A power button that doesn’t work doesn’t sound like a big deal until it happens to you. If you ever find yourself trying to access a Samsung Galaxy Note 8 or Note 9 from a non-responsive power button, the following information should prove useful to you.
You’ll see that when the Power button decides to not respond to your actions, the phone will still look as if it’s working. The keys will light up, the button may even show that it’s moving down and up, as you press and release it, but the screen just won’t wake up. You might even hear it ringing and not be able to see anything on the screen or to answer the call. What do you do, you wonder?
The thing is that there aren’t too many well-known causes for this problem, yet there are two common solutions. One would be the Safe Mode, for a general testing and the confirmation that you’re looking at a problematic third-party app, while the other would be the Recovery mode and a return to the factory setting. The latter, as you probably know, will let your smartphone empty, which is why you might want to try the first one before anything else.
If booting the Samsung Galaxy Note 8 and Note 9 into Safe Mode by using the hard keys didn’t make the screen light up, it means that the problem is more serious. But if it did, you’ll have to remember what third-party app you have recently installed and that might have caused this nonresponsive display.
In the event that you just can’t figure it out, take the plunge and reset the Samsung Galaxy Note 8 or Note 9 to its factory setting. You’ll lose all the data, but you’ll start from scratch and, after you run the latest OS version, the device should work and the screen should wake up without difficulties.
