FPV lag on visuo xs812

I found some information here which may be helpful to read through. They mentioned the issue of video lag and seemed to find a few potential solutions which were: to use a wifi extender, use a different app (mentioned in the link) to connect to the drone, or adjust settings of your phone like screen resolution and processor power if possible.

As I don't own this drone, I'm not sure that these solutions will fix the issue. But if the video lag persists, just know that you really can't expect very low-latency video from a drone this price.
