One of the most interesting rumours to have surfaced about the upcoming iPhone 15 range is the including of solid state buttons for volume and power. Instead of having a physical button, a haptic feedback engine will register touch as a button press – similar to how the home button works on the iPhone SE.
It's a cool concept. Removing physical buttons should reduce the number of places where water and dirt can get into the handset, improving its durability. But it does pose some interesting challenges. On the current models with physical buttons, various long-presses can enable features like turning the phone on and off, resetting the device or making Emergency Calls – you know, the important stuff.
