You need to create and manage the event reminder via the Amazfit App. The watch will display your to-do list and vibrate to remind you in the set time. Open the Amazfit App, go to "Profile – Amazfit Verge Lite – Event reminder", and create the event reminder upon the tips on the page. An alert will pop up on the watch when the time set for the event arrives. You can choose to close it or remind you later.
To close it, tap the "×" button on the left. To make a delayed alert, you can tap the "Z" button on the right or long tap the home button. Then, the alarm will remind you 30min later.
