Fingerprint Sensor on the Back
Smartphones today use in-display fingerprint sensors, either optical or ultrasonic.
It’s fast, simple, and easy.
A side-mounted capacitive fingerprint sensor like the one on the Asus Zenfone 9 can also achieve the same result.

It’s slow and not as intuitive.
Headphone Jack
We’re still mad that Apple convinced the whole tech industry to kill headphone jacks.
After all, you don’t want to have to carry an adapter everywhere you go.

Notification LEDs
Notification LEDs were a simple but useful feature that modern phones don’t have.
With expandable storage, you could simply buy a new microSD card if you needed more storage.
The feature allowed you to physically squeeze the sides of your machine to perform actions.
Fitting pressure-sensitive panels may have taken valuable space that could otherwise be used to fit a bigger battery.
Front-Facing Speakers
Front-facing speakers are also going extinct.
After all, most people would rather have a bigger screen over better speakers.
Other times, they are discontinued simply because doing so is somehow more profitable for the tech industry.
For instance, front-facing speakers and notification LEDs had to go because people would rather have a bigger screen.
