IPhone 11 new issues
Looks like Apple have a problem related to the newest technology. Users of the new iPhone are complaining that after the iOS updates and iOS 13.1.3 13.2 beta 3 they were Ultra Wideband error Update Failed.
In particular, it does not allow to send files through AirDrop, as it refers to the latest chip U1, which is responsible for the new Apple smartphones in the format of ultra-wideband communications (UWB).
While the cause of the problem not determined, but Apple changes these smartphones under warranty. While some users managed to solve the issue yourself by restoring the firmware from a backup. But for some reason this method does not work at all, and some regularity has not yet been found.
