How to Fix LG TV “This App Will Now Restart to Free Up More Memory”?
The “This app will now restart to free up more memory” message appears when an LG TV can no longer keep the current app or browser session running safely. webOS closes that session and reloads it, which is why the program stops even though the TV itself may remain on.
The word memory is easy to misread here. The immediate failure concerns the TV’s working memory, while deleting apps mainly frees internal storage. LG recommends both a full power cycle and removing unused apps, but they address different conditions.
What matters first is where the warning appears. A single failing app points toward that app or its saved data, while one troublesome website can exceed the built-in browser’s limits.
If several apps, Home, Settings, or an HDMI input are also interrupted, the problem is wider than one app and may involve webOS, a recent update, or the TV itself.
| Where the restart occurs | What it usually tells you | Use first |
|---|---|---|
| One installed app only | The app package, its current version, or the service itself is the narrower suspect. | Methods 1 and 2 |
| Only one website or the LG browser | The page may be too demanding or use web features that the TV browser does not support. | Methods 1 and 4 |
| Several apps, Home, or Settings | webOS is not recovering cleanly, storage is constrained, or a system-level fault is developing. | Methods 1, 2, 3, and 5 |
| The warning also appears while viewing HDMI | The built-in app is no longer the cause; treat the TV software or hardware as the problem. | Methods 1, 2, and 5 |
LG documents this exact warning in its memory-shortage support guide.
1. Disable Quick Start+ and Give webOS a Complete Restart
Turning an LG TV off with the remote can leave it in quick-start standby. If the same temporary state is preserved, the app may restart again even though the TV appeared to have been switched off.
LG’s procedure for this exact message is to disable Quick Start+, unplug the TV, and reconnect it after 10 minutes. This is more useful than repeatedly closing the affected app because it forces webOS to start a new session.
- Press Settings on the remote, open All Settings, and select General.
The Quick Start+ setting is inside General on supported models. - Find Quick Start+, sometimes labeled Q-Start+. Its location depends on the webOS generation:
- webOS 24/25: System > Additional Settings > Quick Start+.
- webOS 22/23: Devices > TV Management > Quick Start+.
- Earlier webOS versions: Additional Settings > Quick Start+, or Quick Start+ directly under General.
This example uses System and Additional Settings, other models use TV Management or General directly.
- Set Quick Start+ to Off. If the option does not exist on your model, continue with the power cycle rather than opening a service menu.
Leave the setting off while checking whether the memory warning returns. - Turn the TV off, unplug its power cord, and leave it disconnected for 10 minutes.
- Reconnect the TV, turn it on, and reopen the same app or website.
- Continue beyond the point where the warning normally appeared.
Watch beyond the point where the interruption usually occurred.
If the app now remains open, leave Quick Start+ off and check another normal viewing session. If the warning returns, continue with Method 2; the result will determine whether to repair one app or update the whole TV.
2. Update webOS, Then Reinstall Only the App That Fails
A webOS update can correct system stability or compatibility problems, while reinstalling replaces the files of one downloaded app. This separates a damaged app package from a fault in the software that runs the whole TV.
Reinstall an app only if it is the sole downloaded app showing the warning. Do not remove every app when several unrelated parts of the TV are failing.
LG’s software-update guide lists older menu locations and the offline USB procedure.
- Open Settings > All Settings > Support > Software Update on webOS 5.0 and later, then select Check for Updates. On older TVs, use General > About This TV > Check for Updates.
- Install any available update and let the TV finish restarting. Do not unplug it during installation.
- If only one downloaded app still triggers the message, note its login details and confirm that it remains available in the LG Apps store for your model and region.
- Delete that one app, restart the TV, then install it again from Apps or LG Content Store.
- Sign in and repeat the same playback test.
If the app works after reinstalling, its local installation was damaged or stale. If the same service fails on every device, or the LG app started failing immediately after its own update, check the provider’s status and support instead of resetting the TV.
If the affected service is Netflix but the TV shows a different Netflix code rather than this LG memory warning, use the separate Netflix TV troubleshooting guide for that symptom.
If the reinstalled app now works, its local files caused the restart. If the warning returns in several apps after webOS is current, continue with Method 3.
3. Remove Unused Apps and Run Memory Optimizer if the TV Has It
LG also recommends deleting unused apps for this warning. Removing their packages reduces occupied storage, while Memory Optimizer helps supported models clear unneeded active state.
Use this cleanup only when app installations fail, the Home screen is sluggish, or the TV has accumulated many unused apps. It does not add physical RAM.
- Press Home. Move to the end of the apps row and choose Edit App List or Edit Apps List.
The name may appear as Edit Apps List, depending on the TV software. - Select an app you no longer use. If there is no edit button, highlight the app and hold the remote’s OK/Wheel button for about 3 seconds.
The delete control may be a trash can or an X; some built-in apps cannot be removed. - Select the trash can or X, check the app name, and confirm the deletion. Repeat only for apps you do not need.
Check the app name and keep its sign-in details if you may want it again. - If the TV includes Memory Optimizer, run it once. On supported OLED models it is commonly under All Settings > General > OLED Care > Device Self Care > Memory Optimizer. Skip this step if the control is absent; availability varies by model.
- Restart the affected app and test the same content again.
Do not keep deleting working apps once the cleanup makes no difference. If the warning returns only in the browser, continue with Method 4. If it returns in menus or on HDMI, continue with Method 5.
4. Treat a Browser-Only Restart as a Website Compatibility Limit
LG states that a website can be too large for the TV’s memory to process, causing webOS to close the browser or restart the TV. Older webOS browsers can also lack newer web standards even when the internet connection itself is fine.
Use this method only if the TV remains stable outside the browser. It will not repair a restart that also occurs in installed apps or on HDMI.
- Open the LG browser menu, enter Settings, and clear its browsing data if that control is available. This removes saved site data without changing the rest of the TV.
- Open the site again without restoring several old tabs. If the browser offers Private Browsing, use it for the test so the previous session is not reused.
- If the same page still forces a restart, open it on a computer or console with a current supported browser.
Continue only if the website plays correctly in the computer’s supported browser. - Connect that device’s HDMI output to a TV HDMI input. Select the matching input with the TV remote.
Choose the HDMI number matching the cable connection. - On Windows, press Windows + P and choose Duplicate. The Appuals laptop-to-TV connection guide covers the HDMI setup in more detail.
Windows key and P opens the projection choices. - Play the website on the external device while the TV remains on that HDMI input.
If the page works through the external device, the TV browser is the limit; the HDMI method is a workaround, not a browser repair. If the LG warning still appears while the external device supplies the picture, continue with Method 5.
5. Check for a TV-Wide Fault if the Warning Spreads
One app can have bad files, but it cannot explain the LG memory warning appearing over Home, Settings, several unrelated apps, or an HDMI input. A recurrence soon after the official 10-minute power cycle also makes a temporary session less likely.
Comparing unrelated screens isolates the TV because those sources do not share one app package. The record below helps LG distinguish a firmware regression from a serviceable hardware fault.
- Record the full TV model and current software version.
- Write down every place where the warning appears: the app names, Home or Settings, and any HDMI input.
- Note whether it began after a webOS update and how long the power cycle helped.
- Take a photo or short video of the message and any reboot that follows.
- Contact LG Support and ask for model-specific firmware or service guidance.
A factory reset removes accounts, settings, and downloaded apps, but it cannot repair incompatible browser hardware or a faulty mainboard. Use it only if LG recommends it for the model after reviewing the TV-wide symptoms.
If the warning remains limited to one third-party app after webOS is current and the app has been reinstalled, report the app version, TV model, and triggering content to that app’s provider.
If the warning still appears across unrelated screens and inputs, keep the case with LG rather than repeating app reinstalls. At that point, local app cleanup has already been ruled out.
