Now that all the alleged vital details of the upcoming Galaxy S10 series have been leaked, it seems we will be getting the narrower information in the coming days, before the phones are launched on February 20. The latest string of info comes from the accessory retailer MobileFun, who has shared a video of the Galaxy S10 Plus to show off its protector. In the process, the accessories seller has revealed an annoying limitation of the Galaxy S10 Plus as well as the Galaxy S10, as both the phones are tipped to come with a similar display and in-screen scanner.

In the video shared by the retailer, we get to see the in-display scanner of the Galaxy S10 Plus in action. The clip shows that the screen protector has a large, unsightly circular cutout towards the bottom to enable users to unlock the phone. This reveals two limitations of the phone; one that it will have a minimal active fingerprint recognition area. Where other manufacturers are attempted to incorporate a significant part of the display with a scanner, having a minuscule portion will only complicate things when authenticating yourself.
