Support - Mobile App Bug Fixing Services
Crash fixes, build error resolution, store rejection support and stability improvements for React Native, Expo, iOS and Android apps.
I diagnose and fix mobile app bugs that block releases, hurt user experience or make your app unstable in production. Using React Native, Expo, Xcode, Android Studio, Sentry, Logcat and crash reports, I investigate crashes, white screens, build failures, dependency conflicts, App Store rejections, Google Play issues, performance problems and native module errors. Every fix is focused on the root cause, tested across iOS and Android, and prepared for a stable release.

What you need to know
Key details about mobile app bug fixing services — what it involves, how it works and what to expect.
Mobile App Bug Fixing Services
Mobile app bugs can block releases, break user flows or make an app unstable in production. I diagnose crashes, build failures, white screens, dependency conflicts and store submission issues using logs, stack traces and device testing.
React Native and Expo Bug Fixing
React Native and Expo apps can fail because of native modules, SDK mismatches, Reanimated issues, navigation errors, build configuration or dependency conflicts. I trace these problems across JavaScript, native settings and build tools.
iOS and Android Build Error Fixes
Failed builds often come from CocoaPods, Xcode signing, provisioning profiles, Gradle, Kotlin, manifests or incompatible dependencies. I fix build blockers and prepare stable builds for testing or release.
App Store, Google Play and Release Stability
Store releases need more than a successful build. I help review rejection causes, fix compliance or technical issues, test the release build and support resubmission to App Store Connect or Google Play Console.
What's included
Every mobile app bug fixing services engagement includes these core capabilities — tailored to your specific requirements.
React Native and Expo crash diagnosis using logs and stack traces
White screen, startup crash and runtime error fixes

How it works
A structured, transparent process from initial requirements to production deployment.
Reproduce
I reproduce the issue on real devices, simulators or emulators and collect crash logs, stack traces, build output and environment details.
Diagnose
I trace the issue to its root cause, such as native configuration, dependencies, runtime code, API failures, build settings or store compliance problems.
Prioritize
I rank issues by release impact, user impact and technical risk so the most important bugs are handled first.
Fix
I apply targeted fixes for crashes, build errors, dependency conflicts, performance issues, native modules or app store blockers.
Test
I test the fix across iOS and Android, key screens, affected flows, build variants and device sizes to reduce regression risk.
Release Support
I help prepare a stable build, verify production behavior and support App Store or Google Play resubmission where needed.
