Android: One of the most helpful features of Google’s Android keyboard is keeping your own personal dictionary. Not only does this save words you use that aren’t necessarily in the regular dictionary, but it can be a handy shortcut. Now, your custom changes can sync across devices.
Stricly speaking, the option to sync your dictionary has been sort of available for a while, but it was only accessible through your Google Account Dashboard, which is a pretty silly place for it. Now, you can manage your sync options directly from the Google keyboard settings.
Finally, no more teaching a new device your nuances all over again. The update is rolling out now, or you can skip the line and get the updated version from APK Mirror here.
