LG K30 LM-X410

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.

LG K40 / K30 Wipe Cache Partition

On your LG K30 / K40 open “Settings” as shown above.

Choose the “General” tab and select “Storage”.

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.

On the “Temporary files” page we have 2 options –

Cached data & Clip Tray temporary files. I’m deleting only “Cached data”.

Tap “DELETE” at the bottom-right to wipe the cache partition.

You can see the cached data is cleared. Its current size is zero bytes.

 

LG K40 & K30 Smart Cleaning

There is one more method to clear the cached data on LG K30 & K40.

We can use the Smart Cleaning tool to do the same.

Open Settings > General > Smart Cleaning.

 

Smart Cleaning can free up space by deleting unnecessary files and stop unused apps to free up the RAM.

Tap “Optimize phone” to initiate the process. Wait for a while.

Now it says “Optimized”. We have cleared the cached data.

 

LG K30 & K40 Clear App Cache

We can also clear the cache of individual apps –

Once again Open Settings > General > Apps & notifications.

Select the first option “App info”.

Choose the app whose cache data you wish to clear.

Let’s open the “Amazon Assistant” app.

Hit “Storage” & then “Clear cache” to do the needful.

The cached data of the Amazon Assistant app is now cleared. The current cache size is 0 bytes.

On LG K40 we can split the screen into 2 and work on multiple apps at once. This multitasking feature is termed a multi-window on K40. Few of the system apps do not work in the split-screen mode.

Camera, Settings, LG smart world, Audio Recorder, Music, FM radio, Game Launcher, and LG mobile switch are few apps which do not work in the Split Screen Mode.

Let’s see how to split the LG K40 screen with the help of the video & screenshots as follows –

How to do Split Screen on LG K40

To use Split Screen / Multi-Window Mode, tap the Overview / Recent Apps button.

Look for the Split Screen icon on the running app.

The app which supports split-screen mode has the multi-window icon as marked in the above screenshot.

Let’s launch the Photos app in the multi-window mode. It will occupy the upper half of the screen.

Now to choose the second app for the lower half, tap the home button.

Choose the app which you wish to use in the lower portion.

Now you can see the photos app is running in the upper half and messaging in the lower portion.

LG K30 / K40 Disable Split Screen

Swipe the screen all the way towards the top or bottom to close multi-window mode.

If pulled in the downward direction the app in the upper half will occupy the whole screen and vice versa.

I’ve made a video on the same. You can watch it below –

LG K40 Split Screen – Gesture and Buttons Mode

If your Home Touch Button Style is “Gesture and Buttons”, follow the below steps to use the “Split-Screen” mode –

Open Settings > Display > Home touch buttons on your K30/K40.

 

Choose the Home Touch Button style as “Gesture and buttons”.

In this mode, there is no overview / recent apps button.

We have to swipe the home button vertically or horizontally to view the running apps.

Swipe the home button in the upwards direction as marked in the above screenshot.

This brings up the running apps. We can swipe through them horizontally.

 

Tap the multi-window icon to launch an app in split-screen mode.

Let’s open the “Contacts” app. This will show up in the upper half.

Tap the Home button and select another app for the lower screen.

“Contacts” and “Play Store” app are running simultaneously in Split-Screen mode.

To disable the split-screen, swipe up/down the screen all the way to the top/bottom.

 

In the “Gesture & Buttons” mode, there is one more way to launch the running apps. Swipe through the home button in the horizontal direction as marked in the above screenshot.

However, the split-screen mode doesn’t work. You can see there is no multi-window icon on the “Play Store” app window

LG K40 Multitasking with Qslide Apps – Mini App Window

There is one more way to multi-task on LG K40. There are few apps that work on top of the current screen in a mini-window. They are known as Qslide apps.

To use Qslide apps, Go to Settings > Display > Home touch Buttons.

Now, tap “Button combination”. We can keep up to 5 home touch buttons. The extra buttons that we can add are Notification (to pull up /down), Capture+ & Qslide.

Drag up the Qslide icon as shown above.

Tap the Qslide home touch button to view the Qslide apps.

There are 6 apps that work in mini-window mode.

They are Video, Phone, Contacts, Messaging, Email & File Manager.

Let’s launch the first app i.e. Video.

We can increase/decrease the size of the window & control the opacity as well.

The Phone app launches the Phone dialer.

The next app on the list is the Contacts app.

The messaging app can be quite useful. It opens a new text window as shown above.

The Email app takes you to the inbox by default.

The last QSlide app on the list is the File Manager as shown above.
