Review on 1ft Micro USB to Micro USB DJI Spark OTG Cable, Right Angle Data Cable for DJI Mavic Pro 2, Mavic 2 Zoom, Mavic Air, Mavic Pro Platinum, and DJI Spark - Compatible Phone to Controller, Pack of 1 by Nick Kirschenmann

Edited to add: After successfully using an iPad (Lightning connector) and a Note 9 phone (USB C), I decided to try the cable again the next day and it worked. I spent a lot of time trying to get it working the day before. I don't know what the difference is from one day to another but it works. Original: This cable did not work with my Samsung Galaxy Tab S2 8 and my DJI Mavic Mini drone controller. The short cable that came with the drone worked with the tablet, so that cable seems to be the problem.
