The follow-me system isn't perfect - yet. Follow me works by following the GPS in the smart/phone device. The only draw back is the device is physically connected to the remote and therefore visible when followed. The solution is to wireless "tether" the GPS data to another device.
I have briefly tested 3 methods:
1. Litchi and Magic Leash (Android only).
2. Go App and Holux 236 External Bluetooth GPS
3. Go App and additional Android device - BEST!
All 3 methods work but have limitations.
1. Litchi and Magic Leash.
Difficulty - 2 ninjas.
Litchi Magic Leash - Android Apps on Google Play
I tested this on 2 android Lollipop samsung Note4 devices. Litchi pilot app cost $15 and the Magic Leash is free. Litchi is android only and Magic leash is android (and soon to be released IOS).
I won't go into detail with the Litchi as there is threads already. Magic leash works by connecting to a server. This is paired by a unique random 4 pin number. It requires 3G/4G data services.
Pros:
Difficulty - 4.5 ninjas.
Using a class 2 External Bluetooth GPS device required some tinkering.
You need a Bluetooth GPS app installed on your phone and you need to enable Mock Locations in the USB debugging mode.
Bluetooth GPS - Android Apps on Google Play
The app will force/trick the phone to use an external GPS.
Pros:
3. Go App and additional Android device.
Difficulty - 3 ninjas.
This is my favourite option. Its a little confusing at first.
Using an app called TetherGPS (lite version has 5 min sessions and dies after 200min, get the full for $2). The TetherGPS app simply sends GPS data via the wifi.
TetherGPS Lite - Android Apps on Google Play
I used a throw away android phone as the secondary-followed-device (no data or sim required). Both android devices will require "Hotspot and tethering" via wifi.
Install the TetherGPS app on both devices.
Start the wifi hotspot on the secondary device that will be followed. Start the TetherGPS and click Start Server.
Now on the device connected to the controller, connect to the wifi hotspot. Start the TetherGPS and click Start Client.

Pros:
- excellent range (limitless provided you have data).
- light and easy app to setup on android phone.
- Requires data network.
- Average 300-400ms lag.
- Litchi is not free.
Difficulty - 4.5 ninjas.

The app will force/trick the phone to use an external GPS.
Pros:
- No data plan is required and works anywhere with an open sky.
- No lag. (The lag is with the DJI GO app resetting home point).
- Cost about $50-$100
- Poor range. Device is a class 2, range is 10m (33ft)

Now on the device connected to the controller, connect to the wifi hotspot. Start the TetherGPS and click Start Client.
Pros:
- No lag (except by the goapp)
- Use anywhere.
- Est 50-70m range (depending on wifi interference)
- No data plan required on followed device.
- TetherGPS cost $2 (im sure there are other free apps, I like to support devs).
Cons:
- If the followed device does not have data, then please cache map first.
