Why does my Galaxy A24 display have black bars and How to fix it?

Black bars on a Samsung Galaxy A24 display are the black borders that appear on the top and/or bottom of the screen when viewing content with a different aspect ratio than the display. For example, if you are watching a 16:9 video on a 21:9 display, you will see black bars on the top and bottom of the screen because the video is not wide enough to fill the entire display.

Common Causes of Black Bars on Galaxy A24 Display

Black bars on your Galaxy A24 display can be caused by a variety of factors, including:

• Incompatible aspect ratio: The aspect ratio of the video or image you are viewing is not compatible with the aspect ratio of your display.
• Incorrect screen zoom settings: Your screen zoom settings may be set too high, causing the edges of the display to be cropped.
• Hardware issue: If you have tried all of the troubleshooting steps below and your Galaxy A24 display still has black bars, it is possible that there is a hardware issue with your device.

Potential Solutions to the Galaxy A24 Black Bars on Display

Here are some tips on how to fix black bars on your Galaxy A24 display:

• To check the aspect ratio of a video or image, open it in a photo or video viewer app and tap on the information icon.

2. Adjust your screen zoom settings

If your screen zoom settings are set too high, the edges of the display may be cropped. 

• To adjust your screen zoom settings, open the Settings app and go to Display > Screen zoom. Drag the slider to the desired zoom level.

If you have tried all of the above steps and your Galaxy A24 display still has black bars, you may need to reset your device to factory settings. This will erase all of your data and settings, so be sure to back up everything important before you proceed.
