Updating your mobile device to Android Kitkat 4.4 is not recommended due to the new External SD Card Write Restriction imposed by Google, the developers of the Android Operating System. Applications, and users via an app, are stripped of the ability to write any kind of data on the external SD card, limiting write access to internal storage only. Google claims that KitKat "secures" the SD card. This securing likely breaks most apps trying to use it.

Some apps seem to be able to create folders and copy files to the card, but after a few hours all the changes disappear. ES File Explorer is also unable to do any file management function on SD card. Astro File Explorer will display a popup window saying "SDcard is readonly due to Google and Android design".

If the Android device is rooted (jail-broke) then the restriction can be bypassed. However, not all devices can be root exploited, and not all users wish to risk invalidating their warranty by doing so.
