Hi Mi Fans!
The accelerometer is a built-in component for measuring the acceleration of any mobile device. Motions like swinging, tilting, rotating, shaking is detected using the accelerometer. The value of XYZ is used to calculate and detect the motions.
How does it work?
How to measure acceleration?
The accelerometer in the mobile device provides the XYZ coordinate values, which is used to measure the position and the acceleration of the device. The XYZ coordinate represents direction and position of the device at which acceleration occurred. The rotation direction and position are measured using gyroscope sensors that are found in the Android devices. The mobile device rest on the Earth includes the acceleration due to gravity (g = 9.81m/s2) and the acceleration value. The accelerometer values provided by the device normally includes the gravity as well. Accelerometer along with the linear acceleration and gyroscope will provide results close to accuracy. Linear acceleration does not include the gravity. The accelerometer value is passed into the low/high pass filters for refining the result, based on the application that has been used.
Sleep Tracking with accelerometer
The movement is measured relatively. This means that it doesn’t matter whether you are a tiny girl or a regular person. The app is always able to distinguish between ‘moving a little’ and ‘moving a lot’. Heck – it should be able to measure a fly sleeping on the phone! You always see the maximum of your movement as a maximum of the sleep graph and the same with minimums.
The accelerometer sensor/component is device-centric (according to manufacturer), so the accuracy of the acceleration values differs from device to device. So before building an application, you should have built your device with accelerometer by the same manufacturer. Limitations are there, but they vary based on environmental conditions.
Solution I - Take a CIT Test
Step 1: Open Phone
Step 2: Dial *#*#6484#*#* from the dial pad
Step 3: Select the option 28.Accelerator
Step 4: Place the phone on a plane level surface and click the Calibration button
If the test succeeds, the accelerometer sensor is working fine on your device. In case of error, Kindly follow the Solution II & III respectively.
Solution II - Factory Data Reset
Before performing a hard reset, please note the following
Solution III - Visit a Mi Authorized Service Center.
