Hello i find this thread http://forum.xda-developers.com/goog...tings-t2942838
where is possible to enable ambient display option. I successfully completed the procedure, but i can't recompile the systemui.apk, apktool said to me lots of error. I share with you my work for now, if someone can recompile systemui.apk.
The framework-res should be ok.
This for latest build from kevinjoa's cm12.
So i share with you the package with patched framework-res, apktool, etc...
