The only context when your Samsung Galaxy Note 8 or Note 9 screen is allowed to turn black is when you turn it off. Anything else is unacceptable, though, possible, which is why it is better to be prepared.
When the display of the Note 8 and Note 9 turns black and nothing shows up, despite the buttons lighting up as they normally do, looks like it fails to wake up. To solve this problem, we have at least three different suggestions for you.
#1 – Perform a factory reset on Samsung Galaxy Note 8 or Note 9
This kind of solution usually works for all kinds of problems. The main issue with it is that it comes with a general wipe of everything you had on the device. When you do it, you have to be aware that, unless you create a copy of your data, you will lose it all. Assuming you’ve taken care of it, here is a guide with specific steps on how to factory reset your Samsung Galaxy Note 8.
#2 – Perform a wipe cache partition on Samsung Galaxy Note 8 or Note 9
If you don’t like the idea of wiping everything from your smartphone, try to wipe just the cache memory first. You’ll have to switch from the regular running mode to the Recovery Mode:
- Press and hold the three main buttons for Volume Up, Home, Power;
- Wait until the phone vibrates;
- Release the Power button;
- Hold the two other buttons, until you see the Android System Recovery screen loading;
- Head to the Wipe Cache Partition option with the Volume Down key;
- Activate the option once you have highlighted it, with the Power key;
- Wait for it to finish and the phone will restart.

#3 – Take the Samsung Galaxy Note 8 to an authorized service
Maybe you haven’t tried it all, but if you have wiped the cache and you have returned the device to its factory defaults without success, there’s nothing else that you can do. A technician will most likely have many other options and tools at hand. Even if you’ll get the news that your Samsung Galaxy Note 8 or Note 9 needs a replacement, at least it will come from a trusted source.
