If you've used Android 4.1 or later on a phone or tablet with 1GB of RAM, you know things can get a little tight in the memory department. That's what makes newer and slightly underpowered devices like the Lenovo Yoga a little disappointing. Google has decided to trim the fat with Android 4.4 in an initiative they've christened "Project Svelte." This isn't a single change, it's a wide range of additions to the Android API and optional hardware configurations designed to make KitKat run smoothly on devices with as little as 512MB of system memory.
According to the new 4.4 developer page, Project Svelte starts with recommendations and options targeted at device manufacturers.
