OnePlus devices are one of the most popular devices on XDA Developer Forum because of the flexibility in customization. OnePlus 2 launched with Lollipop but support for the device, unfortunately, ended with Android 6.0.1 Marshmallow. Thankfully LineageOS has released the Official update of Android 8.1 Oreo for OnePlus 2, having a fairly stable build.
LineageOS 15.1 was announced in February 2018 for a few numbers of devices. The Custom ROM gives a huge amount of features on the top of Stock AOSP Android, and even the Lineage support offers a LineageSDK for developers to integrate their apps with LineageOS features. But what people really enjoy in LineageOS is Stability and community support for its users.
The new update of LineageOS 15.1 for the OnePlus 2 comes with the latest security patch and Android Oreo features.
