We already know that the Korean company Samsung plans to update the vast majority of its most cutting-edge equipment to Android 5.0 Lollipop , the latest version of Google's operating system that is already coming to its current flagship, the Samsung Galaxy S5 . We still do not have accurate data on the arrival of the rest of the updates, but the truth is that everything indicates that the Korean is working fully on the launch of this data package for its main phones. Its roadmap includes equipment such as the Samsung Galaxy Note 4, Samsung Galaxy Note Edge, Samsung Galaxy Note 3 or Samsung Galaxy S4, among others.
