Thank you. Unfortunately, it seems that OpenScan does not have the feature to straighten out photographed documents. Cammscanner has its own camera app, which has features specific to photographing documents.
I absolutely love Camscanner, and I have been for over a year on the old version because I refuse to update to the new version which requires network permissions. I exactly suspected this is why it needs those permissions.
To what did you switch? Camscanner is otherwise an excellent app, especially for combining multiple images and straightening them out.
Adobe has lost my trust years ago, and I see that viewpoint vilified often enough to never use Adobe software again. The only Adobe product that I still use is Magento, and only that on client sites. I would love to find a non-Adobe alternative.
