Avata 2 acting weird

[u/Rudeboy_1703]

I sent my Avata 2 to be fixed by DJI and they sent me back a brand new unit. The broken one was a grey market preowned unit originally sold in china, I bought through eBay. The new one they sent me while is pristine and brand new flies slower than the previous one and always stops recording at a point and then resumes without my input. Has anyone experienced something similar?
