Screen in samsung galaxy The S8 is just great - high contrast, bright, big, great resolution, etc. But, at the same time, he has one flaw. At one "perfect" moment, it can turn completely black and not react in any way to your pressing.
Of course, in most cases, it is not the display itself that is to blame, but the smartphone with its operating system as a whole. But do not be upset if your Galaxy S8 shows a black picture instead of an image - it is quite possible that you can fix everything yourself without resorting to the help of service center masters. And here's what you can do...
Charger
Yes, it sounds trite, but it's still worth checking if your Galaxy S8 is charged. True, when the smartphone does not show anything, it is quite problematic to do this. Therefore, we act in this way - we connect Charger and wait 30 minutes. Why so long? This is done in case the battery is in a state of very deep discharge.
To complete the picture, you can take a more powerful power supply and replace the wire. Just to almost completely eliminate problems with the charger and battery.
Crashes in the operating system
Sometimes, the display may turn off while you are using the device. And although this can also be "written off" to problems with the battery, in this case, most often we are talking about "glitches" in the system. How to deal with them?
By the way, there is one more "folk" advice from our reader and. In short, the user's smartphone hung and the only thing that saved him was pressing all the buttons at the same time. It seems to us that if the blackness of the display is caused precisely by such “minor” failures in the Android OS, this option should also help.
"Iron" problems
Unfortunately, this is the most unpleasant option - the display may not show information due to its breakdown. Not necessarily it will be physical damage, the probability of marriage, too, has not been canceled. There will be only one way out - visiting the official service center for the purpose of warranty repairs. Repairing the Galaxy S8 screen on your own is almost impossible.
But we, as usual, sincerely hope that things will not come to such drastic measures. And if you still have to visit the ASC, then the repair will be quick and of high quality.
P.S. Write your story in the comments (what worked and what didn't?) and if the screen of your Galaxy S8 is no longer black, "celebrate" this event with a "like"!

Remove SIM Card
Shut down your Galaxy and pull out SIM card. Now re-insert the Sim after a few seconds, turn on the phone and see if anything has changed?
Boot Phone in Safe Mode
This is another helpful step to get rid of touchscreen issues if it is some third party application that is causing the problem. Safe mode temporarily disables everything third party applications, and if you are not facing the issue in this mode, it must be a third party app causing this issue.

If you have a lot of apps, it can take a long time to uninstall them one by one, so you can perform a factory data reset (explained below).

This can happen if you play games or make videos for a very long time. Wait a while before using your phone again.

Not every person keeps a close eye on their smartphone. Quite often, unforeseen situations arise due to the fact that the device does not turn on or the screen on Samsung does not work. This can happen for completely different reasons, ranging from ordinary mechanical damage to factory defects. Let's look at the most common reasons why a smartphone stops functioning correctly.
Let's first analyze the banal problems due to which the screen may stop working. Let's start with the difficulties that can be associated with the battery. Most often, the battery simply does not receive the proper amount of energy from the charger. On Samsung, this can happen as a result of a faulty charger that stops working properly, as a result of a burn-out chip inside the power supply.
Such cases are not rare and happen all the time, as a result of strong voltage drops. With a significant increase in the input voltage, the board burns out. It's good if the charger suffers, and not the device itself.
It is also worth mentioning that the battery can fail, but this rarely happens on devices from this company. A similar problem can be solved by simply replacing the battery with a new one. You can do it yourself, just choose the right battery.

- Damage to the screen control chip. If the screen of a Samsung device does not turn on, this does not mean that the display is to blame for everything. It is not uncommon for people to replace the screen, but the problem is still not solved. Replacing the chip is quite cheap, which allows you to solve the problem as quickly and efficiently as possible. It is not recommended to do this on your own, as you need specialized equipment for soldering boards.
- Damage to the connection between the connector and the printed circuit board. This situation is as simple as possible. To solve it, you only need to disassemble the smartphone, the screen of which has gone out, and insert the detached part in its place. 90% that this method will help your device.

Operating system errors
If the device freezes and does not turn on after that, then it is likely that the main problem lies precisely in the operating system. The Android OS (especially older versions) is not known for its stability, so sudden errors can occur regardless of the brand and model of the smartphone.
In such situations, not everything is clear, because in most cases, when the screen does not turn on, and the problem arose after freezing, you just need to pull out the battery for a couple of minutes, after which, most likely, the device will start without problems. Unfortunately, it is not always possible to solve the problem in this way, because sometimes the phone does not start even after that, and some devices are equipped with a non-removable battery (use the reset button located on the smartphone case). Where to find it, read the instructions.
If all the tips that were given above could not help you, then you will have to reset the device to factory settings. Unfortunately, all your data will be deleted, but the good news is that operating system will start functioning normally again. Follow the instructions below:
