A swipe down from the top of the screen reveals your notifications, just as it has for some time now. However, a new Cover Sheet has replaced the Notification Center of old. 

It's confusing, mainly because it looks just like your lock screen, but it's not the lock screen. And on top of that, only a couple of notifications are displayed unless you swipe up to view older alerts. It's weird and will take some getting used to. 

Apple is doing its part to eliminate distracted driving. Your iPhone can now detect when you're in a moving vehicle and can, if you want it to, automatically enable Do Not Disturb While Driving. 

There are times when the best way to explain something is to draw a picture. When composing an email, long-press and then select Insert Drawing from the pop-up. Draw, sketch or play tic-tac-toe and send it on its way. 

With iOS 11, Apple is finally moving the volume control that used to take over the screen when you were watching a video. Instead of showing a giant, annoying volume graphic, Apple tucked the volume indicator into a corner of the screen. Woo! 

Apple is once again trying its hand at a social-oriented service with Apple Music profiles. The first time you launch Apple Music after updating to iOS 11, the app walks you through setting up your profile and privacy settings. In the future, you can find your profile and the same settings in the For You tab with a tap on your profile icon. 

Instead of your trying to capture a precious moment during a FaceTime call by taking a screenshot, iOS 11 will let you take a Live Photo of the call. The toggle is in Settings > FaceTime. 

Tap the new shutter button while on a FaceTime call to take a FaceTime Live Photo. Pretty sweet, right? 

The Apple Watch is no longer the only Apple device with an Emergency SOS mode. Your iPhone can now call local authorities and contacts of your choosing if you simply press the power button five times. 

Depending on your preferences, which you can set in Settings > Emergency SOS, your phone will either prompt you to complete the call or will do it automatically. 

You can now add a shortcut to the Notes app in iOS 11's revamped Control Center, and access the Notes from the lock screen. 

Hidden in Settings > Notes is an option to set the amount of time you want to go by while you can still access the last note you were in. 

It's a small change, but the look of Apple's Handoff feature to open apps and web pages from a nearby Apple device has been slightly tweaked. 

A new sharing option has been added to iOS 11. It's called Markup as PDF and it lets you do just what it says. 

When viewing a web page, a photo or a file, tap the Share icon and select Markup as PDF, and iOS will convert it to a PDF. 

You can then use the iOS markup tool to draw, sign or add text to the document before saving or sharing it. 

A new Accessibility feature does away with the need to talk to Siri. Instead, you can type to Apple's digital assistant. 

Open Settings > General > Accessibility > Siri and toggle Type to Siri to the On position. 

Now, whenever you hold the home button to activate Siri a keyboard will pop up for use. 

If your power button breaks, you can still turn the phone off with a new Shut Down option in Settings > General. Although, it's not clear how you will actually turn the phone back on if that is the case. But the option is there. 

Apple is using a new photo and video file format starting with iOS 11, but if you'd rather not mess with it or are running into compatibility issues, you can revert back to the older format. 

Open Settings > Camera > Formats to set your own preference. 

You can now decide whether you want apps to refresh in the background based on your device's connection type. 

Open Settings > General > Background App Refresh > Background App Refresh and select from Off, Wi-Fi, or Wi-Fi & Cellular Data. 

The iPad's new app dock has a section that displays recently used apps, but if you're not a fan of the constant suggestions you can disable it. 

Open Settings > General > Multitasking and turn Show Recents Off. 

Apple has added a one-handed keyboard option to the iPhone. There are two ways to activate it:

• Settings > General > Keyboards > One Handed Keyboard 
• Long-press on the emoji or globe icon on the keyboard

You can select a right- or left-handed keyboard, and switch back to a full keyboard following the same steps outlined above. 

Instead of having to go through each and every app's notification settings to set your privacy preference, iOS 11 now has a universal setting for message previews. 

Go to Settings > Notifications > Show Previews. There you can select the default setting for all apps.
