That means the phone is smart. Recording what your're talking, then it recommends videos, ads and similar according to you. Dunno, I don't like old phones as sound isn't that good and from new ones ( Do like flip phones, like my fav Motorola V60 ), only those Chinese Spyphones are good ( do like those, radius of mic is 30cm max I think haha excludes everything else. Even roaring KTM Duke, so go figure ). But anywho... Was thinking that you've used not camera device to take images. Don't think that white background is helping. If it's to soak the light you could just put that paper in the frame, that is usually enough. Never had true luck with it.
