I recently received a 10" Asus tablet running Android 4.4.2. It is a cheap Tablet but it was free and runs all my Phantom apps great except for 1 thing. The Phantoms direction on the Radar in the Vision app is wrong. Its is ok on my LG G3 phone so I know its not a problem with the Phantom but something with the tablet.

Phantom Vision Plus v3.0  MCv-3.12
Tablet app is DJI Vision .apk 1.0.54
Phone app from Google Playstore

I found a video of this problem on youtube here


Here is a screenshot from the Tablet


Here is a screenshot from my phone in the same spot as the tablet


I downloaded a compass app and it looks like the compass is off on the tablet?

Tablet Compass App


Phone Compass App


Anyone know what the problem could be ? Is there a way to fix the compass on the Tablet ?

maybe that icon is showing direction phantom is "heading"  not a compass as per north/south/east/west compass

Thanks for the reply. When I am flying the phantom travels in a different direction the what the tablet is saying. It looks like the tablets compass is off and I wondering is there a way to fix it ?

I downloaded a app to fix the compass and now the compass app works and shows the same info as my phone but the Vision app is still off.

Did you try restarting your tablet after calibrating the compass?

I just tested Kenargo's app DJI Ultimate Flight and it is working fine on the tablet so I guess it's the fact that DJI's app is not compatible. (Like it says on the play store.

Yes, I may just use ken's app or get a new tablet. I'm sort of getting tablet fever now...

Any chance the app/tablet cannot distinguish between portrait or landscape mode?

I noticed when I enter Accelerometer Sensor Mode with the DJI app I have to tilt the tablet left and right to get the camera to go up and down instead of tilting the tablet forward and back. So I was thinking the same thing.

I went and picked up a LG 10.1" tablet to replace the Asus but this one has the same problem.

Does anyone use a 10 inch android tablet that will run the DJI Vision app properly?
I have a tripod, mount and hood for a 10 inch tablet so I really want to find one that works well.

Stocks,
I have a cheapie DOPO (Chinese) 10.1" Android tablet that has 4.4.2 KitKat as its operating system.
When I run the Vision App with this tablet the radar function does not show the correct nose "facing" of the Phantom...just like you documented.
In my case, the tablet does not have an internal compass function so I just assumed that any APP that requires compass calibration will not function with my tablet although everything else works with the Vision app according to spec.

It's because your tablets do not have gps function within the tablet itself and your not connected to 3or 4g cell provider. I have the same issue with my kindle but when I use my s4 cell the radar function works.

What about the 10 inch apple tablets, would they work?

Sjap. It says on both the Asus and the LG tablets that they do have GPS. I can also can turn it on and off in the settings. Also google maps show my location and the little GPS icon shows up at the top of the screen. Also if you look at the pics above it shows my GPS crod on both the tablet and phone. Also 3rd party apps like DJI Ultimate Flight  work. Unless there is somthing i dont know, i think the do have GPS built in.

Gerry. I wanted a Android just cause i dont have anything apple but I will get one if the radar works right. I know you have said before but what modle do you have and ios ver. ?

The reason it so important to me it becuase my controller is directional and when im 2 miles away it helps me to keep pointing the controller in the right direction.

Also, i have not tested this flying yet but sitting in the house it looks like my sons old 8" Android 4.0 tab is working fine. At lest the nose is pointed in the right direction.

Apple iPad 2 32GB, Wi-Fi + 3G (AT&T), 9.7in - Black (MC774LL/A)    Generation 2 now is upgradeable to 8.2 ios

Thank you Gerry. Do you have it activated with AT&T or is it deactivated and still works fine ?

I don't have any service with either one.  No sim card.  When I need to do any upgrades, I use the Bluetooth and connect to my home wireless network through the router, or you could go to any place that has wireless.

Thank you for your info Gerry. Shopping now

Update: I got a Ipad Air today and it works perfect.

I have the same problem. The quad knows which way it is pointing. It uses a yaw value. The problem is the electronics or metal in the remote control interferes with the compass in your tablet. I wave my RC around in a figure 8 while attached to the RC to recalibrate my tablet compass. This helps sometimes. Also my lanard has a metal clip which does not help.

I have the same problem too
Unfortunately I use a tablet Samsung S10 and it´s not compatible with DJI GO, them the radar does not work properly, I already calibrated the compass, but it did not work

As stated earlier, try an ipad if you can just to see, it will probably work as it should as stated in earlier threads.

On my Samsung S7 phone everything works fine:  in the "unlocked map view mode" the heading of the radar drone symbol and the orientation of the phone mounted to the RC are identical.
BUT: with my Sony Xperia Z4 tablet there is  a 90 degrees orientation mismatch between the drone heading and the tablet's orientation.
This fault indeed seems to be a related to the misinterpretation of landscape (Android tablet) and portrait (Android phone) display mode by the DJI pilot app. The result: the Google map (including the red arrow drone symbol) is always turned by 90 degrees to the left (counter clockwise) when using an Android tablet.
I notice that the DJI pilot app on my Samsung S7 starts in a fixed portrait mode (aircraft selection page) and than switches (by rotating right=clockwise) to a fixed landscape mode automatically.
Is it possible that a suppressed clockwise display rotation on Android tablets leads to the map view being completely locked in a "virtual" portrait mode?
I really searched many threads for an answer: most stop without a solution or they say that an iPad is the only help...

Which brand(s) do you have?

Most are fine.
I've used the Nexus 7 (2013) and Nvidia Shield and never seen that problem.
Not sure if it's the tablet itself or something in the settings.
