Samsung Galaxy S3 owners on US Cellular will soon have good reason to jump for joy as the company’s version of the Galaxy S3 is getting a big new update. This update will add the multi-window features that folks on many other carriers have been enjoying for a bit now. Beyond that useful multi-tasking tool, the update will bring Smart Switch support, the latest version of Samsung’s gallery app, and more.
The upgrade is available for download over-the-air, so you’ll want to do well to make sure you’re on a WiFi connection before initiating the download. It also isn’t a horrible idea to get your battery charged up to 30% – 50%. Once you’ve taken care of that, you can head to the settings menu and choose the software update option to get started. You’ll be looking for version R530UVXAMD4.
