If a high-end phone like the Samsung Galaxy Note 8 becomes unresponsive and won’t turn on, depending on how the problem started, there’s always something you can do about it especially if the issue occurred without apparent reason or cause. As the owner, you should be the first one to know the events or factors that resulted to this problem.

Quick fix for Galaxy Note 8 that won’t turn on
Most of the time when the phone’s screen turns black and unresponsive for no apparent reason, it’s a firmware crash. The same is true for units who are left charging overnight but found out to be dead in the morning and won’t turn back on. Many of the complaints we received from our readers regarding this problem were sent after an update so there’s also a possibility that this is due to a firmware issue. But assuming that the problem started out of the blue, the best solution to it is Forced Restart.

In Galaxy Note 8, a forced restart will simulate battery disconnect which may refresh the device’s memory. It’s actually the same as the battery pull procedure we often do to phone with removable batteries. It’s a simple procedure yet very effective in dealing with issues like this. To do this, press and hold the Volume Down and the Power key simultaneously for 10 seconds or until the screen flickers and logos start to appear on the screen. Do the same procedure a few more times if the phone won’t respond to your first attempt or try to press and hold the Volume Down button first and without letting go of it, press and hold the Power key. Keep both keys held for 10 seconds.
If the phone boots up, then you can consider the problem fixed at this point but there’s no guarantee this would never happen again in the future but at least, you now know what to do if the phone becomes unresponsive again.
If, after several attempts, your phone still won’t boot up, then it’s time to troubleshoot it. Move on to the next section for that.

Troubleshooting Note 8 that won’t respond to Forced Restart
I understand that some owners are hesitant to troubleshoot their devices especially new Android users. So, if you are not comfortable following the procedures below, just bring the phone to the service center so that you can be accommodated by a Samsung tech. For those who are willing to do a couple of procedures to see if the phone turns, here’s what I suggest you do…
Check for signs of physical and/or liquid damage
Look for scratches, dents and cracks as any force that could render the phone useless should leave a mark on the outside. If the phone looks flawless or has some minor scratches, then it’s not physical damage that caused this.
As to liquid damage, here’s what you should do…
- Look into the USB/charger port to find trace of water.
- Use a cotton swab to clean around the area or insert a small piece of tissue paper to absorb the moisture.
- Blow into the port to get rid of any foreign objects that may interfere with the circuit.
- Remove the SIM card tray and look into the SIM slot to find the Liquid Damage Indicator (LDI).
- If the LDI is white (it’s the original color), then there’s no water damage.
- If the LDI however, turned red, pink or purple, then it’s clear the cause of the problem is liquid damage.
In case of physical and/or liquid damage, bring the phone to the tech as there’s only so much you can do about it.
Try charging your phone to see if it would respond
It’s possible that the battery got drained and a few seconds before the battery got totally depleted, the system may have crashed leaving the phone without power and a crashed system. This would surely result to a blank screen, unresponsive keys and not charging issue.
I understand the phone won’t charge if the system crashed so regardless whether the phone responds to its charger or not, leave it plugged in for ten minutes after which, try turning it on. If it still won’t respond, then do the Forced Restart procedure again but this time while the phone is plugged in.
Basically, what we’re trying to accomplish here is to…
- find out if the phone responds to its charger,
- know if it’s just a drained battery issue,
- and determine if the phone would respond to Forced Restart while charging.
If this procedure fails like the first one, the next procedures will be to test your phone if it’s still capable of turning its components on.
Try running the phone in Safe mode
There’s a small possibility that the problem is due to some apps you installed. So we will try to disable all those apps at once and see if the phone boots up. You can do so by running the phone in safe mode:
- Turn the device off.
- Press and hold the Power key past the model name screen.
- When “SAMSUNG” appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume down key when you see Safe Mode.
If the phone starts in this mode, then you can consider the problem fixed as the phone finally turned on. The next minor thing to do is find the app that’s causing the problem and uninstall it. However, if the phone still won’t boot up in this mode, then try the next one.
Boot the phone up in Recovery mode
This is the final test. If it still fails to turn the phone on, you should bring the device to the service center as it might be an issue with the hardware. But if you can successfully boot the device in Recovery Mode, then you can try wiping the cache partition and/or do the Master reset. Both of these procedures can surely bring the phone back to its normal operation and performance.
How to boot Note 8 in Recovery Mode and wipe cache partition
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe cache partition’.
- Press Power button to select.
- Press the Volume down key until ‘yes’ is highlighted and press the Power button.
- When the wipe cache partition is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
How to boot Note 8 in Recovery Mode and do the Master Reset
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight “wipe data / factory reset.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
