Today my Note 4 fell out of my pocket from ca 1m, luckily on a carpet with a case on it. But since then my G Sensor is broken (?). My phone always thinks that it is upside down. I downloaded Labyrinth lite and calibrated it, but it isnt moving when i tilt it up and down. Left and right is working fine. Is there any way I can calibrate it? Because there are no settings for calibration in the settings. I dont want to send it to Samsung because I cant stay without it for 2 weeks...
sorry for the potato english
