The Android app was already updated a few days back with the voice recording and share feature. Apart from the voice recording you are also able to share video recordings right from within the app. The UI looks like what you see on the screen capture(from Facebook app itunes page) on the left. As you can see, the buttons are much visible on the screen and you can also decorate your messages with the emote-icons available on the footer part of the screen.
Some people have reported the voice recording has a strange way to be used. The record button needs to be pressed all the while you record the voice message. If that's true its a bit of a surprise and we are sure the users would rather prefer a more start and stop rather than the all the way pressing of the button. However, the current process is to hold the button and once you are done, just release. The release makes the message being sent to the contact as an automatic step in the process. In case you need to cancel the recording, just slide the finger off the recording button, that's it!
Facebook also has quietly updated the relevance of its Nearby tab in the app. As per the company the updates bring in more relevance so you are able to search what you actually are looking for. This also means the checkins gets a bit more accurate. Use the app and let us know how you find it.
