Bisect changes
When reproduction is rare, bisect commits or toggles to isolate the first bad revision.

Reproduce mobile app bugs
You cannot fix what you cannot see. Start from user context—app version, OS, device class, locale, network—then narrow to a minimal path. Use debugging tools, match device profiles, and align with Android-specific reproduction notes already on the site.
Capture first
- Exact build number, feature flags, and time window of the report.
- Crash or ANR stack traces with symbols where possible.
- Screen recording or ordered steps from support—not only free-text summaries.
Narrow systematically
Match reality
Replicate OS band, low-memory state, and offline/online transitions tied to the ticket.
Add a guard
Turn the repro into an automated or scripted check so the bug cannot return silently.
How Device Changer fits
Hand the same simulated context from support to engineering, then keep it for regression after the fix ships.

FAQ
Bug only happens in production—now what?
Compare config and data: remote flags, CDN assets, TLS pins, and account cohorts differ from staging.
Intermittent bugs?
Log with correlation IDs, add lightweight counters, and reproduce under stress (CPU, network delay) once a hypothesis exists.
