since 9.05 I recognized frequent restarts of my H1i Plus. It happens while navigating, just recording an activity and even w/o activity by doing something in the settings. Because of the many bugs, I look frequently on the device and remarked restarts, but maybe it happens unrecognized too. When I recognized it, I stay and wait for the reload before I continue to hike. On the screen is a straight line in the recorded actity from where the device seems tp stop recording, but in the saved activity it seems like it has been recorded completely.
