If you're using a Sprint-branded phone and want to remove all the Sprint apps, there are a few different ways you can do it.
The first way is to use the built-in Android settings. Go to Settings > Apps, then find and tap on the Sprint app you want to uninstall. You'll see an Uninstall button at the top of the screen - tap that, and confirm when prompted.
You can also uninstall Sprint apps using a third-party app like Easy Uninstaller. Just install Easy Uninstaller from the Play Store, open it up, and find the Sprint app you want to remove. Tap on it, then hit Uninstall.
If you're rooted, you can use a root file explorer like Root Browser to delete the files associated with Sprint apps from your system partition. This is a bit more complicated than using either of the other two methods, but if you're familiar with using root tools it shouldn't be too difficult.
Whichever method you use, uninstalling Sprint apps from your Android device is relatively simple and straightforward.
