My PC doesn't recognize my galaxy note 4. But it did when I purchased it. My questions is just as titled.
When I got my new galaxy note 4 last month, I connected it to my PC and my PC showed my new note 4 so I was able to add video files.
But now  I connected my note 4 again to my PC to store all data from cell to PC cause it's full, my PC doesn't recognizes note 4. What should I do?
2 options , both worked for Me when i had the Same issue:

If u use your fingerprintscanner , make sure you unlock your Phone After plugging it in

Second is to try Samsungs Software Kies and follow the programs instructions
