I tried to calibrate the flip camera as per the direction given in settings.but it failed every time and trust me i have done many times.. In vertical calibration it's fine but in horizontal calibration it usually fails in 2nd ..iteration (as u noe for calibration it takes 3 iteration in horizontal and vertical.) i have attached a screenshot for u to understand the problem. please let me know if any one of you have any solution for this except factory reset.
