How to Lock Your iPhone Screen

You can lock your iPhone screen at any time by pressing the button on the right side of the smartphone. This button is officially referred to as the Side button.

Older iPhone models may use the Top button instead. This button is located on the top of the smartphone and performs the same functions as the Side button on newer iPhones.

How to Unlock Your iPhone Screen

To unlock your iPhone’s screen, tap the screen once and then swipe up from the bottom to the top. Depending on your security settings, your iPhone may automatically unlock after scanning your face or it may require you to input a numerical code.

Alternatively, you can also press the Side button to wake up the screen and then swipe up or use an Apple Watch to unlock your iPhone.

Why Does My iPhone Screen Turn Off During a Call?

The iPhone’s built-in sensors automatically detect when the device is close to a surface, such as your face, and will turn the screen off. This automatic process doesn’t end phone calls and is primarily done to prevent the accidental opening of apps or pressing of on-screen buttons. It can also save battery life by not powering the screen when no one can see it.

Due to this screen feature, you don’t need to manually lock your iPhone screen before or during a phone call. The iPhone screen should turn off as soon as you hold the smartphone up to your ear and will automatically turn back on when you pull the iPhone away.

If your iPhone’s screen doesn’t turn back on during a phone call, tap the screen once or press the Side button.
