Instead you can simply say "OK Google" to your smartphone and you'll be able to do voice search send a text message get directions or even start playing music. Speaking of voices the phone app has gotten a revamped look. Instead of the tired alphabetical sorting KitKat will evaluate which contacts you speak with most often and automatically prioritize your contacts list accordingly. Also the phone app is integrated with Google Maps, so you'll be able to look up nearby restaurants and hotels directly from the app. On a related note Caller ID also gets some Google Maps integration as well. If you receive a call from a phone number that is not in your contacts Google Maps will search and display any matches from local businesses. It's clear that Google's goal with Android 4.4.2 Kit - Kat is reduced Android fragmentation and a personal customized experience.
