Recently there are reports of Galaxy S7 black screen issue. The device its self is working but the display is not. All buttons light up when pressed as they should and you can even hear notifications and phone ring. Only the screen remains black at all times.
There are a few methods that you can do to fix this issue. They all are combination of pressed buttons.
- The first one you want to try is hold down the volume down button and the power button. You should keep the buttons pressed for about 10 to 20 seconds. As soon as the display comes on with the boot logo, you let go.
- If that doesn’t work, then you should try pressing the volume up button and the power button. Some models come with different firmware depending on the production serial number. This is just to try if the volume rocker boot controls are switched. Again, you hold down the buttons until you see the boot logo.
- If the previous combinations don’t work, now you should try to pin the volume rocker (simultaneously press volume up and down), press the home button and power button. Hold those down for 20 seconds and the screen should pop back on with the boot logo.If you accidentally find yourself in the recovery menu just reboot the device.
