Google's official Android keyboard has just been updated in the Play Store without a new changelog, and you know what that means. Yes, time to go hunting. Although, the keyboard makes you painfully aware of at least one new feature when you first try to type something.
What's New
That popup you see above is opened after the update when you tap the notice about personalization Google has helpfully tucked into the suggestion bar. It reads, "Personalization is on. Touch for info." The Google Keyboard now pulls from all the data Google has on your typing to improve suggestions. You can shut it off if you don't want it doing that, though. Here are the relevant strings in the APK.
<string name="prefs_key_popup_show_up_duration_settings">Key popup show up duration</string>
<string name="prefs_key_popup_dismiss_duration_settings">Key popup dismiss duration</string>
<string name="prefs_key_popup_show_up_start_scale_settings">Key popup show up start scale</string>
<string name="prefs_key_popup_dismiss_end_scale_settings">Key popup dismiss end scale</string>
<string name="use_personalized_dicts_summary">Learn from Google apps and services and your typed data to improve suggestions</string>
<string name="use_personalized_dicts">Personalized suggestions</string>
<string name="important_notice_title">Personalization is on. Touch for info.</string>
<string name="important_notice_contents">"The Google Keyboard uses data from Google apps and services to improve suggestions and corrections. The keyboard stores this data on your device.
To erase this data, or to turn off this feature, go to keyboard settings and uncheck Personalized Suggestions."</string>
<string name="prefs_dump_contacts_dict">Dump contacts dictionary</string>
<string name="prefs_dump_user_dict">Dump personal dictionary</string>
<string name="prefs_dump_user_history_dict">Dump user history dictionary</string>
<string name="prefs_dump_personalization_dict">Dump personalization dictionary</string>
The special debug menu (accessible with a little workaround) also includes an option to dump the personalized suggestions, as well as some options for key popup behavior. One more tiny change is found in the Advanced menu where you have a key popup dismiss delay (default or none).
