By default, phhusson's generic AOSP Treble ROM is bare bones. That means it does not include features such as Night Light, Ambient Display, or Adaptive Brightness. Luckily all you need is the right overlay and you can bring these features back.
I tested this on the Huawei Mate 10 Pro and everything seems to work save for the lift-to-wake gesture. I am not sure if a simple overlay can enable that, as I already target the right boolean value for it. As for Adaptive Brightness, the lux and corresponding backlight values were borrowed from the Huawei Mate 9's framework-res.
With the release of phhusson's Android 8.1 Oreo Treble GSI, I thought I would take the time to update my overlay as well with a new feature: Always on Display. You can download the overlay from the attachment in this comment, and install it using the same set of instructions below (don't install the overlay attached in this post if you want AOD). Please read the warnings carefully. I accept no responsibility for anything you do with your phone.
I have updated the attached framework overlay to include the following features:
- WiFi automatic wakeup
- Pinner service for the default camera app and critical framework files
This should work on any device that can boot phhusson's Treble ROM.
- Download the attached overlay
- With root, push the overlay to /vendor/overlay. Create the folder if it doesn't exist.
- Run the following command in a rooted terminal or ADB shell: Code:
chcon u:object_r:vendor_overlay_file:s0 /vendor/overlay;chcon u:object_r:vendor_overlay_file:s0 /vendor/overlay/framework-res__auto_generated_rro.apk
XDA Labs adds emojis in the command for some reason. Open this thread in a browser to get the right command.
Why do you need to run that command? Without it, the overlay won't be seen as installed and isn't enabled. I'm not sure why, but according to phhusson it's an SELinux-related issue and this command fixes that.
