A. Ensure that your device's camera lens is clean and unobstructed. A dirty lens can affect scanning speed and accuracy. Additionally, make sure you are in a well-lit area and that the object you are scanning is not too far away or too small.

B. If the scanning process remains slow, try closing other apps running in the background to free up system resources. You can do this by double-tapping the Home button (or swiping up from the bottom of the screen) and swiping up on any unnecessary apps.
