New iPhone update brings unexpected problems for users - important functions down. Apple has not yet responded to IPPEN.MEDIA’s request as to whether this means that all functions will work correctly again.
iOS 17.4 appears to disable the iPhone's internal barometer, which has been present in every Apple phone model since the iPhone 6. Apps that access information from air pressure and altitude measurements are therefore affected by the error. The operator of the Flyskyhy app, which is used for sports such as paragliding, even warned against installing iOS17.4.
