Uninstalling an app
If you no longer need an app that you've downloaded and installed, you can uninstall
it.
Most of the preloaded apps cannot be uninstalled.
From the Apps screen, press and hold the app you want to remove, and then drag it
to Uninstall.
If you purchased an app in Play Store, you can uninstall it for a refund within a
limited time. To know more about the refund policy for paid apps, refer to the
Google Play help.
