I meant about ONE UI 3.0. if you already got it then clear the cache of camera application. It might help. And about January update. I don't think so cause recently we received update from December and Also android update. Let's see what happens.
Please be assured and to resolve "Camera" issue please follow below given steps:
1. Reset the camera settings:- Tap on Camera > Settings > Reset settings > Tap on Reset.
2. Check device in safe mode:- Using Safe Mode on a Samsung phone allows you to force the device to run the essential operating system, and disable most 3rd party applications. To enter in safe mode: Press and hold the Power key, when Power off icon appears>Press and hold the power off icon. To Exit safe mode: Restart the device.
If the issue still persist, kindly register your concern in Samsung Members app (Samsung Members app > Get help > Feedback > Error report/ask question). Note: Please send device log files within 15 minutes of issue occurrence along with the exact issue details.
