Please bear in mind that this is beta software and, as such, maybe less stable than stable MP builds. If you are installing this build, is highly recommend to make a full system back-up before proceeding. It is also recommended you read all the instructions and notes before proceeding.

Enabling the AOD feature will lead to increased power consumption in the build. However, this will be optimized in the upcoming builds.
Please keep in mind that this is beta software. These builds are sometimes not as stable as official OTAs generally are. By installing this update, you accept the potential risks.
