To add more home screens, you need to utilize the ‘Edit’ option on your device. Make sure you are on the home screen and press the menu key.
From the pop-up dialogue, select the ‘Edit’ or ‘Edit page’ option.
Depending on your device’s interface, you will be shown a preview of all your home screens.
From this preview, you can either delete a home screen or change their order by dragging them around.
If you wish to add another home screen, you can do that too by tapping the new screen option, usually denoted by a screen with a plus symbol on it.
Now you can simply press the back key and check to ensure you have the additional screen you wanted.
