Being that it's a new phone, you can safely do a factory reset. I've provided the instructions below on how to do so. Remember to remove your memory card if any is inserted:
A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIM card or SD card.
If the device menus are frozen or unresponsive, you can master reset using hardware keys.
- Back up data on the internal memory.
- Turn off the device.
- Press and hold the Volume Up key and the Home key, then press and hold the Power key.
- When the Samsung Galaxy Note5 logo screen displays, release only the Power key
- When the Android logo displays, release the Volume Up and the Home key ('Installing system update' will show for about 30 - 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times key to highlight 'wipe data / factory reset.'
- Press Power button to select.
- Press the Volume down key until 'Yes -- delete all user data' is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, 'Reboot system now' is highlighted.
- Press the Power key to restart the device.
That should fix that problem, sometimes preinstalled apps from the carrier can prevent some of the Google services from running.
