The approach follows a shift-left strategy across three phases: pre-merge/pre-production, release control, and post-release response. Prevention relies on Android Lint, SwiftLint, automated and manual testing, and Grab Early Access (GEA), a pre-production gate monitoring internal builds for crashes. During release, staged rollouts and feature flags limit exposure and let teams disable a crashing feature without a new release. Post-release, Grab uses Firebase Crashlytics and BigQuery for real-time crash monitoring plus automated triage mapping crashes to specific PRs. ## Full article daily.dev links to this article rather than hosting it.

Grab uses a layered defense across three phases: pre-merge/pre-production, release control, and post-release response. Prevention tools include Android Lint, SwiftLint, automated and manual testing, and Grab Early Access (GEA), a pre-production gate that distributes early builds to internal users and monitors them for crashes before wider release. _Teams scaling AI-assisted development can compare crash-prevention approaches like this one on daily.dev._ ### What is Grab Early Access (GEA) and why does it matter for crash prevention? Grab Early Access is a pre-production gate where early app builds are distributed to internal users and actively monitored for crashes. A crash seen by only a handful of internal GEA users would translate into a substantial crash rate spike, extra support load, and a potential hotfix at production scale, making GEA one of Grab's most important stability gates. _Engineers designing pre-release testing gates can find similar case studies on daily.dev._ ### How do feature flags help control crash rates during a mobile app release? Feature flags let teams activate features gradually while monitoring their impact on crash rates, independent of app releases. If a feature causes crash rates to exceed predefined thresholds, it can be disabled immediately without shipping a new release, limiting how many users are exposed to a faulty feature. _daily.dev helps engineers tracking release-safety practices like staged rollouts and feature flags stay informed._ ## Similar posts on daily.dev - [App stability at scale with a layered defense](https://daily.dev/posts/app-stability-at-scale-with-a-layered-defense-oj5muonda) · Grab Tech Blog · 0 upvotes · 0 comments - [Grab Reduces ANRs by 32% and improves startup time by 35% with R8 and Profile guided optimization](https://daily.dev/posts/grab-reduces-anrs-by-32-and-improves-startup-time-by-35-with-r8-and-profile-guided-optimization-houimzmmk) · Android Developers Blog · 0 upvotes · 0 comments - [Making sense of too much code](https://daily.dev/posts/making-sense-of-too-much-code-dl38jlw0t) · InfoWorld · 0 upvotes · 0 comments --- Tags: [#mobile](https://daily.dev/tags/mobile) [View this post on daily.dev](https://daily.dev/posts/how-grab-improved-mobile-app-stability-by-safely-handling-surge-in-ai-generated-code-changes-6wxfgfkus) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"How Grab Improved Mobile App Stability by Safely Handling Surge in AI-Generated Code Changes","url":"https://daily.dev/posts/how-grab-improved-mobile-app-stability-by-safely-handling-surge-in-ai-generated-code-changes-6wxfgfkus","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/how-grab-improved-mobile-app-stability-by-safely-handling-surge-in-ai-generated-code-changes-6wxfgfkus"},"datePublished":"2026-11-07T11:07:05.971Z","dateModified":"2026-11-07T11:08:05.527Z","description":"Grab built a layered defense strategy to keep mobile app crashes under control as AI coding assistants increase the volume of code changes per release.
