I have an iPhone 8 and purchased the Robot bc the Amazon listing said it worked with my phone. It will not balance - period. I’ve adjusted every way I know how. When powered on, the motor attempts, but basically goes limp. I tried a friends’ iPhone X and it balanced right away. Maybe not perfectly, but it magically did as all the videos I watched indicated it would. Is there a magic setting I’m not aware of? Any ideas how to balance it? Thanks.
