Locking the touch screen on an iPad prevents unintended input or changes to the device’s settings or apps. It is a crucial security measure, especially when the iPad is in public spaces or shared with others.
To lock the touch screen on an iPad, simply press the Sleep/Wake button located on the top right or top of the device, depending on the model. This button also serves to turn the iPad’s display on or off. When the Sleep/Wake button is pressed, the screen will go dark and the device will enter sleep mode. The touch screen will be disabled until the Sleep/Wake button is pressed again or the iPad is woken up using another method, such as Touch ID or a passcode.
