No smartphone is perfect and even if it looks like that, it will stop being, at some point. Take the most popular smartphones from Samsung, their latest flagship for the time being, as an example. Samsung Galaxy S8 and Galaxy S8+ Plus can cause you some problems on different occasions. For instance, some users complained that the Power button, the side button that you use to turn the device on/off or to wake up the screen, becomes unresponsive.
It usually happens that you simply touch the side button and while the soft keys on the display light up, the screen doesn’t wake up, it just remains black and unresponsive. The same black screen can also manifest when you’re getting a call but you can’t really see anything on the display, nor swiping to take the call or to reject it.
In this article, we’re going to help you to troubleshoot on the Galaxy S8 and Galaxy S8+ Plus side button not working. If you’ve had similar problems with your power button lately, here is what you should consider.
Step 1 – Investigate in Safe Mode
This should be your first troubleshooting step especially if you have recently installed a new app. While we don’t have any specific reports indicating that a particular app or even malware could make the power button to stop working and the display to light up, it is best to start this way.

Step 2 – Try a Factory Reset
If you couldn’t find or fix anything from running the smartphone in Safe Mode, you need to perform a factory reset. As you probably know, this will erase all the data on your device and restore it to the original settings. This is why you will first have to back up all the important data if you have information that you want to keep. Only then you can reset you Samsung Galaxy S8+ Plus to its initial settings. When you’re done, install the backup that you have previously created.
Step 3 – Check your system version
After the factory reset, you also have to make sure that you are running the most recent system update version available for your Samsung Galaxy S8 or Galaxy S8+ Plus. If you’re not sure what would that be, contact the service provider and it should tell you for sure.
