Going to a third-party vendor for iPhone screen replacements (or doing the repair yourself) may seem like a great idea. But it’s probably not.
Despite the fact that it’s probably cheaper, getting your iPhone’s screen replaced by a third-party might damage your handset if it’s not done properly. But even if it is, there are a handful of things that can go wrong when you get a screen replaced by anyone other than Apple. Note: Not all repairs by third-party shops go awry. The following examples provide insight into problems that can occur.
After being updated to the latest iOS 11.3 software version, thousands of iPhone 8 devices have shown signs of defunct screen/touch functionality, according to repair technicians across the country.
According to 9to5Mac, "It looks like Apple is using a custom microchip that pairs with the display. Once a third-party repairs a screen, they must also upgrade the microchip, otherwise iOS will reject all touch input from the device."
It's possible that Apple could rectify this problem with a software update, but at the time of writing, no remedy has been issued.
Using a display glass that’s not an official Apple component can throw your iPhone’s tint off. Whether that’s because the glass is of subpar quality or just a slightly different glass composition, or an off-brand backlight, it’s still an annoying aftereffect of cheap third-party screen replacements.
According to some iPhone users who had their screens replaced by a third-party, some folders can appear colder and darker than normal. On the other end of the spectrum, other colors can look unnaturally warm by comparison. Sure, you may get used to it in time, but it’s still a negative worth mentioning.
Apple designs its products very carefully, and because of that, the hardware and software in an iPhone are specifically optimized in a certain way. Getting your screen replaced by someone other than Apple can throw all of that off.
Using a non-Apple screen has been known to affect the overall responsiveness of your display — from typing on a keyboard or using 3D Touch. Some users who got a third-party repair even report “dead zones” where touches aren’t registered.
If you own an iPhone and a pair of polarized sunglasses, you can probably attest to the fact that the latter can affect how you see the former. Because of the nature of LCD-based displays, an iPhone’s display might look a bit wonky at certain viewing angles when viewed through a polarized lens.
But this problem can get much worse if you get your screen replaced by a third party — possibly due to substandard components or improperly performed repairs.
According to some Apple users, the screen can be impacted by severe glare or even go completely blank at specific angles.
