When an app fails in the field

A crash that only appears on a customer phone is hard to reproduce at a developer desk. We collect the stack trace, the device model and the exact steps that trigger the fault before touching any code.

Tracing the root cause

Logs from the laptop build and the mobile client are replayed side by side, so network timeouts, memory pressure and permission errors are separated from genuine logic bugs. Every candidate cause is reproduced at least twice before it is reported.

Fix and verification

You receive a patch proposal with the affected files, a short explanation of the cause and a test checklist that covers the failing path plus the two adjacent flows most likely to regress.
