Can anyone recommend a tablet or smart phone that is compatible with the P4's "follow me " mode.
I had a P3 that work well with a Lenovo 7" untill they updated the software, then only my Samsung GS6 would work in "follow me " mode.
Now nether works with the P4's fm.

As I understand it, your asking the wrong question. If i'm getting this right, the "follow me" feature uses cellular signal, which the "Active Track" feature uses GPS and sensors. I was told by a DJI rep that basically unless i bought a tablet that has 3G or 4G or an ipad with cellular capabilities I couldn't use the "follow me" feature. He said I shouldn't worry though, because I could use the "Active Track" feature and that basically AT blows FM out of the water.

Hello, here is the compatible devices list. If you need the FM function, it would be better to buy a tablet with GPS module like cellular iPad series below

iPad Air 2 64Gb Cellular... It's a dream device.

The Follow Me mostly depends on the environment and device GPS signal strength. If it doesn't work, the APP will prompt up a message on the screen

That was true of the P3. But I get no prompts on the P4. I would like to know if anyone has run the FM successfully and what device they used.
