Took this yesterday afternoon.
For some reason, my smartphone screen kept showing "Low radio signal" at the top left (I still have live view, and still be able to control Spark though). Flight record did not show this on the screen, so I cannot send to DJI for investigation. Anyway, so scared to fly higher than 20m and further than 30m with my phone....
Would appreciate if somebody know what is the warning about, and how should I react to this warning?

Try this. Turn off Bluetooth. Goto somewhere, let's say 1 km. away and relaunch the Spark.

Hi,
Thank you for the quick reply. Actually I always turn on airplane mode and enable only wifi whenever connect to Spark. However, I have this warning quite frequent lately. I am thinking of re-calibrate IMU and compass sensor. Not sure if it helps or not. But still, I am considering a remote control.
I only complain to DJI is that I bought the basic combo because I believe smartphone is enough, now I will have to buy a remote with totally as much as a combo already...
It was a bad decision for buying the basic combo, and DJI was also bad to release the basic combo before the flymore combo. They are supposed to release them the same time

Nice one keep it up

Nice shot - very vivid   

Cool, thanks for sharing!
