A. 1. Ensure you are using high-quality images with clear subjects. The app performs better with well-lit and high-contrast photos. 2. Try adjusting the image's brightness and contrast before using the background removal tool. You can do this within the app or using another photo editing app. 3. Use the manual adjustment tools provided in the app to refine the edges after the automatic background removal.

B. 4. Experiment with different backgrounds to see if the app performs better with certain types of images. 5. If the automatic tool fails, consider using a different app for background removal and then importing the image back into Pixelcut for further editing.
