A. 1. Restart your device: Sometimes, a simple restart can resolve temporary glitches. Press and hold the power button, select 'Restart', and wait for your device to reboot. 2. Clear the app cache: Go to 'Settings' > 'Apps' > 'KCL' > 'Storage' > 'Clear Cache'. This can help remove any corrupted data that might be causing the freeze. 3. Reinstall the app: If the issue persists, uninstall the app by going to 'Settings' > 'Apps' > 'KCL' > 'Uninstall'. Then, reinstall it from the Google Play Store.
