By Amos Batto (2026-10-05) - Five years ago, Linux phones appeared to be on the verge of becoming a viable alternative to the Android/iOS duopoly in the mobile phone industry. However, following the initial releases of the Purism Librem 5 and the PINE64 PinePhone in 2020, the Linux phone market has largely stagnated. This stagnation can be attributed to issues faced by Purism and PINE64, as well as limitations in the available Linux System-on-Chips (SoCs) that were inadequate for modern smartphone requirements, compounded by a lack of suitable hardware alternatives with effective free/open source drivers. Additionally, the mobile interfaces Plasma Mobile and Phosh were still developing, and there were no optimal distribution options for running these interfaces on Android kernels with standard integrated mobile SoCs. The underwhelming performance of the PinePhone and Librem 5, along with refund issues related to the PinePhone Pro and Librem 5, diminished consumer enthusiasm for Linux phones.
Recent developments suggest that conditions may be improving, potentially allowing Linux to emerge as a viable alternative to Android and iOS in the mobile sector, akin to how desktop Linux has gained traction against Windows and Mac OSX over the past thirty years. While it is unlikely that mobile Linux will significantly disrupt Google or Apple's business, there is potential for a niche market for Linux phones, similar to the availability of Linux PCs from various smaller companies, including TUXEDO, System76, and Purism.
There is a possibility that major phone manufacturers may eventually offer models with mobile Linux, similar to how Lenovo and Dell provide some PC models with Linux preinstalled. Motorola has announced plans to sell high-end phone models with GrapheneOS in 2027, indicating that Google may permit major manufacturers to offer alternatives, possibly in response to antitrust concerns. As the mobile industry increasingly restricts the ability to unlock Android phone bootloaders, consumer interest in alternatives to AOSP derivatives may grow, positioning mobile Linux as a potential solution.
Five years ago, the release of the Purism Librem 5 and PINE64 PinePhone generated significant attention, with tech reviewers like Linus Tech Tips testing them. A video by Mrwhosetheboss titled "Are Linux Smartphones about to KILL Android?" garnered 7.8 million views on YouTube. The Librem 5 was ported to Mobian and postmarketOS, while the PinePhone supported 20 different Linux distributions. Additionally, there was an increasing number of phone models capable of running Jolla's Sailfish OS and Ubuntu Touch on Android kernels, and many users were experimenting with postmarketOS on older devices. The development of Plasma Mobile and Phosh was progressing, and KDE and GNOME were adapting their applications for both desktop and mobile interfaces. The Waydroid project enabled the running of Android apps within a Linux container, contributing to optimism for mobile Linux. However, this anticipated future did not materialize, warranting an examination of the factors that hindered mobile Linux's progress.
Over the past 25 years, there has been extensive experimentation with various mobile operating systems based on the Linux kernel, beginning with devices like the Sharp Zaurus and Motorola A760. I have identified 29 different commercial mobile Linux variants that have existed, with many others likely unaccounted for. Numerous attempts have been made to establish mobile Linux as a significant player, including platforms such as EZX, MotoMagx, Maemo, LiMo, Moblin, Meego, Tizen, Firefox OS, webOS, Ubuntu Touch, and Sailfish OS. Motorola's exploration of different Linux varieties demonstrated that Google’s Android was not unique in its approach, yet it ultimately became the dominant mobile Linux flavor.
Despite being less visible today, mobile Linux operating systems continue to exist. The Jolla Group, which developed the MeeGo code for the Nokia N9, is still selling phones with Sailfish OS. Firefox OS, abandoned by Mozilla in 2016, was rebranded as KaiOS for low-end phones, although this market is diminishing as Android penetrates even the most affordable segments. Ubuntu Touch, which Canonical ceased supporting in 2017, is now maintained by volunteers at UBports. Both webOS and Tizen persist, though not as mobile operating systems; webOS is used in LG TVs, while Tizen is found in Samsung TVs.
A small Linux phone market continues to exist, albeit at a lower volume than during the 2020-2022 period when PINE64 launched the PinePhone and PinePhone Pro. However, the number of companies selling Linux phones has increased compared to five years ago, suggesting that many past challenges could be addressed moving forward.
Historically, hardware limitations have hindered the viability of Linux phones. SoCs that support Linux are typically found in single-board computers, TV set-top boxes, IoT devices, and embedded systems, which tend to have lower performance and energy efficiency compared to mobile SoCs designed for smartphones. These older SoCs are often produced on outdated process nodes, but they offer long-term support due to their use in applications with extended product life cycles, such as automobiles. In contrast, mobile SoCs supporting Android are more powerful but have shorter production runs.
For Linux phone designers to utilize a Linux kernel instead of an Android kernel, their options often involve limited processing power and energy efficiency. To avoid proprietary components, they may need to select older SoCs with established free/open source drivers or spend years developing support for newer SoCs, as Purism did with the NXP i.MX 8M Quad in the Librem 5. If they opt not to contribute their patches to the mainline Linux kernel, ongoing support for their hardware may become problematic with each new kernel release. Purism has chosen to upstream its changes, while the PinePhone kernel development has largely been handled by volunteers.
Chipmakers such as NXP, Rockchip, Allwinner, Amlogic, and Broadcom, which produce Linux-compatible SoCs, often lack the revenue to justify using cutting-edge process nodes. Although they can sell a Linux SoC for a decade or more, the sales volume is insufficient to recover the substantial costs associated with advanced process nodes. For example, manufacturing a wafer at TSMC's 3nm node costs approximately $19,500, compared to $3,000 at a 28nm node. Most Linux SoCs are low-cost chips with thin margins, requiring high sales volumes to generate profit. Some manufacturers, like NXP, focus on niche markets with higher margins, but their sales volumes remain limited.
To reduce costs, chipmakers frequently use older Cortex cores with lower licensing fees from ARM and opt for low-power Cortex-A5 series cores instead of higher-performance Cortex-A7 and Cortex-X series cores. NXP's i.MX 9 series processors exemplify this cost-cutting approach, with the i.MX 95 featuring six Cortex-A55 cores instead of a more efficient combination of Cortex-A78 and Cortex-A55 cores. The i.MX 95 was produced on a 16nm FinFET node, which is a slight regression compared to the 14nm node used in the previous i.MX 8M Plus processor. Broadcom has similarly utilized older Cortex cores and larger process nodes in its BCM series, despite the anticipated high sales volumes.
In contrast, the smartphone market, which sold 1.25 billion units in 2025, offers substantial volumes, allowing manufacturers to invest significantly in designing mobile SoCs for advanced process nodes. Integrated mobile SoCs, such as Qualcomm's Snapdragon and MediaTek's Dimensity, can be profitable due to their high sales volumes, despite being produced for shorter periods. Flagship models typically lose most of their market share after the first year, necessitating higher prices to cover the costs of cutting-edge technology.
