A. 1. Restart your device: Sometimes, a simple restart can resolve app crashes by refreshing the system resources. 2. Clear app data: Go to Settings > Apps > Oxygen Advantage > Storage > Clear Data. This will reset the app to its original state, but you may lose any unsaved progress or settings. 3. Check for updates: Ensure that both your device's operating system and the Oxygen Advantage app are up to date, as updates often include bug fixes.

B. 4. Uninstall and reinstall the app: If the problem persists, uninstall the app from your device and then reinstall it from the Google Play Store. This can help eliminate any corrupted files.
