Clicked by Accident!! HELP!!

[Clancularius]

Usually, I always receive Slow Charging notification whenever I connect my Samsung A7 (2018) to a USB charger. The thing is, I accidentally I clicked [Don't show again] option which disables the said notification. 

I want to enable this option again for it tells me if the USB Charger is working pretty well and in best condition.... 

I already checked some forums and tried the 2 main options given but to no avail...

Option 1: Disable/Enable Fast Charging 》 Sadly, my phone doesn't support Fast Charging so this option is unavailable...

Option 2: Enable/Disable USB under System UI or Android System 》 I managed to find the said option but it was grayed-out and can't be tampered...

PLEASE HELP ME!!! WHAT ARE MY OTHER OPTIONS?!

Try to reset your settings...not factory reset huh?hahahaha just the settings Application

[Thaddeus47 · Accepted solution]

The only option I can think of is to do a hard reset so every setting goes back to default.

This means you lose everything though, so do this as a last option.

guess it comes down to Hard Reset huh.... 😢
I'll take it as a last resort then if there are no other solutions given... Thank you very much...

[Clancularius]

Nope... didn't fixed it... 🙁 Thanks tho

Update:

So I tried doing these recommended steps:

Step 1: Reset Application References (with the System Apps as well)

Step 2: Reset settings to its Default

Then purposedly used a Not-so-good USB Charger..... but the Notification still doesn't pop-out....

Any other solutions? (Other than Hard/Factory Reset)

I didn't managed to find the exact solution to undo what I did even with the help of Customer Service (was advised to do Hard/Factory Reset in the end, to which I didn't follow)....

But I did managed to make a Compromised Solution...
