DJI osmo mobile 2 read DESC

Dji osmo mobile 2. When the phone is on it it moves around a lot. It doesn’t lock into place. I’m not sure if it needs to be recalibrated or what needs to be done. I also keep getting a message saying “reboot osmo mobile”. That message keeps popping up. I’m not sure what that’s about. Also, it blinks yellow. I don’t know what’s going on with this thing. It once worked and then all of a sudden started with that message and blinking yellow. It charges great still. Maybe someone can fix it and use it. Maybe it’s a simple fix. I’m not sure. I’m not tech savvy when it comes to these things. I may have missed something minor. Ask any and all questions and I will try to answer to the best of my knowledge. NO CHARGER INCLUDED. NO RETURNS. COMES AS IS.
