process. It also retained the old versioning format (for example, Android 7.1 is LineageOS 14.1). Prior to the official launch of LineageOS, many developers from
XDA had already developed unofficial versions of LineageOS from the source code. All the released builds are signed with LineageOS' private keys.
Builds were released on a weekly basis until 12 November 2018, when the release cycle for devices has changed: the latest LineageOS branch is built daily, with devices receiving a "nightly" OTA update, while devices on the older branch were moved to a weekly release cycle.
Starting on 5 June 2020, the latest LineageOS branch is also moved to a weekly release cycle, as the server couldn't build all available supported devices in just one day, with some devices receiving updates later on the next day.

(''r/lineageos'').
The XDA Developers forums have been used by members of the Lineage community since the software's inception. Many devices are left unsupported by official releases so community members develop their own unofficial ROMs allowing older phones to use Lineage. These unofficial releases are often bundled with software intended to aid the user's experience that would otherwise be unseen in an official release. They also come with known bugs and security issues that may not be seen in official releases.
During August 2017 the LineageOS team held a Summer Survey in which they asked users for feedback to improve the development of the operating system. The results were published in October and, according to the team, they used the gathered data to improve the upcoming LineageOS 15 release. A second Summer Survey was conducted in August 2018.
As a response to one of the main suggestions received during their first public survey, LineageOS launched a section on their blog titled "LineageOS Engineering Blog" where Lineage maintainers and developers can contribute articles discussing advanced technical information pertaining to Android development.
LineageOS is also known for posting a "regularly irregular review" on its blog in which the active development of the work is discussed.

Although they are not included in LineageOS as such due to legal issues, users can flash the normal Google apps, including the Google Play Store and Play Apps, with a
Zip package, usually referred to as ''gapps'', while installing LineageOS. A side effect of using LineageOS and other custom roms is the impact on SafetyNet API. App developers can choose to enable a toggle in the app developer console to hide their app on the Play Store if a device doesn't pass SafetyNet tests, or can choose to check the SafetyNet status of a device to disable certain functionality. Notable examples would be Netflix, which is hidden on the Play Store, and Google Pay, which checks SafetyNet each time the app is used. Devices running LineageOS may have a smaller selection of usable apps in the Play Store as a result of these checks. LineageOS can be made to work with apps such as Netflix and Google Pay by installing Magisk and certain modules designed to hide the bootloader status.
Customization features
LineageOS offers several features that

(AOSP) does not include. Some of these features are:
* Button customization – Set custom location for buttons on the navigation bar, or enable on-screen buttons for devices with hardware buttons.
* Custom Quick-Setting tiles – Quick Setting Tiles such as "Caffeine" preventing the device from sleeping, enabling/disabling Heads Up notifications, "Ambient Display" and "ADB over network" are present to easily toggle frequently accessed settings.
* LiveDisplay – Adjust color temperature for the time of day.
* Lock screen customization – The lock screen allows all sorts of customizations, including media cover art, a music visualizer, and double-tap to sleep.
* Styles – Set a global dark or light theme mode and customize accent colors. This functionality can also be managed automatically by the system based on wallpaper or time of day (in line with LiveDisplay).
* System Profiles – Enable or disable common settings based on the selected profile (For example, a "Home" profile and a "Work" profile). The profile can be selected either manually or through the use of a "trigger", such as upon connecting to a specific WiFi access point, connecting to a Bluetooth device, or tapping an

* Custom pattern sizes – In addition to Android's 3x3 pattern size, a 4x4, 5x5 or 6x6 size can be used.
Security & privacy features
* PIN scramble – For users securing their device with a

, the layout can be scrambled each time the device locks to make it difficult for people to figure out your lock by looking over your shoulder.
* Privacy guard – Allow the user to fine-tune what permissions are granted to each application. For some permissions, it's possible to set a manual approval each time the permission is requested. It's also possible to find out how often apps use a specific permission. This feature was removed in the 17.1 branch in favor of an equivalent "permission controller" based on a hidden AOSP feature.
* Protected Apps – Hide specific apps behind a secure lock. This works hand-in-hand with Trebuchet; the app's icon is removed from the launcher, and "secure folders" can be created to easily access these applications. A pattern is used to lock these apps.
* Some "sensitive numbers", such as abuse support numbers, are not included in the call log for privacy. The phone application also includes a list of helpline numbers for the users to be able to easily reach them.
* Trust - helps to keep the device secure and protects privacy.
Developers & power user features

*Lineage Recovery - an AOSP-based recovery.
* (Optional) Root – Permit apps to function with

to perform advanced tasks. This requires flashing from Recovery either LineageOS's root add-on (supported until version 16.0) or a third-party implementation such as Magisk or SuperSU.
* Telephone call recorder, not available in all countries, due to legal restrictions.
* Weather providers – Display the weather in widgets or apps using a weather provider. This functionality is not included by default; a weather provider must be downloaded from the LineageOS Downloads website. App developers can create both providers and consumers of weather data.
Trust interface
As LineageOS evolved through development, the Trust interface was introduced for all the LineageOS 15.1 builds released since 12 June 2018. The interface can be found on supported devices under Security and Privacy tab under the Settings option, and enables the user to "get an overview of the status of core security features and explanations on how to act to make sure the device is secure and the data is private".
Additionally, while carrying out any action on the device, the trust icon is displayed, notifying the user that the action is safe.
Supported devices
![POCO X3 Pro running LineageOS 18](https://upload.wikimedia.org/wikipedia/commons/5/54/POCO_X3_Pro_running_LineageOS_18.jpg)
The number of devices supported by LineageOS has increased over time, with 157 for 17.1 and 18.1 .
Official builds on currently supported development branches are labeled as "nightly". For the first two months of the project, parallel experimental builds were also produced, allowing in-place upgrades from previous CyanogenMod installations and easing migration to LineageOS.
In 2019, LineageOS development builds were available for 109 phone models
with over 2.8 million active installs. As of 26 April 2022, 41 devices are receiving official 19 builds and 136 devices are receiving official 18.1 builds.

prank included with some April 2018 builds.
During the first week of April 2018 LineageOS released new builds with the "LOSGenuine" prank that informed unaware users of the software possibly being counterfeit via a persistent notification (which could not be disabled unless the user ran the following command in a root shell):
setprop persist.lineage.nofool true
When the notification was tapped, the software claimed that the device was "uncertified" and needed to mine "LOSCoins", which were a virtual currency and could not actually be spent. Affected builds also had a preinstalled "Wallet" app that showed the current balance of LOSCoins.
Many users mistook the prank for actual
malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, depri ...
, and others reportedly found it to be in "poor taste". It was especially criticized for being too "late" for an April Fool's joke, since many users didn't receive the update until days later, making the jest less obvious. On 10 April 2018, LineageOS team director ''ciwrl'' issued an official apology for the deceptive prank.
