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.

You always have a finger in the back of the phone so you don't have to move a finger at all to unlock the phone and although it seemed like a small thing it really did help tremendously. Again I hated the Pixel, but I couldn't agree more with the sensor placement. Also I don't know about anyone else but after trying out 2 Samsung phones with fingerprint I have to say it has a serious issue with sensitivity as well which results in a lot more misses when trying to unlock than the Pixel.

      Because for the most part, the only time you use the fingerprint scanner is to unlock your phone.

      The point of the fingerprint reader is not for security, but for convenience.

      Apple found a LOT of people did not put even a 4-digit PIN on their phones. Why? Because the users found it too inconvenient. And the average use case bears this out - a phone is interacted with hundreds to thousands of times a day, and each interaction lasts only a few seconds - either to glance at a message, check out information, etc. For these uses, entering a PIN takes a few MORE seconds, easily doubling the interaction time.

      Instead of grouping interactions together so one unlock you do many things, Apple discovered users were simply disabling the locks so they didn't have to bother with the PIN codes that delayed the interactions. Thus, it ended up with something like 75% of all phones, despite having the capability for locking access down, were left in the open state.

      Hence the fingerprint reader - it allowed the user to put on a lock on their phone, but also allow a quick unlock for interactions.

      A fingerprint is not secure - even Apple treats it as such, which is why the fingerprint is disabled after several invalid tries (use other authentication method, like PIN), after a reboot, or after 48 hours. It's there to provide the user with a convenient way to unlock their phone, as well as having it locked down so it's not so inconvenient.
