React Native app is not running on physical device

Issue

I am running a react native app but this app is running fine on emulator but not running on physical device. App is installed successfully and opened on physical device, but on opening it shows white screen for a while after that it is crashed/closed. Unable to find reason.

When I am running project through android studio on physical device, it is giving me this error:

E/SoLoader: couldn't find DSO to load: libflipper.so caused by: dlopen failed: cannot locate symbol "_Unwind_Backtrace" referenced by "/data/app/com.project-xyz==/lib/arm64/libflipper.so"... result: 0

StackTrace is:

    D/SoLoader: About to load: libflipper.so
    libflipper.so not found on /data/data/com.project/lib-main
    libflipper.so found on /data/app/com.project-xyz==/lib/arm64

Solution

One thing is to Update FLIPPER_VERSION. Second is to make sure that your device is connected to your system, react native (in debug mode) creates a localhost on the system and runs the app on device (device connected to system through a wire). If you will disconnect the device, it will not work properly.
