Samsung is yet to officially announce its next flagship smartphone but rumors and speculations have already started to pour in, giving us an idea about the Galaxy S8 smartphone. Based on the latest rumors, the next-in-line of Samsung s premium Galaxy smartphones will get rid of the home button and come with what is called as an optical fingerprint sensor. Unlike previous models where the fingerprint scanner was clubbed with the home button, the Galaxy S8 is expected to feature the scanner, which will be layered beneath the display.

Unlike the capacitive and ultrasonic fingerprint sensor, the optical fingerprint sensor is bulkier and uses 2D image instead of 3D image for recognizing fingerprints. According to a Weibo post, with the Galaxy S8, Samsung is likely to use a high-resolution sensor under the display, which will increase the screen size without making the rest of the smartphone larger in size. It will allow the smartphone maker to make more room on its display and offer an edge-to-edge experience. The flagship smartphone is further rumored to get rid of the physical home button that currently doubles up as a fingerprint scanner and instead feature the sub-screen sensor. Having such a technology will make the Galaxy S8 Samsung s first smartphone to come with a fingerprint scanner beneath the display.

For its Galaxy S8, Samsung could also place the fingerprint scanner on the back of the phone or on the side as part of the power or lock button in order to achieve a full touchscreen display. With the introduction of Xiaomi s Mi MIX concept smartphone that boasts a 6.4-inch near bezel-less display with screen-to-body ratio of 91.3 percent and instead of the metal frame, comes with a ceramic frame. The edgeless design by Xiaomi has raised the bar for other manufacturers to chase the idea of a similar bezel-less smartphone design. According to the report, Samsung is facing some issues with the components for the optical fingerprint recognition. However, given that there is still time for the official debut of Galaxy S8, it is expected that the company will overcome the production issues.
Fingerprint technologies have gradually come to become a standard in newer smartphones and manufacturers have been experimenting to get the technology right without hurting the overall design of the smartphone. Earlier this year, LG demoed a new type of sub-screen fingerprint sensor that sits under the display of a smartphone. With a 0.01-inch space cut into the underside of the smartphone cover glass, it allows manufacturers to insert the sensor without compromising on the overall design of the smartphone. LG claimed that the hidden sensor is not only fast but also accurate as compared to the traditional button type sensors.

Software giant Microsoft also patented the idea for a similar technology last month which mentioned the use of fingerprint sensors beneath the display that allow manufacturers to make their devices thinner. The Microsoft technology uses a wave guide beneath the glass along with a filter that would allow a sensor on the side of the glass to sense the fingerprint on the glass surface. The technology is claimed to be used both with LED and AMOLED screens.
Though, Qualcomm is likely to have a bigger impact with its ultrasonic fingerprint sensor. Called the Snapdragon Sense ID technology, it works through moisture or other common contaminants. It also works with glass, plastic and certain metals, allowing smartphone companies to experiment with different techniques to implement fingerprint scanner within the smartphone.
