The Android operating system supports a user interface revolving around a couple of main elements, like the lock screen, the notification panel, the app drawer and the home screens. The home screens are where majority of the users spend their time. They allow a lot of customization, where users can select wallpapers (static and live), place various widgets and shortcuts. By default, there are about five to seven home screens at a user’s disposal; however, these can be modified easily (you can reduce the number, but not increase over the maximum possible). Mostly, home screens are crowded by app icons, which are shortcuts for easy accessibility. You can always add more app shortcuts, but at times you may want to clear up your home screens.
Unlock your device and navigate to the home screen you wish to remove icons from. You can swipe left or right on your screen to access the different home screens.
Once you are on a home screen which has icons you wish to remove, long press an icon (keep your finger on till the interface changes and do not lift your finger) and the UI should change to show you available options.
Do not lift your finger and look at the options available to you. You may have the option to create a folder, create a new page or remove the icon. The remove icon option is often denoted by a trashcan.
Now swipe your finger to the remove icon option, moving the selected icon to it and the interface should change again. It will either animate the trashcan or make it glow to show that you can lift your finger.
Once the icon is on the remove option (or trashcan) you can lift your finger and the icon will be discarded. You can repeat this exercise for all icons you wish to remove from a home screen.
