As magical as fingerprints may sound on displays or FoDs, they do not differ so much from their traditional optical sensor counterparts. They are practically just cameras and the real magic is more in the display that lets the light through. However, not all FoDs are the same, and the first attempt by OnePlus deserves a closer look. Zack Nelson dives into the OnePlus 6T to uncover his secrets, and determines how it might be good for future selfie cameras under the screen.
Since Nelson has already removed the back and battery when he made the OnePlus 6T transparent mod, the process is the second time easier. The only things that hold him back are really just the number of commercially available Phillips screws. A look inside shows two things that are disappointing but not unexpected for the price of the smartphone.
First, there is no tempo or heat pipe in the OnePlus 6T unlike many high-end smartphones. Since the smartphone still has the same high-end specifications, we can only hope that this cost-cutting measure will not lead to overheating of the devices. However, there have been no such incidents at OnePlus so far, even if the proprietary DASH Charge fast charging technology was used.
The inside of the OnePlus 6T also has no room for a headphone jack. At least the company was not joking when it claimed it had used up every available space for things like a bigger battery and the FoD. It is a sad day for some, but also an opportunity to grab one of the new Bullet headphones from OnePlus.
And finally we come to the fingerprint scanner itself. Contrary to what you might have expected, the sensor is completely disconnected from the display and this can even work without this feature. The light from the screen does not bleed into the opening when the sensor has been removed, and only goes in the direction of the user. This could, Nelson said, give us hope that we are not far from a future where screens have no f-stops and even the front-facing camera would hide under a virtually invisible hole in the screen.
