Hoping someone can help me out with an easy fix...
My Controller nolonger allows me to use the “sticks” to control flight; I can only use on screen control circles. Is this an easy fix?
Thanks.

Power on the Spark, then Press the Power Button for 3 Seconds until you here 1 Beep so you activate the Remote Control. Right now you have the Phone Activated with the Virtual Joysticks.

I am sorry to know what happened to your DJI Spark's remote controller. Try to relink the DJI Spark AC with the RC. Please follow the steps provided above 2#. Thank you.
