1/ Scan QR codes in iOS 11 — Apple has added QR support to iOS 11 so you can scan QR codes directly in the Camera app, without the need for a third-party app as previously:
Open the Camera app and make sure the rear facing camera is enabled.
Point the camera viewfinder at the QR code. Make sure the code is entirely visible in the view finder.
Hold the camera steady. The QR code will be scanned instantly and you’ll see a notification at the top of the iPhone or iPad screen describing what kind of QR code you’ve scanned (website QR Code, Calendar QR code, etc).|
You’ll see what action the QR code can perform (add event to your calendar, open page in Safari). You don’t have to to press the capture or shutter button. Just pointing the camera and holding it steady at the QR code is all you need to do.
2/ Stop apps from asking for reviews in iOS 11 — If you dislike the pop-up windows from apps constantly asking you to leave a review in iOS 11, you put an end to it.
Go to the Settings app.
Tap on iTunes, then App Store.
Turn the In-App Ratings & Review option off. Phew!
3/ Add the Magnifier to Control Center — The iOS Magnifier feature is a way to use your device as kind of a low-powered set of binoculars or a magnifying glass. It has been around since iOS 10 – a triple-click of the Home button boots it up if you have turned the feature on in Settings. In iOS 11, tough, you can now add an icon for it into Control Center.
First, visit the Settings app and look for the Control Center section.
Tap that, then Customize Controls. Scroll down and touch the plus button next to Magnifier and it’ll appear at the top of your list under the Include section.
You can also drag any of the three-lined icons shown to the right of the tools above to set the order in which you want them to appear in Control Center. The next time you bring up Control Center by swiping up from the bottom of your Home Screen, you’ll see your new addition.
4/ Change Key Frames in Live Photos — One of the newest features in iOS 11 is the ability to change the key frames in Live Photos [a gimmick I’ve never got, but if you use it …]. The key frame is what appears in Photos to show what the sequence is, and it’s typically chosen automatically when you snap the picture.
Tap on the Live Photo you want to change, then, tap Edit in the top right corner. You’ll see a slider at the bottom of the photo with all of the frames available within the Live Photo. To change the key frames in Live Photos, you move the selector of that slider back and forth until you find the frame you like.
Once you’ve found the frame you prefer, tap on Make Key Photo to set the key frame of the Live Photo to the frame you like best.
5/ Teach Siri to correctly pronounce names on your iPhone — Asking Siri to text or call contacts is one of the virtual assistant’s basic functions, but some names can be hard for the system to understand and pronounce. AppleInsider shows you how to ensure correct pronunciation, and contact retrieval, in this video. [This also works in iOS 10.]
