Folks,

Credit to AndroidON for this mod. Outlined in his thread: [HOWTO] More smooth scroll & volume step increase for MOST android phones.

Some android applications have a lag (or stutter) when they scroll. The 'scrollingcache' function inside android is causing the issue. Some application developers recommend disable 'scrollingcache' in app's internal config, but not all applications have disabled scrollingcache. The mod will disable the scrollingcache throughout the Android OS. All apps will have no problem with the mod. Scrolling should be smoother all around.

The details are described in the AndroidON's thread.

AndroidON's original mod also includes a volume increment change for music from 15 to 30 steps. Unfortunately the volume increment mod does not work correctly on our phones, so it cannot be included.

UPDATE... I've modded the "framework.jar" from several ROM's:

UCKH7 stock deodexed and rooted by PAulyhoffman

UCKK6 Stock deodexed and rooted

UnNamed v1.3.2 and v2.2.1 by gtg465x

MIUI 1.12.30 and 2.1.13 by shep211

Serendipity 8.2 by MikeyMike01

CM7 7.2.0-RC0 (GWK74-11162011) posted by atinm

SensatioN 3.0 by Crysis21

SHOstock v1.7(+) by Showman94 has the Smooth Scroll mod included. Visit his thread!

ICScrewD v1.6.0(+) by jivy26 has the Smooth Scroll mod included. Visit his thread!

The CWM script clears cache and dalvik. Be patient upon reboot. It will take a bit to rebuild cache and dalvik.

Each ROM has two files: (1) Smooth Scroll (2) Revert
