R10 - Driving Range Screen Black & No Video

Just purchased the R10 - all software is updated (latest Garmin golf app and R10 updated)

The R10 seems to work fine for quite a while (we are using the driving range mode and have it setup to record swing videos) and then we encounter the following problem.

Not sure exactly what we do, probably switching screens to look at different stats or watch a video... BUT...

 1. The driving range screen goes black.. we do not see the graphic for the range.
 2- Even though video recording is enabled, it shows a video is recorded but when we try to play it back.. it just shows a black screen
 3. The R10 stops showing all the stats.. we get some stats but not all

After this happens, we try closing / restarting the app, ending the range session and starting a new one, restarting the R10 and even restarting the phone...

BUT - event after reset.. the range screen still comes up black and new videos still show a black screen

The next day when we set it up, everything seems to start working again....

Any help or more information would be appreciated...
