Took my umpteenth iPhone 6 in for a bright white spot in the middle of the screen down the right (many of my 6's have had different issues, I could get into that later, don't want to type more than I need to) Really annoying. Other one had a hot dead pixel (not fixable), a white pixel you could see at off angles, and touch ID that stopped working screen was nice though and the replacements I've had in between haven't been up to par in terms of screen. The genius replaced it, we compared iPhone 6's, he observed his was noticeably brighter at max brightness and had another genius confirm. Sent it back and got another one out, looked identical to previous, dimmer and sorta yellow/cast of something. He compared some employees phones in the back and saw some way worse than the two replacements he took out of the box and declared as not right. None of the employees noticed probably because its the main and only screen they've been staring at. Or they don't care. or something! The third he said I'd have to sort of deal but not angrily, just like this is a bummer man but.. (but I didn't push ever, he really was the one that observed brightness when that wasn't my key concern and kept swapping for that, I was all for it) if it was the same cause of variation. Luckily, it reminds me of the one I had that was great, dead pixels aside (obvious next to lock screen too, lit up) and touch ID mostly not working. He said he even preferred mine to his, and I tended to agree, his was a bit on the pink hue side though not bad. Anyways long story short, this beast is bright! back to rocking low brightness and doing fine. It's going to be fantastic for battery. And shame on for continuing to pull this display crap. Maybe I'll just ride iPhone 6 til it can't be any more then re-evaluate my options. DISPLAY IS IMPERATIVE IMO so glad I got a rMini right away that I deemed fine enough without any swaps, and with Color Profiles (jailbroken) looks great only upgraded from iPad3 to rMini as soon as jailbreak came out, so I had out of box tweaking made possible to cool off the tint a little. My iPhone 5 looks dingy compared to my 6. Sad when some replacements looked dingy compared to my 5, and it wasn't even the creme de la creme of screens, it was a craigslist one I acquired after selling iPhone 5 last fall and doing Nexus 5 thing for a bit. ---- tl;dr lots of crappy screens as always, screen lottery, I think I might have won this time (you only lose if you waste all the time and don't get the results) but I'm getting close to being done with this practice all together. Ruins the enjoyment/experience almost, and for some situations, does. Also, some geniuses out there are level headed. If you aren't a jerk, some of them will be the catalyst for seeing results. Couldn't be happier with the level of service I got today, whether or not this replacement is finally good to go. I sure as hell hope so .
