be aware if you want to do some illegal stuff from tor browser for android. 
Every installation is recognized with an unique fingerprint. Consider it just a "at least it hides my ip" solution.
My opinion is that this is a limitation of the bad (and young) firefox for android. 

 Wouldn't recommend doing anything like that from a Google device. 

Tails USB + VPN or Qubes OS + VPN. 

Don't use any VPN service that collects any personally identifying information either, regardless of their logging policy.
