All The Key Features Of iOS 7 Due September 18th 2013
We take a look at the key features of iOS 7 that is due for release on the 18th of September and will be available to the public as a world wide download.
iOS 7 will be available for iPhone and iPad and will feature many new improvements including live wallpapers and a fully upgraded user interface.
Tim cook has just announced this at the live keynote in California in-front of a stunned audience with the iPhone 5S and 5C both being released with the new platform and iPad support coming on the 18th September.
Generally speaking, iOS 7 now gives more room for apps, taking every edge-to-edge. Using all of the screen space really makes a difference. All of the icons have been redesigned, too, giving them a cleaner appearance.
Finally, the other change on the home screen is that the signal strength bar has been replaced by a series of dots, rather than bars.
It’s perhaps a shame that less has been done to bring more information to the home screen, such as with Android’s widgets, but Apple is presenting information in a different way. Here’s what you can expect from the new OS:
Notification Centre: The Notification Centre is still on top but it’s much less clunky than in the previous versions of iOS. And yes, the centre will give details about new mail, missed calls, etc. It also has a new feature called Today which will give you a summary of everything you have lined up for the day. Users can also access the Notification Center from any screen, including the Lock screen.
Control Panel: There’s now a control panel at the bottom and users can just slide upwards to access the settings. You can turn Airplane mode on or off, Wi-Fi, Bluetooth, and Do Not Disturb, volume settings etc, from here. This works even in Lock Screen mode. Access to the flashlight, timer, calculator, and camera is also available from the Control Panel.
Multitasking: If you have an app that you’re always using, iOS 7 will make note of that and make sure its updating in the background. So if you tend to check your favorite social app at 9:00 am every day, your feed will be ready and waiting for you.
Camera: The Camera now comes with inbuilt new features and you can edit photos as you shoot them. Filters in Camera are coming only to iPhone 5, iPod Touch 5th generation, while Filters in Photos app will be available on iPhone 4 and above, iPad (3rd generation or later), iPad mini, and iPod touch (5th generation).
Photos app: Instead of unorganized mess of photos, this will now store photos according to the time, place they were clicked. Photos will be stored in albums. You can tap years and all your shots for that year will fill the screen.
AirDrop: Apple’s answer to NFC, this will let users shares videos, email, photos, etc with their friends on iOS. You can just click on the Share button on any app that supports AirDrop, tap to share, select the person you want to share with and it will be done. AirDrop uses Wi-Fi and Bluetooth. All transfers are encrypted, so what you share is highly secure. AirDrop is available on iPhone 5, iPad (4th generation), iPad mini, and iPod touch (5th generation) and requires an iCloud account.
Siri in iOS 7 has a new voice. Also a new interface. And sound wave at the bottom.
Find My iPhone: The new feature ensures that if your phone is stolen and somebody tries to turn off Find My iPhone, they will require your Apple ID and password. Also the Apple ID and password are will be required before anyone can reactivate the phone.
