Our Bug Fixing Process

8 steps to fix your app

Every step is performed live on a recorded screen-share so you see exactly what was done.

Bug Report Review

Review your bug description, crash logs, screenshots, steps to reproduce and expected behaviour.

Environment Setup

Clone your repo, install dependencies, configure environment and reproduce the bug locally.

Root Cause Analysis

Debug with breakpoints, Crashlytics logs, network inspector and profiler to find the exact cause.

Fix Implementation

Write the fix with clean code, handle edge cases and ensure no regressions in related features.

Testing & Verification

Test the fix on multiple devices, screen sizes and OS versions. Verify the original bug is resolved.

Performance Check

Run profiler to confirm no memory leaks, CPU spikes or battery drain introduced by the fix.

Build & Deploy

Create release build, test on real devices, prepare for Play Store/App Store if needed.

Report & Handover

Bug fix report with root cause, what was changed, testing proof, documentation and full handover.
