Free some internal storage memory and speed up your android device with this application.
Root is required!
It is highly recommended to make a nandroid backup before changing system files.
Jelly bean users: be sure to make a backup before using this application!!!!!!

Updated system applications decreases phone internal storage, because the update is stored in /data/app and the original apk is still in /system/app.
System app cleaner will automatically:
- backup the original apk in /sdcard/system cleaner/ (in case you want to restore the original apk)
- delete the obsolete apk
- integrate the update to the system
- delete dalvik-cache(optional but recommended)
- reboot device (optional but recommended)
By doing this, a considerable amount of internal memory storage will be freed.
How to use it:
- start the application
- let it check for updates
- start and let the application finish the work
- restart the device (preferable with deleting the dalvik-cache to free some more space if possible)
NOTE: the first restart will take longer time to rebuild the dalvik-cache(this is normal)
