Changes
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]]
== Export calibration (Download symbol) ==
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 {{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.
== Delete calibration (Trash bin symbol) ==
