Hi, I saw display units of the iPhone 7 in multiple stores and I could see an interlacing screen door effect , also called pixel walk or any of other several synonyms. A known issue on many iPhone 5s 6 and 6s units. Anyone else see it? It's major to me because there looks to be a fine grid over the screen at times and it's most certainly not retina. It's not present on the plus series at all as far as I can tell.
