3. You can resize the keyboard if you need to
Manufacturer-bundled keyboard apps are often challenging at best, and frustrating at worst. LG wants to change this, and it's given some special attention to the built-in keyboard. Usefully for a larger phone, the height of the keys can be adjusted down to wherever's most comfortable. There's also a word preview area just above the number row, letting you see what you're typing without glancing up. And like SwiftKey, it's capable of learning and adapting as you use it for more accurate auto-corrections.
And the new setup seems to work pretty well, but we're not sure it's ready to replace our favorite aftermarket keyboards just yet. (Plus we're using a combined English/Korean keyboard on our Korean G3, so there's that.)
