1. iOS 11 Control Centre tips
Add new controls: Unlike previous versions of iOS, you can now add and remove controls from Control Centre. Head to Settings > Control Centre > Customise Controls and then choose which controls you’d like to add.
Reorganise controls: To change the order of those controls you’ve added, tap and hold the three-bar menu on the right of whichever control you’d like to move, then move it up and down the list to wherever you’d like it to be.
Expand controls: Some controls can become full screen, just force press (i.e. press harder on compatible screens) on the control you want to expand and it’ll fill the screen.
Switch on personal hotspot: By default, the connectivity control only has four options in it. If you force press to expand it, you’ll get a full screen control with two more options. Tap on the personal hotspot icon to switch it on.
Switch on Night Shift: To switch on Night Shift – which kills blue light, making it the screen warmer – force press the screen brightness control, then tap the Night Shift icon at the bottom of the screen.
Activate screen recording: One of the new options you can add to Control Centre is Screen Recording. Make sure you add the control, then open Control Centre and press the icon that looks like a solid white circle inside a thin white ring. From now on it’ll record everything that happens on your screen. Press the control again when you’re done, and it’ll save a video to your Photos app automatically.
Adjust flagshlight/torch brightness: You can switch on your camera flash, using it as a torch, by opening Control Centre and tapping on the torch icon. If you want to adjust the brightness, force press the icon, then adjust the full-screen slider that appears.
Quickly switch where audio is played: One cool feature is the ability to change where music is playing. While music is playing, through Apple Music, Spotify, or wherever, force press on the music control or just tap the little icon in the top corner of the music control. This brings up a pop-up showing available devices that you can play through. This could be connected earphones, Apple TV, your iPhone or any AirPlay device.
Set a quick timer: Instead of heading to the timer app, you can force press on the timer icon, then slide up or down on the full-screen to set a timer anywhere from one minute to two hours long.
How to access HomeKit devices: Swipe from the bottom of the screen up to reveal Control Center and then tap on the little icon that looks like a house.
