Norton Security needed?

I have Norton Security with multi-license and deciding if I should install my last license in a Samsung Galaxy S7 cellphone or Samsung Galaxy Tab tablet.

Samsung Galaxy S7 has a in-built security feature, powered by Intel Security, it can scan and detect threats (see photo below). The Samsung Galaxy Tab tablet does not have such a security feature.

Is this Samsung Galaxy S7 in-built security feature good enough for protection? Do I still need to install Norton Security on the Samsung Galaxy S7 if the device comes with this in-built security feature from Intel Security?
