A. 1. Close background apps: Ensure that no other apps are running in the background that could be consuming resources. 2. Clear app cache: Go to Settings > Apps > Vaia > Storage > Clear Cache to remove temporary files that may be causing the freeze.

B. 3. Reduce the number of flashcards: If you have a large set of flashcards, try reviewing a smaller subset to see if that resolves the freezing issue.
