Samsung Galaxy S10 blacked out and won’t turn on

Some owners of the Samsung Galaxy S10 has reported that their units blacked out and won’t turn on or respond after that. This kind of problem could be a serious one especially if you used the device underwater. I understand that it’s water-resistant but there’s always a limit to that as the IP68 certification isn’t really a guarantee that your phone is waterproof. Another angle you have to look at is that it could be a physical damage especially if the phone got dropped on a hard surface or there are signs of physical damage. 

In this post, I will help you in troubleshooting your Galaxy S10 that blacked out and would no longer turn back on. We will look into the most common cause of this problem and I will also give you the most effective solution. So, if you’re one of the owners of this device and are currently being bugged by the same problem, read on as this article may be able to help you one way or another.

Troubleshooting Galaxy S10 that blacked out and won’t turn on

First off, make sure that your phone doesn’t have any signs of physical or liquid damage because if there is, then there’s no use in troubleshooting your device. Simply bring it to the store and let the technician assess the problem. If the issue is minor, the tech may be able to fix it. 

On the other hand, if this problem occurred without apparent reason or cause, then you can consider this problem as one of the cases of the Black Screen of Death. Most of the time users think that it’s a hardware problem since the phone no longer responds, however, it’s actually just a minor issue with the firmware that you yourself could fix. With that being said, here’s what I suggest you do about this: 

First solution: Perform the simulated battery removal

If you owned one of the basic phones or early smartphones with removable battery, you will easily understand what this procedure is trying to do. The simulated battery removal, or forced restart, is done on phones with non-removable batteries. You just have to press and hold a combination of buttons and your phone will reboot and refresh its memory as well as reload all its apps and services. Here’s how it’s done: 

  1. Press and hold the Volume Down button and don’t release it yet. 
  2. While holding down the volume button, press and hold the Power key as well. 
  3. Keep both keys held down together for 15 seconds or until the Galaxy S10 logo shows on the screen.

If you were able to make the logo show up, then the problem is already fixed as the phone responded. However, if it remains to be unresponsive, try doing the same procedure a few more times and move on to the next procedure if it stays on its blacked out state and won’t respond.

Second solution: Try charging your phone and do the forced restart

There are times when a simple battery draining issue can also result in a system crash. If your phone remained on a black screen after doing the first procedure a few times, then the problem could be due to a drained battery that may have resulted in a system crash. 

Having a drained battery isn’t always an issue because most of the time the device would respond when it’s connected to the charger. But if you let your phone run out of battery, the firmware may crash and then you’ll be having a phone that’s blacked out and not responding. Here’s what you need to do to address this possibility: 

  1. Plug the charger to a working wall outlet. 
  2. Using the original cable, connect the phone to its charger. 
  3. Regardless of whether the phone shows the charging symbol or not, leave it connected to the charger for at least 10 minutes. 
  4. After which and while the phone is still connected to the charger, press and hold the Volume Down button and don’t release it yet. 
  5. While holding down the volume button, press and hold the Power key as well. 
  6. Keep both keys held down together for 15 seconds or until the Galaxy S10 logo shows on the screen.

If this is just a minor issue, then your phone should already be booting up by now. However, if it remains on a blacked out state and still won’t turn on, then you need to bring the phone back to the store so that a technician can check it for you.

If you were successful to make the phone respond but the problem occurs from time to time, then a reset is all you need to do to make the device work perfectly again. Prior to the reset, don’t forget to backup your files and data and then remove your Google and Samsung accounts so that you won’t be locked out. Once ready, follow these steps to reset your phone: 

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows, release all three keys.
  4. Your Galaxy S10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
