Had my Air 2 for about 4 years and went to first a Samsung A7 about three years back. That worked well for about a year and then seemed to get dropped by DJI Fly. Went to an A8 a year ago, and it worked great until the last Fly 'upgrade'. Now it's not usable with ANY DJI app. Looking at their compatibility list, there's no Android tablets listed as compatible, and not even iPads are supported anymore. My phone is a Galaxy S10 and while it works with the older version of Fly that's on it, I'm seriously not going to upgrade it as it's also not listed as 'compatible'. Is this something to do with needing a GPS in the device being used for FAA purposes? I thought the controllers had one.
