Those black twin sensor dots above your display on your phone may finally be going away

You see those black dots to the right or left of your selfie camera.Those tiny noticeable dots have been an unavoidable part of smartphone design for the better part of decade. And they might finally be going away.
Those dots are your phone's proximity sensors. Their presence means the phone can detect  when the user is holding the device up to their face to make a call. The sensors tell the phone to dim the screen when that happens, ensuring your cheek doesn't accidentally hang up on someone as you press the phone to your face. Elliptic Labs claims to have created. The Oslo-based startup has developed a way to turn the phone's built-in microphone and earpiece into an ultrasonic proximity sensor, meaning those extra black dots on the front of our smartphones could be scrubbed away permanently.
"You have to have these holes on your device, and [manufacturers] are trying to make their devices symmetric and having a difficult time," says Laila Danielsen, CEO of Elliptic. "We are using ultrasound, and we're using the current components that you have in phone."
