If there was any air between the screen and glass then the sensor would lose or distort the sound waves, resulting in a locked phone.ĮIGER 3D Glass for Samsung Galaxy S10 Premium Tempered Glass Screen Protector This ensured a non-loss connection between the device screen and the glass. When the S10 range, featuring the Ultrasonic fingerprint scanner, was first released, we were able to make our 3D Glass screen protector compatible through an access hole in the screen protector, with a small piece of circular protective film inserted in its place. ![]() This allows the 3D glass to be used with all types of cases to ensure optimal fit and no lifting.Īvailable for : S10, S10+, S10 5G, S20, S20+, S20 Ultra, S21 UltraĮIGER 3D Glass for Samsung Galaxy S20 Ultra Case Friendly Premium Tempered Glass Screen Protector However, since the launch of 3D Glass, Case Friendly 3D Glass has been developed for ultra-curved devices by featuring a slightly smaller cut. Unfortunately, with certain Samsung models which feature a curved screen, the protector isn’t case compatible. The EIGER 3D Glass Screen Protectors offer the same high-quality materials and protection as the standard Glass range but use a special process, enabling them to be curved to match the device’s screen they are protecting. These products are case friendly, which means you can also protect the sides and back of your smartphone.ĮIGER 2.5D Glass for Samsung Galaxy S21 Premium Tempered Glass Screen Protector in CLEAR with Cleaning Kit 3D Glass – Ultrasonic Scanner This means that the product only covers the flat area of your screen. The purpose of this is to make the edge of the glass feel smooth. There is a slight curvature at the edge of a 2.5D glass display. 2.5D Glass – Ultrasonic ScannerĮIGER 2.5D Glass screen protectors are crafted from premium tempered glass and deliver maximum scratch and shock protection for your device. Our EIGER screen protector range contains two product to choose from, the 2.5D Glass or 3D Glass. We want to ensure that you are able to use the ultrasonic fingerprint scanner without compromising the protection of your smartphone’s screen. Are these technologies compatible with EIGER products? This revolutionary feature is available on the Galaxy S10, S10+, S10 5G, S10e, S20, S20+, S20 Ultra, S21, S21+, S21 Ultra, Note10, and Note10+. Samsung’s recent and most desirable series, the Galaxy S21, due to the refreshed design, updated hardware and more reasonable price (£200 less than previous series), includes the ultrasonic fingerprint technology. ![]() Since then, Samsung appears to have continued to feature this technology in their premium smartphones. The ultrasonic authentication feature first appeared on the Galaxy S10 series. Samsung’s inclusion of ultrasonic technology On the other hand, they can be frustrating to use if there is oil or dirt on the print or the glass is dirty. This potentially means ultrasonic fingerprint scanners are more reliable, and even usable when users fingers are wet. In contrast, ultrasonic sensors can create a three-dimensional image. It is the opinion of many that ultrasonic fingerprint scanners are superior as optical scanners can only form an 2D image of the visible lines on fingertips. ![]() What is an Ultrasonic Fingerprint scanner?īuilt into the screen, the Ultrasonic Fingerprint scanner is a new biometric authentication feature that sends ultrasonic pules to detect the 3D ridges and valleys of each unique fingerprint to quickly and correctly recognise users. ![]() This photograph is then used to match the print to a stored print on the phone. This technique relies on capturing an optical image - essentially a photograph, and analysing the lightest and darkest areas, to detect unique patterns such as ridges or marks. Optical fingerprint scanners are the traditional method of capturing and comparing fingerprints. In this article, we will discuss the difference between Optical and Ultrasonic fingerprint scanners, which is better, what Samsung have done to incorporate the technology in their products, and how we at EIGER have made our screen protectors compatible. Did you know that there are more than one type of fingerprint scanner technology? And that the type of fingerprint scanner your smartphone features will have an impact on which screen protectors are compatible?
