+### [react-native-performance+5.1.4+001+fix-soft-crash-by-checking-for-active-react-instance.patch](react-native-performance+5.1.4+001+fix-soft-crash-by-checking-for-active-react-instance.patch)
+
+- Reason:
+
+    ```
+    `react-native-performance` emits some events using `RCTDeviceEventEmitter` on Android. Emitter should be used only after react instance has been created.
+    Otherwise, soft exception is thrown:
+      
+      ```
+      raiseSoftException(callWithExistingReactInstance(callFunctionOnModule("RCTDeviceEventEmitter", "emit"))): Execute: reactInstance is null. Dropping work.
+      ```
+    ```
