Crashes with the following exception:

terminating with uncaught exception of type facebook::jni::JniException: java.lang.ClassNotFoundException: Didn't find class "com.facebook.hermes.unicode.AndroidUnicodeUtils"

This only happens in release build on real devices.

Are you using proguard? For me adding the following line to proguard-rules.pro resolved the problem:

-keep class com.facebook.hermes.** { *; }
