Problem we solve

My app works everywhere except on one phone brand

One manufacturer, one firmware quirk — and your reviews tank.

How we reproduce, isolate and patch crashes that only happen on a specific device family without breaking everything else.

Signs this is your problem

You will recognise yourself in at least one of these

  • Crash reports cluster around one manufacturer or model line.
  • Same build runs flawlessly on Pixel and iOS but freezes or skips features on the affected device.
  • Negative reviews mention the brand by name and word spreads in the user community.
  • Crashlytics shows the trace but the stack does not lead anywhere obvious.

Why it happens

The root cause, in plain language

Vendors customise their Android forks heavily — camera, permissions, background limits, fonts, even threading behaviour. A non-standard quirk in firmware silently breaks an assumption your code makes.

Our approach

How we actually fix this

  1. 1

    Reproduce the crash on physical hardware from the affected brand — emulators do not catch this.

  2. 2

    Bisect against recent releases and isolate the exact API, intent or permission that misbehaves.

  3. 3

    Implement a targeted workaround instead of a global rewrite, with feature flags to keep it scoped.

  4. 4

    Add that device family to our compatibility test matrix so the regression is caught before release, not after.

What you can expect

Outcomes our clients see

  • Targeted patches shipped within days, not weeks.
  • Per-device crash rate measurable and tracked over time.
  • Confidence to ship without fearing the next vendor-specific firmware update.

Case study

Single-manufacturer crash wave

A wave of complaints came in from users on one phone brand. The app would crash on launch or skip key features. We reproduced the issue on physical hardware, traced it to non-standard firmware behaviour, and shipped a targeted fix within days.
