The next Samsung flagship smartphone will not feature an in-glass fingerprint sensor as part of the touch screen as developers were unable to make it work in time, according to South Korean media.A report in the Investor quotes senior Samsung officials as saying that it will not be feasible this time, despite progress in developing in-glass sensors.”The Korean tech giant and its touch sensor partner Synaptics were running out of time”, writes the newspaper.”Samsung poured resources into Synaptics' fledgling technology last year but the results were frustrating,” a source briefed on the matter told The Investor 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.”The home button is widely expected to be relocated to the back next to the rear-facing camera lens.
