Works great for me...
My Device: Samsung Galaxy Ace (S5830)
Android 4.2.2: Cyanogenmod 10.1
The Device starts 2-3 seconds faster... And the Interfaces (Touchscreen + Keys) respons faster after turning on, not so...
Go to -> Settings -> Developer Settings -> Developer Tools -> Media Provider -> Scan SD card...
You don't need any app to trigger media scanner.
I want to know what are the best Max CPU, Min CPU and best gov for my samsung galaxy ace cm 10.2
It depends on what you want to have: power full or battery save...
if the flash process is finished,
its your choice... power and home or battery remove.
