The Android 17 QPR3 Beta 2 update introduces the Lock Quick Settings connectivity feature, which requires users to unlock their devices before modifying connectivity settings such as Wi-Fi, Bluetooth, Airplane mode, and mobile data. This feature enhances security by preventing unauthorized changes to these settings without unlocking the device, providing users with more time to take necessary actions if their phone is stolen. To enable this feature, users can go to Settings, then Display & touch, Lock screen, and toggle on Lock Quick Settings connectivity.
