My solution was to get Emteria OS or Konsta's Android images which will work on PI3. I recommend emteria but it's a commercial product, you need to register and use their own disk imager. I mainly use whatsapp and nintendo switch payload injector on it. Other stuff like uploading instagram photos ca...
I was a bit hesitant to start off rolling when last disk image was few months old. In the end genup went really well from minimal install to stumpwm desktop.
Edit: Dang it! How do i drive this thing
