Question: Q: iPhone 6: Apparent backlight uniformity issue
My new Verizon iPhone 6 64GB exhibits a darker region on the top 1/8th of the display. It is most evident when displaying a white background. It is difficult to tell whether it’s a chromaticity issue (AMLCD issue), a luminance uniformity problem (backlight), or something else all together.
Anyone else notice this effect on their new phone?
iPhone 6, iOS 8, Verizon 64GB

I too have obvious shadowing towards the top of the phone, which is most apparent on white backgrounds. I also have some yellowing towards the bottom sides of the screen, which is more pronounced on the left than the right side.

I’ve got the same issue issue iPhine 6 and its driving me nuts. I’m coming from an iPhone 5s which had a slew of display issues, and was hoping to be spared with these on the 6. The top section of my screen gradually fades to a warmer, yellower colour. It also appears to warmer in the top right than the top left.
I had the same issues with my 5s. The first 5s I received had the exact same problem with a yellowing near the top; I swapped this and received one that wasn’t so noticeable. 8 months later, the screen came loose and had to swap it. This new one had yellowing down the left side when held in portrait mode. That was swapped for one, but with yellowing down the right In portrait. At this point, I wasnt allowed to swap any more as I’d already swapped it twice for non problematic display issues. But, for being good customer, and trying to see me right, I was authorised by the store manager for a CRU — a Customer Replacement Unit — an iPhone fresh from the box, ssealed, with all accessories instead of the normal replacement stock. This too has a yellowing near the top, albeit sutbtly. Even worse, this unit has scan lines running across the screen in portrait mode. After 5 attempts, I went into the display lottery and came out a lose at the other end.
My girlfriends gold iPhone 6 also exhibits the traits, and when compared to mine, looks worse. The one I did check to instore seemed perfect, no gradient whatsoever. Additionally, another friend who has a Space Grey iPhone also didn’t seem to have an issue.
Since I’ve noticed this, I’ve noticed ALL of my other devices have this yellowing, but much more subdued.
My work 27″ iMac (2009) is yellow down the screen.
My 15″ MacBook Pro with Retina display (2013) is more yellow down the screen, as well as to the left.
My iPad (3rd-gen) is also yellow towards the top of the screen, as well as the left hand side.
I’m guessing some form of discolouration is normal, and the idea of display panel uniformity is probably a pipe dream. The problem is, the brief times I did check other iPhones (apart from my girlfriends), I didn’t study for long periods of time and instead compared them to the yellow area of mine. They probably exhibit the same issue, but the whole screen may have a different white point throwing everything off.
I’ll probably try and live with it for now, I’m not going to rush to the Apple Store to swap it – I’ll make an appointment for next time I’m passing by.
After the iPhone 5s, I must be flagged as a «problem customer» by now; but when you’re spending £700 for a device you use everyday, you want it to be as good as it can be.

5 распространенных проблем iPhone 6s и способы их решения
Не было в истории Apple такого анонса, который обошелся бы без скандалов или критики. iPhone 6s не стал исключением и, как мы уже писали, является далеко не первым «яблочным» смартфоном с проблемами. Но случаются и такие трудности, разобраться с которыми самостоятельно получается далеко не всегда. Как же устранить большинство распространенных затруднений, связанных с iPhone 6s?
Аккумулятор
Первой в нашем списке и далеко не последней по важности является проблема автономности «эски». Так называемый “Batterygate” преследует многих пользователей, заставляя их заряжать свои устройства по несколько раз в день.
Если производственный брак исключен, попробуйте заглянуть в появившийся в «Настройках» раздел «Аккумулятор». Там вы увидите полный отчет системы обо всех энергозатратных процессах. Будет крайне полезно узнать, какое из приложений является самым «прожорливым». Если ничего выявить не удалось, обязательно отключите автоматическое обновление ПО. Для этого войдите в «Настройки» — «Основные» — «Обновление контента» и переведите тумблер в положение «выкл». Что интересно, Plus-версия лишена подобного недостатка и «живет» крайне долго. Кроме того, в iOS 9 пользователям стал доступен режим энергосбережения.
Зависания интерфейса
Эта проблема является не столь распространенной, как вопрос автономности. Причем с подобной оказией, как правило, сталкиваются только пользователи iPhone 6s. S-Plus работает куда стабильнее. Для того чтобы вывести систему из «обморочного» состояния, используйте «мягкий» сброс удерживанием кнопки «Домой» и клавиши включения. Если фризы и зависания случаются слишком часто, попробуйте сбросить все настройки и восстановить данные из резервной копии. В противном случае обратитесь к производителю и получите взамен исправный смартфон.
Ложные срабатывания 3D Touch
Новая версия технологии Force Touch, дебютировавшей в Apple Watch, как выяснилось, далеко не всегда работает корректно. Инженеры iFixit утверждают, что если вас постигла подобная неприятность, вам, скорее всего, придется менять iPhone. В большинстве случаев ложные срабатывания имеют место при нарушениях аппаратного обеспечения устройства. Но для начала все-таки проверьте в «Настройках», включен ли режим 3D Touch, и убедитесь в чистоте поверхности экрана.
Перегрев корпуса
Удивительным качеством обладает большинство устройств от Apple. То ли все дело в оптимизации, то ли в секретной технологии производства, но гаджеты на iOS редко были подвержены перегревам. Исключения составляли только The New iPad с Retina-дисплеем и iPad mini 2, «железу» которых было трудно справиться со столь высоким разрешением экрана. Однако и iPhone 6s оказался подвержен так называемому «эффекту печки».
Попробовать устранить эту неприятность можно самостоятельно. Для начала убедитесь, что в последнее время вы не запускали требовательных к ресурсам игр и приложений. Также возможно, что в фоновом режиме у вас беспрестанно работает энергоемкая программа, которая заставляет процессор нагреваться. Мы настоятельно рекомендуем вам проследовать в «Настройки» — «Аккумулятор» и проверить все активные процессы. Если ничего подозрительного обнаружить не удалось, выполните старый добрый сброс настроек и восстановитесь из резервной копии.
Горячая клавиша «Домой»
Последняя в списке, но не последняя по важности особенность iPhone 6s – это раскаленная кнопка Home со встроенным сканером Touch ID 2.0. Как и в случае с проблемным модулем 3D Touch, вам, вероятно, достался бракованный образец. Рекомендуем обратиться к продавцу и заявить об имевшем место затруднении. Не оставляйте проблемы без внимания, тогда устройство прослужит вам верой и правдой.
