iOS 12 beta 4: Users must unlock device before connecting any USB accessories
Apple is continuously improving the iOS 12 system to make the iPhone’s Lightning interface more secure. The reason for this is that Apple added extra security to this interface in iOS 12 beta four released this morning. The USB Restriction mode on the latest beta version of iOS 12, which disables the device’s Lightning interface after the last time the iOS device has been unlocked for more than an hour. This Lightning interface can still be used for charging, but all accessories are not available until the device is unlocked.
In the fourth developer beta of iOS 12, whenever you connect your computer or USB accessory to your iOS device, you’ll need to enter your password. Before making changes, law enforcement agencies or criminals have an hour to crack iOS devices, and now, forcing cracking iOS devices will become more difficult.
In the iOS 11.4.1 system released last week, users can manually enable the USB limit mode by pressing the side button five times, and in the latest iOS 12 beta 4, such operations are no longer needed.
Apple has made it clear that their participation in this security measure is not only to make the cracking of law enforcement agencies more difficult but to prohibit anyone from accessing mobile phones that are not their own, after all, any security holes that law enforcement can exploit can be easily exploited by criminals.
