Currently, I chilling on the sofa with 2 of my labradors keeping me company, while my other labrador has stretched out on the other sofa.
I have my Samsung Note 4 somewhere nearby (not sure exactly where) but by using Samsung’s SideSync app and multitasking I can operate my Note 4 completely. I’ve sent messages using 5 different messaging apps from my Note 4 but using the Tab S.
Above you can see the phone overlayed but you can minimise as required to a little circle which sits on top of whatever app your using. You can bring it back instantly. You’re also notified on the Tab S of any notifications and more. You can control the Note 4 totally seeing exactly what you are doing too.
I also transferred some photos between the devices instantly.
