Default [Q] Slow Mo not working

While playing with my phone (which I love by the way), I tried out the slow motion option in the video settings with 1/8 slowness selected. I was able to record, but when stopping the recording, the progress bar goes about a quarter of the way and freezes. After about 5 minutes, the camera app stops working, the file is corrupt and I have to reboot the phone to get the camera to work again. I even tried to record something for all of five seconds just to see if the file size/conversion had anything to do with it, but still got the same results. Anyone else have this issue? It's not a life-changing problem, but still want it to work regardless.
