Can't turn slow charging alert pop up

[ArkNine]

I have a problem with my samsung A8 with re-enabling slow charging speed alert. I accidentally turn it off by clicking the "don't show this message again". And then, i found out that you have to enable the USB notification settings. But, it didn't work . So please help

Edit:

I use the reset settings option and the problem still didn't resolved.

Maybe it's just a system bug. Try wiping the cache partition, it might help

Hello, you can try to wipe cache partition your device and it doesn't affect your data, etc. it's just clear your cache on your phone
