Samsung One UI 4.1: Reminders, register and receive notifications!



Samsung One UI 4.1 Reminder is an ultimate listing application. Register to do items as reminders and receive notifications according to the conditions you apply. This is a great thing because we have lots of work to do in a day, frankly speaking, it is a human habit, we cannot remember all of them together if we do not list them. As a result, some of our tasks get delayed and remain pending.

Samsung reminder works just like setting an alarm for all your work that you might have listed for specific hours, days, or months. I only suggest you keep your phone always synchronized. It facilitates the smartphone user not only to get event reminders but the location too. So please keep your GPS activated. If you will not regularly update them. You will be unable to get reminders about them.


Samsung Reminder

How to set reminders?

  • launch the Calendar app
  • Tap on Reminder
  • The Reminder screen will appear
  • As you click on the Reminder icon, a shortcut will be added to the Apps screen.

There is an alternate way to do this

  • Launch the Reminder app
  • Tap on the Plus sign available at the bottom right of the screen, enter the details, what to notify mention the date and time, then click to set a notification and put it on.

Now, all the notifications, which you set always appear in the form of a list in front of you. Here you have the facility to edit or review them. When you complete your task, you can mark it as completed by tapping on the square tile.

User is free to choose the category of reminders, smartphone user has the facility to restore reminders if they need to perform the task repetitively. As you choose this option, a reminder will be back on the list.


Deleting the reminder is very easy, to delete the reminder, you have to select it and then tap on the delete option. In my view, the Calendar application together with the Reminder app serves the purpose in a better way. Do not wait, list up things and get started. Make sure you are connected to Wi-Fi or a cellular network.
