Phone unable to connect to nebula and no sound on external monitor/mirror cast

Well, the cost of getting repaired and to send it to chine is too height. I could get an nreal Air.
Also I will try with an android 12 phone and check whether this will work. If not I will send it for repair.
Also what could be the reason that only screen mirroring is working?
Could it be something to do with the cable or software issue?

Does nebula works with Android tablets? Or it’s working only with Android Phones and M1 macs?

It is more like a hardware issue. Maybe you can also check if you have another USB3.0 cable. And about the Nebula, it should also work on some Android tablets theoretically, but as you know, we don’t test the tablets, cannot make sure of the performance.

This is an nreal light glasses, not nreal Air so it’s not possible to use another usb 3.0 cable.
