The power key of the mobile phone is a key that is used frequently. It is used when the phone is turned on, when it is turned off, when the screen is locked, and when the phone crashes unexpectedly. Although the lifespan of a key should not be worried when it is used normally, there are also some "obsessive-compulsive" users who want to better protect the key. As smartphone users, what special methods do we have to reduce the frequency of power key use?

This article is divided into three parts, namely, unlocking, screen locking and restart and shutdown. The methods described are all used for Android phones.
