Clear cache LG K40 / K30 – wipe cache partition & app cache

As we keep on using apps on our LG K30 & K40, the app cache keeps on accumulating. This can eat up your precious internal storage space. We should keep clearing the cached data from time to time. This can aid in speeding up the phone and also save you from the “storage space running out” error.

In the earlier versions of android, the recovery mode had an option to wipe the cache partition. It’s removed since Android Nougat 7.0. Now we have to clear the cached data via Settings.


How to Clear Cache on LG K40 & K30

We can clear the cache memory of an individual app or all apps at once. Let’s see how to do this on K30 & K40.

We are now on the “Internal Storage” screen.

Select the first option i.e. “Free up space”.

It gives various options to free up space. The 3 options are –

Temporary files, Download folder & Idle apps.

The cached data is stored in the temporary files folder. The downloaded files are stored in the download folder. The idle apps are those apps which are unused for a long time.

Tap “Temporary files” to clear the cached data.
