After latest firmware (01.00.0500) update & latest DJI Go 4 App update (4.1.5), I noticed that range seems to be improved. I decided to do a test from a multistory parking (to get a better VLOS) using OTG vs WIFI.
To my surprise, I got best results (1.2 miles / 2KM range & a perfect signal score of 100) on 5.8GHz WIFI as compared to similar flights I performed using OTG cable and switching manually to 2.4 GHz channel.
I was using my old iPhone 5S in airplane mode for all these flights (only wifi enabled for 1st & 3rd flight).
I am thinking that leaving frequency selection decision to Sparky for best results and ditching the OTG cable as well hereon.
See the results here:
1. Flight on 5.8 GHz WIFI: 2KM & Signal Score of 100
2. Flight using OTG with WIFI off: 1.6 KM, Signal Score 42.9
3. Flight with 2.4 GHz channel selected manually: 1.6 Km & Signal score 27.6
