What to do if the screen of your Galaxy Note 9 does not turn on again? Some users do experience this problem after a while. The smartphone works perfectly well, but when the screen goes to sleep, you can’t turn it back on. This bug can occur on other smartphones, regardless of their brand. Here are some steps to help you find a solution.
Hard to deny it: the Galaxy Note 9 remains one of the best smartphones on the market, even in 2019. This smartphone is resolutely oriented towards the professional sector with its stylus, its DeX mode , its muscular technical data sheet based on Snapdragon 845 Exynos 9810 and its price which exceeds 1000 €. Which does not make him immune to bugs. One of them, reports TheDroidGuy site, prevents the screen from turning on again. The precise description of the problem is as follows: the smartphone operates normally, until it locks and the screen turns off. It is therefore impossible to switch it on either via the ON button or the fingerprint sensor. Only a restart allows you to turn the screen back on. So what if you are affected by this kind of problem?

Galaxy Note 9: the solution to the screen problem that does not turn back on
This bug can actually be caused by a multitude of causes, mostly software – although hardware causes are not ruled out in some cases. To find the source of the problem and put an end to it, you must therefore follow these steps:
1. Update your Note 9
Sometimes a simple update can put an end to a bug:
- Go to Settings> Update
- Go to Download and install to manually start the update if available
The problem is not solved? Continue to the next step.
2. Try to restart the smartphone in safe mode
If an app you recently downloaded is responsible for the problem, you can only confirm it in Safe Mode. Safe mode prevents the system from launching applications that have not been preinstalled by the manufacturer. You will therefore be able to see in safe mode whether the screen turns back on or not as it should:
- Turn off the smartphone completely
- Press and hold the ON button until the Samsung logo appears
- Immediately after, release the ON button and press the Volume Down button until the device finishes restarting
- Once Safe Mode is visible at the bottom left of the screen, you can release Volume Low
If it didn’t work, go to step 3.
3. Erase the cache partition
It sometimes happens that the cache generated by applications is corrupted, generating this type of bugs. This sometimes occurs after a certain time of use. In addition to this problem, a corrupt cache can cause overheating, loss of autonomy or crashes. It is possible to delete the application cache after application. Here we suggest you opt for a faster and more radical solution that will completely erase the contents of the cache partition:
- Turn off the smartphone completely
- Keep the Volume Up , Bixby and ON buttons pressed until the Android logo appears
- Release all buttons
- Once in the recovery menu, navigate with the Volume Down button until wipe cache partition
- Press the ON button to select
- Press Volume Down and then ON to select Yes
- Once the partition is erased, restart the smartphone
If these steps did not work, there is the option to do a full reset.
4. Reset your smartphone completely
This step implies that all the data on your smartphone will be erased. To be used as a last resort, therefore, once these data have been duly saved :
- Turn off the smartphone completely
- Keep the Volume Up , Bixby and ON buttons pressed until the Android logo appears
- Release all buttons
- Once in the recovery menu, navigate with the Volume Down button to wipe data / factory reset
- Press the ON button to select
- Press Volume Down and then ON to select Yes
- Restart the smartphone
Normally everything should work. If not, we have bad news: it is now sure that this is not a software problem…
5. Contact Samsung for repair
If you have carried out steps 1 to 4 without success, then your smartphone is the victim of a technical problem or is defective. The only solution is then to get in touch with Samsung to schedule a repair.
