 In order to use the Dominant Speakers call feature for Android, the first step is to obtain the Dominant Speakers feature API object:
 
 ```java
-DominantSpeakersFeature dominantSpeakersFeature = call.feature(Features.DominantSpeakers);
+DominantSpeakersFeature dominantSpeakersFeature = call.feature(Features.DOMINANT_SPEAKERS);
 ```
 The Dominant Speakers feature object have the following API structure:
 - `OnDominantSpeakersChanged`: Event for listening for changes in the dominant speakers list.
 - `getDominantSpeakersInfo()`: Gets the `DominantSpeakersInfo` object. This object has:
     - `getSpeakers()`: A list of participant identifiers representing the dominant speakers list.
-    - `getTimestamp()`: The date when the dominant speakers list was updated. 
+    - `getLastUpdatedAt()`: The date when the dominant speakers list was updated. 
 
 To subscribe to changes in the Dominant Speakers list:
 
 ```java
 
 // Obtain the extended feature object from the call object.
-DominantSpeakersFeature dominantSpeakersFeature = call.feature(Features.DominantSpeakers);
+DominantSpeakersFeature dominantSpeakersFeature = call.feature(Features.DOMINANT_SPEAKERS);
 // Subscribe to the OnDominantSpeakersChanged event.
 dominantSpeakersFeature.addOnDominantSpeakersChangedListener(handleDominantSpeakersChangedlistener);
 
 private void handleCallOnDominantSpeakersChanged(PropertyChangedEvent args) {
     // When the list changes, get the timestamp of the last change and the current list of Dominant Speakers
     DominantSpeakersInfo dominantSpeakersInfo = dominantSpeakersFeature.getDominantSpeakersInfo();
-    Date timestamp = dominantSpeakersInfo.getTimestamp();
+    Date timestamp = dominantSpeakersInfo.getLastUpdatedAt();
     List<CommunicationIdentifier> dominantSpeakers = dominantSpeakersInfo.getSpeakers();
 }
 ```
