PureOS/Phosh supports GTK, Qt/QML and web apps, which can be downloaded through the PureOS Store with planned badges for freedom, privacy, security and ethical design. Anbox can be installed to use Android apps.
● List of apps: 1, 2, 3
Where assembled Shenzhen, China ● DevKit: San Diego area, California,
● Librem 5: Shenzhen, China,
● Librem 5 USA: Carlsbad, California
Security & Privacy ● All chips use serial protocols (USB 2, SDIO, UART, I2C) that don’t allow direct memory access (DMA).
● All code in the root file system can be audited except 3 Realtek WiFi/BT firmware files.
● Ubuntu Touch sandboxes apps according to their AppArmor config file to specified directories and hardware access has to be authorized by the user or AppArmor.
● All chips use serial protocols (USB 2.0/3.0, SDIO, UART, I2C) that don’t allow direct memory access (DMA)
● All code in the root file system is FOSS and can be audited.
● Sandboxing of apps with flatpack and bubblewrap.
End-to-end encryption for messaging over XMPP (and Matrix as well?).
● 3FF smart card slot (2FF in Birch & Chestnut) and 80MHz Cortex-M4 STM32L432KC controller, so an OpenPGP card can be installed for secure cryptographic operations. (Future plans to use free firmware in Cortex-M4.)
Software kill switches to turn off GNSS while using cellular modem and turn off individual sensors.
● Publishes schematics and x-rays and will offer anti-interdiction services to detect tampering and inserted spy chips.
Looking into implementing the Librem Key for tamper-evident booting.
Other features ● RGB status LED.
6 pogo pin connector to I2C bus, so that mods can be added by changing the back cover.

(Can chain boot from microSD with jumpdrive after USB boot.)
FCC certification Granted 2020-05-08 Granted 2021-07-22 (with BM818)
Longevity & Fixability ● Promises to produce the phone for 5 years.
Adding hardware to mainline Linux kernel so easier to support long-term.
● Battery (same size as the Galaxy J7) can be bought from many sources.
● No glue and easy to disassemble with screwdriver.
● Sells economical replacement parts.
● Outsourcing the OS to many communities means there will always be some group providing software updates.
● Promises “lifetime support” in software updates.
● Designed to avoid planned obsolescence
● NXP promises to produce the i.MX 8M Quad until Jan. 2033 so can expect updates.
● No glue and only Philips screws, so easy disassembly, but screen and frame are one unit.
● Sells replacement battery & BM818 modem.
● CTO Nicole Faerber says "since we are in direct contact with the factory we can (and will) stock spare parts and will try find ways to make most of the parts replaceable. But I can not promise this for all and everything."
● Upstreaming code (1,2,3) when possible for better long-term support.
● WiFi/BT and cellular modem can be upgraded to support different standards and regions, but not 5G due to increased power requirements & different mmWave antennas.
Free/open source software All FOSS in the Linux file system except 3 proprietary firmware files in /lib/firmware/ for Realtek RTL8723CS WiFi/Bluetooth. There is optional auto-focus firmware for the OmniVision OV5640 back camera, but it is not used by any of the ports. Goal to be the first phone to receive the FSF’s Respects Your Freedom certification for 100% free software that executes on main CPU cores. There will be proprietary firmware in components (Wi-Fi, cellular baseband, etc.) which don’t need to be updated and proprietary code to initialize DDR4 by U-Boot will be moved to a separate SPI Flash chip and executed on the Cortex-M4F core. Will have binary blobs, but no proprietary firmware will have memory access. According to the FAQ, Necunos is considering trying to obtain FSF’s Respects Your Freedom certification, so probably only has blobs for U-Boot that can be moved to a separate ROM.
Free/open source hardware PINE64 publishes the PCB schematics in PDF (v1.0 Dev, v1.1 BraveHeart, v1.2 CE: UBports, v1.2a CE: postmarketOS), PCB silkscreens, and 3D .stp file for the back cover for 3rd party production of mods and cases, but there is no free/open license to reuse or modify them. The PCB schematics in PDF (DevKit, Birch, Chestnut, Dogwood, Evergreen) are published under the GPL 3.0+, as required by Purism’s SPC charter, as well as the KiCAD schematics files for the DevKit, which was designed with free software tools.
● CEO Todd Weaver says that Purism needs to recover its development costs before releasing the Gerber files, which they are “thinking about releasing in a time capsule” of “3 years, 5 years, something like that.”
● Purism released the OpenSCAD and STL files for the case, battery, modem and screen mount.

● First phone to promise lifetime software updates.
● Third phone maker (after OpenMoko and Golden Delicious) offering free/open source PCB schematics.
Reasons to buy ● Economical and good value for money, because software development is outsourced to the community (volunteers), adapted from its existing A64 board design, and selected older components with existing mainline Linux support.
● Linux phone most ready for daily use today with 24 hours of battery life with the modem on.
● PINE64 designs its hardware in collaboration with the community and CEO TL Lim responds to community feedback.
● Pine64 supports community software development with a $10 donation per phone to the OS projects and the hardware helps projects attract more volunteers.
● Support a company that is transparent, community-based, and doesn’t over-promise in its PR.
● Good for tinkering and DIY projects with schematics and larger community for help.
● Good for creating mods with I2C pogo pin connector, .stp back cover file, and 5 years production on a common A64 platform shared by the PinePhone, PineTab and PINE A64-LTS.
● Proven track record of supplying economical replacement parts.
● Commitment to 100% free software and one of the few companies that produces new hardware and aligns with the FSF.
Social Purpose Corp.[1,2] that promotes digital rights to privacy, security and freedom over profits and produces free software and free hardware.
● Goal to drive change up the supply chain by working with good component suppliers that take feedback and will work for free software compatibility.
● Help pay for development costs of GTK/Phosh and adaption of GTK desktop apps, so that the GNOME ecosystem can be used on mobile devices, which lowers the long-term maintenance costs.
● Help pay for new components (i.MX 8M, LM3692x, MAX17055, LSM9DS1, BQ25890) to be added to mainline Linux.
● Trying to fight planned obsolescence with 1. lifetime software updates, 2. upstreaming code to parent projects for long-term support, 3. using a well-maintained GTK/GNOME stack, 4. replaceable WiFi/BT and cellular modem on M.2 cards, and 5. an SoC manufacturer that promises production till Jan. 2033 and contributes to the mainline Linux kernel for future updates.
● Better privacy with accessible hardware kill switches with lockdown mode to turn off all sensors, software switches, an OS and web browser preconfigured for privacy, and optional Librem One web services, and optional AweSIM privacy cellular plan.
● Better convergence for use as a PC due to use of existing GTK/GNOME desktop software, faster USB 3.0 port, better graphics performance and better video out.
● The i.MX 8M Quad is better than the Allwinner A64: 30% faster CPU clock speed, 140% faster RAM standard, 140% better OpenGL performance, USB 3.0 and support for higher resolution cameras.
● Long-term goal to produce phones for non-technical users that are preconfigured for privacy/security and apps from the PureOS Store with easy-to-understand badges and Librem One web services, so normal users don’t have to give up convenience to get privacy and freedom.
● Assembled in Finland.
● Extreme focus on privacy/security and company has provided workshops for journalists to protect their privacy.
● Can provide customized security phones for corporate clients.
● Good community collaboration and donation to the OS project providing the software for each phone sold.

Future versions Original specs said 16-64 GB storage, so maybe a future version with 64GB.
● The next SoC for the phone is the RK3566, based on the Quartz64 SBC.
Fir batch with the 1.8GHz i.MX 8M Plus (Samsung 14nm LPC FinFET) is planned after Evergreen.
● A tablet based on the Librem 5’s design is planned “once we have the Librem 5 in a stable state, i.e. continuously shipping.”

* All specs for the SoC in italics are what the SoC supports, but there may not be FOSS drivers, configuration, thermals, or other hardware to use it.

HDMI alt-mode over USB-C is generally not supported by the electronics industry. To connect to an HDMI monitor, use a USB-C to HDMI adapter cable (all such cables on the market contain circuitry to convert from DisplayPort alt-mode to HDMI).

ª Listing the max photo and video resolutions supported by the image sensors, but these will be limited by the processing power of the SoC, the speed limit of the camera interface, and the capability of the FOSS driver and camera app.

The A64 in the PinePhone has a hardware video encoder for H.264 1080p at 60fps, but it isn’t supported by the free drivers. Martijn Braam at postmarketOS has created a Python script to take photos and 1080p video at 15fps using software encoding. The A64 Datasheet says the camera’s “CSI” interface supports up to 1080p at 30fps video, but it is actually an 8-bit parallel interface, and PinePhone firmware developer megous comments:

1080p@30fps is not attainable on the parallel interface, at least not with the cameras that are in the phone. It would require ~120MHz clock, and communication starts to break down at around 60-70MHz.

The Samsung 13MP image sensor in the Librem 5 is capable of capturing 4K video at 30fps, but the i.MX 8M Quad has no hardware video encoder and its documentation indicates that it is only capable of encoding 1080p video at 30fps in software. The Purism developers are still working on kernel support for the front and back cameras. Purism created a mockup of a future camara app for the Librem 5, but will probably have to adapt the Megapixels app, which was designed for the PinePhone.

Thanks! Wow, now the L5 looks like a great deal compared to the others (it already is). :stuck_out_tongue:


Thanks for catching that. I have corrected it.

Wow! Great phone that Librem 5. Glad I ordered one.


So also the wifi will have blobs? I understand about cellular to be isolated but i don’t think wifi could be isolate too, or i’m wrong?

Purism is controlling the RS9116 over SDIO 2.0, so no direct memory access like with the PCIe bus (which most other devices use to access Wi-Fi/Bluetooth). Purism says that it won’t have any blobs in the Linux kernel or U-Boot, but there will be proprietary firmware installed in the components.


Thank you very much for the comparison, it is very helpful.

I didn’t know the NC_1, but I don’t see it as a very interesting device. In addition, the price is abusive. Why does it cost so much (much more than Librem 5)?

My idea is to buy the Pinephone when it is on sale this year. The price is very attractive and is a good phone to start messing with.

In the case of Librem 5, I will wait for it to go on sale when it is already manufactured. Maybe I’ll wait for a more powerful second version.

This Necunos shouldn’t be on this comparison list. Or the title should be worded differently.
No basebands for “security reasons”? Ok, then it’s not a phone. They can call it “Communicator” / WiFi VoIP Media Player, etc.

I agree that it is misleading to call it a phone, given that it looks like a smartphone. Necunos’ press release calls it a “smart mobile device”

However, a few people have discussed removing the cell modem from the Purism 5 to make it into a WiFi only device. Purism calls their phone a IP-native mobile handset, which means that while the cell modems are designed to do normal cell phone voice calls and text, we could just use the cell modem for data only and receive voice calls via VoIP over the top of the cell data network and through WiFi when available.

“Linux smart mobile handsets” might be a more accurate label, although it sounds unconventional and wordy.


The first production run for the NC_1 was 500 devices, whereas Purism is producing 10k, so you have a lot more overhead costs per unit, plus Necunos is assembling in Finland, which is very expensive compared to China. I think that the people who pre-ordered the NC_1 want a mobile Linux device company focused on security to exist in Europe. If Necunos doesn’t manage to ship soon, however, I can’t see the company managing to survive, because Purism will take its niche market.
However, Necunos plans to also offer a custom commercial version of the NC_1, and Necunos might be able find enough companies that have special security needs and need customized devices.

I predict that the second version of the Librem 5 will have more RAM and Flash memory, but it will probably use the same SoC. I don’t think that Purism will switch to the i.MX 8M mini despite the fact that it is more energy efficient, because it has a less powerful GPU and little video out, so it won’t work well for convergence as a PC, which is one of the goals of the Librem 5.

Maybe Purism can switch to Rockchip in the future now that the Lima drivers have improved, but it sounds like the future RK3588 won’t use the standard Mali GPU, so that probably won’t be a possibility. As I see it, Purism is probably stuck with the i.MX 8-series for the next couple years, so we have to pray that NXP will decide to either offer the i.MX 8M mini with a more powerful GPU/VPU or do a die shrink on the i.MX 8M Quad.

If the better version of the PinePhone with 3GB RAM 64 GB Flash costs $250 or $300, I think that a lot of people will order it, but PINE64 expects users to solve a lot of their own problems. It will be a great DIY phone, but probably not a good phone for people who aren’t tinkerers.

The Librem 5 will be a thick brick (and probably require frequent charging), so people who want a normal sized phone will have to go with the PinePhone. PINE64 doesn’t have many software developers and is relying on the community to provide a lot of the software, so I expect that using the PinePhone will be a real challenge in the first year.

Here is how I would summarize it:

  • Outdated SoC
  • Low resolution camera and can’t be improved due to the SoC
  • Economical
  • Software will be very rough and don’t expect much hand-holding from the manufacturer, but can get help from the communities providing the software
  • Slim case, so easier to carry

Librem 5:

  • More modern SoC (but still underpowered compared to today’s Snapdragon, Exynos and Helios)
  • Acceptable camera
  • Software will be rough at first, but it will improve, so will probably be good enough that a normal person can use it as a standard phone in a year or two.
  • Very thick, so only for people who don’t mind the large size
  • First phone in the world with replaceable Wi-Fi and cellular baseband

These go to a different category - especially from software perspective as they are not open to user (although there seems some effort to make Google stay away): Bittium’s (another Finnish secure coms firm) Though Mobile 1&2. What I find interesting, are some of the HW decisions. Physical aspects are impressive (water and shock proof), but cameras are slightly lesser quality etc. But the main similarity (and reason to mention here): physical button to affect sensors: a “privacy mode” that (if I’ve understood correctly) reduces accuracies (may not turn them off?). Interesting idea to compare to.


The Librem 5 at $699 looks like a steal compared to 1550€ for the Bittium Tough Mobile 2. According to the description, the “privacy button” provides: “Hardware-based privacy mode for disabling microphones, cameras, Bluetooth, and reducing sensor sensitivity”.

If they went through the trouble of adding a separate Bluetooth chip, why not use a separate Wi-Fi/Bluetooth chip?


Doesn’t it just :slight_smile: But I’m pretty sure they target governments and affiliated orgs.

But I couldn’t find any specifics either on the buttons boyond that.

It’s fine for a first gen, i hope a librem5 v2 will be completly open

Unfortunately that is not possible. The only processor that doesn’t require a binary blob to set the timing in the DDR PHY is the POWER 9. There is no way to get that chip into a phone. It looks like SiFive’s RISC-V mobile processor (which is supposed to be ready in 2 years) will be even worse in terms of binary blobs since it uses a PowerVR GPU. The Rockchip RK3588 doesn’t look like it will use a standard Mali GPU, so there won’t be any free drivers.

Nobody makes Wi-Fi, Bluetooth, cellular modem or GNSS without proprietary firmware. The best that you can do is put it on a separate chip and use a bus that doesn’t provide Direct Memory Access (DMA). This stuff is so locked up in patents, that I doubt that any manufacturer will ever make any of these components with free firmware and reverse engineering the proprietary firmware is incredibly hard. If anyone tried to produce an open hardware LTE modem, they would be sued out of existence and the patent holders would never allow them to license the patents if they wanted to publish the code. Maybe you could take all of them to court and force them to license the patents under the FRAND laws, but the legal fees would drive you into bankruptcy.


Like a steal?

it seems to me that your affirmation is rather exaggerated, considering the commitment to something totally new, the use of isolated hardware, the creation of non-existent software.

Patents eventually expire.

Patents do expire. When they do, the cell technology will be taken out of service. So it will not be possible to use those expired patents unless you start your own network and license the spectrum for use with obsolete technology. The only way to avoid this is to innovate in the open, and let the open technology replace the proprietary via superior functionality.


20 years is a LONG time in a technology context. sheesh …

Agree needs better name. How about gnu-phone? (gphone for short). … Because it was the GNU project that started this all off. Linux only came later.
