Earlier this month, Apple had seen fit to release the second beta of iOS 13.3.1. It has now been discovered that it includes a toggle to disable the Ultra Wideband chip in the device. The new toggle can be found in the Settings app if you're running the latest beta of iOS 13.3.1.  Let's dive in to see some more details on the build and how you can disable the Ultra Wideband chip in your iPhone.

It was also discovered last month that the iPhone 11 and iPhone 11 Pro were requesting location data in the background despite the location services being turned off. Apple stated that it was due to the new UltraWideband chip in the flagships.
