The case/holder shown in black is what attaches to the lens. Screwed onto the lens, my only issue is the holder started breaking at the corners when I would take my note 2 out of the case

I don't know the size of the Galaxy S4, because this has a hard case that fits the Gallaxy Note II.Your phone fits into the case and you screw the lens on the phone through the hard case. If the Galaxy S4 is the same size as the Gallaxy Note II then it will fit. I just went on Amazon and clicked on cell phone accessories and entered Gallaxy S4 accessories and found one for your phone for just $24 bucks.

The lens is compatible with any phone, but you need the case that fits your particular phone to attach the lens to it.

If the samsung galaxy s4 has the option of "bluetooth" then you will be able to use it with it.

I have a Samsung Galaxy S3 so I can't answer if it works with the S4. Perhaps you could send the same question to the Samsung forum on Samsung's USA website.

Yes it works fine with the S4, and yes a wall charger is included. As a side note it will not work with most cases, it pretty much holds just the phone.

It works well with my Nexus 5, and has room to spare. I think it would work fine with the S4 since it isn't much bigger than the Nexus.

I don't believe it should be any different. It's compatible in general for all Galaxy S4 models.

So long as your phone supports Bluetooth 2.1 (which the S4 does) it should work just fine.

Shows compatible with ANY smart phone, the BlueAnt is on Nokia's compatible list! It is compatible with my new Samsung Galaxy S4. Works great:)

Yes it is compatible with the galaxy S4.....however using the phone continuously while charging is not recommended as it will drain both phone battery and the batteries in the charger unit its best not to or limit use of the phobe during use of the charger.

I have no idea since I do not own a Galaxy S4. I only tested it with Nexus 4 and 5. Sorry I could not help you.
