I'm using a Mavic 2 zoom and my phone is iPhone 8. When I'm trying to set the home point to me on the app, it doesn't allow me to do that because it says GPS signal too weak on my phone. I've tried this in different locations as well but it gives me the same error. Does anyone know why?

The home point is set once the motors start. If I understand you correctly.

Why are you using your phones GPS?

I haven't tried this yet, but read it here somewhere.  When you start the motors and BEFORE you move the craft, swipe the screen of your tablet/phone to the left and it will brighten the screen and set the Home Point.  Might give it a swipe, like I said, I have not tried it yet.

Hello and good day CharlieZ. I am sorry for the inconvenience. Have you tried a different recommended mobile device to test if the issue still persist? Actually, it is not recommended to fly the drone when there is no GPS, I recommend you to choose an outdoor open area where the GPS is good and no magnetic interference to fly the drone. If there is any further issue, please feel free to let us know, we're glad to help.

This is well known with iOS devices. Thought this had been fixed.
Just for those that don't understand the problem,

it is this command which you are using and then get this

The is no easy fix for this unless Dji will do something about it.

Yes this was fixed but after another update 3 weeks ago it now fails to work, i once thought it was my iPad mini that was at fault but i have seen it work with an update, last update killed it

Just a guess...  But you might check if your Apple device is allowing DJI Go access to the GPS function.   I have mine set to "While Using".    Not sure how this would work with a non-cellular iPad which doesn't have a GPS receiver.   Below is a screen capture from my iPad Pro 9.7

Hi drone pilots

I own a mavic 2 zoom and every time I try switching between home point to the little man which means it’s supposed to land where ever you are standing with your controlar , it says it can’t be changed due to weak gps signal on my device, I then did the same with my iPad Air which has cellular and WiFi and still it would not let me ,saying the same weak gps signal

Same issue when changing home point setting with my ipad air 2 says weak gps signal, dji engineers have been aware this is an issue thats not been corrected so must be a latent defect they should either eleimanate the option and/or disclose the problem they cant fix

I just tried two days ago and it did not work. The DJI Go4 apps actually showed 19 Satellites available at the time. Do we have any DJI employee here to acknowledge the problem and tell us when it will be fixed.

The number of satellites being reported by the DJI Go 4 app are those visible to the aircraft, which has it's own GPS receiver, it has nothing to do with whether your Apple device can see satellites or not. The aircraft will ALWAYS set the home point when it is started up, and the motors are started, as long as it can see satellites. It is NEVER WISE to fly away until you hear confirmation that the 'Home Point Has Been Set'.

If you wish to set a new home point to your RC control unit position, then the RC unit will try to read the position from your phone or tablet, but if it cannot get a good GPS signal from the phone or tablet, then it will not set a new home point.

Apple devices have to be instructed in the settings to use Location Services and also to make that information is available to connected devices, and Apple devices that do not have a cellular connection HAVE NO GPS AT ALL, as the cellular chip and GPS receiver are all in the one chip.

Be aware that if you have the RC device in a vehicle, house or under a roof, the phone will most likely not have a suffiently strong enough signal to set a home point.

It would be unrealistic to expect the DJI people in this forum to do anything other than fob you off with the usual  meaningless copied & pasted answer.
The issue has been happening for two years now so it's probably not going away anytime soon.

The issue has nothing to do with the number of satellites available (there are always more than enough).
It's also not about the Apple device not receiving GPS data from the sats.
It's something that prevents the app from getting the information from Apple devices.

I'm now aware of the difference of the gps satellites reading for the drone and for the phone. I also read this from other posts. Thanks.

However, my cellular connection at the time was strong (full bars), my WIFI also was one. No luck.

I read a post from two years ago that if you unplug the wire connecting to the phone and plug back when the controller is connected to the drone, it could fix the problem. I have not tried this yet.
