LG enV2 (VX-9100)

I am on my second maroon enV2. Both have he same glitch. When I take a picture and try to save it, the phone powers down without warning, it shuts off and turns itself back on. Both did same exact thing and it is randomly, does not do it every time. Any advice?

I ordered the second one via tech support. Only had first one for 9 days..now have had this one for 4 days and same problem. ☹️
