A. Force close the app by double-tapping the Home button (or swiping up from the bottom of the screen on newer iPhones) and swiping up on the Blippar app to close it. Then, reopen the app to see if the freezing issue persists. If it does, try restarting your iPhone by holding down the power button and sliding to power off, then turning it back on.

B. Check for any available updates for the app in the App Store. Developers often release updates to fix bugs that may cause freezing. If the app is up to date, consider uninstalling and reinstalling it to clear any corrupted data.
