In this guide, you will find all the possible ways to close the background apps on your LG Smart TV.
How to Close Apps on LG Smart TV
The following are the possible ways to terminate the apps running in the background of LG Smart TV.
Using the Close Icon
In the latest version of webOS, all the apps will have the X icon to close the app. If you want to close the app that you are currently using, tap the X icon on the top-right corner of the screen. The app will be closed and won’t run in the background.
To get the X mark on the app, you need to update your LG Smart TV firmware to the latest version (webOS 23).
Using the Back Button on your LG TV Remote
You can also press the Back button on the LG TV remote to close the app. Based on the webOS version of the TV, your LG TV does the following things:
- On LG TV with webOS 5.0 or lower, pressing the Back button will take you to the previous page if it exists or it will launch the Home launcher.
- On LG TV with webOS 6.0 or higher, pressing the Back button twice will prompt you to close the app. Click Exit on the prompt to close the app.
You can also hold the Back button to force close the app on your LG TV.
Using the Home Button on your LG TV Remote
Another method to close all recent apps is by pressing and holding the Home button on the remote. A pop-up will show all recent apps that are already opened and running in the background. To close an app, hover over the app you want to close and click on the ‘X‘ icon to close the app. For instance, if you want to close the All 4 app on LG TV, click the X icon on top of the All 4 app.
If there is any download pending in the app, the download will be paused automatically when you close the app.
Using the Memory Optimizer Function
On newer LG TV models, you can access the Memory Optimizer function to close an app and clear the RAM of your LG TV.
 Click on the Settings button on your LG TV remote.
 Select the OLED Care in the Settings.
 Choose the Device Self Care option.
 Select Memory Optimizer and click Start.
This will close all the apps running in the background on your LG TV.
Note: Memory Optimizer function also helps to delete unused apps on an LG TV.
Soft Reset your LG TV
A soft reset is a useful way to close all the apps on your LG TV without deleting anything. To do this, turn off your LG TV and unplug your LG TV from the power supply. Then, leave it unplugged for more than two minutes.
After that, plug the TV cord back into the power source. Now, turn on your LG TV. It is very beneficial to LG TV since it clears the built-in cache so that you can experience a smooth performance on your LG TV.
Note: If your TV’s performance is abruptly slow after a soft reset, it is better to reset your LG Smart TV to factory defaults. But keep in mind that it will clear the system data and the installed applications.
