Google Keyboard is one of many different options available in the Play Store for users to download and augment their typing experience for anything from texts to emails. Whatever it is you're typing on your smartphone or tablet, having the right digital keyboard for the job can make a world of difference. The right keyboard can be one that offers a more functional utility like the auto correction system that many employ, or for some it can be a keyboard that offers a wide selection of themes and keyboard customization options. If you lean more towards the side of having a larger selection of customization elements, Google Keyboard may now be worth checking out as v5.1 is starting to hit the Play Store.
For those who are unfamiliar, Google introduced a version of Google Keyboard with the Android N developer preview which introduced keyboard themes that could be applied. This was basically limited to simply having more color options in addition to light and dark, but also the ability to take a user-designated image and apply it as the keyboard backdrop. That version of the Google Keyboard now seems to be hitting the Play Store for anyone who wants to install it. It is worth noting that, while this version does also include the new unicode 9 emoji, you'll need to be running Android N to use them, so this particular part of the app version will be limited to anyone who has the Android N Developer Preview installed on their device.
For anyone else, you'll find an improved set of colored keyboard themes at your disposal after installing or updating the app including green, pink, and blue. Since this is just beginning to roll out to the Play Store, it's entirely possible and quite likely that it could take a few days to reach everyone. Having said that, you can grab the APK below if you want to install it now. Other than the new theme colors and the unicode 9 emoji, it doesn't seem like there is much else to see, although the update probably includes general bug fixes and improvements as app updates usually do.
