Hi ksmusa,
Thanks for the response. I guess I will have to wait for the official release. No big deal but I would really like to use an OTG cable with my Spark. I will continue using WiFi when using my Spark and an OTG cable when I fly my Mavic.
Hopefully Moverio will chime in an give me an estimate of when Epson will release 4.2.12.
I see you are in Carmel, CA, I am in Morgan Hill, CA. Have a great day.
Thanks again, ~Bill
