Sorry for my late response but I've been rather busy lately.
I kept on looking at the two sets of pictures and I must say there are some interesting things happening there. I assumed that the objects in focus are the boxes of Crunchies and the chair on the grass, respectively. I took a look at the EXIF data and it might explain a lot.
Indoor picture:
Auto: The blur seems to be caused by movement. If the exposure time is correct (1 s) than it is very much explainable. I'm not sure how capable Samsung's OIS is, but from my experience 4 stops is what OIS would compensate for and there are approx 5 stops (1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1) between pro and auto exposure times.
Pro: The exposure time is just about right for a clear shot (1/50 sec). The exposure seems to be calculated differently, for whatever reason.
Outdoor picture:
Auto: Same as before, there is a 1 sec exposure time.
Pro: The photo seems to be more sharpened in pro mode.
I would recommend you wipe the cache of the camera app and try again. If the results are not improving then try wiping the data of the camera app. If things are still blurry, call Samsung service center. There is a possibility that your camera module is not properly calibrated.
