How to get some fantastic Android L-inspired keyboard themes on the LG G3
Fed up with the LG G3's limited choice of keyboard colors, which is distilled to the eternal dilemma of White and Black? Here's a magical solution that doesn't involve rooting, installing third-party keyboards, or anything else short of downloading and installing some .apk files.
Developer Ashrockr from the XDA Developers Board has put together a selection of Android L-inspired themes in bright colors that make for a more vibrant typing experience. If you enjoy using the stock LG Keyboard, these themes will be the icing on the cake.
Here's how to get them aboard your LG G3:
First things first, you must enable app installation from unknown sources. If you have done that, skip this step and go to the next one. If you haven't, go to the "Settings", "General", "Security" menu and tap "Unknown sources, then hit 'Enable'.
Second, open this link on your G3 in your mobile browser of choice. It leads to a thread in the XDA Developers board. Scroll down to the attached files in the first and second post, and download them on your LG G3. After you're finished, open the phone's app drawer and look for the 'Downloads' app. Therein lie your newly downloaded keyboard theme .apk files. Tap on each one of them and hit 'Install'.
Installed everything? The next, and final step is to head to the "Settings", "General", "Language & input" menu, and tap the big ol' gear icon next to 'LG Keyboard'. In the next menu, tap "Keyboard height and layout", then hit 'Keyboard theme'.
