When Apple introduced its new iPad Air, which has Touch ID built into the top button, I was hopeful that the company would bring its fingerprint-scanning tech back to the iPhone, too.Unfortunately, that wasn't the case with the iPhone 12. Like every modern iPhone with a borderless, edge-to-edge screen, the iPhone 12 lineup only supports Face ID when it comes to biometric authentication.At a time when I find myself typing in my passcode more than ever because I'm wearing a mask, it would have been nice to see Apple re-introduce Touch ID to the iPhone.Some Android phones like the Samsung Galaxy S20, Galaxy Note 20, and OnePlus 8 Pro offer both fingerprint detection and face unlock. Google's new Pixel 5 also has a fingerprint sensor, although it lacks facial recognition.The Apple Watch has had an always-on display since the Series 5 model debuted last year, but we have yet to see this feature on the iPhone.Android phones like the Galaxy S20, Galaxy Note 20, and Google Pixel 5 have displays that can show information like the time, date, battery level, and unread notifications even when the display is turned off. That can make it easier to see information at a glance without having to reach for your phone.In my experience, having an always-on display has made it easier to check the time or see which app a notification came from without falling down the rabbit hole of scrolling through Instagram or my overflowing email inbox.The iPhone 12 may not have an always-on display, but Apple did improve the iPhone's screen in a couple of other ways, such as by making OLED screens standard across all models and improving their durability with a new ceramic shield coating. A number of Android phones such as those from Samsung, Google, and OnePlus also have screens that are capable of reaching a higher refresh rate for smoother scrolling. Phones like the Galaxy S20 lineup, Galaxy Note 20 Ultra, and OnePlus 8 Pro can increase their screens' refresh rates up to 120Hz, compared to the 60Hz refresh rate that's considered average on smartphones. The ability to crank up the refresh rate can make navigating the phone's software feel faster, more responsive, and more fluid, although that can also mean compromising when it comes to resolution. This feature isn't available on the iPhone, but Apple does offer it elsewhere: on the iPad Pro. Apple's high-end tablet has a feature called ProMotion, which boosts the screen's refresh rate up to 120Hz, a capability that Apple has touted as being ideal for use with the Apple Pencil.
