I took my drone out for a flight of about 5 minutes. Everything seemed normal. Then, about 2 hours later, went to fly it again and as soon as it got about 800 feet or so away, i got a critical voltage message and the drone went into landing mode. I couldn't over ride it at all and it came down in a tree breaking 2 props then fell to the ground breaking the camera off the gimbal. I had just done a firmware update on my android tablet prior to takeoff. Has anyone else experienced this? DJI GO app says 3.1.11 version 1.9.20
