iOS 12 developer beta 4 starts rolling out

iPhone iPad iOS 12

Apple has released the iOS 12 developer beta 4 to all eligible devices. It should reach wider availability as the iOS 12 public beta 3 within the next few days.

According to GSMArena, this version of iOS 12 has something a bit different in store for the widely publicized USB Restricted Mode. The tool came out officially with iOS 11.4.1 just a few weeks ago. It basically shuts down the Lightning port on an iPhone after an hour has passed since the handset was unlocked.

The restriction allows the Lightning port to only charge the iPhone and stop any kind of communication with an external device. The move severely restricts the efficiency of hacking machines like GrayKey which need time to crack open iPhones. However, a security researcher soon discovered a loophole which successfully managed to trick the feature temporarily.

It seems Apple has decided to make things even more secure in iOS 12. USB Restricted Mode is apparently going to stop waiting for an hour and just demand a password the moment a computer, hacking device, or USB accessory is plugged in.

This would put an end to police or thieves having at least an hour to open up an iPhone. The process becomes a bit more annoying for users though, since they’ll have to punch in their passcode every time an external device is connected to their iPhone. Still, that’s a small price to pay for security. Plus, people will be able to disable it by going into Settings > Touch ID & Passcode.

iOS developer beta 4 also has some other nifty changes. Apple’s animated activity stickers are now available in Messages, no Special Challenges required. iCloud photo uploads now takes battery into consideration and automatically pauses if there’s too much drainage. Memojis now have metallic earring colors and lip styles.

iOS 12 should hit everyone this September. Apple will keep rolling out beta versions of it till then.
