Synaptics' newest fingerprint sensor, scheduled for mass production in Q3 2017, can detect force, swipe gestures, and supports software navigation buttons

Context & Ripple Effects
This sensor is the convergence point of two Synaptics threads already in the coverage: the ClearForce pressure-sensitive screen technology announced in late 2015, and the optical under-glass fingerprint sensors debuted in December 2016 for next-generation phones. By folding force detection, swipe gestures, and software navigation-button support into a single reader slated for Q3 2017 mass production, Synaptics is positioning the fingerprint sensor as an input surface, not just an authentication module.
It also slots into the company's broader authentication push — weeks earlier it unveiled a multi-factor system combining fingerprint and facial recognition. The bet: whoever owns the sensor layer owns both security and interaction as phones shed physical buttons.
First-order effects
- Phone makers integrating the sensor gain a way to drop the physical home button without losing gesture or press input, since those functions move onto the fingerprint reader itself.
- Synaptics gets a differentiated pitch against commodity capacitive sensor vendors ahead of the Q3 2017 production window, bundling three functions into one component.
Second-order effects
- Component consolidation pressures rivals to match the feature set — Qualcomm ultimately answered in the same category with an in-screen ultrasonic sensor offering a larger input area, after mixed results in the Galaxy S10.
- OEMs designing around under-glass sensing shift bill-of-materials decisions toward display-stack integration, raising the bar for suppliers still selling standalone home-button readers.
Third-order effects
- If the pattern holds, the fingerprint sensor becomes a permanent fixture of the display itself rather than a discrete part — a trajectory the corpus confirms, with Synaptics later putting an in-display sensor into mass production with a top five OEM.
- Authentication hardware doubling as interaction hardware gives sensor vendors leverage over both UX design and security architecture, concentrating value in fewer, more capable biometric components.
The trend: Smartphone fingerprint sensors are evolving from single-purpose authentication readers into multifunction input surfaces embedded in the display stack.
