Featured Snippet: To resolve Samsung Good Lock modules crashing, start by checking module compatibility with your One UI version. If a module is incompatible, wait for an update or uninstall it. For persistent crashes, force stop the module and clear its cache (Settings > Apps > [module] > Storage > Clear Cache)[reference:1], update Good Lock and all modules from Galaxy Store[reference:2], or uninstall and reinstall the problematic module. If Good Lock itself won’t open, uninstall and reinstall the app[reference:3].

Why Samsung Good Lock Modules Crashing Occurs

Several factors can cause Good Lock modules to crash. According to Samsung’s troubleshooting guides and community reports, the issue is often related to One UI version compatibility, corrupted cache, or system-level conflicts.

Here are the most common reasons why Good Lock modules fail to work:

  • One UI Version Incompatibility: Major One UI updates often break compatibility with Good Lock modules[reference:4]. Samsung has confirmed that eight popular modules—ClockFace, Game Booster+, Home Up, LockStar, MultiStar, NavStar, NotiStar, and QuickStar—are not yet compatible with One UI 9.0[reference:5][reference:6].
  • Corrupted Module Cache: Over time, modules accumulate cached data. If this cache becomes corrupted, the module may crash[reference:7].
  • Outdated Good Lock or Modules: Running older versions of Good Lock or its modules can cause instability[reference:8].
  • Good Lock Theme Conflicts: Keyboard themes or customizations installed through Good Lock modules can cause crashes if they haven’t been updated for your One UI version[reference:9].
  • Battery Optimization: Aggressive battery management can prevent Good Lock modules from running properly in the background.
  • Corrupted System Files: Rarely, underlying system file corruption can cause Good Lock modules to malfunction persistently[reference:10].

💡 Quick Tip: Start by checking module compatibility with your One UI version—this resolves Samsung Good Lock modules crashing for many users.

Method 1: Check Module Compatibility with Your One UI Version

Major One UI updates often break compatibility with Good Lock modules[reference:11]. If you have recently updated your device, module incompatibility is likely the cause of Samsung Good Lock modules crashing.

    • ClockFace
    • Game Booster+
    • Home Up
    • LockStar
    • MultiStar
    • NavStar
    • NotiStar
    • QuickStar

  4. If a module is incompatible, uninstall it and wait for a compatibility update[reference:14].

⚠️ Important Warning: Samsung has confirmed that all Good Lock modules will be compatible by the time the stable One UI 9.0 release goes public[reference:15]. In the meantime, avoid using incompatible modules to prevent crashes.

Method 2: Force Stop and Clear Module Cache

If a specific module is crashing, force stopping it and clearing its cache is often the quickest fix. According to Samsung’s support, clearing the cache (not data) for the module is a recommended first step[reference:16].

  7. Test if Samsung Good Lock modules crashing is resolved.

✅ Expected Result: Updating Good Lock and all modules resolves Samsung Good Lock modules crashing caused by outdated software.

  4. Restart your phone.
  5. Open Good Lock and reinstall the module from the module list.

  2. Find Good Lock.
  3. Tap Uninstall.
  4. Restart your phone.
  5. Open Galaxy Store and reinstall Good Lock.

  1. Press and hold the Power button.
  2. Tap and hold the Power Off option.
  3. Tap Safe Mode.
  4. Once in Safe Mode, open Good Lock and test the crashing module.
  5. If the module works in Safe Mode, a third-party app is causing the conflict.
  6. Restart normally and uninstall recently installed or suspicious apps.
  7. Test Good Lock after each uninstall to identify the culprit.

✅ Expected Result: Removing conflicting apps resolves Samsung Good Lock modules crashing.

Method 8: Reset All Settings

✅ Expected Result: Resetting all settings resolves Samsung Good Lock modules crashing caused by corrupted system preferences.

Method 9: Wipe Cache Partition from Recovery

  3. Release both buttons when the Recovery Mode menu appears.
