Hi Hani
As someone who uses both Android and iOS with a Spark I hope I can put your mind at rest.
One of the big drivers for us European Android users for OTG support was the fact that Euro Android devices could not access the 5.8GHz WiFi connection from the controller. This meant that the performance/range was severely limited as we were forced into using 2.4GHz connection between device and controller and relying on the very low powered (25mW) 5.8GHz link from controller to aircraft. Using the OTG cable meant we could use the more effective 2.4GHz link for the controller to aircraft link. It also dramatically reduces the latency and frame dropping of the video downlink.
For some strange reason the majority, if not all, iOS devices in Europe have access to the controllers 5.8GHz WiFi connection. This is probably why DJI push iOS users to refrain from using an OTG connection. I’m currently using a 2018 6th Gen (128GB) iPad with my Spark, with next to no other APPs installed, and I still notice a dramatic improvement in the quality and reliability of the video downlink when I use an OTG cable. The reason why the “THIS DEVICE IS NOT SUPPORTED” message appears is because Apple, being the typical control freak company, don’t like owners using “their” lightning connection for off label purposes.
The only possible downside to using an OTG cable is a loss of the downlink info if you accidentally pull the cable from the controller while in use. This isn’t as terrible as it sounds as you’ll still be able to control the Spark, pause it in flight while remaking the connection or initiating RTH if things get really panicky.
Regards
Nidge.
