Today’s problem: Galaxy Note 8 vibrates and turn on but screen stays black

I dropped my phone (Samsung Galaxy Note 8) on a Tuesday and there was a subsequent single crack running from the left top to bottom right corner. This crack is hardly noticeable. The phone continued to work without issue.

On Wednesday night I watched netflix before bed and left the phone on the charger. When I went to use it the following morning, it would not turn on. When it is plugged in, it does not show any lights to suggest it is charging. However, I do believe it has power. When I attempt to do the reboots (power button and volume) I can feel it vibrate, two short bursts followed by about a 5 second pause. This will last about a minute.

Does anyone have a suggestion? — Chris

What to do with Galaxy Note 8 that powers on but with a black screen

Screens of Samsung Galaxy devices are generally flaws free, considering hundreds of millions of them still in circulation. The current design of touch screens are reliable in general and unless they’re damaged physically, they can work as expected even years after the device’s unboxing. Your Note 8 touchscreen, just like any other touchscreen out there, is sensitive to unncessary shock from accidental drops or water exposure. We don’t know how bad the drop of your phone was but a crack, even how tiny it is, is an indicator of a serious hardware damage. In most cases, a small crack can lead to a significant crack eventually, causing the screen to fail for good.

This article will cover basic things that you can do to minimize the damage and its eventual effect on the system but you’ll still need to send the phone in if you want to have the screen work normally again permanently. We are not here to provide details on how to replace the screen on your own either. If you want to perform a do-it-yourself repair, find other sites or forums that can give you the right guide.

Clean the screen

Touchscreens may not work properly when they’re dirty, covered in grime, or when your fingers are wet or covered by gloves. Make sure that you wipe the screen with lint-free cloth, then attempt to restart it. If you’re using a screen protector, try to remove that and see if it will change anything. Basically, you want to just clean the display thoroughly before giving reboot a try.

Hard reboot your Note 8

In the event that the device may have become unresponsive, giving the impression that the screen is black, be sure to try a hard reboot. In older devices with removable battery packs, this process is done simply by pulling the battery out. Since your Note 8 has an integrated battery pack, you’ll want to perform a hardware button combination to simulate the same effect as a “battery pull.” To do that, follow these steps:

  1. Press and hold the Power and Volume Down buttons until the device powers off (approx. 10 seconds). Let your Note 8 finish the reboot for several seconds in order to pull up Maintenance Boot Mode.
  2. If successful and screen works,select Normal Boot from Maintenance Boot Mode screen. You can use the volume buttons to cycle through the available options and the lower left button (on the left edge; below the volume buttons) to select. Allow up to 90 seconds for the reset to complete.

Attempt to restart your Note 8 to alternate boot modes

If the steps above won’t work and the screen remains black, the other thing that you can try is to turn it on to other boot modes. Android devices can also load other software environment namely Recovery Mode and Odin/Download Mode. Because each of these modes run independently of Android, it’s a good way to know if the black screen you’re having is caused by an operating system glitch or not. If you’ll be able to, say, boot your Note 8 to Recovery Mode and you can actually see that the screen works in this mode, that’s a clear indicator that software glitch is to blame.

Each boot mode offers you a way to potentially fix your issue. If the screen works only in Recovery Mode, you may be able to fix the screen by wiping the cache partition or doing a factory reset. On the other hand, if the screen only works in Odin Mode, you may need to flash a stock firmware or a custom ROM to permanently regain the function of your screen.

Below are the steps on how to restart your device to other modes.

How to restart your Note 8 to Recovery Mode:

  1. Power off the device. If you can’t turn it off normally, wait until the phone discharges the battery (you’ll know this because the LED light will not light up anymore). Once it’s drained its battery, recharge it for 30 minutes.
  2. Then, press and hold the Power, Volume Up and Bixby buttons at the same time.
  3. Keep pressing these keys for a while.
  4. If successful, you should see the Recovery screen.
  5. In recovery use Volume rocker keys to scroll up and down and Power button to select.

How to restart your Note 8 to Odin Mode:

  1. Power off the device. If you can’t turn it off normally, wait until the phone discharges the battery (you’ll know this because the LED light will not light up anymore). Once it’s drained its battery, recharge it for 30 minutes.
  2. Then, press and hold the Power, Volume Down and Bixby buttons at the same time.
  3. Keep pressing these keys for a while.
  4. If successful, you should see the Odin Mode screen.
  5. Just like in recovery use Volume rocker keys to scroll up and down and Power button to select.

Contact Samsung

If your phone’s screen stays black throughout, or if you nothing change after restarting to either Recovery or Odin modes, that’s a clear indicator that your Note 8 has suffered a permanent screen failure. In order to fix it again, the screen must be replaced. Samsung repairs are top notch so we highly recommend that you let them do the repair for you.
