Chances are, if you're picking up an 8GB Nexus 4, or even a 16GB Nexus 7 (or are stuck with an 8GB N7), at some point you might run low on storage. It happens to the best of us.
Fortunately, in Android 4.2, Google's given you a new way to free up some space with just two taps. Instead of having to trudge through your entire list of installed apps one by one, you can now clear all cached app data straight from the storage menu.
Just head to settings, then to storage, and tap on the new "Cached data" section in the list.
