Mobile networks can sometimes be inconsistent or spotty, which means that even if you have a connection when you start your search, it might fail before you get your results back. With this change, search results are saved as soon as they are retrieved, even if you lose connection afterwards or go into airplane mode. So the next time you lose service, feel free to queue up your searches, put your phone away and carry on with your day. The Google app will work behind-the-scenes to detect when a connection is available again and deliver your search results once completed.
