[Q] Hello, just a couple questions. topic

Hello, i've just got a couple questions about Android itself and a device I recently bought.

Today I got a Samsung Galaxy Tab S 10.5 for the sole purpose of using it for study, I also bought a case/keyboard it. I also have a Samsung Galaxy S4 LTE-A. I'm wondering if there's a way for the two devices to "talk" together at all. I am also wondering on the tablet how to get rid of the "Quick Connect" option which is next to "S Finder" in the pull down menu from the top of the screen. I'm still somewhat new to Android, so any general tips would be great too. I've removed some bloatware from both of my android devices themselves, such as all of the Samsung pre-installed software.

Also any recommended apps too would be great and also some tips on how to use my tablet and get the most out of it. I've been a desktop computer person my whole life and I've built a few too, I just felt like a new change and I want to make the most out of it. I apologise if this is the wrong area to post in, it's just I have no idea where to ask for help.

Thanks.
