How does Xiaomi mobile phone go back to the previous step?

1. If the mobile phone has a navigation key (such as Xiaomi 8), click the navigation key at the lower left of the mobile phone to return.

2. If the mobile phone does not have navigation keys, but supports full-screen gestures: touch and stay at the bottom of the screen, and a virtual navigation key will appear by sliding from the edge to the left. Click the corresponding button to return. Long press the task key to open the background management, and click the leftmost home key to return to the desktop.

3. If the phone doesn't have navigation keys or doesn't support full-screen gestures, you can try sliding the bottom of the screen. After the virtual navigation bar appears, touch the Home button again to return.
