1. Check the behavior and logs

• Check any suspicious error is showing up on log

2. Check the setting on Android

• Check any settings are missing on the file below
  • settings.gradle, build.gradle, app/build.gradle, MainApplication.java, MainActivity.java

3. Read documents

• Create RN project from scratch and check the diff between our project
• Check document of CodePush and React Native Navigation(which are the largest diff on the Native side)

4. Simplify/breakdown codebase to triage the bug

• Remove anything related to React Native Navigation
