The last update that we saw from Apple was a month ago and included the much-needed feature like support for Messages in iCloud and AirPlay 2. To keep up with all the updates, Apple released the next iOS update, 11.4.1. This is the fifteenth update to the iOS 11 operating system.According to Apple&#39;s release notes, the new update mainly focuses on bug fixes and is intended to upgrade the security of the iPhone and iPad. The release stated:Fixes an issue that prevented some users from viewing the last known location of their AirPods in Find My iPhoneImproves reliability of syncing mail, contacts, and notes with Exchange accountsOne significant fix is related to the bug that prevented users from viewing the last known location of their AirPods in Find My iPhone. The iOS 11.4.1 update will also enhance the reliability of syncing contacts, mails, and notes with Exchange accounts.The brightest spot over this update is the inclusion of USB Restricted Mode, which we first saw in the iOS 12 beta version. The tech giant may found it more sensible to release this feature without waiting for the iOS 12 program that is still a couple of months away. The aim of introducing the USB Restricted Mode is to prevent the law enforcement and other tech agencies from gaining access to the iOS device.The update may have brought a sigh of relief for the Apple users, but it may lead to a fierce backlash from the government agencies like CIA and FBI, who had earlier futilely persuaded Apple to unlock its devices of convicts charged under terror activities.&ldquo;We&rsquo;re constantly strengthening the security protections in every Apple product to help customers defend against hackers, identity thieves, and intrusions into their personal data,&rdquo; Apple said in a statement. &ldquo;We have the greatest respect for law enforcement, and we don&rsquo;t design our security improvements to frustrate their efforts to do their jobs.&rdquo;Read: Apple Imitates Chinese Clothing Brand Logo, Gets SuedAfter updating to iOS 11.4.1, USB Restricted Mode will be enabled by default and further can be played with from the Settings option.Earlier, it was possible to get into the iOS devices by using USB connection and cracking the passcode through Lightning connector. Now, the USB Restricted Mode cuts this down by disabling data access to the Lightning port after an hour of device unlocking.It looks like the Apple is done with all the iOS 11 updates and the next big thing from the Cupertino based company will be iOS 12 that promises to bring next-generation changes like Group FaceTime, Screen Time, Memoji, and much more.Read: All About iOS 11 And iOS 12 FeaturesiOS 11.4.1 is available over-the-air on all the compatible devices that include the iPhone 5s and above till iPhone X, the iPad Air and later, the iPad mini 2 and later, and the 6th-generation iPod touch.
