Did you copy the payload which worked with the pc to your android device and tried that?
If you close rekado on your android device and then connect your switch to it, does then rekado popup and shows the payloads to send?
If you have the correct OTG USB cable it should found the switch and should show the payloads to send.
If it doesn't, I think, it's maybe not an OTG adapter.
What cable are you using to connect the switch and your android?
I'm using a male USB C to male USB A cable together with an OTG USB A female to male micro USB B for my android mobile phone.
Just searched for the "SUBMITURB" error on gbatemp and found this:

It seems it could be an android problem too. Maybe you can try another mobile phone?
I looked through the issues list for rekado on github:
https://github.com/MenosGrante/Rekado/issues/3
The developer says the same: It could be an OTG adapter problem or it could be caused by using EHCI controller in the device and all payload launchers for Android need XHCI controllers to work properly.
