Anyone else’s inaccurate? app says i’m brushing one side of my mouth when i’m actually brushing the other. for a $300 toothbrush this is unacceptable

Remember to run it across your teeth gradually, not brush like with a manual toothbrush. That should help with the accuracy. The toothbrush has a sensor in it for which angle it's in and how your holding it.
