If the power switch of the iPhone and iPad is broken or damaged, it is still possible for the user to lock the device. You can solve the problem by using the Assistive Touch feature. Assistive Touch allows you to simulate physical movements and select buttons with simple options.

 How To Lock The iPhone Touch Screen And Display A Locked And Fixed App

In iOS, there is a feature called  Guided Access that allows you to use a specific application for a desired period of time, and give the phone to friends or children. In fact, Guided Access is a great way to protect your privacy while sharing. For example, you can run the Contacts app and give the phone to someone else to write down the information of a specific contact, and after a minute, the phone will be automatically locked and unused.

Another use for Guided Access is to select a part of an app and display it on the screen locked and fixed. In other words, the touch screen fails and you can safely give the phone to others to see what is in the selected area. There is no ability to run other apps, as well as the ability to work with the opened app and refer to other sections and pages.
