The look of smartphones has evolved significantly over time. For elegant, thin designs, slide-out keyboards and headphone jacks have been abandoned. The amount of buttons has also been reduced, which I believe should be changed. Why Do Smartphones Require More Physical Buttons
A contemporary smartphone often includes three buttons: Volume Up, Volume Down, and Power. Of course, there are a few outliers, such as the iPhone SE, but the great majority of phones adhere to this design. This has certain practical purposes, but I miss buttons.
WHERE DID THE BUTTONS GO?
There used to be a lot more moving parts in smartphones. Slide-out keyboards, swiveling screens, trackballs, and, of course, buttons were available. Most Android handsets used to have a staggering four navigational buttons.
Many of these features have been phased down over time. Phones with physical keyboards and navigation keys are quite rare. One of the main reasons for this is durability, which is excellent for you.
The failure rate of moving parts is substantially greater. The keys on slide-out keyboards wear out, the buttons get mushy or damaged, etc. You’ve most likely met someone who has an iPhone with a broken home button. Parts that move are likely to break.
Phones with fewer moving parts have fewer failure spots. The same is true for ports such as the headphone jack. All of these things provide entry opportunities for dust and water. A gadget with fewer moving parts and apertures will simply last longer.
THE CASE FOR BUTTONS
A contemporary smartphone technically does not require any buttons. Both the iPhone and Android offer gesture navigation and touchscreen controls for volume and power. They preserve the physical buttons, though, since they are handier than software.
Why are we constrained by convenience in terms of power and volume? There are several additional things I would like to be able to perform with a single button push. Fortunately, at least on Android, one of them can be done by double-pressing the power button.
Digital assistants are already a standard feature on phones, but there aren’t many effective ways to activate them quickly. The quickest approach is to just use your voice, but what if you don’t want your phone continually draining its battery while waiting for a command? Some Android phones have Google Assistant buttons, which were quite useful.
