Apple today seeded the third betas of upcoming iOS and iPadOS 13.3.1 updates to developers, one week after seeding the second betas and more than a month after the release of iOS 13.3 with Communication Limits for Screen Time. iOS and iPadOS 13.3.1 can be downloaded from the Apple Developer center or over the air once the proper developer profile has been installed. iOS 13.3.1 includes a “Networking & Wireless” toggle that turns off the U1 Ultra Wideband chip in the latest iPhones. The feature, located in the Privacy > Location Services section of the Settings app, turns off location for Bluetooth, Wi-Fi, and Ultra Wideband. Apple added this location toggle after it was discovered that the iPhone 11 , 11 Pro, and 11 Pro Max continue to track user location even when location services options are disabled. This is because there are international regulatory requirements that mandate the U1 chip be disabled in certain locations. The new toggle makes sure location tracking is off for the U1 chip at all times.
