What does com.sec.android.daemonapp mean?

com.sec.android.daemonapp is the Android package file of the Unified Daemon(EUR) system application designed by Samsung that includes Weather, Stock, and News apps for Samsung devices running on the Android OS.

The Unified Daemon system application shows the total data usage from Accuweather.com, Yahoo Finance, and Yahoo News. The data is requested by Alarm, Desk Clock, S Planner, Camera, and Briefing app.

This application is present on selected Samsung devices only. You can find this system application by going to Settings > Data usage > Unified Daemon.

Daemon vs Service

A Daemon is a program that runs continuously in the background and handles periodic service requests received by the computer system.

A Daemon program doesn’t have a controlling terminal which means Daemon programs are non-interactive and do not have a Graphical User Interface(GUI).

Some examples of Daemon are inetd, httpd, nfsd, and sshd.

A Service, on the other hand, is a program that responds to requests from other software and performs automated tasks without requiring interaction from a user. A service has a controlling terminal which means it is interactive and has a Graphical User Interface(GUI).

Examples of Services are File sharing applications. A Daemon is a subset of services.

How to Reduce Data Usage of com.sec.android.daemonapp?

The data usage of com.sec.android.daemonapp(Unified Daemon app) differs according to the user’s settings. If you set up more cities in the Weather app, it will require more data to refresh the weather for these cities than if you set fewer cities in the Weather app.

Similarly, if you set up Stocks and Categories for a lot of different companies in the Yahoo Finance app and then it will consume more data.

The data usage of the Unified Daemon(EUR) app depends on the app’s refresh period. The refresh period is the time period after which an app automatically updates its content.

If you choose a low refresh period like 1 hour the app will update its content after every 1 hour so the data usage will be more than if you choose a higher refresh period.

To reduce data usage, you have to select a high refresh period.

The Unified Daemon(EUR) system app has five settings for the refresh period – None, 1 hour, 3 hours, 6 hours, and 12 hours. It’s better to select a high refresh period like 6 hours or 12 hours based on your preferences to reduce data usage.

For example, if you want to change the refresh period of the Yahoo Finance app you’ll have to follow the steps mentioned below.

  1. Go to Settings.
  2. Tap on Apps.
  3. Find the Yahoo Finance app from the list and tap on the Settings option(Gear icon) beside it.
  4. Select Refresh time for the app. Make sure to set it high like 6 hours or 12 hours to reduce data consumption.

Repeat the above steps for the Weather app to reduce its data consumption.

How to Restrict Background Data of com.sec.android.daemonapp?

Restricting the background data is another way to reduce the data consumption of apps. As I mentioned earlier, com.sec.android.daemonapp is the Android package of the Unified Daemon app so don’t get confused if you see Unified Daemon in the settings.

1. Go to Settings.

2. Tap on Data Usage.

3. Scroll down and tap on Unified Daemon.

4. Tap on the toggle button to enable Restrict Background Data.
