We’ve been hearing rumor after rumor that eventually some manufacturer is going to release a device with a fingerprint scanner built into the glass of the display. No more buttons, just a huge screen that can handle all buttons and sensors.
We still haven’t seen that device, but the first ever optical fingerprint sensor from Synaptics brings us one step closer to actually getting a phone that’s all screen without needing to make room for a physical button anywhere on its face.
The fingerprint sensor is a technological marvel that can read a fingerprint from under 1mm of glass, including a curved glass screen. That means that instead of having to build a physical button anywhere on a device, OEMs can just stretch the screen out and use something similar to the on-screen navigation keys that we’re used to.
If this is going to make a public debut anytime next year, you can bet we’re expecting it in the Galaxy S8. We’ve heard plenty of rumors about Samsung using a bigger screen and almost completely eliminating bezels for next year’s round of flagships, and a fingerprint sensor built right into the screen sounds exactly like the last piece of the puzzle that Samsung has been waiting for.
There’s no guarantee, but it’s a very exciting possibility.
