4 Best Linux Phones for Privacy in 2021

As the demand for internet connectivity keeps growing, so has the need for data privacy. In order to efficiently deliver their services, there is a tendency for some companies to collect and store personal data from their users. Sadly, some applications and platforms violate their users' privacy by leaking their data which finds its way to other platforms. This can often lead to users being inundated with adverts or worse still, data breaches

Linux-based phones are built on free and open-source software. Going for the privacy-focused phone will mean that may lose out on some of the first-party applications offered by Google or Apple.

In this tutorial, we have recommended some of the top Linux phones in 2021 that guarantee a user's privacy.

1. Librem 5

Now let's look at its features that ensure privacy. The Librem 5 physically isolates the cellular modem from the CPU and main memory, which is crucial for protecting the rest of the phone, including the operating system, from cellular provider software and towers. In addition, it provides three hardware kill switches to physically disconnect cellular with the first switch, WiFi/BT with the second, and Camera/Microphone with the third. There’s also a lockdown mode when all three switches are switched off.

With further development, the Librem 5 phone will be able to run web applications in addition to its native applications. This will allow its users to run the most common daily applications through the web browser. Purism intends to sandbox and isolate these applications from the OS, so they won't be able to see what's going on in other apps or access areas you haven't specifically granted access to.

Its hardware specifications include:

  • 13MP rear camera and 8MP front camera
  • a user-replaceable 4500mAh battery
  • 32GB secondary storage
  • 3GB RAM
  • Display: 5.7” IPS TFT screen @720 x1440

  1. The Pro1x has only a Snapdragon 662 SoC which is a dramatic downgrade from a 835.

    Especially for the price that fxtec are asking for the device.
