Tested the setup with my ipm4 connected with otg latest go4 app.  The video latency is very bad did a test and the delay was 2.5 secs. Then tested by connecting ipm4 via WiFi with the rc not much of a difference still within a 2sec range. Then connected my other device s8 via WiFi with the rc and had excellent video connectivity. I ve been using my s8 primarily before today my gf got me an ipad4mini WiFi only yesterday. Any suggestions would be helpful thanks

I am using IPad Mini 4 128G WiFi + cellular all the latest Go4 and IOS versions and the latency is barely noticeable with either OTG or WiFi. I know everyone’s experiences seem to be different across all platforms, My IPad is dedicated to the sole purpose of Drone Device, the only other things I run are video editor, 107 test prep, and Kittyhawk.

mine is too as well nothing else. it seems possible, was just relying on the ios to perform better than my s8. thanks for the comment  

As it is now my Ipad 4 mini is useless. It disconnects all the time
Only my Galaxy S7 with GO4 V4.1.15 and OTG seem to provide a stable connection.
