It is not something new, which Apple tends to vehemently watch over the legitimate use of components for its iPhone. At the moment, developers and some users are testing the second beta of iOS 14, a version in which a new alert has been discovered that will jump on many devices, which could catch many users by surprise.

Everything is related to the use of original replacement parts in iPhones. Apple wants the user to have all the information regarding unauthorized changes or made using non-original parts. In this sense, MacRumors has detected a new message in the iOS 14.4 code, which reads: “It cannot be verified that this iPhone has an original Apple camera.” Everything indicates that this message will appear soon on many iPhones, although it is not clear in what way.
Does it affect performance?
This warning will not affect the ability to use the camera, as it is estimated to be a similar warning to that displayed for non-original batteries, which only disables the information regarding the maximum remaining capacity. However, it is likely that users who receive this message , may also be redirected to an Apple document that explains in more detail the importance of having iPhone repairs performed by authorized technicians using original Apple parts.

It was last year when the iFixit repair website detected that Apple authorized technicians must run a special cloud-based application to complete camera and screen-related repairs on all iPhones 12. If not thus, some problems may arise after a while, according to the tests carried out by the website itself.
On the second hand market
Beyond the pressure that Apple exerts, so that iPhone users do not get out of official repair channels, the message can be useful for many users. An owner knows perfectly what he is doing with his mobile, but the measure provides some security when it is repaired, to be sure that the parts replaced are those promised. Even when many have a second-hand iPhone, bought for a long time, they could find this message when updating and get the odd scare.
Similarly, a second-hand iPhone buyer could know if it has been repaired with these messages, even if the seller indicates that “it has never had a hit or failure.” Similarly, it can be a bit of a drag for refurbished sellers, where almost all second-hand iPhones are repaired with aftermarket parts.
