A. 1. Restart the app: Close the Umax app completely and reopen it. This can clear temporary glitches that may cause freezing. 2. Clear app cache: Go to your device's Settings > Apps > Umax > Storage > Clear Cache. This can help resolve issues caused by corrupted cache data. 3. Check for updates: Ensure that you have the latest version of the app installed. Go to the Google Play Store, search for Umax, and update if necessary.

B. 4. Free up device resources: Close other apps running in the background to free up RAM. This can help improve the app's performance during scanning.
