The Smart Key is something i use a lot on this phone, but the customization is not too useful. I mean some of the features are very useful, but that is just some of them such as open the camera app, use flashlight, screenshot. The rest of them are pretty useless in my opinion.
1: Why can i only use the flashlight on the double-press fuction and not on the press and hold or just short press function?
2: It would be cool if more features were added such as being able to return the camera to its position when its not, flashlight on press, double-press and press and hold, switch NFC on or off and more features that you can do in the tab where you swipe down from the top of the screen.
You get my point, it would make the button as useful as is can be.
