Disabling "Storage space running out" notification in Status Bar? Is there any way to disable the "Storage space running out" notification on Cyanogenmod 10.1.3 [Android 4.2.2], through ADB or otherwise ?
To permanently disable storage notifications, try long-pressing on the notification, go to App Info and uncheck Show notifications. You must do it through long-pressing.

If it is un-checkable, hit Force Stop and confirm.
