#flag_tuner.sh
 
#~info~#
#busybox & su required
#
#custom overlays by oems like samsung, sony, lg & htc apply several
#(so it wont work on cm or aosp based roms because they dont include these settings)
#(actually... some report it works great, so go ahead and at least give it a try!)
#custom build settings to control how the ui and multitasking works
#by disabling most bad ones via the build.prop settings you can smoothen up
#overall transitional events on your device, in return "smoothening" up the ui.
