Vivo has launched the Vivo X20 Plus UD in China, and the product page has raised a very peculiar point. It turns out that the in-display fingerprint sensor doesn’t work with screen protectors above a certain thickness; which makes buying new ones a little tricky.
The additional layer of materials seem to interfere with the Synaptics designed fingerprint sensor. Which is something that we should have expected; seeing that most fingerprint sensors are only hidden behind thin walls of plastic. We’re not entirely sure if a regular screen protector completely prevents fingerprints from being read, or if it simply reduces the accuracy of the image.
Despite this small inconvenience, Vivo is including a screen protector that will work with the sensor with every purchase of the phone. However, it also means that people looking for replacements will likely have to buy one from the company.
The X20 Plus UD (UD being Under Display) was meant to be Vivo’s big announcement at CES 2018. And it certainly was, allowing the company to get the jump on much larger manufacturers by being the first to introduce the in-display fingerprint sensor. That said, it’s a rather average device that sports mid-range specifications.
While the fingerprint sensor is the main news here, it should be noted that Vivo has also revealed that the X20 Plus UD will retail for ¥3598 (about RM2200) and will ship in China on 1 February. Just in time to catch the Chinese New Year shopping rush.
