 ### Fixes
 
+- Use React `componentStack` as fallback when error has no stack trace on Android ([#5965](https://github.com/getsentry/sentry-react-native/pull/5965)
 - Add `SENTRY_PROJECT_ROOT` env var to override project root in Xcode build phase scripts for monorepo setups ([#5961](https://github.com/getsentry/sentry-react-native/pull/5961))
