This article provides message reminder setting instructions for OPPO, ZTE (Nubia), Samsung, Lenovo, Vivo, Xiaomi, and Smartisan phones.

To fix the problem where users can't receive notifications in a timely manner after closing the Lark window, configure the app permissions as described below. This way, Lark will run in the background so users receive new notifications in real time.

I. Enable message reminders

1. OPPO phones

Tap Settings > Notifications and Status Bar > Notification Management, find Lark, and enable message notifications for it. Then, enable status bar and lock screen display.

2. ZTE (Nubia) phones

Tap Settings > App Management, and enable the switch for Lark.

3. Samsung phones

Tap Settings > Notifications, and enable notifications for Lark.

4. Lenovo phones

Tap Settings > Notification Center > App Notification and Priority Management, and set Allow Quick View for Lark.

5. Vivo phones

6. Xiaomi phones

II. Problems receiving new message reminders
