What it’ll do is when you’re in that mode and push the button it’ll basically send the volume up command to the phone which, on the iPhone, will trigger the camera. Shutter cuz it’s the same thing as hitting the button on the side here to take a picture on Android if it supports the phone there’s a list on the Amazon cell page. With that information, I will send the Enter key. So if I switch over to my little other app here, my notepad app and hit the button, you can see it moves it down there. The only downside to it is that when you have it on, you, can’t get the on screen keyboard on your iPhone. So you just need to switch it off if you want to use a different app, but it is, bluetooth has a pretty decent range and it’s a great way to trigger your camera remotely.
