Having an app like Google Translate on your phone can be indispensable when you're traveling, and the latest update to Google's multilingual app adds a few improvements that should make it easier to use. The latest version 2.4.2 includes quick navigation between conversation, history and favorites modes on tablets (phones have had this feature for a while), in addition to easier copying of translations (there's now a button for that).
Other additions include text-to-speech options for your original text, and handwriting recognition options for more languages, though no word on which languages specifically.
If you've already got Google Translate installed, be sure to head by the Play Store to grab the latest update. Alternatively, you can install via the web interface.
