The phone is fine for the most part. I got it via IUP from 6s Plus. The hissing is there when it records video (much more prevalent than my bros matte 7+ 128gb), and the top right of the screen has some abnormality. It's like a black adhesive or tape or something that has ever so slightly gone over the corner. I'll attach some pictures below to show what I mean. I would care slightly less if it was on the bottom corners but when it's on the battery icon corner, I get a little annoyed of this small defect every time I look at the juice level. What do y'all think? Should I replace the phone or hold out till the 8, a year from now?
