on the particle system documentation. I need to implement an application running on oculus rift and Gear, so I would like to understand the limitations of the “Gear”
