A few weeks back I had a hard landing. I picked out blades of grass and some other debris from the air intake. Everything seems to work fine but every once in a while I hear a funny noise when the fan is on, almost like grinding. I can give it a little shake and it will quit. I really think something may have been ingested and I wasn't able to get it out. It isn't something I really want to send it back to DJI to check out as I think it is very minor, but I have been thinking about opening the case to see if I can pick out whatever it is. I have only had my Mavic since April so it is still under warranty so I am very hesitant to open it up. Does DJI have tamper seals around the case?
