What makes a phone a “Linux phone”?

Essentially, if a smartphone is powered by a Linux OS, it’s a Linux phone.

Technically, Android uses the Linux kernel too, but phones in this article also use FOSS software and modified Linux distros. Most phones here use the original (mainline) Linux kernel, not a heavily modified Linux kernel like Android uses.

Most of the Linux phones in this list use desktop-ready software. Convergence is the keyword here.

Most of the Linux phones here have a modular hardware design (easily replaceable parts) – although this is not a feature specific to Linux, it is a common feature among Linux phones.

Most Linux phones focus on privacy and security – just like most of the Linux desktop distros. Again, this is not a feature specific to Linux phones, but they do all focus more on privacy, so you might lose out on apps like Facebook and Google.

What you should know before buying a Linux phone

Before buying a Linux phone, it’s worth knowing:

  • Some Linux phones are just refurbished Android smartphones with a Linux mobile distro pre-installed on them. You can buy a cheap second-hand or refurbished smartphone and install Linux on it yourself, it will cost you a lot less. It’s up to you to decide if paying the extra price is worth the time you’d save and the support you’d get from the company. We didn’t include those kinds of phones in this list.
  • Although debatable, most of these Linux phones can’t be used as a daily driver and they can’t really replace your current daily driver. They do lack a lot of features and apps you’d need. They’re meant for developers and enthusiasts.
  • Linux phones lack a lot of the apps you’re used to. Some existing apps aren’t even that mobile-friendly.
  • If you’re not familiar with Linux and the CLI, they might not be a good fit for you.

Best Linux Phone – Our Top Picks

These are our top picks for the best Linux phones. There are more out there, but we only included these. It doesn’t mean phones that aren’t listed here aren’t good. The order of the phones is random, the first phone in this list doesn’t mean that it’s the best. They’re all somewhat different and each phone has a different target user group. You can’t go wrong with any of these phones.

Fairphone 4 is yet another smartphone with modular hardware. You can easily replace the battery, display, and most of the other hardware with a screwdriver. No special tools or skills are needed.

You’ll have to reflash and install postmarketOS yourself, which is why it’s in this section of our list. Once you install it, you’re pretty much set. Fairphones are and have been actively supported by postmarketOS.

Honorable mentions

We won’t go into detail for each of these phones, but these Android phones have great compatibility with postmarketOS:

What distro do Linux phones use?

This all depends on what Linux phone you’re buying. They use various distros – some phones even have an option to choose a distro.

Linux phone distros include, but are not limited to:

Some of these are technically not Linux phone distros, but a FOSS alternative to Android with a more Linux-friendly approach (ex: mainline Linux kernel). We’ll write a dedicated article to Linux phone distros, so subscribe and stay tuned.

Can any smartphone be turned into a Linux phone?

The short answer is: yes. The long answer is: depends. Some phones aren’t tested and aren’t supported by the Linux phone distros mentioned above. Your best bet is to check the OS list of supported devices and see if your phone is on there. If it is, then it means that your phone can be turned into a Linux phone. Choose the OS you want to use, and check their website/wiki for a list of supported devices. In most cases, your smartphone will be supported.

Why can’t a Linux phone be used as a daily driver?

It can – but chances are, it won’t be as good as your current daily driver. It all depends on how you use your smartphone and what you need it to do. App availability is pretty tough, even for desktop Linux distros. Mobile app compatibility for Linux is even harder to find. If you’re installing a Linux distro on an Android phone, there may be some compatibility issues, some features not working correctly, etc. Sadly, Linux phones are still not as developed and as mainstream as we’d all want them to be.

What apps can you use on a Linux phone?

There are many compatible apps out there, instead of listing them all here, we’ll refer you to this page. It’s a list of 334+ compatible apps with Linux phones. That page also links out to other resources and apps lists.

Can you use Linux on a smartwatch?

Yes, you can! Check out AsteroidOS. Pine64 also have their own smartwatch – PineTime. We might dedicate a new article to Linux smartwatches.
