You can tailor your iPhone to your own interests and preferences. Personalize your Lock Screen, customize the appearance of apps on your Home Screen, keep your favorite features like magnifier and remote handy, change the sounds and vibrations for calls and messages, and more.
Many iPhone features—like the timer and flashlight—are just a swipe away in Control Center. To quickly open Control Center on an iPhone with Face ID, swipe down from the top-right edge; on an iPhone with a Home button, swipe up from the bottom of the screen.
To customize the controls, open Control Center, then touch and hold the background of the screen. Tap Add a Control at the bottom of the screen, then swipe up to view the controls gallery. When you see a control you want to add, tap it.
iPhone can play different sounds and vibrations for phone calls, text messages, calendar alerts, and other notifications.
