One of the most repeated errors has to do with the renewed control center of MIUI 12. With it activated, users try to access the notifications of the smartphone that appear at the top, but nevertheless there is no way to see them and only on rare occasions is it possible to access them. This, however, is a learning error, as we only have to bear in mind that by sliding from the left side of the screen we see the notifications and on the right we will see the shortcuts.
Alternative solution
In case we do not like this method, we can change the style of MIUI 12 notifications and return to the classic one that we found in MIUI 11. This will only take us a few quick steps to enter Settings> Display> Control center and bar notifications and finally we deactivate the possibility of using the new control center.
