Fix if Galaxy S20 Won’t Turn ON

Here are a few solutions to the problem where your Galaxy S20 won’t turn ON:

Check For Visible Damage

If your Galaxy S20 won’t turn ON, the first thing that you want to check is the possibility that bad hardware may be to blame. Does your Galaxy S20 has cracks or marks of hardware damage? Such things are usually the result of having dropped the device or hit the phone with something hard. These two are usually the reasons for serious hardware malfunction on phones.

Visit your local Samsung store or Service Center so a qualified Samsung technician can examine the hardware.

Use another set of charging accessories

If your Galaxy S20 still won’t turn on at this point, you want to make sure that the reason for it is not the charging accessories. If you can borrow another charging cable or adapter from someone, that would be great. It’s the easiest way to test if the current set you are using is defective or not. If you have a defective charger, it can be the reason why the device is not turning on.

Simple Reboot or Forced reboot

Well, I think you already know how to restart your phone. So just restart the device and see whether it solves the issue or not. Restarting a device is always an ultimate solution for any issue. Not only Pixel but this applies to each and every electronic device. I used to tell my mom to restart her device if she faces any issue with her smartphone.

Well if you still need to know how to restart then, here is it: Press your phone’s power button. On the screen, tap Restart.

The other way of the reboot is as follows:

  • Press and hold the Volume Down button.
  • While holding it down, press and hold the Power key.
  • Keep the button held for 10 seconds, it will be restarted automatically.

If this doesn’t work then head to the next method.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

  1. Open the Settings app.
  2. Tap Device Care.
  3. Tap the 3-dot at the top.
  4. Select Auto restart.

Check for “Moisture detected” error

“Moisture Detected” is an unusual error that is not usually expected in an IP68 rated smartphone like Samsung Galaxy S20/S20 Plus and S20 Ultra. But if you are facing the Moisture Detected error in your Samsung Galaxy S20/S20 Plus and S20 Ultra then follow the below-linked article to fix it.

Check for the Black Screen issue

Black Screen issue is usually indicated by, as the name suggests, black screen. The screen remains black or unresponsive even though there are signs that the phone may still be functional. If your Galaxy S20 won’t turn on or the screen stays black but it continues to make a sound when there’s incoming messages or alerts, still vibrates when you try to restart it through the Power button, then you have Black Screen issue at hand. No Power issue on the hand has the device totally unresponsive and there’s the total absence of signs that the S20 is still working.

If you have a Black screen problem, the best thing to proceed from here on is to have the phone examined by a professional, preferably someone from Samsung Service Center.

Troubleshoot apps in Safe Mode

In case you don’t know what is safe mode, in safe mode, the system temporarily disable all third-party applications you installed on your device. By doing this we can figure out which app is occurring the problem. Follow the below step to turn Safe Mode on:

  • Turn OFF the device.
  • Press and hold your device’s Power button till the model name screen.
  • When the SAMSUNG logo appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

After figuring out the apps which are creating the problem, follow the below steps to uninstall it(if required):

  • Open Settings from Launcher.
  • Tap on Apps.
  • Tap See All Apps.
  • Tap an app that you want to uninstall
  • Tap Uninstall.
  • Tap OK to confirm.

Try to Boot in Recovery Mode

In case you don’t know what is recovery, the first thing the bootloader rings up is the recovery. Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it. Follow the below instructions to do so:

  • Turn off your phone.
  • Once it is turned off. Press and hold the power/Bixby and volume down button simultaneously until the Android logo pops up.
  • When the green Android logo displays, release both buttons.
  • The Recovery screen menu will now appear

If your Galaxy S20 boots up to Recovery fine, you’ll then need to wipe it with a factory reset, which is one of the options in the Recovery menu.


Factory reset will delete everything, so you want to make sure that you create a copy of your personal data such as photos, videos, documents, texts, etc. ahead of time.


  • While you are in Recovery Screen.
  • Use the Volume Down button until you are highlighting ‘Wipe data/factory reset.’
  • Press the Power button to select ‘Wipe data/factory reset.’
  • Use Volume Down to highlight Yes.
  • Press the Power button to confirm the action to clear your phone data.

Visit the Service Centre

Although it’s rare, some cases of overheating issues on Samsung Galaxy devices may have bad hardware as the origin. If a factory reset won’t help in fixing your issue, visit your local Samsung store or Service Center so a qualified Samsung technician can examine the hardware. If needed, they may send it in for repair or replacement.
