Scanned document is blurry on iOS Files App

If you go with your iPhone (I use my iPhone 12 and Xs) -> Files, top right 3-dot button -> Scan Documents, scan an A4 size page with full of text. Use manual or auto mode doesn't matter

The result is very blurry.

It is even blurrer than I just take a picture using the Camera app.

I think the Files app is using 2x lens to taking the scan, weird it is wrong! This is wrong, Apple developer!

You need to use the default lens 1x, since the user can bring the device closer to the paper.

More closer more accurate and more sharp for scanning! (A very anti-pattern design, obviously)

Okay then, solve the problem please. Don't ask silly questions, like which cloud drive are you using? Which system are you using, which device, blah, blah...

Try yourself and find the issue.

Steve won't ask question and can always get the jobs done!
