I just noticed that what I thought was "waveform bars" (for lack of a better description) on my iPhone 6 was actually a miniature landscape of houses and trees. What is it and where did it come from?
I upgraded from an iPhone 4S to iPhone 6S recently, so I'm not sure when I first noticed the issue, but I'm certain that it didn't exist on the iPhone 4. It's definitely not part of the original picture.
EDITED TO ADD: I was wrong. It was in fact part of the "original" picture (the one I uploaded to the phone), created by another program. I hadn't noticed it on the iPhone 4 because of the screen size/screen tilt. I'll leave the question in the slim chance someone else has encountered such a problem, but in any case it's been solved.
ORIGINAL QUESTION CONT.
It's barely noticeable (showing only the tops, which to me look like a waveform) until I tilt the phone, then it becomes apparent what it is.
Searching for quite some time on Google doesn't give me any answers. Anyone have any idea where this came from? I guess I could just change the image to see what happens, but in any case, it wouldn't explain where the image came from. My phone isn't jailbroken, so I'm doubtful it's some sort of malware that's gotten onto it (though not entirely impossible).
