If you have installed an app and access it often, it makes sense to place it directly on the Home screen.
You can learn how to place an app from the App menu on the start screen of the Samsung Galaxy A7 (2018) here:
To do this, first open the App menu on your smartphone and then scroll to the page where you can see the app you want to move to the Home screen.
Now you have to press and hold the app until it can be added to the start screen of the Samsung Galaxy A7 (2018). The app can be moved as long as you keep your finger on the screen.
Placing the app on the Home screen
Release the app to place it on the home screen.
Do this with all the apps you want to add to the Samsung Galaxy A7 (2018) Homescreen.
