On our 2 computer systems, we have installed Norton 360 Premier installed. Can we add Android based phone as the subscription permits 3 installations (i.e. up to 3 PCs) under the same subscription? And if not, can we enhance and upgrade to Norton 360 to Norton 360 Multi-Device version?
Norton 360 is made for MS Windows based PC computer systems only, so it cannot be installed on any non-Windows device like Android phone. Besides, it is impossible to either upgrade or downgrade from one to other Norton product. In such case, Norton 360 premier subscription cannot be updated to Norton 360 Multi-device. Thus, Norton 360 Multi-Device can be obtained through a new purchase.
