Dear Alyaw
I am using iPhone 14 Pro Max - with 3 Cameras
In November - only built In Camera APP was able to create pictures below 10-15cm distance.
All other apps where not able to Zoom in, it got blurry.
So I called Apple Support. After some back and forth, Apple explained: App Developers must switch from one lens to the other them self - its duty of the App.
I am using by Example ABBYY BCR (i am user, so nothing to do with this company beside of using it), and it was NOT able to take readable picture of any Business Card - not even with 10-15cm, never got readable/sharp in November. Same test in December, I can get as close as 5cm and get a super sharp picture, even beeing able to see structure. Same thing with WorldCard, which is working as well since now.
As a comparison, ScanBizCards is still not able to take any sharp picture below 15cm and therefore is useless.
If you look for QR Codes or BarCodes, tools like "Quick Scan" and "QR-Code" still are useless due to this problem. And Reality above proofs, if you look at QRbot, where you can See in Settings - Camera - there are all of the 4 (if you do use a standard 14, 3) Cameras can be seen. Once I switched to "Backsid Ultra Wide", I get super Sharp pictures and it reads Barcodes and QR-Codes like a charm.
--> So YES this App proofs - its up to the App to decide which CAM to use from my learning.
I hope this helps everyone which needs QR/BarCode Readin or is looking for Business Card reading.
Apples Advise: conntact your "App Provider" letting him know about the problem.
If you paid, and it does not work anymore, no reaction - then give him the raiting he deserves for not maintaining his app.
