Change icons with an application
Sometimes, you may not want to download a new Launcher just to change the icon pack. If this is your case, then you can download an icon changer application.

Step 1. Download Awesome icons (free with in-app purchases) from the Play Store.
Step 2. Open the application and select the application you want to create the shortcut with a custom icon.
Step 3. Tap the icon to go the settings of your shortcut.
Step 4. Now click on the icon in "icon" and choose the desired icon. If you wish, you can even change the name for the shortcut.
Step 5. Click on "OK" to create the shortcut.
