Samsung Throttlegate patch rolling out to the S21s
While the S22 was the most talked about phone affected by the Game Optimization Service issue of the last couple of slow news weeks, every Samsung device probably was affected that had it on it. One UI 4.1 adds the ability to turn off the service, as well as allowing things such as using the telephoto lens on Pro camera mode (something that was inaccessible before.)
Gallery has been updated allowing for post-photo remastering of lighting and adding portrait effects. Time lapse photos are also listed as supported.
Widget grouping is listed as a thing to save space on your home screen, not a lot described in it. Better integration with Google Duo is also listed.
