Am doctor who takes a lot of pics of documents. It's really disappointing, my iphone 13 did take better pics I guess. The pics are blurry on edges. Hope software update resolves the issue. Am posting an image for reference. You can clearly see the upper line of print which is blurry.
While taking photos of a Document click on that T icon button . You will see Yellow Rectangle and adjust the side. You will get a perfect Document. Just Try.....If this help you accept as a solution.
This was when there was an yellow box surrounding the page. The problem still persists.
