Fixed-Scope Engineering Engagement

The Device Truth Audit

The problem

Across modern mobile engineering organizations, including our own 50+ repository fleet, a third to half of verification time goes to suite maintenance: re-running flakes, chasing device-only regressions, and arguing with red CI.

AI coding tools accelerate the gap. Code merges faster than engineering teams can verify it on physical silicon.

LINC Innovations trusts no build until it passes on physical hardware. That discipline is the foundation of this engagement.

Two ways in

Your suite is red, or nobody trusts it.

Week 1: triage. Your failure history (CI logs, test reports) clustered by failure signature, separating true regressions, environment flakes, device-specific failures, and test-authoring debt. The method is built on the machine-learning failure-triage architecture our founder built at Amazon Prime Video: 500K+ test results a month, 98% clustering accuracy.

Week 2: root cause on real devices. Top offenders reproduced and root-caused on physical hardware with runtime debugging (breakpoint-level, not log-guessing) and full evidence capture: screen video, device logs, UI-tree diffs.

Your CI is green, and hardware bugs still reach users.

Pairing that drops. A reconnect that never comes back. A watch that stops syncing after the OS terminates your app overnight. A battery manager on one phone OEM that behaves like no other. None of it shows up in CI, because CI never pairs physical radios.

You ship us one unit of your hardware. Our bench runs your pairing, reconnect, background, and firmware-update flows in deterministic loops across real phones and watches, with the same evidence capture and the same runtime debugger. Same two weeks, same dossier.

What you get

Deliverable. A ranked engineering fix dossier: each top failure with root cause, debugger and video evidence, effort estimate, and a prioritized order that maximizes stability per engineering hour. Plus a failure taxonomy your team keeps running after the engagement concludes. We diagnose and rank. Your team implements.

A receipt on an external production app

In July 2026 we ran this methodology against the public CI of Nextcloud’s Android app. Inside the “flaky” noise sat a crash that terminated the app process. We filed it as #17337. The maintainers shipped the fix in #17373. This receipt ran in an emulator, not on the physical bench. It demonstrates the triage and reproduction method.

We then re-ran our reproduction loop on both builds in an Android emulator against their test server. Before the fix, 6 of 60 runs crashed. After it, 0 of 60. The fix shipped in Nextcloud 34.1.1.

Engagement Scope & Pricing

Standard Fixed-Scope Audit, from $7,500: one app, up to two platforms (e.g. iOS + Android from one codebase), 14-day turnaround. Additional platforms or hardware peripherals are scoped in the statement of work (SOW).

Scoped Single-Flow Baseline ($2,500). Up to 3 engineering teams per quarter can book a single-flow baseline diagnostic at $2,500 instead of $7,500 in exchange for an approved case study and one reference call. 3 of 3 slots open.

The diagnostic stands alone. No license, no commitment beyond the two weeks. If our bench finds nothing worth fixing, the report states so plainly.

After the two weeks, teams that want continuous physical verification can retain a managed bench at $4,000 a month, month to month: nightly runs on your devices or ours, failure triage, and a weekly engineering report.

Need one paired Wear OS + phone run instead of a full two-week diagnostic? Book a single watch + phone run ($49, 72 hours).

This engagement is not for pre-launch prototypes. With nothing in production, there is no failure history to cluster. It is built for teams that already ship and need hardware-level root causes before the next release.

Every claim in our methodology is verifiable before you book: inspect the sample executive report and the Nextcloud diagnostic receipt.

Non-disclosure agreement (NDA) on request. Your CI history and builds are analyzed in an isolated environment for the two-week engagement. Every artifact is delivered to your team and deleted from our systems after handoff.

One fixed-price SOW.

What you’d do instead

There are real alternatives. Here is where each one fits.

Two engineers and a Thursday with the device drawer. The usual default. It feels free because it is payroll. It rarely leaves an evidence trail, and it is hard to run the same way twice.

Appium or Maestro, plus that drawer. This works if someone on your team wants to own the rig. Our bench is that rig, already built and run every night on our own systems.

A cloud device farm (BrowserStack, Sauce Labs, AWS Device Farm, Firebase Test Lab). The right tool for coverage across OS versions and screen sizes. The devices sit in the vendor’s facility and you reach them remotely. Some offer SIM, biometrics, or Bluetooth on dedicated devices. But BrowserStack’s own FAQ says a Bluetooth device you hold cannot connect to their remote phones. And nobody wears a racked phone or unplugs it mid-run.

Crowd testing (Applause, Testlio). Real testers on real devices in real-world conditions, with results in your bug tracker. It is not a controlled loop, and the root cause stays with your team.

A robot lab (Mobot). Robots physically tap and swipe real devices, and Mobot advertises Apple Watch sync and Bluetooth tests, with screenshots and video of each run. It prices by test action. Mobot’s pricing post (January 16, 2025) says: “Test cases that require advanced features (biometrics, bluetooth connections, third party devices, etc.) have a 2x multiplier effect on test actions.” It fits scripted flows on their devices, running your test plan. Here it is your hardware on our bench, a runtime debugger attached, and a ranked root-cause dossier.

The bench

The audit runs on the same physical Hardware-in-the-Loop stack that builds, verifies, and ships our own four-platform systems (Android, iOS, Wear OS, watchOS). Deterministic verification agents drive physical phones, watches, and tablets (install, instrument, record, debug), with a runtime debugger attached when it matters.

It exists because we run it nightly on our own production apps, not as a slide-deck concept.

Engineering pedigree: over 10 years of mobile systems, edge sensor processing, and hardware-in-the-loop verification at Amazon (Prime Video), Paramount, and Ticketmaster. Physical device fleets, verification harnesses, release platforms, and ML failure triage. AWS triple-certified, PMP.
