Galaxy S23 series phones are already being sent out to some customers who pre-ordered, but for most folks around the world, the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra are still in the pre-order phase, with a release date of February 17.
There are plenty of ways you can pre-order a Galaxy S23, S23+, or S23 Ultra, but there's a good reason to do it on Samsung's official website: you get to choose from additional color options. More specifically, you get to choose a flashier color and colors with a lighter shade.
Samsung's website has additional colors for pre-order customers
For example, you can pre-order the Galaxy S23 Ultra in red from Samsung's wesbite. The red version is alo somewhat bland compared to previously released Galaxy flagships, but it's certainly flashier than the general four Galaxy S23 Ultra color options, all of which are muted and might not please everyone.
Just to be clear, the exclusive colors are only available for pre-orders. Samsung will remove them once the Galaxy S23 series goes on general sale. It might launch these phones in new colors a few months down the line, but that is not confirmed at the moment.
So, hurry up and place your pre-order on Samsung.com before the release date (February 17 in most countries) if you want a higher number of color choices. Those custom color choices are available in a lot more markets this time around (such as India), so be sure to check out the official Samsung website to see if that's the case in your country.
