A mobile device cannot wreck the drone on its own. The only difference the mobile device makes is how smoothly it runs the DJI Go4 app which gives you live camera view and telemetry data while flying. Yes, based on user feedback, it can be said that iOS devices work better in comparison to their Android counterparts. Many also say that iOS devices do not need OTG cable for a smooth live view. They are useable with WiFi alone. Androids on the other hand give a very choppy live view with WiFi alone. I am an Android user too and use an OTG cable all the time. I have never had any issues with the sub $150 Moto E4 Plus in my 6 months of flying. So I suggest you buy an OTG cable too for your device and see for yourself how it performs. Welcome to the forum.
