Mobiles currently in production

Model Hardware kill switches Modular smartphone System-on-a-chip (Soc) Baseband cellular modem Wi-Fi firmware Boot firmware Other proprietary firmware Hardware licensing Obsolescence slowdown Modifiability Security Certifications Other
Librem 5[1] 3: Cameras and the microphone, Wi-Fi and Bluetooth, and baseband processor. All three also shut off sensors (GPS, compass, accelerometer etc.).[2] The Wi-Fi+Bluetooth card,[3] and the Modem[4] are on M.2 slots. 2017 NXP arm64[2][5][6] On replaceable m.2 card. Proprietary firmware isolated from CPU with a USB bus (like a USB Wi-Fi dongle)[2] Originally, proprietary firmware isolated over USB, no downloadable/modifiable firmware;[7] subsequently, Purism paid Redpine Signals to create open-source Wi-Fi/Bluetooth firmware for the RedPine hardware.[8][9] proprietary DRAM init code loaded on separate CPU[2] for RYF cert compliance[10][11] none in /lib/firmware; some non-modifiable proprietary firmware in components.[8] schematics released under GPL 3.0+[8] User-replaceable (but custom-sized[8]) battery, lifetime updates[12] Display and frame fused. Phillips-head screws.[8] Wi-Fi and Bluetooth on replaceable m.2 cards (the former custom-made).[8] m.2 card slots. Purism has traditionally had more time-limited parts availability.[8] slot for an OpenPGP card, planned Librem key support[8] Tentatively recommended by Free Software Foundation (FSF).[13]

Operating system PureOS is endorsed by FSF.[14][15]

Seeking FSF "Respects Your Freedom" endorsement.[16][17]

Convergence; will run as desktop.[12] Headphone jack. Carrier-free OTT service available.[18]
PinePhone[19] 5: Modem & GNSS, Wi-Fi & Bluetooth, microphone, rear camera, front camera, audio jack[20] (DIP switches inside back cover[2]). No kill switch for other sensors.[8] 2015 Allwinner arm64 (Allwinner violates the GPL)[2] Quectel EG25-G. Ships with proprietary firmware isolated from CPU with a USB bus.[2][21] More secure, better-featured free replacement exists, but can't ship due to regulatory threats.[22] proprietary Wi-Fi/Bluetooth firmware,[21] in /lib/firmware.[8] Efforts to replace it are in beta, but may never be legal to ship, same as original PinePhone.[23] open-source boot software[2] proprietary schematics published[8] User-replaceable battery, 5-year production run. Phillips-head screws.[8] I2C pogo pins, back mods can be added. Cannot be upgraded beyond USB 2.0. Bootable from a microSD card. Good parts availability.[8] GPS and modem on same kill switch; neither can be used while the other is airgapped.[8] entire phone can be disassembled. Headphone jack. Convergence.[24][25]

Mobiles expected to be in production

Model Expected release date Hardware kill switches Modular smartphone System-on-a-chip (Soc) Baseband cellular modem Wi-Fi firmware Boot firmware Other proprietary firmware Hardware licensing Obsolescence slowdown Modifiability Security Certifications Other
DragonBox Pyra Mobile Edition Unclear, possibly defunct None The PCB is separated in three parts: CPU board (CPU, RAM and storage), mainboard (ports, Wi-Fi and Bluetooth) and the display board. schematics will be available to users[26][clarification needed]
Necunos NC 1 Unclear, possibly defunct None 2011 NXP i.MX 6 Quad and 4x Cortex-A9 MP, 32-bit[8] None[8] Proprietary blob for wi-fi driver (for regulatory reasons)[27] Blob without access to the main memory;[28] via SDIO[8] probably binary blobs on separate ROM, given cert aspirations[8] binary-blob proprietary firmware will not have memory access[8] strong focus; most sensors omitted for security. Seeking FSF endorsement.[28] 100 Mbit/s ethernet port[8]
Mudita Kompakt Q2 2025[needs update][29] Yes[30] MediaTek MT6761V/WBA (Helio A22)

2GHz quad-core ARM Cortex-A53 processor with Imagination GE8300 graphics[31]

Liberux NEXX July 2026[32] Cellular modem, camera, microphone Separate storage, RAM and cellular mdem Rockchip RK7588S Qualcomm Snapdragon X62 Publish own schematics. Aim to minimise undocumented components.

Mobiles no longer in production

Hexacore. 2016 Rockchip RK3399S and 2× A72 and 4× A53 CPU cores @ 1.5 GHz[23] Quectel EG25-G.[23] Ships with proprietary firmware for regulatory compliance[22] (isolated from CPU with a USB bus[2][21]). More secure, better-featured free replacement exists.[22] proprietary Wi-Fi/Bluetooth firmware,[21] in /lib/firmware.[8] Efforts to replace it are in beta, but may never be legal to ship, same as original PinePhone.[23] open-source boot software,[2] same as original PinePhone.[23] ? User-replaceable[35] Samsung J7 form-factor 3000mAh battery. Phillips-head screws.[23] I2C pogo pins, back mods can be added (all compatible with original PinePhone). USB 3.0. Bootable from a microSD card. Good parts availability.[8][23] GPS and modem on same kill switch; neither can be used while the other is airgapped.[23] entire phone can be disassembled. Headphone jack. Convergence (will run as a desktop if monitor and keyboard plugged in).[23]
