Now the automatic recording on my Galaxy Tab S 9 of my Mavic flights on video and my flight records in the Go4 app are missing ... I accidentally let it update the Android system after I had booted to fly ... and now I'm screwed. Don't think you can roll system updates back? Or am I missing something? It's still on the Mavic chip .... but it not longer let's me view my flights on the Samsung .... I've about had it with these "so called updates" that almost always break what was working fine before.
