LineageOS is a free, open-source custom Android distribution built and maintained by a global community of volunteer contributors, per the project’s official website. The project hosts a public, regularly updated device compatibility list covering hardware from more than 20 global manufacturers, and delivers monthly security patches and built-in privacy controls for all supported devices.
New community device ports are added to the public list on a continuous, rolling basis as they are completed by project contributors, and customization options are a stated core pillar of the project alongside its regular security update cadence.
LineageOS Open-Source Android ROM Supports: What Is LineageOS?
LineageOS launched in December 2016 as the direct successor to the CyanogenMod project, which was discontinued by its parent company Cyanogen Inc. later that year. The project is governed by the LineageOS Team, a core group of volunteer maintainers who oversee code contributions, release testing, and compatibility certification for supported hardware from contributors across more than 30 countries. All LineageOS source code is publicly available under the Apache 2.0 license, allowing any developer to audit, modify, or redistribute the software without restriction. The project’s first stable release, LineageOS 14.1, launched in January 2017 based on Android 7.1 Nougat, and has since released 7 subsequent major stable versions based on newer Android releases. For example, the project’s public code repository hosts the full source code for every LineageOS release, with complete commit histories and code review logs accessible to all users for independent verification.
Which Global Manufacturers and Devices Are Supported?
The LineageOS project maintains a public, continuously updated device compatibility list on its official website that covers hardware from more than 20 global manufacturers as of the project’s mid-2026 update. New community-developed device ports are added to this list on a rolling basis as contributors complete stability testing, bug fixing, and code integration for unlisted hardware. Supported manufacturers include major global brands such as Samsung, OnePlus, Xiaomi, Google, and Sony, alongside smaller regional device makers serving markets across Asia, Europe, and North America. The project supports devices released as far back as 2016, extending the official software support lifecycle for many hardware models that no longer receive updates from their original manufacturers. Each entry on the public device list includes the specific device model number, supported LineageOS version, build status (official or community-maintained), and a list of known issues such as non-functional fingerprint sensors or missing camera features to help users assess compatibility before installation. The project does not support devices that are locked to specific carrier firmware or that have unrecoverable bootloader locks, as these hardware restrictions prevent users from installing custom system software.
How Frequently Does LineageOS Release Security Patches?
Every device listed on LineageOS’s public supported device list receives monthly security patches on a fixed recurring schedule, per the project’s official update policy. These patches are released on the first Monday of every month, aligned with Android’s monthly security bulletin releases, and include fixes for vulnerabilities disclosed by Google’s Android Security Team as well as upstream Linux kernel patches for hardware-specific security flaws. For example, LineageOS 21, which is based on Android 14, receives monthly security updates that patch critical vulnerabilities such as those affecting the Android media framework, system-level privilege escalation flaws, and Wi-Fi stack bugs that could allow unauthorized network access. The project publishes a public changelog for every monthly security patch, listing all included fixes and their corresponding CVE (Common Vulnerabilities and Exposures) identifiers for full transparency. Devices that are no longer listed as officially supported do not receive monthly security patches, though community maintainers may release periodic updates for older hardware on a case-by-case basis.
What Built-In Privacy Controls Does LineageOS Offer?
LineageOS includes built-in privacy enhancements that let users control system-level data sharing across their devices, a core feature of the distribution since its 2016 launch. Specific privacy tools include the Privacy Guard feature, which lets users grant or revoke app permissions for sensitive data such as location, contacts, microphone access, and SMS messages on a per-app basis. Privacy Guard was first introduced in LineageOS 14.1, the project’s first stable release, and has been updated with new granular permission controls in every subsequent major release. The distribution also includes a system-wide ad blocker that can be enabled without requiring third-party app installation, as well as a secure messaging feature that encrypts SMS and MMS messages end-to-end by default for supported devices. For example, users can configure Privacy Guard to block all apps from accessing their location data when the device is locked, a setting not available on most stock Android distributions. The project also includes a feature called “Heads Up Notifications” that lets users view sensitive notification content on the lock screen without unlocking the device, reducing the risk of accidental data exposure.
What Customization Options Does LineageOS Include?
Customization options are a stated core development priority for the LineageOS project, positioned alongside its regular security update cadence as a foundational pillar of the distribution. The project includes a built-in theme engine that lets users modify system-wide colors, icons, and fonts without requiring third-party apps or root access. Additional customization tools include the ability to adjust the status bar layout, change the navigation bar style, modify the lock screen clock and notification settings, and configure system-wide gesture controls for tasks such as launching apps or toggling quick settings. For example, users can set up a custom gesture that opens the camera app when they double-press the power button, a feature not available on most stock Android distributions. The project also includes support for custom icon packs, system font replacements, and status bar icon customization, giving users full control over the look and feel of their device’s user interface.
Is LineageOS Free to Download and Use?
LineageOS is completely free to download, install, and use, with no paid tiers, subscription fees, or in-app purchases required for core functionality. The project is funded entirely by community donations and voluntary contributions from users, with no advertising or user data collection for profit. The project does not accept paid advertising or sell user data to third parties, a policy that is explicitly stated in its official code of conduct and privacy policy. All official LineageOS builds are signed with the project’s public release key, and the distribution does not include any preinstalled bloatware or third-party apps that collect user data without explicit user consent. For context, the project’s official donation page accepts one-time and recurring contributions from users to cover server costs, development expenses, and hardware testing costs, with all financial records published publicly annually for full transparency. The project also does not require users to create an account or provide personal information to download official LineageOS builds, further reducing user data exposure.
How Can Users Confirm Their Device Is Compatible?
Users can confirm their device’s compatibility with LineageOS by checking the project’s public device compatibility list on its official website, which is updated in real time as new ports are completed. Each device entry on the list includes the specific model number, supported LineageOS version, build status (official or community-maintained), and a link to the official installation guide for that specific hardware variant. The project also maintains a public community forum where users can ask questions about device compatibility, installation troubleshooting, and post-installation configuration, with responses provided by experienced community contributors. For example, a user with a Samsung Galaxy S23 can search the device list for the model number SM-S911B to confirm official LineageOS 21 support and access the step-by-step installation guide for that specific variant, including instructions for unlocking the device’s bootloader and flashing the custom recovery. The project explicitly warns users that installing LineageOS will void the manufacturer’s warranty on most devices, and recommends that users back up all personal data to a separate storage location before beginning the installation process.
Bottom line: For Android users seeking a free, community-developed custom ROM with monthly security patches, granular system-level privacy controls, and support for devices from more than 20 global manufacturers, LineageOS offers a public, regularly updated device list to confirm device compatibility before installation. Users should verify their specific device model is listed as supported, back up all personal data, and note that installation will void most manufacturer warranties before proceeding with the setup process.
