Updated the app then updated firmware on Air 2 to 340 no problems. Noted the changes, checked safety, control, camera , transmission ( had plenty of satellites indoors near window), thought would take off and just hover. Air 2 veered to right , hit wall and shot off forward and left into bedside lamp splitting front left prop . It did beep ,obstacle avoidance front sensor ? just before it veered to right initially but I can't be sure, all happened so quick! Camera was not working but app off, Air 2 off and all back to normal with restart. Thinking about it, after update, avoidance was automatically set to BYPASS and no sideways movement so presume it detected wall 2 metres in front and tried to find way round ? I recalibrated compass and EMU (?), turned off obstacle avoidance then rehovered and all ok. So be careful folks inside in smallish rooms - I know, I'm an old idiot but updating inside with wifi then hovering seemed the right thing to do so do tell me what I did wrong. Wonder what would have happened if I had been outdoors , all ok or even worse? I have been lucky, one prop damaged.
