Twitter updates its Android and iOS apps, to make it easier to discover and follow conversations in your home timeline. People come to Twitter to take part in these real-time, global, public conversations. To date, such exchanges haven't always been easy to follow. With this in mind, Twitter have now made it easier for you to see conversations as they're taking place.
Tweets that are part of a conversation are now shown in chronological order so it's easier for you to follow along. You'll see up to three Tweets in sequence in your home timeline; if you want to see more, you can tap a Tweet to see all the replies, including those from people you don't follow. We will start rolling this out to everyone today. On Android and iOS, you can share individual Tweets over email, and on Android you can share via direct message (DM) as well.
User safety enhancement on Android:-
Additionally, you can now report individual Tweets for abuse or spam directly from Twitter for Android. This feature will be rolling out gradually; it's already available on Twitter for iOS.
Even more on Android:-
Twitter have improved the Twitter for Android experience on entry-level Android smartphones with limited storage, such as the HTC Explorer, Samsung Galaxy Y, Micromax Bolt, etc. For these devices, the Twitter app is now less than half the previous size, making it much faster to download and easier to install.
