To go back to a previous screen on Android, you can follow these steps:
1. Use the back button: Android devices typically have a physical or virtual back button located at the bottom of the screen. It is represented by a left-pointing arrow or a "Back" label. Tapping this button will take you back to the previous screen or the previous app if you're on the home screen.
2. Swipe from the screen edge: Some Android devices allow you to go back by swiping from the left or right edge of the screen towards the center. This gesture is recognized by certain Android versions and can be an alternative to using the back button.
3. Use navigation gestures: On newer Android devices running Android 10 or later, you can enable navigation gestures instead of using traditional buttons. Swipe up from the bottom of the screen to go back to the previous screen.
4. Tap an on-screen back button: In certain apps, developers may include an on-screen back button within the app's user interface. This button is usually represented by an arrow pointing to the left or a "Back" label. You can tap on this button to navigate back within the app.
It's important to note that the exact method to go back can vary slightly depending on the device manufacturer, Android version, and the app you are using. These steps should serve as a general guide, but you may need to adapt them to suit your specific Android device and setup.
