Samsung has released a new software update for the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra. This brings camera improvements and fixes to the Galaxy S23 trio.
For starters, the autofocus algorithm has been changed to take faster photos. In other words, when the user presses the camera shutter button in the default camera app, the phone’s camera takes a picture, even if it’s not fully focused.

However, if you want the app to capture the photo only after the proper focus is set, you can change the behavior by going to camera assistant > Prioritize focus over speed menu. Check the image below for more information about the update.
