If the Samsung Galaxy Note 8 or Note 9 no longer turns on the moment you press the power button, this black screen might be a persistent and exasperating problem. Especially when buttons light up like always but the screen doesn’t, and you don’t know what it’s wrong with it. You can try to connect it to a power outlet, just in case that the battery is too low. And you can try to hit the power key several times just to make sure that it isn’t stuck in the off position. These two solutions may or may not work, so, consider the following aspects.
You can always ask for some tech support!
If you don’t feel comfortable with trying all kinds of – or any kind of – solutions on your own, there’s no better time to ask for technical support than now. Having the Samsung Galaxy Note 8 or Note 9 physically checked in a store will certainly speed things up. If the warranty is still in place, you might even get a free replacement or, in any case, a free repair.
But if you are curious about finding a solution independently, with our guidance, you might actually have a chance. Even if you try our solutions presented below without success, you can always come back to this first option and ask a technician to look at it. But until then, here is what you can try:
Boot to the Recovery Mode
The purpose of switching the Samsung Galaxy Note 8 and Note 9 from the normal running mode to the recovery mode is simple. You want to clear the cache partition, hoping that this will help you get over any bug or cache problem that is currently blocking its normal functions.
To get to the Recovery Mode, you will have to firmly hold the three main hard keys: Power, Home, Volume Up. Hold them until the phone vibrates, and, after that, only hold the last two – Home and Volume. Let go of them when the Android System Recovery screen loads.
Once inside the Recovery Mode, you will be able to wipe the cache of the operating system by highlighting the Wipe Cache Partition option. Of course, the touchscreen isn’t working, which is why you will have to navigate through the Volume Down key. After you have highlighted this option, use the Power button to select it. When the wiping process is over, the smartphone will reboot on its own, back to the normal running mode.
Boot to Safe Mod
The purpose of switching the Samsung Galaxy Note 8 and Note 9 from the normal running mode to the safe mode is even more intuitive. When you’re in this mode, the only apps that will run will be the pre-loaded apps. If the screen turns on without any other problems, it’s your proof that the cause of the black screen is a third-party app.
You should get to that part by long-pressing the Power button until the Samsung screen loads. After that, long press the Volume Down key, until the phone restarts and you see the Safe Mode text at the lower left corner.
Now you’re in Safe Mode and you’re free to inspect the Samsung Note 8 and Note 9 screen problems.
