Some iPhone 11 and iPhone 11 Pro users are reporting that after updating the software to iOS 13.1.3 and iOS 12.2 beta 3, they encountered the "Ultra Wideband Update Failed" error.
The report says the bug affects the iPhone's ability to send files via AirDrop. Obviously the problem is related to the functioning of the latest U1 chip, which provides the work of the new iPhones in the ultra-wideband format. The error does not occur en masse, but it is reported by users in various forums on the Internet. It is likely that software problems are causing this error, but so far this information has not been officially confirmed.
It is worth noting that some users managed to solve the problem on their own. The error stops appearing if you restore the previous version of the software from a backup stored in iCloud. However, this option did not help all iPhone owners who encountered a problem. When contacting an Apple branded service, such smartphones are replaced under warranty, which may indicate some kind of hardware failure. It is likely that users who cannot restore the previous version of the software will have to contact the service to replace the smartphone.
Recall that the ultra-wideband technology used to accurately determine the location of various objects appeared in the new iPhones, which were introduced this fall. Now this technology is practically useless for iPhone owners. However, in the future, developers plan to endow different devices with support for ultra-wideband technology, thereby significantly expanding the capabilities of the Find Me tool.
Official representatives of Apple have not yet voiced the possible causes of problems in the operation of the U1 chip.
