@BronzeAgeHogCranker @sickburnbro That would be an incredible feat of retardation if the iPhone's upscaling algorithm did *that*, although it's not literally impossible.

The artifacts in those letters are something that occur in applications very far removed from anything I do regularly - I've seen this type of thing in medical imaging applications, where the point is that you have very low resolution *because increasing the resolution requires pumping your patient full of radiation*. There's no excuse for a consumer phone to be doing this, and if it *is* then Apple has an Engineer to fire.
