Have you seen the message “This app will now restart to free up memory” on your LG Smart TV when using apps like Netflix, YouTube or web browser? You’re not alone. Many LG TV owners face this frustrating issue with apps suddenly closing and restarting.

In this comprehensive guide, I’ll explain 13 proven fixes to stop your LG TV from repeatedly restarting apps.

What Causes LG TV Apps to Keep Restarting?

There are a few common triggers for LG Smart TV apps repeatedly closing and showing the “This app will now restart to free up memory” message:

  • Insufficient Storage Space: Too many apps or files filling up limited internal memory can prevent apps from running properly.
  • Faulty App Updates: Buggy app updates like a recent YouTube TV update can cause crashing issues.
  • Outdated LG webOS: Using older TV software can lead to app stability problems.
  • Too Many Background Apps/Processes: Lots of apps/processes running simultaneously take up RAM needed to run foreground apps.
  • Weak WiFi Connection: Choppy Internet prevents apps like Netflix from streaming smoothly.

Fortunately, there are some quick troubleshooting steps you can try to stop your LG TV apps from constantly restarting or freezing.

Fix 1: Power Cycle Your LG Smart TV

Start troubleshooting by power cycling your LG TV:

  1. Unplug TV power cable from electrical outlet.
  2. Press and hold power button on TV for 30 seconds (releases stored energy).
  3. Wait 1-2 minutes before plugging power cable back in.
  4. Turn on LG TV and check if apps keep restarting.
Unplug The TV

Power cycling forces a hard reboot, clearing any corrupt data or cache files causing app crashes. It essentially functions as a “reset button” for your LG Smart TV software.

Fix 2: Turn Off the “Quick Start+” Feature

LG’s Quick Start+ feature keeps your TV in a standby low power state so it starts faster when turned on. But this can consume system resources needed to run apps smoothly.

To turn off Quick Start+:

  1. Select Settings > All Settings > General
  2. Select Power > Quick Start+
  3. Change setting from On to Off

With Quick Start+ disabled, more RAM should be available for streaming apps, reducing restart errors.

Fix 3: Clear Browser Cache and Data

Large cached data files from the LG web browser can contribute to limited storage space errors:

To clear browser data:

  1. Launch web browser app and click top right menu > Settings
  2. Scroll down and select Clear Browsing Data
  3. Choose cookies, cached images/files and other data > Clear
  4. You can also enable Private Browsing mode to prevent caching.

Clearing temporary browser data frees up storage for smooth app performance.

Fix 4: Uninstall Unused Apps

Too many unused apps wasting storage space can trigger the LG TV restarting apps message.

To uninstall apps:

  1. Go to LG TV home screen and select the app icon ribbon.
  2. Scroll all the way right to Edit Mode and select the delete X icon on unneeded apps.
  3. Confirm uninstall when prompted on each app.

Removing inactive apps gives active streaming/media apps the storage and memory they need.

Fix 5: Check for LG webOS Software Updates

App crashing issues are sometimes fixed in LG webOS updates.

To manually check for the latest LG smart TV software version:

  1. From Settings, select All Settings > General > About This TV > CHECK FOR UPDATES
  2. If an update is available, select download and install.

Updating to the newest LG webOS version can resolve app instability problems after changes.

Fix 6: Use LG TV Memory Optimizer

For LG OLED TVs, run the built-in Memory Optimizer for additional app crashing fixes:

  1. Go to Settings > All Settings > General > OLED Care > Device Self Care
  2. Select Memory Optimizer > Start to clean up junk files

This deep cleans storage by removing temporary unused app files no longer needed.

You can also use an external streaming device like Roku or Fire TV instead of the built-in LG software.

Fix 7: Reset Your LG TV to Factory Settings

If other troubleshooting steps don’t stop the constant app restarts, a factory data reset clears all stored app data:

  1. Select Settings > All Settings > General > Reset to Initial Settings > OK to confirm.
  2. Complete the initial first-time installation process when powered back on.
Reset To Initial Settings

Resetting removes any corrupted data/files that can cause LG TV apps to crash.

Fix 8: Connect TV to Wired Internet vs WiFi

Choppy WiFi connectivity can disrupt video streaming and cause buffering issues that crash apps.

For smoother 4K streaming, connect your LG TV to your modem/router using an Ethernet network cable. This circumvents any WiFi interference interrupting app functionality.

Fix 9: Close Background Apps

Too many apps running simultaneously, especially resource-intensive video streaming apps, can overload available RAM needed for active foreground apps.

Close background apps not in use:

  1. While on an active app, press and hold the Home button on your LG Magic Remote.
  2. Scroll left/right and select close X on each background app shown.

Freeing up RAM allows your active LG TV app ample memory to run without restart errors.

Fix 10: Disable Auto App Updates

Some app updates automatically installed can occasionally break functionality and cause crashing issues.

Disabling auto updates prevents buggy releases from creating problems:

  1. Go to Settings > All Settings > General > System Update
  2. Turn Auto Update Apps setting from On to Off

This stops problematic app updates from automatically being applied before they are patched.

Fix 11: Adjust App Background Refresh Settings

Restricting background app data/info refresh reduces system resource usage allowing apps to run smoother:

  1. Go to Settings > All Settings > Apps > Background App Refresh
  2. Disable background data refresh completely or select apps to exclude.

Limiting background refresh only to essential apps prevents overloading RAM.

Fix 12: Contact LG Support

After trying the previous troubleshooting tips, reach out to LG Support as another resource if your apps still frequently restart.

LG experts can help diagnose if the recurring app crashes require hardware repairs or replacements under warranty:

  • Phone: Call 1-800-243-0000
  • Online Support Ticket: Visit LG USA Support
  • Support Chat: Initiate a live chat session

Getting assistance can uncover additional solutions for fixing constant app restarts.

Fix 13: LG TV Memory Upgrade

For older LG TV models still seeing frequent app restarts/freezing even after troubleshooting, upgrading internal storage provides more memory:

  • Use a USB flash drive or external SSD connected to your LG TV’s USB port for expanded app/media storage.
  • Install higher capacity RAM memory chips for increased speed/performance.
  • Adding an external storage drive or replacing built-in RAM chips restores smooth smart TV functionality.

Upgrading outdated, limited LG TV storage resources can resolve app crashing issues.

FAQs About LG TV App Restarts

What is the LG TV “this app will now restart” error message?

This is a warning message shown before an LG TV app forcibly closes itself to clear memory resources so it can restart. It indicates insufficient storage or system memory available currently to keep running properly.

Why won’t Netflix stop crashing on my LG TV?

Constant Netflix crashes on an LG TV usually indicate WiFi connection problems, lack of storage space, too many background apps running, software bugs, or hardware faults like bad RAM chips or motherboards.

Why does YouTube keep restarting on my LG Smart TV?

Frequent YouTube app restarts on an LG TV can be caused by the app’s recent buggy software updates requiring a rollback. Also storage and memory constraints or software corruption can cause incessant crashing.

What is an LG TV factory data reset and will it stop apps from restarting?

An LG factory reset erases all app data and custom settings, restoring the TV back to default out-of-the-box configurations. This wipes any corrupted data that can trigger app crashes so apps have a “clean slate” to function normally again.

Key Takeaways: Stop LG TV App Restarts

  • Common triggers like insufficient storage, faulty updates, too many background apps or WiFi issues cause LG TV app crashes.
  • Power cycle TV, turn off Quick Start+, clear browser data and remove unused apps to free up storage space.
  • Check for LG webOS TV firmware updates, run Memory Optimizer cleaner and reset TV to factory settings to fix software issues.
  • Switch to wired Ethernet, close background apps, disable auto updates and manage background data to optimize performance.
  • As a last resort, upgrade RAM/storage or contact LG Support for replacement options to handle hardware limitations.
