In this troubleshooting guide, we will show you what to do if your Galaxy Note 20 turned off by itself and would no longer respond or turn on after that. You will also learn the most common reason why such a problem occurs and how to prevent it from happening again.
Most of the time, when a high-end device like the Galaxy Note 20 powers off by itself and gets stuck on a black screen, we think it’s a hardware problem. Some of the cases are like that, especially if the device was accidentally dropped on a hard or wet surface. However, if there’s no visible signs of physical damage and the phone just powered off without apparent reason, it’s often due to a firmware-related issue.
Firmware issues can affect the overall performance of your device no matter how powerful it is, but they’re not necessarily hard to fix. In this case wherein your phone is stuck on a black screen or won’t turn on, you only need one or a couple of procedures to fix it. Here’s what you need to do:
First solution: Force restart your Note 20
In most cases, when a problem gets stuck on a black screen and would no longer respond, the problem is due to a firmware crash. It may seem like the problem is pretty serious as the device won’t respond anymore, but in reality, it’s actually pretty easy to fix.
- What you have to do is press and hold the volume down button and the power key at the same time for 10 seconds. This will trigger your device to boot up.
- So when the logo shows, release both keys and just wait until your Note 20 completes the boot process.
Most of the time, this procedure is enough to make your phone work perfectly again. However, it still won’t respond after this, you should try the next solution.
Second solution: Charge your phone and do the forced restart
After doing the first solution and your Galaxy Note 20 still won’t turn on, then it’s possible that the battery is totally drained.The thing about battery drain is that, there’s a tendency the firmware will crash if left to run out of juice. That might be the case here, so here’s what you need to do:
- Plug the power adapter to a working wall outlet.
- Using the original cable, connect the Note 20 to its charger. Regardless of whether the charging sign is showing or not, leave it connected to the charger for at least 10 minutes.
- After that, try pressing and holding the volume down button and the power key for 10 seconds while it’s still connected to the charger.
- If the logo shows, then release both keys, if not, continue holding them a little longer.
When it comes to fixing an Android smartphone that won’t turn on is concerned, these two procedures are enough to fix it. But if it doesn’t help, then it’s time you have the phone checked. These procedures are also enough to tell you if the problem is serious or not.
