Dolphin Browser How to lock the screen?

In the 8.4 version of the Dolphin Browser, if you turn on the phone's screen to rotate automatically, a lovely lock button appears on the Dolphin screen at the time of the turn, and you can lock or unlock the screen by clicking the button, as shown in the following figure: The left image is unlocked, and the screen can rotate automatically; the right is locked. In this state, the interface does not rotate automatically, but it remains in the state when the screen is locked.
