Xiaomi is launching a new phone this new year. A teaser was recently posted on Mi's G+ account showing us an idea of a sweet surprise. The phone manufacturer will be making an official announcement on Sunday, January 4, of what could be a new Redmi. We're not sure if it will be a new Redmi model or just an improvement of the Xiaomi Redmi 1S. Based on the image and the post, my guess is it could be new colors or perhaps a Lollipop update based on the "sweet surprise" reference. But of course, all Android platforms are named after desserts so every version is supposed to be sweet.
