Apple's iOS 7.1 is now available for capable iPhones and iPad devices and it delivers all-new features such as teaching Siri to work with out, automatic HDR mode and new visibility options.

Compiled by BGR and CNET, here are five new features Apple included on the latest iOS 7.1 for iPhone, iPad and iPod Touch devices capable of running iOS 7.0.

Enabling HDR Auto

In iOS 7.0, HDR resets each time the camera app is closed but Apple fixed that bug introduced HDR Auto mode on iOS 7.1 for iPhone 5S.

Go to the camera app > Tap on the HDR on or HDR off located at the top screen of the camera > Select HDR Auto. The camera app will save the settings for automatic HDR capture.

Cooperative Siri

Having relationship for Siri can be very difficult from previous iOS versions but in iOS 7 you make Siri work for you instead of the other way around. You can make Siri male or female and even change language to non-English ones such as Chinese, French, German, Italian, Japanese and Korean.

Go to Settings > General > Siri > Language option > Select language > Go back > Voice gender.

For head motion controls, go to Settings > General > Accessibility > Physical and motor > Switch Control > Switches > Add new switch > Source screen > Camera > Left head movement > Action screen > Siri option.

It will now recognise your head motion moving to the left and pop-up right on the screen for your command.

Do not forget that Siri also support different accents including Australian English, Canadian English, U.S. English and UK English.

Visibility Options

Display contrast in iOS 7.1 included some tweaks for fine-tuning the screen of your iPhone, iPad or iPod Touch.

Go to Settings > General > Accessibility > Increase contrast. Reduce transparency, Darken colours and Reduce white point are all separate options you can modify.

Disable Parallax

Apple now enables the disabling of parallax wallpaper effect while keeping the zooming transition animations for apps you open or close.

Go to Settings > General > Accessibility > Disable Reduce Motion > Go back to Settings > Wallpapers and brightness > Lock screen wallpaper > Turn off Perspective Zoom.

Enable Buttons

All iOS version 7 features minimalistic design and UI which complained by many users worldwide but in version 7.1, you can add button shapes for text-only tap targets.

Go to Settings > General > Accessibility > Button Shapes.

Switch control on Siri is not perfect yet and require some adjustments on the sensitivity to make the feature accurate.
