The Galaxy S10 is going to be the first smartphone from Samsung to come with a display-based fingerprint sensor. We have seen this technology already on several Chinese handsets and Samsung is now jumping on the bandwagon with its next flagship. However, if you like using screen protectors on your devices, you may want to look elsewhere.
Accessory manufacturer Armadillotek makes things like screen protectors for a wide variety of devices. It will obviously be making them for the Galaxy S10 series as well. The company claims to have tested its protectors on “real” Galaxy S10 phones and says that the display-based fingerprint sensor does not work with protectors.
This will likely be cause for concern at least for some customers who wouldn’t want to use an expensive smartphone like the Galaxy S10 without additional protection for the display. The company says that the Vanguard case it ships for the Galaxy S10 will thus not feature a screen protector.
It may be possible to get a different result with screen protectors from another accessory maker. There are examples of smartphones with in-display fingerprint sensors working with protectors so all hope is not lost. This will eventually be cleared up after February 20th once Samsung officially launches the Galaxy S10 in San Francisco.
