Samsung

What is it? A new "phablet" for the Galaxy Note range which has the same 5.7-inch screen as its predecessor. What can it do?

Plus Samsung continues to improve screen quality and offer a content and services bundle," he said. "It's a solid update. But there is little in the Note 4 which will change the trajectory of Galaxy Note shipments."
