I have had 3 Tellos to date - 1 returned with defective video, 1 current, and 1 purchased for a relation. All flew fine, but 2 out of 3 would only record video in B & White with occasional purple & green additions. This happened with two different Samsung Note 3 or 4 phones, so it doesn't appear to be the phone. Is it a camera or a software problem - any ideas please ?
