Android Studio doesn't recognize my device

Question

Here is the problem. I want to run my Android Studio apps on my device (Samsung Galaxy Ace 2). But nothing works for me. Tell me what I\'ve missed:

1) USB debugging

Answer 1

I was on Samsung S8 and had same problem too. After I installed Samsung Kies, issues was resolved for me, as I believe it had updated the correct driver required for my Samsung S8.
