While the debate still rages on between which way should major smart phone manufacturers should sway between choosing Capacitive buttons or On Screen Buttons, one thing is for sure, both of these offer advantages of their own. From our personal opinion, we prefer capacitive buttons simply because in case you end up damaging your display bad of your device, at least your buttons still work, which may not happen with on screen buttons.
However, with Capacitive buttons, there is very little customizations you can do. Like you cannot play around with the brightness of the button. HTC has notoriously been the major manufacturer that has used Capacitive buttons in all it’s flagships recently. We have seen with HTC One X, HTC One X+, HTC One, HTC One S all sport capacitive buttons. However, a developer over XDA has come up with an app that can play around with the brightness of the capacitive button. You can select between three stages of dim, bright and off.
You need to have a rooted HTC device for the app to work. The application currently supports the HTC One X, HTC One X+, HTC One and HTC One S, but there have been users who have reported the app works very well with likes of HTC One V too. If you would like to try it out, then you can download the application for free from the XDA Forum here.
