This is the standard A12 design (units you have a Samsung or a Realme). Afaik, it cannot be changed. Comes with the update to LOS19.Another small cosmetic issue.
How can I change number of quick settings panel icons?
Somehow (I am not even sure now) I managed to have only 4 icons in the panel.
I want to remove one more and enable 3 tiles in a row, so I get one row which is more convenient.
Is it possible?
