I think more than a few twists and turns on this subject.
Deviating from the original, Filter to enhance the quality of image ( which used a posted image) to more general images.
Upgrading to a new phone, therefore a different sensor, might change the characteristics of the image.
I would not count on a tablet to provide a suitable backlight. Might work or might not work. A diffuser might be needed.
This is from my phone (ok I know it is out of focus, not doing it again) cropped and straightened 2365x1551 px
..and this exactly the same setup but using my camera, again cropped and straightened 3300x2361 px Same procedure negative -> positive in Gimp.
Apart from the obvious different colour balance, that matrix showing which I assume is the tablet display.
---------
From an earlier question on renaming images. In linux I use gprename.
