My Samsung phone was not recognized by Android Studio on windows 7. I repaired it by installing the Samung Driver here: http://developer.samsung.com/technical-doc/view.do?v=T000000117

I tested with my Galaxy S2 and the Samsung S7560 and it works now

    @matthias: my samsung seems to work fine in (mtp) mode rather than (ptp) mode. The key for me was enabling developer mode and then developer usb debugging as suggested by Edward Islam below – User Feb 26 '16 at 06:38

    the answer is not so relevant, since its a manufacturer specific question(and questioner says himself question as a solution too). – Ansal Ali Feb 16 '16 at 06:04

I had the same issue when connecting a SM-T113 to a Windows 7 PC. The problem was solved by installing Smart Switch.

I solved in following way:

    Go to Settings->Developer options-> On top of the screen, turn on the button.

Now goto bottom on the debugging section.

    Now turn on USB debugging option

It will ask some questions if you want to allow the PC to this device, press allow all time!
