The OnePlus 15T has finally caught up to Samsung’s ultrasonic biometrics

OnePlus is launching the OnePlus 15T in China on Tuesday: a 6.32-inch OLED, 165 Hz display handset powered by Qualcomm's Snapdragon 8 Elite Gen 5 and using Qualcomm's 3D ultrasonic in‑display fingerprint sensor. The device brings OnePlus to parity with Samsung's ultrasonic biometrics (Qualcomm 3D Sonic family, with Suprema algorithms on Samsung devices), while Samsung's Galaxy S26 adds an 'Improve accuracy' rescan feature (rescans finger 10 times) in One UI 8.5 to boost unlock reliability. Suppliers and biometric-algorithm providers (Qualcomm, Suprema, Goodix) remain key beneficiaries as ultrasonic sensors become standard across flagships.

Analysis

Qualcomm stands to capture a disproportionate share of the margin upside from a marketwide tilt to ultrasonic in‑display sensors because the vendor with the dominant system‑level IP and sensor ASIC can cross‑sell authentication, DSP, and modem subsystems into the same design win. Scale here matters: an incremental 5–10m units a year that standardize on Qualcomm’s 3D Sonic family would flow through as high‑margin software/firmware licensing and higher ASPs on platform bundles rather than commodity sensor hardware, concentrating profit capture into QCOM’s financials over 3–12 months.

A seemingly small UI change—Samsung’s “Improve accuracy”—is a productization lever that lengthens perceived device life and reduces service friction, which decreases churn and increases feature stickiness for the underlying sensor stack. That has second‑order effects for aftermarket and warranty costs for OEMs, and it raises the bar for rival sensors whose advantage is “good enough” hardware but weaker software refinement; winners will be those who pair ultrasonic transducers with robust matching algorithms and lifecycle update paths.

Key risks: Chinese OEMs opting for domestic sensor suppliers or rapid advances in optical algorithms could blunt Qualcomm’s share gains within 6–18 months, and regulatory/licensing pressure in China remains a material tail risk that could force OEMs to sidestep Qualcomm IP. Also, sensor revenue is still a small fraction of QCOM’s total — even large share gains produce modest absolute EPS upside unless accompanied by broader SoC/5G design wins.

Tactically, expect measurable signals within the next 1–4 quarters: announcement cadence of additional design wins, OEM statements on biometric roadmaps, and any pricing/royalty disclosures in Qualcomm’s quarterly 10‑Q/K commentary. Those are near‑term catalysts that will re‑rate the magnitude of capture into QCOM’s margins.

Key Decisions for Investors

• Long QCOM (equity) or buy 6–12 month call spread on QCOM to express asymmetric upside to platform consolidation; target +20–30% upside if additional Android flagships standardize on Qualcomm 3D Sonic integration. Max loss = premium paid; position size 1–2% of portfolio.
• Pair trade: Long QCOM / Short Goodix (603160.SS) over 6–12 months to play platform consolidation vs cheaper sensor incumbents — size the short notional to equate market‑cap sensitivity and target 2:1 reward:risk if QCOM captures share. Close on signals: Goodix loss of top OEM designs or Qualcomm public design‑win releases.
• Protective hedge: Buy a 2–3 month QCOM put (or put spread) sized to cover 20–30% of the long exposure ahead of the next Qualcomm quarterly print or a major phone launch window; this caps downside from a cycle softness or negative licensing surprise.
• Tactical underweight: Reduce exposure to smaller biometric/sensor suppliers and non‑integrated SoC vendors until they demonstrate comparable software pipelines and update/service economics; re‑visit after 2 quarters of revealed design wins or algorithm partnerships.
