Samsung to use Touch ID-like fingerprint sensor in Galaxy S6 instead of swipe-based sensor
Exclusive: Samsung opts for a touch-based fingerprint sensor for the Galaxy S6 — A smartphone is one of the most personal devices a human being can own, and it's one of those devices where compromising on security is not an option.
Context & Ripple Effects
Samsung's swipe-based fingerprint reader on the Galaxy S5 was the weak link in an otherwise flagship feature set — slow, error-prone, and awkward for the one-handed use mobile payments demand. With the Galaxy S5's fingerprint data later shown clonable by researchers, the stakes around getting this hardware right were only rising.
The Galaxy S6's shift to a press-and-hold, Touch ID-style sensor brings Samsung onto the interaction model Apple validated, and it sets up everything that follows in the corpus: the Galaxy S8 layering facial and iris scans on top for Samsung Pay authorization, and Qualcomm eventually pushing the reader under the glass entirely with an in-screen ultrasonic sensor after mixed results in the Galaxy S10.
First-order effects
- Galaxy S6 buyers get materially faster, more reliable unlocking and a sensor actually suited to authorizing mobile payments, closing the usability gap with Apple's Touch ID.
Second-order effects
- Sensor suppliers race to differentiate on the new touch-based baseline — Synaptics' next-generation reader adds force detection, swipe gestures, and support for software navigation buttons, turning the fingerprint module into a design input rather than just a security part.
Third-order effects
- Once the touch sensor becomes the phone's trust anchor for payments, OEMs stack additional modalities on top of it — Samsung's own Galaxy S8 added facial recognition that could be fooled by a photo, pushing vendors toward multi-factor biometrics and, eventually, in-screen sensors like Qualcomm's ultrasonic design.
The trend: The fingerprint reader is evolving from a convenience unlock into the phone's core trust boundary for payments, driving a supplier arms race across touch, multimodal, and in-screen sensing.
