Smartphone design has changed a lot over the years. Slide-out keyboards and headphone jacks have been discarded for sleek, slim designs. We’ve also seen the number of buttons get chopped down, and I think that needs to change.
The typical modern smartphone has three buttons—Volume Up, Volume Down, and Power. There are some exceptions, of course—like the iPhone SE—but the vast majority of phones follow this design. There are some practical reasons for this, but I miss buttons.

Where Did the Buttons Go?

Smartphones used to have a lot more moving parts. There were slide-out keyboards, swiveling displays, trackballs, and, of course, buttons. At one point, most Android devices had a whopping four navigational buttons.
As time has gone on, many of these features have been abandoned. It’s very rare to see phones with physical keyboards and buttons for navigation. A big part of the reason for that is durability, which is a good thing for you.
Moving parts have a much higher failure rate. Slide-out keyboards get loose, the keys stop working, buttons get mushy or broken, and so on. You probably know someone who had an iPhone with a broken home button. Parts that move are parts that break.
Removing these moving parts gives phones fewer failure points. The same can be said for ports, like the headphone jack. All of these things are access points for dust and water as well. A device with fewer moving parts and openings is simply much more durable.

The Case for Buttons

Technically, you don’t need any buttons on a modern smartphone. The iPhone and Android both have gesture navigation and options for controlling volume and power with the touchscreen. However, they keep those physical buttons because they’re more convenient than software.
Why are we limited to convenience for power and volume? There are plenty of other things that I would love to have the ability to do with a button press. Thankfully, at least on Android, one of those is accomplished by double-pressing the power button.
Phones all have digital assistants now, but the methods for quickly launching them aren’t great. The fastest method is to just use your voice, but what if you don’t want your phone constantly using up battery while listening for a command? Some Android phones had Google Assistant buttons and it was super handy.
What about your wallet app? That’s something you probably need to open up quickly when you’re checking out at the store or showing a ticket or boarding pass. If mobile payments are going to replace physical cards, it should be easier than pulling my wallet out of my pocket.
The point is everyone probably has apps or functions that they need to quickly access. Even just a single button that could be programmed to whatever you want would be super handy.
