[split] 4.2.1 Not smooth. Downgrading to 4.1.2

[mke2fs]

There is now new information coming in that many Chinese are also experiencing the same issues of lack of smoothness. Perhaps their attention to detail is better than I thought.

Their solution is to put a custom launcher for the time being. It HELPS, but certainly doesn't solve the issue.

I am using ADW Launcher Ex at the moment. But still, I experienced lagging sometimes.
