Zen mode is a feature available on Realme phones that restricts and hides all apps, blocks all messages and notifications, and helps users focus on their work or other activities. It is similar to the Focus mode available on other devices. To enable Zen mode on a Realme phone, users can swipe down the notification tray and tap on the Modes toggle. Once enabled, Zen mode cannot be turned off until the set time period is over. Zen mode is available on Realme UI 4.0 and above.
