For those who have not got Extra Dim

[mHappiee]

If you are onOneUi 4.1 and you have not got Extra Dim in your phone, then you canTRY searching in the Activities available in your Phone.

In A51, I don't see any button or dedicated section for extra dim, but I found an Activity which is Extra Dim and can be opened with some Activity Launcher app. 

( Here I've used Nova Launcher as I use this app as my Launcher )

.

There is Extra Dim on A51 was pointed out by :https://r2.community.samsung.com/t5/Galaxy-A/Etra-Dim-samsung-A51/td-p/11489950

Name of Extra Dim ActivitySearch in Activity -> Setting -> Extra Dim ( Accessibility also has an extra dim option, but that doesn't have much options in it )

Extra dim settings

A word ofCAUTION : Play with Activity at your own risk

And it is not guaranteed that your device will have Extra Dim
