The Redmi 14C doesn’t support switching the Control center style.
For your reference, the reasons are as follows:
1. Whether the control center style can be switched depends on the specific model. Even with the same Xiaomi HyperOS or MIUI system, some devices support switching while others do not. The availability of this feature varies, so please refer to the specifications of your particular phone model;
2. On devices that do not support switching, the Control center is set to the previous style by default. In the old version, pulling down the status bar will display both toggles and notifications on a single interface. However, in the new version, pulling down on the left side of the status bar shows notifications, while pulling down on the right opens the Control center.
