Why Samsung Ditched On-Screen Fingerprint Scanning For Galaxy S8 (theinvestor.co.kr)
An anonymous reader shares a report: Samsung Electronics' upcoming Galaxy S8 is unlikely to feature on-screen fingerprint scanning after its touch sensor partner Synaptics ran out of time for developing the related technology, industry sources told The Investor earlier this month. On-screen fingerprint was a highly anticipated function for the new phone with a larger-than-ever display screen. "Samsung poured resources into Synaptics' fledgling technology last year but the results were frustrating," a source briefed on the matter on condition of anonymity. "With the production imminent, the company had to decide to relocate the fingerprint scanning home button to the back of the device at the last minute." A larger screen that covers almost the entire front body is a key feature for the S8. Since last year, Samsung had made all-out efforts to embed a fingerprint scanner under the display to allow users to unlock the phone by placing their finger on the screen, not the physical home button on the bottom.
Grip around sides.. index finger rests right in middle, where the scanner is. The only time that doesn't apply is when holding landscape style.
When gripping the phone to activate frontal fingerprint readers you actually need to let the phone hang loose a bit to get the thumb onto the reader, which is problematic on large format phones. I have an iPhone 7 and an LG V20. The V20 is more natural to hold and activate.
