Ubuntu Touch Explained: A Privacy-Focused Linux Mobile OS Alternative to Android

1. What Is Ubuntu Touch? A Free Mobile OS Alternative to Android

A “De-Google” Option Even for Smartphones

When it comes to smartphones, the vast majority of users today rely on either Android or iOS. However, in recent years, more users have begun seeking better privacy protection and a lifestyle that does not depend on Google’s services. In response to this demand, an open-source mobile operating system called Ubuntu Touch has been gaining attention.

Ubuntu Touch is a smartphone operating system based on Ubuntu, one of the most popular Linux distributions. It is often regarded as a “free and open alternative” to Android.

What Is Ubuntu Touch? Its Origins and Background

Ubuntu Touch was originally developed as part of Canonical’s vision to unify smartphones and PCs. Built on Ubuntu desktop technology, it was announced in 2013 as a fully independent mobile operating system. However, development was suspended in 2017.

After that, a community group called UBports took over the project. Since then, Ubuntu Touch has continued to evolve through active community-driven development.

This makes Ubuntu Touch a unique project sustained not by a single corporation, but by a global volunteer community, embodying the true spirit of open source.

Why Ubuntu Touch Matters Today

In the 2020s, concerns about personal data protection and digital surveillance have grown rapidly. Android devices typically require a Google account, and many apps collect user behavior and search history.

Ubuntu Touch, on the other hand, is designed so that user actions and data remain on the device, without relying on services from Google, Apple, or other major corporations.

Unlike centralized app ecosystems such as Google Play or the App Store, Ubuntu Touch uses an independent app platform called OpenStore. This allows developers and users to distribute and use software freely, without censorship or excessive regulation.

Prerequisites Before Getting Started

Compared to mainstream smartphone operating systems, Ubuntu Touch is not yet at a “plug-and-play” level for everyone. Supported devices are limited, and some functions—especially carrier-specific features such as calls and SMS in Japan—may have restrictions.

That said, Ubuntu Touch offers exceptional freedom and transparency, making it a compelling option for developers, privacy-focused users, and anyone pursuing a more independent digital life.

2. Overview of Ubuntu Touch and Its Development History

From Canonical to UBports: The Project’s Journey

Ubuntu Touch originally started under Canonical, the company behind Ubuntu Linux. In 2013, Canonical also announced the “Ubuntu Edge” project, aiming to merge desktop and mobile experiences.

Due to funding difficulties and lack of commercial success, Canonical withdrew from Ubuntu Touch development in 2017.

To keep the project alive, a volunteer-driven community called UBports stepped in. They inherited the source code and continue to develop, maintain, and expand Ubuntu Touch. Today, the UBports Foundation serves as the official organization behind the project.

Community-Driven Development by UBports

UBports is not a corporate entity but an open global community of developers and users. Anyone can contribute. Source code is published on GitHub, and development discussions take place through regular meetings, Telegram groups, and forums.

Ubuntu Touch also receives regular OTA (Over-The-Air) updates, delivering security patches, feature improvements, and support for new devices.

The project is developed not for commercial profit, but as an operating system designed to protect user freedom and privacy.

The Strength of Being Ubuntu-Based

Ubuntu Touch is built on Ubuntu 20.04 LTS (Long Term Support). This ensures overall system stability and long-term availability of security patches and kernel updates.

Using an LTS base provides excellent reliability and longevity, allowing users to trust the OS for long-term use compared to many short-lived mobile platforms.

Why Ubuntu Touch Still Matters

In a market dominated by Android and iOS, Ubuntu Touch may appear niche. However, its continued existence is driven by a clear demand: users who genuinely value privacy and control.

For those concerned about data collection and corporate-controlled ecosystems, Ubuntu Touch offers one of the few smartphone environments that can be fully controlled by the user.

3. Key Features and Advantages of Ubuntu Touch

A Fully Open-Source Mobile OS That Prioritizes Privacy

The greatest strength of Ubuntu Touch is its design philosophy, which places user privacy above all else. Unlike Google or Apple smartphones, Ubuntu Touch explicitly avoids collecting user activity data or personal information.

No Google account is required, there is no automatic cloud synchronization, and no built-in advertising or tracking.

As a result, Ubuntu Touch has emerged as a powerful alternative for those seeking to take back control of their smartphones in an era of digital surveillance.

Lomiri: An Intuitive and Elegant User Interface

Ubuntu Touch uses a unique user interface called Lomiri (formerly Unity8). It is designed to adapt seamlessly to both smartphones and PCs, featuring a gesture-based, responsive layout.

• App switching via edge swipes
• Simple and efficient multitasking
• A layout closer to desktop environments

This provides a distinct user experience different from Android and iOS, becoming highly efficient once users become familiar with it.

Independent App Distribution via OpenStore

Instead of a centralized app marketplace like Google Play, Ubuntu Touch uses the community-driven OpenStore. Many apps are lightweight, free of ads and trackers, and anyone can develop and publish applications.

Apps are distributed using the .click package format, each running in a sandboxed environment, offering a high level of security.

4. Key Differences Between Ubuntu Touch, Android, and iOS

Fundamentally Different Software Philosophies

The difference between Android, iOS, and Ubuntu Touch goes far beyond UI or usability. The most significant distinction lies in their underlying philosophy toward software.

Android and iOS are provided by major corporations—Google and Apple—and users are deeply integrated into their ecosystems. App distribution, OS updates, backups, advertising, and data collection are all managed under corporate control.

Ubuntu Touch, by contrast, is built on open-source principles and aims to provide maximum freedom and transparency to users. It is maintained by the non-profit UBports community, and its source code is fully open and modifiable.

Development direction is often decided with community input, prioritizing user choice over corporate profit.

App Distribution and Degree of Freedom

On Android and iOS, apps are obtained through official marketplaces such as Google Play and the App Store. While these stores offer strong security, they also require compliance with corporate review policies and censorship, limiting freedom.

Ubuntu Touch uses an independent app store called OpenStore, where anyone can freely publish applications. Most apps are free of ads and trackers, often reflecting the developer’s personal values.

Additionally, sideloading apps is simple, further demonstrating the platform’s high level of freedom.

System Updates and User Control

On many Android and iOS devices, OS updates depend heavily on manufacturers. After several years, even security updates may stop.

With Ubuntu Touch, supported devices can receive updates at the user’s discretion. OTA updates provided by UBports allow users to install the latest features and security patches without concern for commercial discontinuation.

System-level customization—such as unlocking bootloaders or replacing kernels—is also permitted, providing a highly flexible environment for technically skilled users.

Approaches to Data and Privacy

Android and iOS offer convenient features like cloud sync and voice assistants, but these rely on large-scale personal data collection.

Ubuntu Touch follows the opposite philosophy. Data is stored locally by default, and external communication is minimized. No account creation is required during setup, and there is no built-in cloud synchronization.

For users who want full control over their data, Ubuntu Touch stands out as an ideal solution.

5. Supported Devices and How to Choose One

Not Compatible with All Smartphones

Ubuntu Touch is not an OS that can be installed on every smartphone. Only specific supported devices are compatible.

This is because Ubuntu Touch requires device-specific drivers and optimizations. Supported device lists are continuously updated, so checking the official UBports website before installation is essential.

Common Installation Issues and Solutions

7. Setting Up a Japanese Language Environment

Does Ubuntu Touch Support Japanese?

Ubuntu Touch is a multilingual open-source operating system, and basic Japanese display is supported by default. During the initial setup, Japanese can be selected as the system language.

However, Japanese text input (IME) is not fully supported out of the box. To comfortably read and write Japanese, additional configuration or apps are required.

How to Enable Japanese Display

After installing Ubuntu Touch, you can switch the system language to Japanese by following these steps:

1. Open the “Settings” app
2. Select “Language & Text”
3. Choose “Japanese” under “Language”
4. Reboot or log out to apply the changes

This will localize the system UI and supported apps into Japanese. Some unsupported apps may remain in English.

How to Enable Japanese Input (Mozc)

Because Ubuntu Touch does not yet provide a fully integrated Japanese IME, the most common solution is to use Mozc, the open-source version of Google Japanese Input. This approach is intended for intermediate to advanced users.

Currently, there are two main methods:

① Using Android Japanese IMEs via Waydroid

By installing Waydroid (an Android container environment), you can use Android-based Japanese IMEs such as Google Japanese Input or Simeji.

• Pros: Relatively easy setup, works across Android apps
• Cons: Not usable in native Ubuntu Touch apps

② Running Mozc in a Libertine Container (Experimental)

Ubuntu Touch provides Libertine, a container system for running desktop Linux applications. Mozc can be installed inside a Libertine container.

• Create a Libertine container (Settings → Developer Settings)
• Install Mozc-related packages (CLI required)
• Test input in desktop apps such as text editors

This method can be unstable and is not yet considered production-ready.

Compatibility with Japanese Mobile Carriers

Ubuntu Touch is primarily developed around Western communication standards, so special attention is required when using Japanese carriers.

• Use a SIM-unlocked device
• docomo networks are generally stable; SoftBank and au may lack VoLTE support
• Manual APN configuration is often required

APN settings can usually be added manually in the cellular settings. If automatic configuration fails, refer to your carrier’s official APN documentation.

Summary of Japanese Language Support

While Japanese support in Ubuntu Touch is not yet “perfect,” it can be made fully usable for daily tasks with some configuration.

8. Real-World Usage and Limitations

Core Functionality Varies Significantly by Device

Ubuntu Touch includes all essential smartphone features such as calls, SMS, Wi-Fi, and web browsing. With officially supported devices, overall stability is generally high.

On recommended devices like the Pixel 3a or Volla Phone, users typically report:

• Calls and SMS: Fully functional
• Mobile data: Works after APN setup
• Wi-Fi and Bluetooth: Mostly stable
• Camera: Still photos supported; video recording may not work
• GPS: Accuracy varies by device
• Apps: OpenStore apps run smoothly

That said, device-specific differences are significant. Checking device reports on the UBports website or forums before installation is strongly recommended.

Still Not on Par with Android or iOS

Because Ubuntu Touch is community-developed, its feature completeness and app ecosystem lag behind commercial operating systems.

Common limitations include:

• Limited camera features such as video recording or HDR
• Commercial apps like Google Maps or LINE unavailable natively (Waydroid required)
• Smaller app selection with simpler functionality
• Battery optimization still underdeveloped
• Notification reliability varies by app

Ubuntu Touch should be viewed not as a direct Android replacement, but as a mobile OS built on a different value system.

Expanding Practicality with Waydroid

Waydroid helps compensate for many limitations by allowing Android apps to run within Ubuntu Touch.

• Messaging apps such as LINE or Messenger
• Google Maps and YouTube
• Android-based Japanese IMEs

However, Waydroid also has limitations:

• Incomplete file sharing between Ubuntu Touch and Android environments
• No hardware acceleration; performance may suffer
