I can’t get the camera to focus on the barcode or QR code about 90% of the time I am trying to scan something. I’ve tried single and double tapping the screen. I’ve tried moving the barcode closer/farther from the camera. I’ve tried different lighting. 90% of the time it refused to identify the code. If I pull up my phone’s default camera app. It focuses and scans near instantly. It’s almost as if the camera’s focus is hard set whenever creator opens the camera function and it doesn’t know how to allow the camera to refocus. 

I’ve also noticed most barcode scanning apps have a line in the middle of the screen to make it easier to focus on a barcode. This is useful when trying to scan a particular barcode when multiple barcodes are visible. When using Zoho’s creator app it randomly scans the first barcode it finds in the camera’s view.
