Apple has released the third beta of iOS 13.3.1 and iPadOS 13.3.1 to developers and public beta testers
What’s new in iOS 13.3.1
Networking & Wireless location
After some concerns that the new Ultra-wideband wireless chip allowed for tracking users’ location, Apple has added a switch to disable location tracking for networking and wireless functions. Go to Settings > Privacy > Location Services > System Services to find it.
Screen Time communication limits fix
A new feature in iOS 13.3, communication limits, allowed parents to control to whom their children can talk, and when. A workaround allowed people to text an unknown number to a child’s phone, which they could add to Contacts, and then communicate with more freely. We don’t yet have confirmation, but we expect iOS 13.3.1 will close this loophole.
Bug fixes
Users have encountered quite a few bugs in iOS 13.3. Some have encountered an issue with re-connecting to cellular networks when Wi-Fi doesn’t work, speakerphone and FaceTime echo, problems with the Mail app, and more. We expect many of these to be fixed in iOS 13.3.1.
