Since I know about the known issue of Hero G-sensor not able to save the calibration. I waited till I get the 2.1 hoping this will fix the issue. Right now. Nor does it not fix the issue I cant find the option anymore ..... Bubble calibrates and remebers okay. But those apps like google sky or teeter arent affected by that.... Some apps have their own calibrations like bubble - works well or papijump. But abduction with its own calibration wont work... Suspecting that google sky map and others wont work either ... Anyone happy with 2.1 (+ more issues in this forum) like me? And anyone know where i could find the setting in 2.1? Am either blind or its not there... The advice with the tapping and turning and tapping etc did it work for anyone?
