exchanged a 64gig for a 128gig (paid the difference ofc) and got a new in box because of the screen at the bottom being warmer and annoying in landscape and noticeable in portrait and wifi dropping way too many times, while trying network reset and all the software tricks/doing a few reboots. more drops than the first unit i had which in hindsight maybe i should have kept despite the dead pixels and dust and such... the screen wasn't as ugly. the text was also fuzzy on previous one, this one seems smooth like the first.
they were out of 64 gigs new and had to order a genius bar replacement phone that would take days. i didn't want to keep wasting time dealing with this. there were people in the store waiting to buy them but they just pulled a rep from the accessories section to take care of it for me real quick.
this one seems pretty uniform in tint, and clear and cool

i'm not gonna go looking for issues, i'm bound to find them. but i think this is definitely one I can work with. I'm picky!
i'm happy. Every panel could benefit from color profiles but I can make do until JB on this one.
Holy crap. I hate the screen/QC lottery. HATE. nobody wins in the end with it, except
The previous one didn't have a flush sim tray either, this one does. and this is perhaps the first power button that has a nice feel to it imo. again being nitpicky. functionality and viewing prettyness are really my main priorities. I think I'm gonna skip 6s for this reason, don't wanna gamble. Also won't be eligible for the upgrade
good luck everybody! its draining.
