I also received this update on my Indian variant of the Galaxy S25 Ultra around 2–3 days ago. I installed it and it’s been more than a day since the installation was completed. So far, I haven’t found any issues. In fact, I’ve noticed a little improvement in battery optimization and performance after this update.

So yes, you can safely download and install the update on your device. Just make sure your phone is not warm during installation. If it feels hot, let it cool down first, then start the update. Once the download and installation are complete, give your phone a few minutes to finish background optimization before using it normally. 👍
