Hello Sir, if "camera sensor error" does not disappear after you upgrade it and restart aircraft for several time, it needs to be sent in to service center for further analysis and fixing.
Because the props attached the cupborad and had minor marks on, it would be best to get it checked with our tech support. Please sync your flight records on your APP as the tutorial, then send e-mail to support@dji.com with your APP account and time when it happened for further help.
"I felt like an idiot." As you should. First off, you posted a URL that has nothing to do with this forum and your post should be removed, and second, An idiot shouldn't be in possession of a drone and try to fly it in the living room!
To DJI Natalia. uR43GeZNQhm4 has made several posts on this forum advertising http://www.gzvirginhair.com/ which has nothing to do this this forum! Yet you keep responding to his ploys! This is clearly a scam that shouldn't be allowed on this forum.
