## Tested Barometric Sensor Smartphones
There are smartphones that have a barometric sensor that OpenTracks uses to compute altitude gain and loss.
OpenTracks derives the altitude gain and altitude loss using the internal barometric sensor of a device (if present).
However, barometric sensor seem to be prone to a lot of noise.
This may either be a malfunctioning sensor, a case that prevents the device from measuring, or something else.
In our tests there are smartphones whose barometric sensor works well and others don't. Here is a list of the smartphones tested:
To check if the barometric sensor of a device is working with OpenTracks:
1. Record a track (ca. 1min) with the device stationary.
Expectation: 0m gain and 0m loss should.
2. Record a track (ca. 1min) while shaking the device.
Expectation: 0m gain and 0m loss should.
3. Record a track (ca. 1min) while moving the device up (less than 3m difference between highest and lowest point).
Expectation: 0m gain and 0m loss should.
4. Record a track walking up some stairs or taking an elevator.
Expectation: some gain and some loss is recorded that seems realistic.
| Brand | Model | Android Version | Tests |
|--------|--------------------|-----------------|--------------------------------------------------------------------------------|
| Google | Pixel | LineageOS 17.1 | Ok |
| Google | Pixel 2 XL | LineageOS 17.1 | Ok on the bike handlebars but it fails when I carry it in a pocket or backpack |
| Google | Pixel 3 | Android 11 | Failure |
| Google | Pixel 3a | Android 11 | Ok |
| Google | Pixel 3a | Lineage 18.1 | Ok |
| Google | Pixel 4a | Android 11 | Ok |
| Sony | Xperia XZ1 Compact | LineageOS 16.1 | Failure |
If any of these tests do **not** show expected values for gain/loss, OpenTracks will not show useful values.
Please note that OpenTracks:
* only records gain/loss if +/- 3m to the initial/previous of are measured to the previous
* solely uses the barometric sensor for gain/loss; GPS is not used for this.
In our tests there are smartphones whose barometric sensor works well and others don't.
