What blocking an app actually does

Blocking an app in Android stops it from running in the background, receiving notifications, and using your phone's resources — but it does not uninstall it. The app stays on your phone taking up storage space. If you block an app and later change your mind, you can unblock it with a few taps. Blocking is useful when you want to stop an app from bothering you without losing it entirely, or when you want to prevent a child from opening a particular app.

Android gives you several ways to block apps depending on what you want to stop: background activity, notifications, or access altogether. Each method works differently and gives you different levels of control.

Key Takeaways

  • Blocking an app stops it from running in the background and sending notifications, but does not remove it from your phone.
  • You can block notifications from a single app by opening Settings, finding Apps, selecting the app, and toggling off notifications.
  • To prevent an app from running in the background, go to Settings, Battery, and add the app to the restricted list.
  • Parental controls in Google Play let you set a PIN and restrict which apps a child can open, which is stronger than blocking.
  • Disabling an app removes it from your home screen and stops all its functions, but you can re-enable it later from Settings.

Blocking notifications from a specific app

This is the fastest method if an app keeps sending you alerts you do not want. Open Settings on your Android phone, then tap Apps (or process Manager on older phones). Scroll through the list until you find the app you want to block, then tap it. Look for a Notifications option — on most phones this appears as a toggle switch. Turn it off.

Some apps have more detailed notification controls. After you tap the app name in Settings, you might see options like "Allow notifications" or a list of notification types. You can turn off all notifications or just silence specific kinds — for example, you might block promotional notifications but keep order updates. The exact wording and location varies by phone manufacturer, but the principle is the same: find the app in Settings and look for the Notifications toggle.

Stopping an app from running in the background

Apps that run in the background drain your battery and use your data even when you are not actively using them. To stop this, open Settings and look for Battery or Battery and Device Care (Samsung phones use this name). Tap Battery Usage or a similar option. You will see a list of apps ranked by how much battery they use. Find the app you want to restrict and tap it, then look for a button that says "Restrict," "Restrict app," or "Put to sleep."

On some Android phones, you can also restrict background activity through Settings > Apps > [App Name] > Battery. Look for an option called "Battery optimization" or "Background restriction" and set it to Restricted. Be aware that restricting an app in the background may prevent it from working properly — for example, a messaging app might not receive new messages until you open it manually. Test the app after restricting it to make sure it still does what you need.

Disabling an app completely

Disabling an app is stronger than blocking notifications or background activity. It removes the app from your home screen and stops it from running at all, though the app files remain on your phone. Open Settings, go to Apps, find the app you want to disable, and tap it. Look for a button that says "Disable" — you may need to tap a menu icon (three dots) to find it. The phone will ask you to confirm.

Some apps cannot be disabled because Android or your phone manufacturer considers them essential. If you do not see a Disable button, the app is locked and you cannot turn it off this way. You can still block its notifications and background activity using the methods above. If you disable an app and later want to use it again, go back to Settings > Apps, find the app, and tap Enable.

Using parental controls to block apps for a child

If you want to prevent someone else from opening an app, parental controls are more effective than blocking. Open Google Play Store, tap your profile icon in the top right, then tap Settings. Scroll down to Family and tap Parental Controls. Turn on the toggle, then set a PIN that only you know. Choose the content type you want to restrict — Apps & Games is what you need to block specific apps.

After you set the PIN, go back to the home screen and open Google Play Store again. Search for the app you want to block, open it, and look for a menu icon (three dots). Tap "Restrict this app" or similar wording. The app will be hidden from the Play Store and cannot be opened without entering your PIN. This method works only for apps installed through Google Play Store, not for apps that came pre-installed on the phone or installed from other sources.

Unblocking or re-enabling an app

If you blocked notifications, go back to Settings > Apps > [App Name] and toggle notifications back on. If you restricted background activity, open Settings > Battery, find the app in the restricted list, and remove it or change the setting to Unrestricted. If you disabled the app entirely, go to Settings > Apps, find it in the list, and tap Enable.

For parental controls, open Google Play Store, go to your profile > Settings > Family > Parental Controls, enter your PIN, and tap the app you want to unrestrict. The app will become available again. If you forgot your parental control PIN, you will need to remove your Google account from the phone and add it back, which erases all data — contact Google Support for help with this.

When to block versus when to uninstall

Block an app when you might want to use it later but do not want it bothering you right now. Uninstall an app when you are certain you will not use it again and want to free up storage space. Blocking takes seconds and is reversible; uninstalling also removes the app from your phone entirely. If an app is using too much battery or data, blocking its background activity is often enough — you do not need to uninstall it.

If an app is broken or behaving strangely, try disabling it first rather than uninstalling. Disabling removes it from your home screen and stops it from running, but you can re-enable it if you change your mind. Uninstalling deletes all the app's files, and if you want it back later you have to read it again from Google Play Store.

Frequently Asked Questions

Can I block an app without the person who uses the phone knowing?

Blocking notifications or background activity is invisible to the user — they will not see any change unless they look in Settings. Disabling an app removes it from the home screen, so they will notice. Parental controls are also visible because the app disappears from Google Play Store. If you want to hide something, parental controls with a PIN are the most effective method.

Will blocking an app free up storage space on my phone?

No. Blocking, disabling, and restricting background activity all leave the app files on your phone. Only uninstalling removes the app and frees up space. If your phone is running low on storage, uninstall apps you do not use rather than blocking them.

What happens if I block an app that came pre-installed on my phone?

You can block notifications and restrict background activity for any app, including pre-installed ones. You may not be able to disable some system apps because Android needs them to run. If you cannot find a Disable button, use the notification and background restriction methods instead.

Can I block multiple apps at once?

Android does not have a bulk-blocking feature. You have to block each app individually by going to Settings > Apps and changing the settings for each one. If you want to block many apps for a child, parental controls in Google Play Store are faster because you can restrict multiple apps from one menu.

If I block an app, will it still use my data?

If you only block notifications, the app can still use data in the background. To stop data use, you need to restrict background activity or disable the app entirely. Go to Settings > Apps > [App Name] > Permissions and turn off Mobile Data, or use the background restriction method described above.
