Custom ROM is a custom operating system that is usually built based on Android for users to change the default operating system on their respective devices and explore the features and functions of Android in more depth. The last time I "played" with this custom ROM was in 2021 with the Xiaomi Mi 11. Although its use is not as great as it was 10 years ago, its development is still active to this day. The latest LineageOS 21 has been launched based on Android 14.
In this new version, Lineage has updated their system applications such as Jelly web browser, Dialer, Contacts, Messaging, LatinIME (Keyboard), and Calculator to the Material You design. At the same time, a new photo album application called Glimpse was also introduced. For Android TV, LineageOS 21 brings an ad-free launcher to users. Those looking to install and receive updates, LineageOS 21 also uses A/B builds to make it easier for users and developers.
With Custom ROM, in addition to being able to try interesting features and functions that device manufacturers usually hide - devices that manufacturers stop supporting updates can still receive a new lease of life with the latest operating system and security. Those interested can visit the LineageOS website.
