Hi guys - newbie here. 1 week in with a Phantom 3 standard. All seems to be ok physically with the drone but the range is really poor. Probably 100m or less before it loses signal and flys back.
I've flown it in 3 different locations (although in the countryside in the UK) and on P mode (top setting on left-hand rocker switch).
I'm using an iPhone 10s max with the latest firmware.
Apologies if this has been asked before.
The P3S is not a long haul drone. Nevertheless, your range (about 328 feet) is not normal. Speaking from experience, I had the same issue a few years back. I worked with DJI support and ultimately sent it in for a look under the hood. They replaced the entire main board and sent it back to me the next day. Has flown great ever since. Furthest I ever sent it out was about 1200 feet (about 366m) and I still had a strong signal.
Beginner mode comes to mind, however, I don't recall if the distance is fixed or not. And if it were, I don't think that triggers the return to home. To be sure, open your settings in the GO app and check beginner mode. I think there is another setting for maximum range. Never tried it so I don't know what to expect if I ever hit it.
Other possible causes are broken antenna either inside the controller or the drone.
One other thing you can do that would help is upload the flight logs. I'll post a link to phantomhelp dot com where you can upload the logs. Just follow the instructions on the page. Then copy the link and post it back here. Most of it is fairly straight forward. The complicated stuff can be deciphered by some other people on this site.
