Pre-Launch Hype

Purism launched a crowd-funding campaign for the Librem 5 in 2017. Their promise then was that it would be a purely free software phone with "focus on security by design and privacy protection by default". They managed to raise a lot of money with their promises.

Purism announced a launch date of April 2019 on September 4th, 2018. The final specifications and a price of a hefty $649 was announced in July 2019. This price was later adjusted up to $699.

The phone is sold as "pre-order" with batches going out every few months. The state of the "pre-order" queue as of December 2019 is that a "pre-ordered" phone will be shipped "within 6 months".

Operating System

Purism's PureOS is a derivative of the Debian GNU/Linux distribution. The mobile versions of both GNOME and KDE Plasma are available. Purism story is that it is possible to connect the phone regular computer devices like a monitor, mouse and keyboard and use it as a regular desktop. A brief glance at the hardware specifications indicate that this would be a absolutely dismal experience.

The Modem

The Librem 5 uses a proprietary modem which runs black-box binary blob firmware. It is isolated from the phone's SoC for security.

Verdict, Conclusion and Review

The hardware specifications of this phone is that of a low-end $100 phone from when it was announced in 2017.

It is interesting that they have made a Debian based smartphone operating system. It is also interesting that Purism has made a phone where security and privacy are among the primacy concerns. This being said: The interesting software and the moral championship aspects aside: The hardware you get is absolutely not up to modern standards or yesterdays standards for that matter.

There is absolutely no way we can justify paying $699 for a model which may or may not arrive within 6 months so we can test it. We will not buy this phone and neither should you. We are not going to do any in-depth review of this phone and we don't have to do so to give you a good idea what this phone is like: Just look at the hardware specifications and the price-tag and draw your own conclusions.

The reason we are comparing it against the Redmi Note 8 when we list the Hardware Specifications above is not because the Redmi Note 8 is a great privacy-respecting phone; it's not a privacy-focused device. We are comparing the Librem 5 to it because the Redmi Note 8 is objectively a much better phone which provides a much better user-experience at $200 (for the 4GB/128GB variant). That's a whole $500 less than Purism is demanding for the Librem 5.

In all fairness to the comparison between the devices, Purism had the literally make a mobile operating system whereas for the Redmi Note 8 they are just porting it to Android. They time it takes to make PureOS run on a phone in a user friendly matter requires years of development whereas porting a device over does not.
