I use a Nexus 7 II tablet to fly my P3A with DJI Go app.  It all works fine, EXCEPT I can't get the 'follow me' mode to work.  POI works fine, though.

I'm pretty sure the Nexus has a GPS chip, and ought to work with follow me.

Does anyone have any experience of using this tablet with follow me, and if so did it work for you?  Are there any settings I have missed that I should change to get it working?

Thanks in advance.

The GO App integration with the various mobile devices can give varying results for follow me as the device must provide adequate signal to locate the RC and provide follow-me feedback to the P3.
With any IOC activity, always ensure your RTH is set appropriately. On your mobile device, prior to aircraft launch, you can use one of several Play Store apps to verify your GPS strength:

AndroiTS GPS Test Free
GPS Data

Follow Mode definitely works with the Nexus 7 (2013). Of the 3 tablets I fly with, my Nexus 7 is the oldest, yet also provides the best experience with DJI Go. I have used this tablet (it DOES have GPS) for Follow Mode on the Phantom 3 Standard as well as the Professional. It's so solid in fact that I trust my kids with the controller. What happens when you attempt to use this mode and what are your steps to accomplish it?

If it's a device recommended by Dji, as the Google Nexus 7 II is, are you saying it still may not work? If so, where does that leave people who are looking for a device, they don't come cheap

Given that the device has a functioning GPS module and acquires/maintains sufficient GPS data to determine its location, then the device will work.

But there are scenarios that become troublesome:

DJI recommended devices may or may not include internal GPS modules capable of supporting these functions. For example, Wi-Fi-only iOS devices do not include GPS. You must buy the cellular version for inclusion of the device GPS. Some DJI recommended devices include 'Assisted GPS' that allows the device to retrieve some of the GPS data via the mobile network, so these type of devices when operated outside cell tower range, or purchased as Wi-Fi-only won't provide the needed data since they won't have the necessary mobile network connectivity to determine location.

There are some flight locations that might block GPS signals to the mobile device such as those filled with city high-rise buildings, trees, or mountainous terrain.  

The Nexus 7 II has full GPS support. So given that the pilot's location has and maintains suffcient GPS satelite connectivity to the device, then it should definitely work.

Sorry for the misleading response.

Do you use DJI GO 3.1.2 ?
If so, just search internet and playstore for follow mode and 3.1.2. - you will find many since 18.1.2017.
To me it sounds that this could also be related to the new gps bug in Go!

P3S, latest FW, Nexus 7 2nd gen, DJI GO 3.1.2. Android

Do you have the cellular one i.e. SIM in it? Dji say it isn't required but recommended

No that's a good response. I am fairly technically minded but I find some of this very confusing and the manuals are not much use. So, to be clear before I go out and buy a device that I didn't realise I needed - the Google Nexus 7 2013 second generation should work OK without a SIM in it, as I don't want to use it as a phone or have a contract just for this?

Correct. You don't need the SIM card or data contract for the GPS to provide location data. You may need to cache maps over Wi-Fi prior to flying.

Hopefully, thegrindlab or Formentera can/will confirm if you even need the cellular model as I believe the Nexus 7 gen 2 has GPS in both Wi-Fi and cellular models, but I only have the Samsung Note 4 and two iOS devices. Both of my Apple devices are cellular so that the GPS module is included, but neither have SIM cards and they work perfectly.

Thank you, I wish I had got such a good response from the Dji support live chat ;-)

As far as my experience goes, i could fly flawless before 3.1.2.,  without downloading /cache google maps for nexus gen2. You do not need a sim.
As far as i know DJI GO only uses the data of the gps module of the nexus 2 or any phone/tablet and not google maps - but that is only what i think.
After my bad experience with 3.1.2. i also downloaded maps to check my "real" position on google maps or navigator.
As i mentioned before: to me the problem is part of the gps bug - assuming you use 3.1.2.

I have a Nexus 7 II and had issues with it. Haven't tried the follow me, but was having issues and couldn't figure it out. SO I uninstalled the DJIGO and re installed, been working great ever since. Hopefully I can get out on the weekend, I'll try the follow me and let you know

No. I do sometimes have it connected to my mobile phone via WIFI though. The data connection is not required for solid GPS services at all though. I only used it so satellite images are downloaded as I fly.
