Apple has introduced a feature in iOS 14.4 added, which displays a warning message if the iPhone camera was not repaired with original parts. Now Apple has published a support document.
Starting with iOS 14.4, the iPhone will recognize whether the camera has been repaired using genuine parts. If this is not the case, the user will receive a warning. Accompanying this warning, Apple has provided a support document that highlights the importance of having an iPhone repaired by a trained technician using genuine Apple parts. It also lists what can happen if non-Apple components are used.
iPhone cameras are designed, tested, and manufactured to Apple's quality and performance standards, including intuitive and responsive autofocus, Portrait mode with enhanced bokeh and depth control, and Portrait Lighting effects.
iPhone Camera: Proper Safety and Repair Procedures
The company then goes on to explain why certified technicians should carry out repairs. is called it in it:
Only technicians who have completed Apple service training and use genuine Apple parts and tools should replace iPhone cameras. These service providers include: Apple, Apple Authorized Service Providers, or independent repair providers using genuine Apple parts. Replacements performed by anyone other than Apple Authorized Service Providers or certified technicians may not follow correct safety and repair procedures and may result in improper function or issues with image quality or overall device safety. Apple camera parts are designed to fit snugly into the device. Additionally, repairs that do not properly replace screws or panels may leave loose parts that could damage the battery, cause overheating, or result in injury.

iPhone camera repair: Apple lists possible consequences
Accordingly, a non-original camera component can lead to compatibility or performance issues. Apple warns of several possible things that can go wrong.
If a service provider uses non-genuine camera parts, the following may also occur:
– The camera does not focus properly or the images are not sharp.
– When using Portrait mode, the subject may not be in focus or may only be partially in focus.
– A third-party app that uses the camera may freeze or quit unexpectedly.
– Real-time preview in third-party apps may appear blank or get stuck
This warning message was implemented with iOS 14.4. However, it does not apply to all devices, as Apple points out. This means that the warning message is currently only displayed on the iPhone 12 mini, iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max. If a repair is carried out using non-original parts, users will see a warning in the settings, in the "General" section under "About". This is displayed for around 15 days. In addition, the warning is also displayed on the lock screen. According to Apple, the display remains visible for four days. (Photo by ADCstock / Bigstockphoto)
