    iPhone 8, iPhone 8 Plus, and iPhone X models that have been repaired with a new display by an unauthorized third-party repair outlet are affected by a problem where the fix seems to disable the device's ability to adjust brightness automatically, according to report from Engadget and Motherboard.

    The issue appears to impact replacement displays installed by non-Apple certified repair shops even when using genuine Apple parts, and it seems to be related to the functionality of the ambient light sensor. It is not a problem that affects display components replaced by Apple or an Apple Authorized Service Provider.

    According to Engadget, the aftermarket repair community has confirmed the issue in multiple countries and in several versions of iOS, including iOS 11.1, iOS 11.2, and iOS 11.3. Engadget also experienced the bug first hand after swapping the displays of two new iPhones, which disabled the ambient light sensor of the devices.
    It is not known if the disabling of the ambient light sensor after a display replacement is a feature or a bug, because there is precedent for iPhone features to be disabled following unauthorized repairs. As an example, after Touch ID was introduced, users who had their Home buttons and Touch ID sensors repaired by non-Apple technicians saw Touch ID disabled.

    This was known as the "Error 53" issue, and Apple at the time confirmed that it was intentionally disabling Touch ID following unauthorized third-party repairs using non-original components because of security and validation issues. Error 53 initially bricked iPhones, which Apple said was in error and fixed, but to this day an unauthorized Touch ID repair will disable the Touch ID sensor on an affected device.

    Repair outlets that spoke to Engadget suspect that Apple may be using the ambient light sensor as a "test-case" to control the repair process and "link hardware with logic boards so if [an iPhone is] repaired outside of the Apple network it loses functionality," but this has not been confirmed.
    Apple has not yet commented on the ambient light sensor issue affecting iPhone 8, iPhone 8 Plus, and iPhone X models repaired by non-Apple service providers, and there is also a separate but unrelated bug that appears to be impacting some iPhone 8 displays.

    As discovered yesterday by Motherboard, some iPhone 8 and 8 Plus models that have had aftermarket display replacements are experiencing issues following the release of iOS 11.3, which appears to have disabled touch functionality in the repaired devices.

    One repair shop told Motherboard that the issue has caused "over 2,000 reshipments." "Customers are annoyed and it seems like Apple is doing this to prevent customers from doing 3rd party repair," said the shop owner.

    The iOS 11.3 bug seems to be related to a small microchip in the display, which disables touch functionality following the update. Repair shops have discovered a fix, but each affected iPhone must be re-opened so the chip can be upgraded, which is a hassle. Motherboard also learned that it's "an absolute nightmare" for unauthorized shops to repair iPhone X components, with the front camera and Face ID components unable to be repaired by aftermarket shops entirely.

    For end users who don't want to hassle with non-functional iPhone components, Apple's message is clear: visit an Apple retail store or an Apple Authorized Service Provider to avoid serious issues. For devices out of warranty, authorized repairs can be prohibitively expensive, however, which leaves customers with limited options.

    These reports of repair issues come as Apple works to fight "Right to Repair" legislation in multiple states, which would potentially require smartphone manufacturers to provide repair information, replacement parts, and diagnostic tools to both product owners and independent repair shops.

    I think you'll find unauthorized repairs can break all kinds of things. :)

    Doesn’t impact me. I’ve turned off that annoying automatic brightness thing. Still not cool on Apple’s part!

    So is the law changing, or has it already changed, where Apple have to allow 3rd party repair places the ability to obtain genuine Apple parts.
    Just like a local garage can buy genuine car parts to repair you car for you in a local garage?

    Well, I broke my iPhone SE screen a couple of days ago and ordered a new screen from iFixit. The first one I had an issue with the light sensor. I complained them and they sent me a second replacement. And guess what? The second one also didn't work. I thought maybe the connector has some issue... and... nope, I took out the original flex cable and glued it to my new screen and the light sensor started to work again.

    I went to Settings - General - Display Accommodations (uploaded a screenshot) and iOS have actually disabled the light sensor when I connect both of my 3rd party flex cable which I have it around here... The slider disappeared.

    I know the article states iPhone 8, but it's funny that I have exactly the same issue with my iPhone SE...

    I had my 8 Plus screen replaced for a hot pixel issue. After the Apple Store replaces the screen it failed the diagnostic check due to the ambient light sensor. They gave me a new iPhone. So I think the issue is not just limited to third-party repairers

    Authorised repairs can break all kinds of things too. What's your point?

    Not shocking to me. When I worked for Apple retail, we had to input the serial number of the new display into their system, and run it through a calibration for the auto-brightness and several of the sensors. I always wondered how third-party shops handled this, since the software for calibrations was apple confidential.

    Apple, please publish a white paper on how to replace parts properly.

    I really can’t fault people for using third party repair options with some of Apple’s prices

    It’s bad on Apple’s part if they’re disabling functions on people’s gadgets to get customers to go into their stores.

    Have had really good customer service from Apple in the past but have had recent trouble with my iMac.

    It’s been a fortnight now and they’ve only had the decency to call me once about it and when I called again today they hadn’t even bothered to tell me they’d had to re-order the part they replaced for me in 2017.

    So you can see why people go elsewhere for their repair options!

    I've had really poor experiences with third party repairs. I just about always end up with an issue. I wouldn't do it again. I would just bite the bullet and pay Apple.

    Cars don’t store your fingerprints or Face ID data.
    Certain parts must be matched for security.

    On the other hand, Apple seems to go overboard and they will need to explain why.

    It’s a feature. Not a bug.
    The new feature is that your phone has one less feature. ;)

    I would never used an unauthorized 3rd party repair service. Seems like asking for trouble.

    One of iPhone's biggest selling points is the screen. An unauthorized repair costs ~$50-$70 and results in questionable sensitivity, color, brightness, pixel pitch and energy consumption (now add light sensor to the mix). For $129, Apple replaces the screen for you, and reseals the phone for waterproofing.

    I think this is the time when it's well worth it to pony up the extra $$. I just broke my screen last summer, and the replacement worked perfectly ever since.

    No cars contain parts that protect your actual life not your digital one.

    Anyone who uses a local garage to repair their car shouldn’t really have an issue getting a 3rd party phone repair.

    I believe the message is crystal clear: you'll deal only with Apple and their monopolistic pricing.

    As this type of thing has happened before, affecting even authorized Apple service providers, it is no accident and by design. Apple wants particularly iPhone customers entirely within their walls with no outside recourse.

    Thus, buyer beware; by purchasing the product you are effectively agreeing to such terms for the life of the product, as Apple dictate same. They are not your friend in this, but a vendor imposing such terms, if covertly.

    TIL unauthorized tinkering with my premium device can cause unintended and undesirable consequences.

    Pretty sneaky Apple trying to corner the repair market now but as the previous poster said even a certified repair still damaged their phone .

    His point seemed pretty clear to me. Guess some people do need everything spelled out for them.
