Just tested settings_d.apk on gingerdx v25/stock kernel. This is my report for now.
- pretty much everything.
-notification widget in status bar pull down works flawlessly (that includes brightness too)
-brightness inside settings (F.C.)
-volume inside settings (F.C.)
Hope this helps those gingerdx users who mite want to try it...here are some screenshots i've made:
switching back to the default settings app until the above bugs are fixed (brightness+volume inside settings).
