#android 15 upgrade

LineageOS, the renowned open-source Android distribution, has officially released LineageOS 22.1, bringing Android 15 (QPR1) to over 100 devices. This update allows users with older smartphones to experience the latest Android features, extending the lifespan of their devices beyond the manufacturer’s official support. The development team expedited the release of LineageOS 22.1 by building upon their previous adaptations of Google’s UI changes in earlier Android versions. However, they encountered challenges due to Android’s new trunk-based development model, which introduces significant codebase changes every three months. To align with Android’s updated release cycle, LineageOS has reinstated its dot versioning system. Consequently, the current release is named LineageOS 22.1, indicating its foundation on Android 15 QPR1. Future versions are expected to follow this naming convention, with releases such as LineageOS 22.2 based on Android 15 QPR2, and LineageOS 23.1 based on Android 16 QPR1. This release underscores LineageOS’s commitment to providing extended software support and new features to a wide range of devices, ensuring that users can continue to enjoy an up-to-date Android experience on their older smartphones.
