Check What Is Causing the Problem
Before you start changing settings, it helps to identify whether the issue affects all apps, a single app, or only certain functions like streaming or loading. A webOS update can sometimes introduce compatibility problems with older app versions, change network settings, or clear cached data that apps rely on.
Try opening a few different apps to see if the problem is widespread. If only one app fails, the cause is likely that app’s compatibility with the updated webOS version. If all apps fail to load, show error messages, or crash immediately, the issue is more likely related to the system or network.
Possible causes after a webOS update include:
- Corrupted app cache or data
- Outdated app versions that are not yet compatible with the new webOS build
- Network settings that were reset or changed during the update
- Smart Hub (the app launcher) needing a reset
- A temporary software glitch that a simple restart can fix
Fixes to Try in Order
Work through these steps from simplest to more involved. Test your apps after each step before moving to the next.
1. Restart the TV Completely
A full power cycle clears temporary system errors that may have been introduced during the update. Do not just put the TV to sleep; unplug it from the power outlet for at least 60 seconds, then plug it back in and turn it on. This forces the operating system to reload fresh.
2. Check Your Internet Connection
An update can sometimes alter network settings, such as switching from Wi-Fi to Ethernet or losing the saved password. Go to the TV’s settings menu and verify that the network connection is active. Run a network test (often found under Settings → General → Network → Network Status). If the test fails, reconnect to your Wi-Fi network or check the Ethernet cable. If you use a VPN or proxy, try disabling it temporarily because webOS updates may not interact well with certain network configurations.
3. Update the Problematic Apps
When an app stops working after a system update, the developer may have already released a compatibility patch. Open the LG Content Store (or app store on your TV), navigate to My Apps, and check for updates. If an update is available, install it and then try launching the app again.
4. Clear App Cache or Data
Some webOS versions allow you to clear cached data for individual apps. This can resolve issues caused by corrupted temporary files. The exact location of this setting varies by webOS version, but you can usually find it by going to Settings → General → Apps (or Applications) → select the app → Clear Cache. If you also see a “Clear Data” option, note that this will remove app settings and login information, so you will need to sign in again. Use this option only if clearing the cache alone does not help.
5. Reinstall the App
If clearing the cache does not work, uninstall the app and install it again from the LG Content Store. This gives you a fresh copy of the app that is compatible with the current webOS version. To uninstall, go to the app launcher, highlight the app, press and hold the OK button (or use the options menu), and select Delete. Then install it again from the store.
6. Reset Smart Hub
LG TVs running webOS have a feature often called “Reset Smart Hub” or “Reset to Initial Settings” within the Smart Hub menu. This resets the app launcher, clears all app data, and removes your accounts – but it does not affect your picture settings or other TV configurations. The procedure can vary by model and webOS version, so look in Settings → General → System (or Support) → Reset Smart Hub. You may need to enter a PIN (default is usually 0000). After the reset, you will need to sign in to your LG account again and reinstall any missing apps. This step often resolves persistent app failures after a major update.
7. Factory Reset the TV
If none of the above steps work, a factory reset returns the TV to its original software state. This will erase all settings, accounts, installed apps, and personalized preferences. Use this only as a last resort. To perform a factory reset, go to Settings → General → Reset to Initial Settings (or Factory Reset). Confirm the action and wait for the TV to restart. After the reset, you will need to set up the TV as if it were new, including signing into your LG account and reinstalling apps. Once the setup is complete, install any pending system updates and then try the apps again.
If the Problem Continues
If you have tried all the above steps and apps are still not working, the issue may be caused by a specific bug in the webOS version installed on your TV. Check if LG has released a new firmware update since the one that caused the problem. Go to Settings → Support → Software Update → Check for Updates. Install any available update and restart the TV.
If no update is available, contact LG customer support. Provide them with your TV model number, the current webOS version (found under Settings → General → About This TV), and a description of the symptoms. They may be able to advise on a workaround or confirm whether a fix is in development.
Frequently Asked Questions
Why did my apps stop working after the webOS update?
System updates can change background services, clear temporary data, or introduce incompatibilities with older app versions. The update may also reset network settings or corrupt cached files. These are common, temporary side effects that can usually be resolved with the steps above.
Will a factory reset delete my installed apps and accounts?
Yes. A factory reset removes all apps, signed-in accounts, custom picture settings, and saved Wi-Fi networks. You will need to set up the TV again from scratch. Only perform a factory reset after trying simpler fixes.
How do I reset Smart Hub on an LG TV?
The exact menu path depends on your webOS version, but generally you can find it under Settings → General → System (or Support) → Reset Smart Hub. You may be prompted to enter a PIN. After the reset, the TV will restart and you will need to sign in and reinstall apps.
Do I need to reinstall every app after a Smart Hub reset?
Yes. Resetting Smart Hub removes all installed apps and their data, so you will need to download them again from the LG Content Store. Your TV’s picture settings and other system preferences are not affected.
Can a weak Wi-Fi signal cause apps to fail after an update?
Yes. If the update changed any network settings, or if your router restarted around the same time, the TV may have a weaker or unstable connection. Run a network test in the TV settings to check signal strength. Temporarily moving the TV closer to the router or using a wired Ethernet connection can help isolate the issue.
Conclusion
App problems after a webOS update are usually caused by temporary glitches, outdated app versions, or network changes. Start with a full power cycle, check your internet connection, and update or reinstall the affected apps. If those steps do not work, resetting Smart Hub or performing a factory reset often resolves deeper software conflicts. Be sure to check for further firmware updates from LG, as they may release a patch for known issues. If the problem persists, contact LG support with your TV model and webOS version for specific assistance.
