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 or disable 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.).
