It's time for another iOS beta update.
iOS 13.3.1 beta 3 and iPadOS 13.3.1 beta 3 have been released by Apple. These updates are currently available to registered developers. If that's you, then you can get the update over the air by going into Settings > General > Software Update on your device.
You can also update by going to Apple's Developer Center on the web.
The update to iOS 13.3.1 includes a new toggle in the "Networking & Wireless" section of the Settings app that'll disable the U1 Ultra Wideband chip in the iPhone 11 and 11 Pro. Doing so will also disable Wi-Fi and Bluetooth.
Apple is including this new toggle in response to the recent discovery that the iPhone 11 and 11 Pro access a user's location even when Location Services is disabled. This is because the U1 Ultra Wideband tech is subject to international regulatory requirements and must be disabled in some locations, and so the phone must check to see if it's in one of these locations.
Also rolling out today is watchOS 6.1.2 beta 3 for the Apple Watch. There haven't been any major new features or changes discovered in this update, but it likely includes some under-the-hood bug fixes and performance improvements.
