I prepared a video tutorial for you: https://youtu.be/8cp88G3Nf0I
You can also delete a system cache following this article: Tips and tricks: troubleshooting
If my answer is helpful, can you set it as aolution? Thanks
I asked my friend who has Note9 which time has his Note9. There is also an option to do a hard reset but please wait until he responses.
Unfortunatelly, I have confirmed that the max. time is now 10s on Note9 😞
