How do I adjust the screen brightness on my Galaxy J3 Prime (SM-J327W)?
Ever open your phone in the middle of the night and was blinded by the brightness of your screen? Have your phone automatically adjust the brightness of the screen, depending on the darkness of your surrounding environment. You can also adjust your screen settings with various screen options available. Lowering brightness helps conserve battery life.
Note: Screens and settings available may vary depending on your Canadian wireless service provider and your software version.
