Hi @GarboCries, Brave Rewards most certainly works on Android 
Have you read through any of this??
Also, if you go into the Brave browser app settings on your mobile:
…you should go through and set up everything as you prefer.
In your mobile’s settings…
…find the Brave app and…
…go through and check your settings, especially those indicated.
There’s a great FAQ, too, to check out once you have all the above set up how you would like.
I hope this helps you
EDIT I should add that in that last pic…
…it remains set at “No” for me, despite Brave being my default browser and me allowing quite a lot. I think it’s because I don’t allow Location. <shrug>
