On Monday, Apple released the first major update to iOS7 -- iOS7.1 -- in an attempt to fix many of the bugs plaguing the operating system. 

The update should fix the random reboot problems of the iPhone 5s, iPad Mini with Retina Display and iPad Air. Many users complained of a home screen reset, and this should now be resolved.  

Apple has also made adjustments to improve the operating system on older devices like the iPhone 4, iPad 2 and third generation iPad. These fixes address some of the most common complaints -- including improving speed on the iPhone 4. 

Many of the changes are subtle, but they are very handy. 

The update improves the accuracy of the fingerprint sensor on iPhone 5S devices, which some users had issues with. The sensor now has an easier time recognizing fingerprints.

Another minor upgrade includes an additional way to activate Siri. You can now hold down the Home button and start speaking, letting go when you're done with your command. Male and female Siri voices have also been upgraded to sound more natural in a few different languages including Mandarin, Japanese and UK and Australian English.

iTunes Radio, the Calendar App and FaceTime have all added minor improvements.

You'll also notice that the keyboard has been slightly altered and is now clearer. And you'll see a slight alteration in the color scheme of some apps. 

One of the biggest upgrades is CarPlay. CarPlay lets drivers control features such as navigation, the phone feature, music and messages using Siri voice control, an in-car touchscreen display, and buttons built into cars.

But it's not available for everyone. CarPlay can only be found in Volvo, Ferrari, Honda, Hyundai and Mercedes-Benz, and will only be available for a small number of new vehicles for now.

The free update is available now and can be downloaded by going to "software update" in the "general" section of the Settings app. Make sure you're connected to Wi-Fi, the update is too large to download over a cellular network.
