The project was started by

History
The Ubuntu Touch project was started in 2011.
Mark Shuttleworth announced on that by

es), but to date has only been supported by vendors on a few smartphones, one tablet and a number of third-party devices which hobbyists have ported the operating system to. The initial goal set by Shuttleworth for Ubuntu was to reach full convergence (same platform and libraries on all devices). The Ubuntu platform for phones was unveiled on .
The Ubuntu Touch Developer Preview was released on .
On 22 July 2013 Ubuntu announced a crowdfunding campaign for the
Ubuntu Edge smartphone that would run Ubuntu Touch, but it did not reach its funding target.
Canonical released Ubuntu Touch 1.0, the first developer/partner version on 17 October 2013, along with Ubuntu 13.10 that "primarily supports the
Galaxy Nexus and
Nexus 4 phones, though there are images available for other phones and tablets", and released a "relatively 'stable' build for wider testing and feedback" on 17 April 2014, along with Ubuntu 14.04. A preview version of the software is available for installation on certain additional Android handsets including the

Ubuntu Touch was released to manufacturers on 16 September 2014.
BQ Aquaris E4.5 Ubuntu Edition, the world's first Ubuntu-based smartphone went on sale in Europe on 9 February 2015.
In April 2016, the world's first Ubuntu-based tablet, the
BQ Aquaris M10 Ubuntu Edition, was released.
In August 2016, OTA-3 was announced to support
Android 6.0 BSP.
In August 2018, UBPorts released its OTA-4, upgrading the Ubuntu Touch's base from the Canonical's starting
Ubuntu 15.04 "Vivid Vervet" to the nearest, current long-term support version
Ubuntu 16.04 LTS "Xenial Xerus".
Ubuntu for Android
Ubuntu for Android was a variant of Ubuntu designed to run on
Android phones. It was expected to come pre-loaded on several phones.

Lock screen
When Ubuntu Touch is turned on no
lock screen immediately appears, as applications will prompt the user to unlock if necessary when they are opened. The centre of the "Welcome Screen" is a visualisation of activity on the device. It shows the user's status and recent events on the welcome screen, completed with a design around the circle which reflects activity on the phone over the preceding month.
Included applications
Ubuntu Touch includes core applications such as a calculator, an e-mail client, an alarm clock, a file manager, and even a terminal among others. Twelve or more core applications are currently being developed. Several Ubuntu Touch applications work on the desktop as well, including Morph Browser, Calendar, Clocks, Gallery, Notes, Reminders, Terminal, and Weather.
Side stage
Side stage was introduced in 2013 and allows users to run both "tablet apps" and "phone apps" side by side, resizing each on the top as and when you need to see more of them.

Shuttleworth: Ubuntu tablets won't be as "jarring" to users as Windows 8
". ''Ars Technica'', 19 February 2013. Accessed 27 February 2013. It aims to "go even further" with the idea of multitasking, allowing screen space to be divided in this manner. Examples shown in the announcement video included a notes app being used alongside a web browser, and a user swiping from the right edge to bring a mobile version of the Facebook app into view over a playing video.
Design
Users can access the whole system by swiping from the edges of the screen. A short swipe from the left edge allows for instant access to applications pinned to the launcher, while swiping all the way across reveals the home scope, which can be set by the user. This menu is available from the home screen and any running app.
Ubuntu Touch's multitasking is accessed by swiping the finger from the right edge of the screen to the left, which switches to the previous application (short swipe) or shows all open apps (long swipe). Swiping up from the bottom is used to show or hide tools specific to the app being used, which gives Ubuntu Phone the ability to run applications with a large, uncluttered canvas by default.
Target market
Mark Shuttleworth, the founder of the company Canonical Ltd., believed that Ubuntu for phones will first find a niche in countries where Ubuntu is well known; more specifically, developing markets such as India and China where computers have Ubuntu pre-installed. However, the success of Ubuntu Phone in these markets is difficult to predict.

Requirements
Hardware
Ubuntu Touch requires that a system's
CPU support certain hardware features.
Software
Ubuntu Touch can be installed on a number of phones that originally appeared with Android. It is necessary for these devices to offer an open source tree, so that the drivers can be recompiled for the new OS.
Ubuntu Touch uses
Halium in order to communicate with the hardware using Android drivers.
In 2023, UBPorts argues that "Halium has 95% contributions from us only"

Adrian Covert, writing for
CNN on , predicted that the operating system will not gain wide use, stating, "carving out a niche in the seemingly unshakable mobile space—ruled by the Android-and-Apple duopoly—still requires a critical mass of users and a lively ecosystem of app developers.

Joey Sneddon of ''OMG! Ubuntu'' disagreed with Covert's assessment, writing, "commentators like Covert are missing the point. See, Ubuntu Phones aren't really going to claw much market share away from Apple or Google. And this neat 'dock your phone and use it as a desktop' feature, whilst innovative, won't be the main lure for many

..But on first impression I'm hugely taken with Ubuntu Touch. It's elegant, thoughtful, and versatile, while remaining beautifully straightforward.
..it's by far the strongest potential rival to Android, iOS, and Windows Phone. In fact, I prefer it to iOS, which long ago lost its shine, and heck, maybe even to Android, too. Fingers crossed that manufacturers and phone carriers get behind it, because I'd happily lay down my own cash for an Ubuntu Touch phone."

Firefox OS has lined up behind it. But once put to a vote, Ubuntu Touch was the clear winner, with Firefox OS the runner-up. The team thought that Ubuntu Touch, the tablet version of which we got our hands-on for the first time at MWC, feels more like the complete package at this point.

Jesse Smith from
DistroWatch Weekly reviewed the Ubuntu Phone in Meizu Pro 5 lauding the price, interface, responsiveness and frequency of updates, calling it a "pleasant phone and communications experience" and distinguished it as a user-oriented device as opposed to Android's application-oriented nature and noted that it would be more likely to appeal to those interested in technology—Linux fans in particular—but was too new to appeal to the public at large. This was due, in part, to the limited selection of phone apps, partially due to the small size of the market, but stated that

Meizu MX4 Ubuntu Edition went on sale in China, becoming the second Ubuntu phone. On 9 June 2015, launched another device running Ubuntu Touch, the
Aquaris E5 Ubuntu Edition. The first ''tablet'' released was the
Aquaris M10 Ubuntu Edition; it was announced on 5 February 2016 and made publicly available two months later. In April 2016, the same month as the Aquaris M10, the
Meizu PRO 5 Ubuntu Edition was released. During this time period, BQ was also working on the first 'Convergent' Ubuntu Phone and the planned launch date was initially 2015 then pushed back to 2016.
In 2018,
Purism and the UBports Foundation began collaborating on making Ubuntu Touch available for the
Librem 5. The
PinePhone from
Pine64 was made available for preorder on 15 November 2019 with support for Ubuntu Touch along with many other
FOSS mobile operating systems. With the release of OTA-15 in December 2020, Ubuntu Touch began supporting the FX Technology Ltd. F(x)tec Pro
1 (2019) and Pro
1 X (2022)
phones.
The Volla Phone from Hallo Welt Systeme UG launched with official support for Ubuntu Touch in December 2020 as well (identical with Siemens GigaSet GX290).
Ubuntu Touch also supports Pine64 devices, such as the PinePhone, Pinephone Pro, and PineTab/PineTab 2 devices.
