Android's native Linux Terminal app is live in Google's latest update
Debian on demand?

For months now, we've known that Google intends to release a native Linux Terminal app that would let users run Debain in a virtual machine on their Android smartphone. Why would you want to run Linux on your Android smartphone though? Well, you truly wouldn't — though support could be a huge boon for developers, security professionals, or those that need access to Linux-exclusive applications. It runs in a safe virtualized environment, so it doesn't really mess with your normal Android phone functionality.
