Comparison of open-source mobile phones
From Wikipedia, the free encyclopedia
The scope for this page is that used for list of open-source mobile phones.
| 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,[citation needed] 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. |
