This is a list of mobile phones with open-source operating systems.
Scope of the list[]

Cellular modem and other firmware[]

Some hardware components used in phones require drivers (or firmware) to run. For many components, only proprietary drivers are available[1] (open source phones usually seek components with open drivers.[citation needed]) If firmware is not updatable and does not have control over any other part of the phone, it might be considered equivalent to part of the hardware. However, these conditions do not hold for cellular modems.[1]
As of 2019, all available mobile phones have a proprietary baseband chip (GSM module, cellular modem),[2][3][4] except for the Necuno, which has no such chip and communicates by peer-to-peer VOIP.[5][6] The modem is usually integrated with the system-on-a-chip and the memory.[4] This presents security concerns; baseband attacks can read and alter data on the phone remotely.
The Librem 5 mobile segregates the modem from the system and memory, making it a separate module, a configuration rare in modern cellphones.[3][4] There is an open-source baseband project, OsmocomBB. There is a project based on illicit leaked source code for the Calypso modem called .
Operating system: middleware and user interface[]

Generally, the phones included on this list contain copyleft software other than the Linux kernel, and minimal closed-source component drivers (see section above).
- Android-based devices do not appear on this list because of the heavy use of proprietary components, particularly drivers and applications.[7][1][8]
- There are numerous versions of Android which seek to replace the proprietary components, such as LineageOS (successor to the now-defunct[9][10] Cyanogenmod) and Replicant, that can be installed on a large number of phones after-market. Phones natively running these are included.
- WebOS was initially available only under a proprietary license but the source code was later released under a free permissive license by HP. Open WebOS will not run on all WebOS devices.
- Firefox OS was released under a permissive MIT license but its KaiOS successor is proprietary; the former is included.
- Maemo (mixed permissive and proprietary licenses) spawned Maemo Leste (permissive and protective)[citation needed] and MeeGo (permissive); MeeGo split into Tizen (proprietary) and Mer middleware (see diagram).[citation needed] All but Tizen are included.
- Sailfish OS is a proprietary user interface atop the Mer middleware; it is thus not included.
- Qt Extended had proprietary components and is not included, but its community fork QTMoko/OpenMoko is.[clarification needed]
Note that it is often possible to install a wide variety of open-source operating systems on any open-source phone; the higher-level software is designed to be largely interchangeable and independent of the hardware.[11]

Distributions for existing phones[]
![](http://upload.wikimedia.org/wikipedia/commons/thumb/9/94/Plasma-mobile-hammerhead_01.jpg/220px-Plasma-mobile-hammerhead_01.jpg)
postmarketOS, Ubports, and KDE Neon are open-source distributions running on existing smartphones originally running Android. Maemo Leste is available for Nokia N900 and Motorola Droid 4.
There exists a database listing which older phones will run which open-source operating systems.[33][34]
Custom-made phones[]
It is possible to home-build a phone from partially open hardware and software.[35][36] The Arduinophone[36] (touchscreen) and the MIT DIY Cellphone (segmented display)[37][38] both use the Arduino open-hardware single-board computer, with added components. Circuitmess Ringo (previously MakerPhone) is another DIY Arduino phone with open source firmware[39] and available schematics,[40] focusing on education. The PiPhone[41] and ZeroPhone[42] are similar, but based on the Raspberry Pi.
The main components to make an open mobile phone are:
- Back cover
- Touch screen
- Battery
- Logic board

The cellular modem is arguably the most complex part of a mobile phone. The modem is the component that has to implement all the familiar protocols you would associate with a phone (like 2G, 3G, 4G and the upcoming 5G). It does so by running its own proprietary black box operating system. The cellular modem is also covered by thousands of patents held by hundreds of patent owners. Now imagine this… This cellular modem sits right on the same RAM bus as the SoC! Non-free software not only has access to the data flowing to and from the SoC, but also has the ability to modify it. Because this modem operating system is a propreitary black box, we have no idea what this component does or what kind of vulnerabilities it has... The situation is further complicated by the fact that during our research into cellular modems, we realized that there are only a handful of silicon vendors in the world that make these chipsets and nearly all of them integrate their model with the SoC on the same bus. In addition, you historically need to acquire a license to run the proprietary firmware to power the modem on SoCs.. This left us with only one choice: to use ready-made modem “modules” and our own layout that isolates the modem from the SoC. There are a number of these modem modules available in different form factors with various available options in speed, bands, etc. By going the module route we can both provide supplier choice in modems that meet our strict standards, and also allow modem isolation from the RAM and host CPU.(text is CC-by-SA 4.0)

As for software, the phone arrives preloaded with a factory test image rather than an end-user operating system. This preloaded factory test suite is running on Linux – postmarketOS to be precise – which allows you to test various features of the phone and run an automated test. ... I assume that everyone getting a Braveheart PinePhone understand that it’s up to them to find the operating system build they are interested in, flash it and take part in the community discussion and ongoing development.
