From UBIK 4 onwards, the camera calibration can be done directly on the device. Navigate to Settings -> AR and locate the section ''Camera Calibration''. Right of it there are 3 buttons:
== Start calibration (Camera symbol {{key press|Android}} {{key press|iOS}} ) ==
[[File:CamCal Checkerboard.jpg|thumb|220px|Calibration in progress]]
Return to the settings screen. You will now see text stating ''Device calibrated as [model]'' underneath the ''Camera Calibration'' label. Your device was successfully calibrated.
== Export calibration (Download symbol{{key press|Android}} {{key press|iOS}}) ==
Exports the currently stored calibration of this device into a text file, that can be used for import on other devices of the same model. The resulting file will be presented in a share dialog.
== Import calibration (Upload symbol {{key press|UWP}} ) ==
The native UWP client does not have the built in camera calibration feature, but it can import calibration files that were previously generated and exported from other clients.
