Samsung’s infinity display is expected to be a staple design feature on future smartphone models, such as the Galaxy S9, according to the Korean publication, The Bell . Samsung may already have its 2018 flagship in development and reports indicate the Galaxy S9 and Galaxy S9+ may have the same screen size as the Galaxy S8 and Galaxy S8+ at 5.8-inches and 6.2-inches respectively.

A number of small rumors have already surfaced for the Galaxy S9, despite the fact the Galaxy Note 8 has not yet released. The device is reportedly codenamed “Star.” It may have 4nm processors, one possibly being the Qualcomm Snapdragon 845 chip, and it may also feature solid state batteries as opposed to lithium-ion batteries.

While the new rumor about the infinity display for the Galaxy S9 cannot be confirmed, it does make sense. The Galaxy S9 is expected to finally introduce Samsung’s long-rumored on-screen fingerprint sensor feature. If the feature does come to fruition on the 2018 flagship, it would likely be ideal that Samsung not make any other major changes to the display, as to not take away from the fingerprint scanner as a highlight feature.

Samsung was expected to introduce the on-screen fingerprint sensor on the Galaxy S8 in early 2017; however, the manufacturer scrapped the feature dude to developmental issues. The smartphone still released with a virtual, on-screen home button instead of a capacitive home button, but its fingerprint scanner was moved to the back panel of the device. This has been a major pain point for users due to the scanner’s odd placement to the right of the rear-camera module.

Typically, manufacturers put rear fingerprint scanners in a centered location for easy access without looking. On the Galaxy S8, it is easy for a user to accidentally touch the camera module, or simply be unable to place their finger in a position that allows for easy authentication.

Early Galaxy Note 8 rumors also suggested the device might include an on-screen fingerprint sensor. Reports now claim the feature has once again been delayed due to further technical  issues with the component. Samsung has reportedly had issues embedding the integrated chip, which would make the on-screen fingerprint scanner work. Additionally, there have been reports of a brightness imbalance on the screen where the fingerprint scanner is located.

Samsung seems to have opted for the safe yet less-than-favorable rear-fingerprint scanner, rather than risk including a feature that may not work properly, which could lead to another recall or device discontinuation. There has been no staunch confirmation that Samsung will try once again to implement its on-screen fingerprint scanner on the Galaxy S9. Pundits have assumed as such, considering rival manufacturers such as Apple and Vivo are also planning on-screen fingerprint scanners for upcoming devices.

Samsung partnered with biometrics company Synaptics for its on-screen fingerprint sensors. The company developed an optical fingerprint sensor technology, which can detect a fingerprint through  650 microns of glass. It is more than twice as sensitive to fingerprint detection than Synaptics' capacitive fingerprint sensor.

In January, Synaptics expected its fingerprint scanners would be ready for implementation in devices to be introduced in the second half of the year. However, the company isn’t the only one having trouble with its on-screen component. Reports indicate that Apple planned to use Qualcomm’s on-screen fingerprint sensor for upcoming versions of the iPhone, but the component and possibly also the device may be delayed due to production issues with the component.​
