Halogen OS is a third party ROM for the Honor 8 android phone. It is based on AOSP and Code Aura forum project. The motive of the Halogen OS is to bring latest android features and provide a stable ROM to the end users. Keep in mind that this ROM is designed for daily use and not for tinkering around. So if you are planning to install custom Honor 8 kernels onto it, do not use this ROM as it does not supports overclocking.
Here are list of its features:
Substratum Theming Support
Custom Lockscreen Visualizer
SuperUser Capable
Dexpreopt Enabled

Support for 3rd Party Webviews
Support for Modern Service
Long Press Home for Assistant
