Review on Get The Perfect Shot With CapGrip II Smartphone Camera Holder & Remote Control – Ideal For IPhones, Samsung, Google & Android Phones! by Ronnie Cole

Makes one-handed use of camera phone simpler & more steady. As someone who grew up with traditional cameras, the grip feels comfortable. Pairing was simple. My first few presses of the shutter button didn't work, but after that everything was fine.The printed instructions are tiny and not especially clear, but it's simple to figure things out, assuming you've connected Bluetooth devices before. One tip not mentioned in that material: when seating the button module (e.g., after charging), be sure the two small pins are fully seated in their matching holes. Doing that solved my initial problem with the button.
