[Root] Manually Clean Android System - Android Devices

Here are the list of folders that can be cleaned from android root. This will speed up your phone. This Clean-Up can be done to clear traces of uninstalled apps before doing any loot trick.

I use Xplore file manager. U can use any file manager with root access.

System folders:
Delete all the files inside these folders but don't delete folders.
/data/anr
/data/system/dropbox
/data/system/usagestats
/data/system/netstats
/data/system/procstats
/data/tombstones

Sdcard Folders to deleted
.DataStorage
.UTSystemConfig
Delete all files starting with "." in root of sdcard only
Also delete folder in
/sdcard/Android/data
Which are not related to any installed apps(leftovers).
Some phone may have two external storage clean it accordingly (use little brain).
