What Is an Android Launcher?
If you have ever installed an app that offered to become your "home app," you have met an Android launcher. Launchers are one of the things that make Android so customizable, but they can also be confusing. This guide explains what a launcher is, what it can and cannot change, how to pick one as your default, and how to go back if you change your mind.
What a launcher does
A launcher is the app that shows your home screen. It is what you see when you unlock your phone or press the Home button, and it is responsible for things like:
- The layout of your home screen pages, including app icons, folders, and widgets.
- The app drawer, the list of all your installed apps, usually opened by swiping up.
- Your wallpaper display and how icons look, including icon shapes and sizes.
- Home screen gestures, such as swiping down for notifications or double-tapping to lock.
- Extras some launchers add, like a search bar, a news feed, weather, or quick-access tools.
Every Android phone comes with a launcher already installed. Samsung phones use One UI Home, Pixel phones use the Pixel Launcher, and other brands have their own. These built-in launchers are perfectly good, but you can replace them with another launcher from the Play Store if you want a different look or extra features.
What a launcher does not change
This is the most important point for many people: a launcher changes how you get to your apps, not the apps themselves. When you switch launchers:
- Your apps stay installed. Nothing is deleted or reinstalled.
- Your data stays where it is. Photos, messages, contacts, accounts, and files are not affected.
- Your settings stay the same. Wi-Fi, Bluetooth, notifications, and the Settings app work as before.
- Your phone's software is not modified. A launcher is a regular app; it does not change the operating system.
What may change is the arrangement of your home screen. A new launcher usually starts with its own layout, so your icons and widgets may be in different places. Some launchers can import your previous layout, but many cannot. Your original layout is typically still saved in the old launcher, so it reappears when you switch back.
Also note that some parts of the interface, such as the notification shade, Quick Settings, and on many phones the Recents screen, belong to the system rather than the launcher, so they may look the same no matter which launcher you use.
How to set a launcher as your default
When you install a new launcher and press the Home button, Android may ask which app to use, or the launcher may guide you to the right setting. You can also change it manually at any time. Menu names vary by manufacturer and Android version, but the setting is usually called Home app.
Pixel and most Android phones
- Open Settings.
- Tap Apps.
- Tap Default apps.
- Tap Home app and choose the launcher you want.
Samsung Galaxy phones
- Open Settings.
- Tap Apps.
- Tap Choose default apps (called Default apps on some versions).
- Tap Home app and select the launcher.
If you cannot find it, type "home app" or "default apps" into the search bar at the top of the Settings app.
How to switch back
Changing your mind is easy and safe. Follow the same steps above and select your phone's original launcher, such as One UI Home or Pixel Launcher. Your previous home screen layout should return as you left it.
You can also simply uninstall the third-party launcher. Open Settings > Apps, find the launcher, and tap Uninstall. Android automatically goes back to the built-in launcher, or asks you to choose one. You cannot uninstall the phone's built-in launcher, so there is always a home screen to fall back on.
If a launcher is not working properly
If a launcher freezes or keeps crashing, you can usually still reach Settings by swiping down from the top of the screen and tapping the gear icon in Quick Settings. From there, change the Home app as described above. Starting the phone in safe mode also temporarily switches to the built-in launcher, since safe mode disables downloaded apps.
What permissions do launchers need?
A launcher needs to see which apps are installed so it can display them, which Android allows as part of its role as a home app. Beyond that, many launchers work with few or no special permissions. Depending on its features, a launcher may ask for:
- Notification access, to show notification dots or counts on app icons.
- Location, to show local weather on the home screen.
- Contacts, to include people in home screen search results.
- Usage access, to suggest apps you use often.
- Calendar, for calendar widgets or agenda views.
A good rule: a permission should match a feature you actually use. Android lets you decline most permission requests and still use the app; the related feature simply will not work. You can review and change permissions at any time in Settings > Apps, by selecting the launcher and tapping Permissions.
Be cautious if a launcher asks for sensitive access that has no clear connection to a home screen, such as reading text messages or making phone calls, unless it clearly explains why. Install launchers from trusted stores, read recent reviews, and check the developer's privacy policy.
Why people use a different launcher
People choose alternative launchers for many reasons: a cleaner or simpler look, larger icons that are easier to see, more control over the grid and gestures, or quick access to tools like a flashlight or volume controls right on the home screen. Some launchers are designed for older adults or children, with big buttons and limited options. Others focus on speed and minimalism.
Because switching is reversible and does not touch your data, trying a launcher is a low-risk way to make your phone feel new. If it does not suit you, switching back takes less than a minute.
