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.
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.
