I have a galaxy note 3 and it works fine. However I did not like it.The volume was not acceptable at all.and I have perfect hearing.

wish I could answer you but I have an IPhone. IT works excellent with that. I would think that the Galaxy S4 would work the same...just my thoughts.Good luck..I really like this unit...GREAT!

It works well with my Samsung S4 and therefore it should work fine with the Samsung S3.

It was able to pair with my Galaxy S3 smartphone without a problem. It also uses a micro usb plug to charge so most of the same cables can be used.

As long as your galaxy S relay 4g has a MHL output, this adapter will work.

I have a galaxy note 3 and HTC One and they both work without problems so I don't think you should have any problems with connecting your Galaxy S4.

I would check the WeMo website to see if your particular SmartPhone is supported.

Galaxy s4 is base on Android 4.2, so it is compatible with this keyboard, please enjoy it without worry.

It's Bluetooth compatible so I would think it will work just fine with most if not all smartphones.
