If you’re like most iPhone users, you probably unlock your device’s screen each time you want to use it. But if you’re using an iPhone 12 Pro, there’s a way to keep the screen locked so that you can’t accidentally touch it or turn it off. To lock the screen on an iPhone 12 Pro, first open the Settings app and tap on General. Next, tap on Accessibility and then tap on Screen Lock. From here, you can choose to have the screen automatically lock after a set amount of time or when the device is turned off. You can also choose to require a passcode to unlock the device. If you’d rather not use a passcode, you can also manually lock the screen by pressing and holding down on the Home button for two seconds. Once locked, no one will be able to access your device unless they have your Apple ID and password or a passcode that you’ve given them. ..
