Pixel 6 phone running Android 13 (same problem with Android 12). Also did not work with Windows 10 and a webcam, or GalaxyTab 6 (dont recall the Android version)
I have tried to scan several barcodes, including books, kimwipes, canned air. The scanner flashes white and does not change upon the horizontal line going across the barcode. It does not matter if you fill out the form or not.
