However, recently many users have raised a concern regarding the phone. For some users, the S8 has developed an issue of not turning on after it has been switched off. This article aims to alleviate this concern by explaining some common causes and fixes for this issue!

Why Won’t Samsung Galaxy S8 Turn On?

It’s not the first time that a Samsung device is giving power-up issues to its users after a couple of years of using it. In fact, we observed a similar issue in the previous flagship from Samsung as well! Since the device uses complicated tech mechanisms that work with each other, the problem could be in any one of them. Therefore, it is very difficult to pinpoint the reason for this issue. However, this section discusses some probable reasons why the S8 does not turn on for a few users.

  • A lack of charging, not pressing the power button correctly, or other such logistical reasons may very well be the cause for this issue. Even new devices can have the charging issue since they are lightly charged in the Samsung factories. They could lose their charge during the time the device makes its way to you. So, just to be on the safe side and exclude all other causes, you should charge your phone for a couple of hours with the original Samsung charger. If it still does not work, you can move on to the other causes in this section.
  • The phone may not be able to turn itself on due to a system hindrance. In premium and cheaper Android phones, this issue is pretty common. The phone’s firmware may crash out of the blue and would cause this system failure. In effect, your phone would not be able to turn itself on. In older phones, this problem could be fixed by removing the battery from the phone for some time. However, since the S8 does not have a removable battery, there are other ways to fix this issue. You can learn about the possible fixes in the next section; so, let’s move on to more probable causes for this issue.
  • Another possibility with this issue could be a fault in the charger or the charging port. If the phone is not picking up any charge, it means that the battery cannot power it up. This issue can be observed from the charging LED that is visible when the phone is charging. If the LED is not showing, you could try a different charger and a different outlet. However, if the issue persists, then there are no real workarounds for this problem; you will have to take it back to the shop or a Samsung service center.
  • Many of the cases reported to us by S8 users started after a software update. Therefore, a software issue might also cause the power-up issue on the S8. Small glitches after each update may cause one of the components in the code of the software to malfunction. The company usually resolves these bugs through a security patch. However, until the patch is released, the users are in huge jeopardy. You do not have to worry, though, since all the solutions for such problems are discussed in the next section.

Connect your phone to the Samsung official charger for at least an hour, even if the LED is not lighting up. The LED usually takes a couple of minutes to light up if the phone has a really low battery. Confirm that your outlet and the charger are both working.

  3. If the phone responds yet there are still some minor glitches; then you must have it check out by a Samsung service center.

3.Safe Mode Boot Up

A safe mode disables few features of the phone for safety purposes. You can try to access the phone in this mode if you are facing this issue. If the issue is caused by one of the components switched off in a safe mode boot up, then the safe mode is likely to power up your phone. Follow the steps below to implement this solution.

  2. Release the button once the company logo appears on the screen.
  3. Immediately press the volume down key! Keep it pressed until the safe mode has been successfully initiated.
