Comparison of open-source mobile phones

The scope for this page is that used for List of open-source mobile phones.

Mobiles that currently are or are expected to be in production
Model Hardware kill switches System-on-a-chip (Soc) Baseband cellular modem Wi-fi firmware Boot firmware Other proprietary firmware Hardware licensing Obsolescence Modifiability Security Certifications Other
DragonBox Pyra Mobile Edition schematics will be available to users[1]
Librem 5 3: Cameras and the microphone, Wi-Fi and Bluetooth, and baseband processor. All three also shut off sensors (GPS, compass, accelerometer etc.).[2] 2017 NXP arm64[2][3][4] 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;[5] subsequently, Purism paid Redpine Signals to create open-source Wi-fi/Bluetooth firmware for the RedPine hardware.[6][7] proprietary DRAM init code loaded on separate CPU[2] for RYF cert compliance[8][9] none in /lib/firmware; some non-modifiable proprietary firmware in components.[6] schematics released under GPL 3.0+[6] User-replaceable (but custom-sized[6]) battery, lifetime updates[10] Display and frame fused. Phillips-head screws.[6] Wi-fi and Bluetooth on replaceable m.2 cards (the former custom-made).[6] m.2 card slots. Purism has traditionally had more time-limited parts availability.[6] slot for an OpenPGP card, planned Librem key support[6] Tentatively recommended by Free Software Foundation (FSF).[11]

Operating system PureOS is endorsed by FSF.[12][13]

Seeking FSF "Respects Your Freedom" endorsement.[14][15]

 Convergence; will run as desktop.[10] Headphone jack. Carrier-free OTT service available.[16]
PinePhone 5: Modem & GNSS, WiFi & Bluetooth, microphone, rear camera, front camera, audio jack[17] (DIP switches inside back cover[2]). No kill switch for other sensors.[6] 2015 Allwinner arm64 (Allwinner violates the GPL)[2] Quectel EG25-G. Proprietary firmware isolated from CPU with a USB bus[2][18] proprietary WiFi/Bluetooth firmware[18] in /lib/firmware[6] open-source boot software[2] proprietary schematics published[6] User-replaceable battery, 5-year production run. Phillips-head screws.[6] I2C pogo pins, back mods can be added. Cannot be upgraded beyond USB 2.0. Bootable from a microSD card. Good parts availability.[6] GPS and modem on same kill switch; neither can be used while the other is airgapped.[6] proprietary code in /lib/firmware currently makes the mobile ineligible for RYF cert.[6] entire phone can be disassembled. Headphone jack. Convergence.[19][20]
Necunos NC 1 None None strong focus; most sensors omitted for security. Seeking FSF endorsement.[21] Ethernet port
Meizu PRO 5 Ubuntu Edition None
Meizu MX4 Ubuntu Edition None
