Lineage OS

LineageOS is an Android-based operating system with a sizable free and open-source software component for mobile devices, tablet computers, and set-top boxes. It is the successor of CyanogenMod, which was cloned in December 2016 when Cyanogen Inc. said it would no longer be developing the project and shut down the infrastructure sustaining it. Because Cyanogen Inc. still had the rights to the term Cyanogen, the team changed the fork's name to LineageOS.

On December 24, LineageOS's source code was formally published and is available on GitHub and GitLab. Oneplus is one of the most popular phones, with one million customers, according to sources from March 2017.

The competition LineageOS is well-known in the field of specialized Android development. It was created to take the role of CyanogenMod and currently supports a wide range of devices, allowing enthusiasts to optimize and customize their systems without being restricted by heavy skins. A big update based on Android 13 was revealed by the LineageOS team as LineageOS 20.

Features of LineageOS 20:

There are various features in lineageOS 20. Some of them are as follows:

• The security updates for LineageOS 17.1 through 20 cover the period from April 2022 to December 2022.
• Now, LineageOS has a brand-new photography program called Aperture. It is based on Google's incredible CameraX library and delivers a much more "to stock" camera app experience on many devices. Exceptional credit goes to the authors of this, SebaUbuntu , LuK1337, and luca020400, and to designer Vazguard and the whole team for their work in integrating it into LineageOS and adapting it for our large range of supported devices.
• The most recent version of WebView is Chromium 108.0.5359.79.
• In Android 13, the volume panel was completely rebuilt, and the side pop-out expansion panel was improved.
• It completely supports Linux 5.10 builds with complete out-of-tree module support to comply with current AOSP standards.
• Numerous repairs and enhancements have been made to the AOSP Gallery app via the Lineage branch.
• Numerous bug fixes and enhancements have been made to the Updater app, along with a stylish new Android TV look.
• Back upstream, the Seed Vault backup app has more alterations and enhancements.
• The Recorder app has been modified so that it can take advantage of Android's built-in capabilities while still offering the LineageOS features you've come to expect.

1. Much of the app's architecture was changed.

2. It has been added material that you support.

3. There have been several threading fixes, and the high-quality recorder (WAV format) now supports stereo.

• Unlike Google's ad-enabled launcher, Android TV releases now include an ad-free Android TV launcher that also supports Google TV-style builds. Moving forward, they are considering switching to this launcher on compatible devices.
• Many Google TV features (like the Two-Panel Settings app, which has a much more pleasing appearance) have been transferred to LineageOS Android TV releases.
• More third-party root systems may be used because the adb_root service is no longer dependent on the build type property.
• The merging procedure for Android Security Bulletins has been substantially simplified due to the extensive rewrite of merge scripts. Supporting devices with complete source releases, such as Pixel smart phones, have also benefited from this improvement.
• LLVM has been completely adopted and built by default, using the LLVM integrated assembler and the LLVM bin-utils.
• For Android 13, Setup Wizard has been updated with a new style and a more fluid user interface.

Lineage OS 20, a new default camera app:

• You could have been dissatisfied if you've ever used LineageOS default camera app. The software, named Snap, was a hack of Qualcomm's own camera app, and later they switched to using Camera2, the standard AOSP camera app. Although it's a simple program, it does the job, but most people won't find it useful due to the significance of Aperture.
• Aperture makes use of the CameraX API, which has recently advanced to the point that a whole camera app may utilize it. It enables Aperture to use the following functions:
• Support for auxiliary cameras (device administrators must allow it):

1. Controls for video frame rates.

2. Complete control over the parameters for electronic and optical image stabilization.

3. A leveling tool to measure the angle of the device orientation.

For those who are unaware, Google's CameraX library promises to make the creation of camera apps for Android simpler. On the surface, it encases Camera2, an API that enables apps to examine a device's camera capabilities under the condition that the OEM exposes such capabilities to the API. Device makers have the option of including CameraX-compliant extension libraries with their phones, which enable third-party developers to easily use native camera functions to lessen the fragmentation of camera features.
