This icon popped up on my screen today. I don't know how or what it does and how to remove it. I have a Redmi 4a.
Does anyone know to remove it?
That's DND (Do Not Disturb)
DND is a feature which after enabling you aren’t disturbed by notifications or other forms of incoming communication. Do Not Disturb(DND) can be set automatically or manually based on a few parameters that you control.
One way to disable DND is to drag down your Notification Panel and select DND from the different toggles.
Alternatively navigate to Settings >> Do Not Disturb and disable it.
