The Galaxy S10 and its siblings aren't even completely in the public's hands but Samsung is already rolling out its first update to the device. That is probably for the best because it's an update that many won't want to skip. At least those who have considered the Bixby button the bane of their life. With the latest update, they can now remap that to what they want. Even better, the update may have a thing or two bonuses as well.
