Camera without auto-focus

Unfortunately, the scanning process cannot work without a good enough auto-focus camera.
It produces blurry images when shooting at close distances, which makes it difficult for the app to recognize numbers and letters.
On the other hand, devices with auto-focus cameras produce images that are sharp and clear enough for scanning.
If your device doesn’t have a good enough camera, you can use the Math calculator to type in any math problem.
