Examples of good and bad full-screen sample photos:


Good photo.


Good photo. Upper and lower borders are somewhat cropped, but the markers are still in the photo


Good photo. When it is not possible to adjust all the borders to the edges of the photo, it is ok to take picture so that at least one horizontal and one vertical border be adjacent.



Unusable: Sample picture takes much less than the whole photo size.



Usable, but with some problems: There is a foreign object in the screen - it is recomended to avoid such objects.
