I have flown my mavvie quite a bit indoors with solid stability and in tighter quarters than your room without any errant action. Did you have the controller in beginner mode ? Switch on the right side of the controller in normal mode (the slider - mine came out of the box slid towards SPORT mode) and in the app confirm it was in beginner mode ? For it to go into the wall would mean obstacle avoidance was not on. I know that the obstacle avoidance which is camera based disables in low light conditions as I got that warning once indoors and stopped flying. I have tested the obstacle avoidance and it will not fly into a wall and it appears yours did so I would be curious about those settings first. A bit of a Christmas morning letdown !
