Smooth Scroll, 30-step Volume, and On-Screen Controls for CM10 on Galaxy Ace
A couple of months back, we wrote about the Samsung Galaxy Ace S5830 getting an unofficial port of Android 4.1 Jelly Bean based CyanogenMod 10. Meanwhile, the Jellaxy project has also brought another unofficial CM10 port to the device. While CM10 may seem to be “just right” for many of us, there is always room for improvement. XDA Senior Member King ACE has filled in some of that room by developing a mod that adds several features to CM10 running for the Ace.
The features include smooth scrolling, center clock on lock screen and status bar, 30-step volume control and ICS-style on-screen controls. The mod is built for the Jellaxy ROM for the Ace but should work on other CM10 ports available for it as well. Note that it will not work on other CM10-based ROMs such as MIUI that have a modified framework.
Before installing the mod, it is recommended that you backup your existing SystemUI.apk from /system/app and framework-res.apk from /system/framework, in case you wish to revert the changes. You can find more information in the original thread.
