4k laser projector remote stops working

When we run the projector, the remote turns it on just fine. But after the projector is on we lose all ability to control the projector with the remote and have to resort to using the phone app. Its very annoying. We have changed the batteries in the remote and it had no change.

I am having the same problem. Is there a fix?

There is a fix.

This is what I got from support and it worked:

I’m sorry to hear that your remote is not working properly with the VAVA 4k UST Projector. Let’s see if I can help fix this.

It sounds like you are able to only use the remote for turning on and off the projector, for this situation it may be that the remote is not properly connected to the projector.
Please stand within 2 feet of the projector and press and hold the return and menu button for approximately 10 seconds, this is a sure-fire method of getting the remote and projector paired together.
This pairing process can be done from the home screen of the projector for simplicity.
