Beginner mode ?
Or maximum altitude / distance to be checked.

For the frequency selection, I read that it need to be first set using wifi, but I have not checked that.
I got also 5.8 GHz by default and had 600 distance flight, in CE mode,. not FCC, so was not too bad.

Are you getting any sort of message when you hit the 100 meters? Or is it doing a RTH?

Yes, correct, was written "attitude" but I should have guess it was "altitude".
No special flight mode like follow me?
If it happen again I would try to reinstall the GO app. Are you on android or IOS?

Antenna is up. I tried it first with otg cable wifi is on 5.8G if i tried conection phone with wifi i see i two wifi 2.4G and 5.8G but if i tried to change it i couldn't. I am happy with max altitude 500m is more than i was hoping but distance is just 100m.

The distance is really strange for normal flight mode.
I would try re-installation of GO4 app and also refresh the firmware using the DJI Assistant 2 software. That could reset some values to default.
Can you repeat it and it is always 100.0 meters or like 90 / 110 m ? If you move to a totally different place, will it be the same distance limit.

Less probability:
Could be bad luck and you are hitting a NFZ that you don't see on the app.
It is a new limitation by DJI (but would mean no GPS or no login on DJI server).

Just out of curiosity, find an open field and try to fly with just the remote or borrow an IOS device.

By rights the phone/tablet should have nothing to do with the range once an RC is being used, but from a troubleshooting perspective its always good to remove a variable from the equation. Plus Android does suck with DJI products

Hey guys, so i took spark for another spin this time on totally open place, got better distance 300m then lost signal still not really impressed. Just find out how to switch from 5.8G to 2.4 so have to try it tomorrow if i will get even better distance. FYI: first connect via wifi, then switch to 2.4GHz, turn phone to offline mode (flight mode) and connect via OTG.

Good you try it. Seems by me that android goes to 5.8G by default but my iPad goes to 2.4G. Where in wifi mode, the android cannot see 5.8G (3 bips needed) but the iPad see both (2.4G and 5.8G). At 5.8G with android I was getting 600m.
At least there is a workaround to use 2.4G with android.
