Displays the sensors supported by the device.
The Sensors page displays the sensors supported by the device and the current values of these sensors. Tips for testing the sensors are included on this page.
The display of the sensor type/name along with changing sensor values provides the first level of confidence of a functioning sensor. Some faulty sensors just have a fixed value that does not update.
Tips for testing the sensors include:
- Light sensor: cover the light sensor and check the value drops to 0. Move the device to a light source (e.g. a ceiling light) and check it increases (for example, a LED ceiling light at 1 meter may be around 300 – 400 lx). Also, compare with another phone’s sensor value.
- Proximity sensor: move a hand towards the proximity sensor. It should indicate, near or far, or an approximate distance (depending on the sensor capabilities).
- Pedometer: simulate a pedometer motion (e.g. 10 ‘fake’ steps – slow shake).
- Pressure: Compare the pressure value to another phone.
Generally speaking, if you place the device flat (on a desk) then:
- Accelerometer: the Accelerometer sensor should mostly not change, with the values being approximately x=0, y=0 and z=9.8m/s² (the force of gravity). This is the same for the gravity sensor.
- Linear acceleration: the Linear acceleration sensor should be the same as the accelerometer sensor with the gravity removed. i.e. x=0, y=0, y=0;
- Gyroscope: the Gyroscope sensor should show x=0, y=0, and z=0. i.e. no rotational velocity.
- Rotation sensor: The rotation sensor (measuring the orientation of the device) will normally be x=0, y=0, and z=<a value indicating the device orientation around the z-axis). For example, if you rotate the device anti-clockwise while flat on a desk, the z value should increase in the range [-1.0 .. 1.0], e.g. 0.2, 0.3 .. 0.9, 1.0, -1.0, -0.9, -0.8 .. 0.0, 0.1, 0.2 for a full rotation around the z-axis.
- Magnetic field: the Magnetic field sensor will change with variations in the magnetic field. These are normally small changes if not moving.
Opening the Phone Check and Test Sensor test on a second newish ‘quality’ phone will allow some sensor values to be compared.
Information about a supported fingerprint sensor and enrolled fingerprints is included at the top of the sensor list. In the in-app paid version, you can also test the fingerprint sensor.
Based on your checks, you should select OK, NOK or skipped
The sensor types supported will be included in the test report, along with the other device specifications.
