Some apps that come pre-installed (e.g., calculator, Google Play™ Store, Verizon Cloud, Call Filter, etc.) on your Android™ device can't be uninstalled; however, they can be disabled (turned off) so they don't appear in the list of apps on your device.
The option to enable o desactivar an app may only be available for apps that can't be uninstalled.
From a Home screen, swipe up then navigate: Settings > Apps.
Tap the Dropdown icon (at the top) then tap All.
Locate then tap the app name (e.g,, Cloud, calculator, etc.).
