I see there are some similar questions(you may check the links below) but none of them answers my question. I have installed Android Studio many times and used 2 different phones before. 3 days ago I had to factory reset my PC and than I reinstalled Android Studio. I connected my Galaxy S4 but adb doesn't see it. BUT MY QUESTION IS before this occasion whenever I plug in a device it was sending me an USB debugging authorization code. This time it doesn't happen. Why I don't receive an authorization code ?

Here's some similar questions which helped none. Yes I almost have the same problem but one says AS starts project with virtual device other says I see my device is running but it doesn't work.

Android Studio doesn't see device

Android studio doesn't list my phone under "Choose Device"

Android Studio doesn't start with connected device

Also I did a google research found something about Google USB Driver which is already installed on my SDK. So it didn't help me either. Here's the link:

http://developer.android.com/sdk/win-usb.html

So I am hopeless. I tried everything. ADB doesn't see my device. But my real question is before you downgrade or say it is duplicate why I don't receive an USB debugging authorization code? Thanks for checking! If you could help me I would very appreciate it!

The Google USB-Driver is for Nexus devices only.

If you want to use a Samsung device you need to download and install the needed driver. A list of all supported retailers can be found here.

After you've downloaded the driver simply install it as described here.

Then you can activate the "USB debugging" mode on your device. It can be found under "developer options". If you don't see this category simply tap the "build number field" 7 times.

You need restart android device, android ADB. After that, reconnect android device to PC, it will be automaticaly installed proper USB driver.
