I hope Ubuntu Touch can become the most viable alternative to Android for mobile devices.

It should be secure, respect privacy, and reject government censorship and surveillance.

In terms of system architecture, it should incorporate UI features from WebOS.

In terms of applications, I hope it supports web applications.

It should support unified communication.

I dislike Android because it's closed, increasingly sluggish, has a bloated design, a virtual machine mechanism, consumes a lot of power, has excessively high device requirements, pushes system junk, and isn't a true Linux distribution.

Can Ubuntu Touch and Sailfish OS merge?Simply put, can Ubuntu Touch absorb Sailfish OS's strengths to complement its own weaknesses, making app development simpler, faster, and more efficient while lowering the entry barrier?
My suggestion: Ubuntu Touch should never implement an Android compatibility layer.At the same time, it needs to optimize game performance!
The future focus should be on China. As long as Chinese developers are attracted to join, this system can definitely completely replace the lackluster Android. Our slogan: "Take down Android, defeat Apple!"
Ubuntu Touch
Cross-platform capability: Leverages the Ubuntu ecosystem, allowing attempts to adapt UT apps to desktop Ubuntu. However, there are no official toolchains—interface layouts require manual adjustments; ARM/x86 architecture support is community-driven only.
Development toolchain: No official dedicated SDK. Relies on Qt Creator (from Ubuntu Desktop) + compilation scripts/images provided by the UBports community. Device connection for debugging needs manual configuration, resulting in a high barrier for beginners.
Sailfish OS
Cross-platform capability: Official "Sailfish SDK" supports one-click compilation for phones, tablets, and even in-vehicle/embedded devices (Jolla's commercial use cases). Silica UI adapts to different screen sizes natively, minimizing cross-device adaptation costs.
Development toolchain: Official "Sailfish OS SDK" (customized based on Qt Creator) comes with an emulator, debugging tools, API documentation, and supports one-click deployment of apps to real devices/emulators. It also offers a visual UI editor, making it much more beginner-friendly.

Android is too rubbish. I don’t like Android. The virtual machine mechanism is very stuck, consumes hardware, and takes up too much system resources. It is not a real Linux. It is used by Google and the US government to monitor and collect users.
Can Ubuntu Touch be merged with Sailfish os?
Learn more about webos in terms of functions and interfaces.
System: Open source, allowing all mobile phone manufacturers to install and use it, and provide solutions. For your system, you only need to make the system safe, smooth, fast, and stable.
Create a unified app download and installation market, allowing developers to upload and sell their own apps for profit, and manage the apps well. They cannot be started in conjunction with each other like Android apps, wake up each other, and stay in the background to occupy system resources and push notifications.
There needs to be a good push system, it should be smooth and it doesn’t need to stay in the background.
The main purpose is to build an ecological market, and then gradually eat away at the junk Android. When mainstream apps come to the new camp, this OS will be successful.

Android is garbage.
Google officially announced that the Android operating system will no longer be open source.
Because it uses a virtual machine mechanism, especially in terms of resource consumption, and it's a closed system, not true Linux. Intelligence agencies have built-in surveillance capabilities that can transmit data back to the US for war and assassination purposes. Android is filthy, stained with blood, and iOS isn't much better.

It can support watches, TVs, phones, and Linux systems. I hope the open-source community will continue to choose open-source mobile systems based on existing Tizen/webOS/Sailfish OS/Ubuntu Touch systems. So, which has more potential? Choose one and build it into a true Linux.

Allow the installation of third-party applications,

Establish a unified national alliance, a unified app store review (prohibit auto-start/associated wake-up/background running),

Support multiple application package formats,

Stable, fast, energy-efficient, lightweight, and supports artificial intelligence.

Applications: Support more development languages/QML/JS/C++/HTML5/C/Java/Go

CPU: Support ARM64/x86_6/RISC-V

A true Linux system; mobile applications should also support desktop applications.

It doesn't use the Android virtual machine mechanism; all applications are natively recompiled.

To achieve this, the driver layer may not be open source.

It directly replicates the iOS UI design.

The system must be made freely available to all phone manufacturers, must always remain open, neutral, and free from government control, and must reject built-in eavesdropping and data transfer capabilities.

Phone hardware capable of running Android should be able to easily install this new Linux-based mobile operating system. Phone manufacturers should strive to achieve this.

Lessons learned:

Why did Windows succeed? Because it could be installed on any computer, so it succeeded.

Android followed this path, so it succeeded.

Why did Windows Phone fail? Why did copycat operating systems fail? Because they all broke away from the closed system of iOS, but ended up on a dead end.

It supports multiple programming languages, allowing more developers to more easily develop and port applications, gradually solving the application ecosystem problem and surpassing Android. More importantly, it targeted the Chinese market, followed by India, South Korea, Japan, Africa, Europe, and finally the US market.
