Hello everyone, I am new here so i hope i am posting in the right place, So i got my SGS2 last month,i love it,everything seems to be fine,i was learning tips and tricks everyday and loving it more and more,but then i noticed that in all the youtube videos when they rotate the phone,screen would rotate automatically,everytime,and mine didn't do that much frequently,it had like its own will and it would rotate sometimes and sometimes it would not,since i wanted my qwerty keyboard in landscape mode so i started looking into it,(the auto rotation was turned on) First thing i found was horizontal calibration,tried it,it will go on for hours with out saying "calibrated" i finally had to take out the battery to switch off the phone and then re start it,with no different results. Then i found *#0*# test,tried that,first the magnetic sensor was moving had a blue or a green line on it and i think number "2" was written on it,i read that when i rotate the phone the x,y,z readings should change ,but they weren't ,i tried image test and after rotating phone for a few times the values started changing and the image rotated,i went back to home screen and text screen also rotated and i was happy,but then after half an hour or so i picked up my phone and it again wasn't auto rotating,i did *#0*# again and this time magnetic sensor had green light on and number 3 and it was moving but when i did the image test it didn't move at all. So finally i thought i need to put it for calibration again no matter ho long it takes,i did it again,took hours and hours all my battery was drained,and when i plugged it and re started,auto rotation was totally gone and now when i do *#0*# the sensor has a red light saying "need for calibration",accelerometer sensor has no readings and gyro selt test says "FAIL" (i don't even understand whats gyro selt test :s ) I am really freaked out here,did i damage something? plz plz plz help me,i tried reading through the forums but half the lingo i don't understand ,plz be easy with the language,i am begging for help,my family was really not happy i got this expensive phone,and now if something happens to it sorry for the long post,i'll anxiously wait for replies.
