Comment (by n8fr8):

 The root / transparent proxy feature is a bit of a hack, and can work
 differently depending upon your device, kernel and firmware/OS version. If
 you want to see the recommended setup for this use, please read
 mikeperry's blog post here: https://blog.torproject.org/blog/mission-
 impossible-hardening-android-security-and-privacy

 There is also an app called Orwall which attempts to automate some of the
 setup from Mike's post for transproxying.

 Otherwise, using apps like Orfox which are tuned for Tor, or ChatSecure,
 DuckDuckGo, etc which can be configured to use it easily, is the best
 option, followed by the Orbot VPN feature.

 The main downside of the VPN is that we are relying on Google more for how
 the tunneling works, etc. We aren't directly controlling the iptables
 network rules. This means, while fine for proxying, getting around
 filters, reducing traffic surveillance overall, it is not fully in our
 control. We interact with it via an Android API, and not lower level
 rules. Still for people without root, it is the best option for a "send my
 whole device through Tor". Also the VPN doesn't currently support
 accessing .onion sites and services, but again if you are want to do that,
 you should use a Tor-aware app.
