The D3200 with auto ISO set to a high of 3200, even with flash indoors, the ISO can go below 3200. It all depends on the level of ambient light.
I just took an indoor photo with and without flash. The room was not bright but not dark either. Without flash Auto ISO set ISO to 2500. With flash it set ISO to 2000 using aperture priority set to f5.6. If I set the lens to f1.8 the ISO went down to 400. In my darker den I took another flash photo where auto ISO set it to 3200 at f5.6. At f1.8 it dropped to ISO 1400.
Auto ISO can be a valuable tool for pros and amateurs alike. But I would advise everyone to learn how it works. For those that want to learn how their camera works I would advise to not use auto everything.
