I searched a photo editor, which can save cropped pictures with its original resolution, for a long time.
And I didn't know that I had an app for this on my phone for some time
'Photo Enhance Pro'
What I had to do, was to set its image quality to 'Very high'.
I did successfully try with 8MP pictures of my stock camera.
And I will try with larger imported pictures
EDIT: OK, I did it successfully with a 12MP picture of my Canon cam
