Samsung Galaxy S8 not recognised by Android Studio

Question

I am trying to use my Galaxy S8 with android studio as an external device but it seems like my Mac cannot recognize it.

• I have developer mode and USB debugging enabled
• ADB drivers are installed, but when I run ADB devices on terminal it does not display anything
• I tried to restart the ADB server several times but it does not work anyway
• I tried on a different Mac and on a Windows computer - same problem-
• I tried all the previous solutions with a different USB cable - same problem-
• I installed SmartSwitch, but also this program does not recognize my device, same for AFT, I also deleted one of the two and tried singularly, but as always, it does not work.

Basically it seems that the phone can only be charged via usb, but I have no reason to believe that the usb port might be damaged.

Answer 1

I solved this problem downloading this driver from the oficial Samsung page. After install it, the whole drivers will re-install again. Besides, make sure you have enabled the Debugging mode and try to run again. I hope this helps.

Answer 2

I had the same problem. An OTA update had turned off developer mode and I hadn't realized it.

Settings → Developer options → USB debugging → (on)

resolved it for me.

Answer 3

Me too I had same issue (Mac + samsung s8), I tried a lot of things, and then it worked :

1. Unplug your Android Device
2. Disable the USB debugging
3. Re-enable and plug (or maybe, plug and re-enable, can't remember)
