How to Use Your Android Phone to Replace Your Desktop PC

Christian Cawley 24-11-2016

Most Android smartphones today are more powerful than we give them credit for.


You use your phone for email, you type up notes, you probably do some image editing, you play games — and so much more. For all intents and purposes, this smartphone sitting in your pocket is a personal computer. It’s arguably as powerful as many devices sitting on desks in offices around the world. So why not use it to replace your desktop PC?

The Continuum and Convergence of Smartphones

The increased power and flexibility of smartphones means that we’ve now reached a stage where they can realistically replace our PCs. It’s already happening for Windows 10 Mobile, with Microsoft Continuum Continuum: Switch Between Windows 10 Desktop & Tablet Mode Windows 10 recognizes your hardware and instantly chooses the best display mode. When you connect your Windows 10 Mobile to a larger screen, you'll get a PC-like experience. That's the smoothness of Continuum.

Support for Bluetooth keyboards and mice means that you can sit at a desk with your phone beside you, its contents displayed on a monitor in normal Windows 10 style. Then you can type, browse the web, or do any other computer-based tasks — and the phone will still let you answer calls.

Ubuntu Touch Convergence Activate

It isn’t just Microsoft offering this sort of technology, either. Canonical’s Ubuntu Touch mobile platform can also convert a compatible device into a compact portable PC with its Convergence system How to Turn Ubuntu Phone Into a Desktop PC With Convergence Newcomer to the mobile space, Ubuntu Phone, has its own mobile-to-desktop software. If your device is compatible, and running the OTA-11 update (or later), you can turn your phone into a PC. Read More .


While iOS is some way behind, there’s now an option for Android called Maru OS. This is a custom distro optimized for desktop use, offering a similar (albeit wired) experience to Continuum and Convergence.

Getting Started With Maru OS

It sounds pretty good, but Maru does have a downside.

At this stage, you need to understand that the current contents will be completely wiped, so if there are any songs, photos, movies, or other data you wish to keep hold of, you’ll need to back these up first.

Install Maru With a Custom Recovery

Alternatively, just download it directly to your Android device; the download is 653 MB.

Fortunately, a couple of Play Store apps are available for you to install on your current Android device, converting it into a literal pocket PC with minimum fuss. No TWRP recovery or installers required here!

Leena Desktop UI [No Longer Available]

Once installed, you’re ready to run with Leena Desktop UI, but note that this is essentially a desktop-oriented launcher. If you’re already able to cast your Android device to a TV, then you’ll be able to use Leena.

Of course, you’ll need a Bluetooth mouse and keyboard, but once these are connected and you’re casting the Leena UI to your TV or monitor, you’ll almost forget you’re using a phone at all!

Andromium OS (Beta)

As you may have guessed, this solution remains in beta, but you can install it and try it out via Google Play. The usual Miracast dongle is recommended for your HDMI TV, along with Bluetooth keyboard and mouse, although Andromium OS is only half the story. If you prefer, a device called the Superbook is also available, a sort of empty laptop that you can plug your Android smartphone to.

Is an Official Option Coming?

Given the lead that Android took in wirelessly casting mobile devices to a TV via Chromecast, it’s odd that it’s lagging behind in the dynamic form factor/platform convergence that is taking place. But perhaps we’re wrong about that; perhaps Android will have a fully built-in desktop-casting option by Android 8.0.

    maruOS is awesome.
    with the new release you can start the unerlying debian without connecting it via HDMI
    so you can ssh into the debian-side of your phone or use VNC while you stil can use the android side as normal phone.
    (you could have taskwarrior installed and run it at work via ssh - when you finished carry it with you and use the android app - without syncing or cloud-fuzz)

    I've been interested in something like this for awhile, but none of these options do what I have in mind. I'm one of those, on-an-extremely-limited-budget-ppl, so I do not frequently buy devices.

    What it **seems** I should be able to do, is hold my tablet or PC in my lap, and wirelessly transmit to my BluRa player, a Panasonic DMP-BD85 (not new, but it has limited wifi capabilities), and just have my tablet/pc screen appear on the TV. I've done several searches over the years, and have not found a viable, solution.

    In this article, Leena looks like fun, but not sure it does what I want. I may check it out, if my tablet can support it.

    Thanks for a great article.
