After update my obstacle avoidance is not working ????? I need help

Mine worked as it almost flew into a tree.  I was so impressed and happy

Obstacle avoidance also works fine for me after the firmware update with an ipad.

obstacle avoidance will show its off until you take off

Firmware change - not necessarily for the better.  After take-off it works again

Hi there, thank you for reaching out and we're sorry to hear about the trouble you facing, Regarding that It is normal that the sensing icons on DJI GO 4 Android are all red when the aircraft does not take off, as the aircraft can detect obstacles. This is a normal condition, and the sensing system is not affected. This will be optimized in the next firmware version.
