Hey guys. So, here I am trying to fly my spark indoors and noticed that when I pointed my phone camera in front of the drone the infrared sensor for the obstacle avoidance is not on ( even it is on in the settings and not in sports mode). So I tried to fly it close to the wall and it is not noticing that it's about to hit it. The radar like symbols are not showing on the dji go4 app. It shows for a bit when I toggled sports mode then back to normal mode but still doesn't notice the wall. Any suggestions on what to do?
