I’m glad Google didn’t decide to revamp android again like they did with Ice Cream Sandwich. It’s about time they start working on optimization rather than introducing something completely new that can be sloppy. A good example of how much they’ve improved the response time on Android can be seen here showing what’s it like in slow motion.
Notifications are one of my favourite features on Android and it just got even better. You can now see much more details from notifications directly. They’re now expandable, meaning you can click on one and expand to see more emails or more photos while still being inside the notification.
I have mixed thoughts about the new keyboard. Getting word predictions is great but I already use SwitfKey which does exactly that and is the best at what it does. I’m not sure Google copying the exact idea from a popular keyboard is the best way to go. But they also worked improving Arabic and voice-to-text recognition which is great.
