+# Expo Haptics Patch
+
+Whenever we migrated to Expo Haptics, there was a difference between how the previous and new libraries handled the
+Android implementation of an iOS "light" haptic. The previous library used the `Vibration` API solely, which does not
+have any configuration for intensity of vibration. The `Vibration` API has also been deprecated since SDK 26. See:
+https://github.com/mkuczera/react-native-haptic-feedback/blob/master/android/src/main/java/com/mkuczera/vibrateFactory/VibrateWithDuration.java
+
+Expo Haptics is using `VibrationManager` API on SDK >= 31. See: https://github.com/expo/expo/blob/main/packages/expo-haptics/android/src/main/java/expo/modules/haptics/HapticsModule.kt#L19
+The timing and intensity of their haptic configurations though differs greatly from the original implementation. This
+patch uses the new `VibrationManager` API to create the same vibration that would have been seen in the deprecated
+`Vibration` API.
