Sometimes, an app annoyingly doesn’t allow you to disable its notifications in the app’s settings. Sometimes, an app even gives advertisements through the notifications, which is even more annoying. If you have Jelly Bean 4.1 or higher, you can fortunately disable almost any app’s notifications straight from the device settings. After the break are instructions on how you can get rid of the pesky alerts.
(An alternate way to get to “App info” without waiting for the notification to appear is by heading to your device’s settings menu. Under the “Device” heading, tap “Application Manager” and select the app causing the problematic alerts.)
2. Once you get to “App info,” you should see a check box with “Show notifications” checked.
3. All you need to do is tap on the box to uncheck “Show notifications”, tap “OK” in the warning popup, and you are good to go. No more notifications!
You can always re-enable the notifications by going back into the settings and rechecking the “Show notifications” box.
