A leaked slide has been obtained recently which is claimed to belong to a Samsung Presentation about the upcoming Galaxy S8.
The Korean company has planned to introduce a Continuum like functionality to Android. This is a great feature that converts your phone into a PC when it is connected to a monitor, keyboard or mouse.
This concept is well appreciated by Samsung and most probably will be included in the Samsung S8. The phone will be connected through a cable. Bluetooth is the other option with which keyboard and the mouse can be connected.
This feature will provide added workspace, a wholesome desktop experience and an addition window for muti-tasking. This leak may not be 100% sure but it will be a great feature for sure if developed.
