Altitude or barometer is inaccurate on Samsung smartwatch
![](https://image-us.samsung.com/SamsungUS/support/solutions/mobile/wearables/smartwatches/WRBLS_GW_Altitude-or-barometer-is-inaccurate.png?$support-tsg-hero-png$)
Your Samsung smartwatch's pressure sensor can calculate altitude and barometric pressure, but it requires calibration to work correctly. By default, the sensor will automatically calculate the altitude and barometric pressure based on the watch's location. The Manual calibration option can also calculate these if the automatic calibration fails.
