Apple released its latest mobile operating system update on Monday , iOS 7.1 . The major upgrade packs in an assortment of bug fixes , improvements , new features and some subtle changes to the overall interface . iOS 7.1 is the first major update to the iPhone , iPad and iPod Touch operating system since iOS 7 was released in September 2013 . There are some welcome repairs in 7.1 . The update improves the accuracy of the fingerprint sensor on iPhone 5S devices , which occasionally had issues recognizing fingerprints . Apple says there are general performance improvements for iPhone 4 owners , many of whom complained of speed and other issues after upgrading to iOS 7.0 . It also repairs a bug that caused the home screen to crash . Minor upgrades include an additional way to activate Siri . You can now hold down the Home button and start speaking , letting go when you 're done bossing it around . Without the upgrade , you must wait for Siri to detect when you are done speaking . Male and female Siri voices have been updated to sound more natural in Mandarin , Japanese and UK and Australian English . iPhone photographers wo n't have to manually toggle on HDR . The camera on the iPhone 5S will now automatically detect scenes it thinks can benefit from high-dynamic range and turn it on . iTunes Radio , the Calendar App and FaceTime have all added minor improvements , and there are a handful of accessibility tweaks aimed at making the OS work better for the visually impaired . The big new feature in 7.1 is CarPlay , a tool for pairing an iPhone 5 and newer smartphones with select in-car systems . Apple announced details about CarPlay last week . It lets drivers control features like navigation , the phone , music and messages using Siri voice control , an in-car touchscreen display , and the usual buttons and knobs built into cars . Do n't get too excited about taking CarPlay for a spin just yet . The feature is part of a new partnership with big-name car companies , including Volvo , Ferrari , Honda , Hyundai and Mercedes-Benz , and will only be available for a small number of new vehicles for now . To get the free update on your mobile Apple device , make sure you 're connected to a Wi-Fi network ( it 's too big to download over your cellular connection ) , go to Settings - > General - > Software Update and tap Download and Install .
