Dim Screen, brightness adjustment maxed out

Hello all, I'm working on a Samsung Tab 4, wifi only with screen brightness issues, specifically, the screen image can not be seen unless in a dimly lighted area, when in sunlight the screen is dark - even if I shade the screen with my hands, the screen image cannot be seen. The brightness control is turned all the way up.

When the image can be seen, the brightness is consistent , no dead pixels and the image is clear(not blurry). Any ideas on what I can do to increase the brightness?

@meepfish1 has a relevant suggestion. Other than that, what is the history of the device? Has it ever had a screen replace or other work done? Its possible there is an issue with the LCD or with the board itself, in regards to the backlight circuit. This is usually the case when work has been performed, the device has been damaged in some way, been near water, ect

ere are some things you can try to increase the brightness of your Samsung Tab 4 screen:

  1. Check the brightness settings. Make sure that the brightness is turned all the way up. You can do this by swiping down from the top of the screen to open the notification panel. Then, tap on the brightness icon and drag the slider to the maximum brightness level.
  2. Turn off adaptive brightness. Adaptive brightness is a feature that automatically adjusts the brightness of your screen based on the ambient light. This can be helpful in some cases, but it can also cause the screen to be too dim in bright sunlight. To turn off adaptive brightness, go to Settings > Display > Advanced > Adaptive brightness and turn off the switch.
  3. Update your tablet's firmware. Samsung regularly releases firmware updates for its tablets that can fix bugs and improve performance. To check for a firmware update, go to Settings > System > Advanced > Software update and tap on "Check for updates."
  4. Reset your tablet. Resetting your tablet can sometimes fix software problems that are causing the screen to be dim. To reset your tablet, go to Settings > General management > Reset > Factory data reset and tap on "Reset."
  5. Take your tablet to a repair shop. If you have tried all of the above steps and your tablet's screen is still dim, you may need to take it to a repair shop. There may be a problem with the hardware of your tablet that is causing the dim screen.
