How do you get the back light on your phone to work?

To get the backlight on your phone to work, first ensure that the brightness setting is turned up in the display settings. You can usually find this by swiping down from the top of the screen or navigating to Settings > Display. If the backlight still isn’t working, try restarting your phone or checking for any software updates. If problems persist, it may indicate a hardware issue that requires professional repair.
