It seems that I have found the problem. According to https://facebook.github.io/react-native/docs/running-on-device, when you build and run the app on your device, your app will load js files from the packager on your computer, so you can live reload your app. That means your device has to be connected to your computer or has to be in the same wifi network as your computer. If your device can't access the packager, it will stuck on the splash screen and quit.

To run on your device reliably, edit build schema and build release version.
