Ubuntu for Android is an upcoming free and open source variant of Ubuntu designed to run on Android phones. It is expected to come pre-loaded on several phones. Ubuntu for Android was shown at Mobile World Congress 2012.
- Both Ubuntu and Android run at the same time on the device, without emulation or virtualization, and without the need to reboot. This is possible because both Ubuntu and Android share the same kernel (Linux).
- When the device is connected to a desktop monitor, it features a standard Ubuntu Desktop interface (Unity).
- When the device is connected to a TV, the interface featured is the Ubuntu TV experience.
- Ability to run standard Ubuntu Desktop applications, like Firefox, Thunderbird, VLC, etc.
- Ability to run Android applications on the Ubuntu Desktop.
- Make and receive calls and SMSs directly from the Desktop.
According to Canonical a phone needs the following requirements:
- Dual-core 1 GHz CPU
- Video acceleration: shared kernel driver with associated X driver; OpenGL, ES/EGL
- Storage: 2 GB for OS disk image
- HDMI: video-out with secondary framebuffer device
- USB host mode
- 512 MB RAM
Note: Most of the phones do not allow to simultaneously use MHL and USB on one port. To do such you need separate HDMI port (Motorola Razr/Razr HD, Xperia S/arco S, Asus Padfone) or upcoming MHL2 port. There is also unstandard solution as in Samsung S3/4/Note2.
Katherine Noyes, writing for PC World, noted "As a longtime Ubuntu fan, I have to admit I'm especially excited by the prospect of having my Ubuntu desktop available on my phone, wherever I go."
Joey Sneddon, writing for OMG! Ubuntu! noted "Both [Android and Ubuntu] run at the same time on the same device. The net result of this is a super efficient workflow."
Ubuntu for phones

In a conference in London, on 2 January 2013, Mark Shuttleworth unveiled the concept for an upcoming mobile operating system - "Ubuntu Phone", that will probably be released "by the end of the year. The device(s) on which it will be released will deliver a personalised, full screen-to-screen experience - with a 'welcome screen, not a lock screen'". Thereafter, a concept for one phone with Ubuntu for Phones was published on Ubuntu's official channel on YouTube, in which it is shown as a simple, rounded bar-type smartphone, with no buttons on the front, unlike what is usually seen on most smartphones. The Welcome Screen is shown to have the standard Ubuntu background image, with digital clock on top, and small-to-big circles in the centre, circulating Unread/Notifications/Talk Time. Each of these parts appear and fade each after the other, while changing the colour of the circles in the background and the placement of the little ones. From the Welcome screen, the user could swipe to any of the four directions: up for notifications, left for the app menu, swipe from the right to launch the previous app, and swipe from the bottom to display the operations menu. Also, the user would be able to launch Voice Control by touching the bottom-right corner outside the interface, where the soft buttons would be on other smartphones. In the main menu, you could swipe far to the bottom and release to launch the Home Screen. The Ubuntu for Android project, as said, is the first step for this new phone OS. Developers will be able to create one app, with two interfaces: a smartphone UI, and, when docked, a desktop UI. The software would then be integrated with Qube, and Quickly development (as told in the OMG! Ubuntu's Google+ hangout). Full information about the phone and OS is currently available in Ubuntu's official page for the product . A Developer Preview was released in February 2013.
