Setting a picture as your mobile wallpaper is a simple process. First, open your phone’s gallery and select the picture you want to use. Then, tap the options button (usually represented by three dots or lines) and select "Set as Wallpaper." Some phones may also provide the option to adjust the image’s size or position. After selecting the screen (home screen, lock screen, or both), confirm your selection, and the picture will be applied as your new wallpaper. Enjoy your personalized mobile screen!
