Interviewers normally should not change any of the settings on this page, but may be required to do so based on the instructions of their supervisors or technical support.
Some combinations or values of these settings may cause errors in operation/synchronization. Change these settings only if you know what you are doing.
If you do make any changes compared to the default values, and you are requesting support from the development team, you must mention in your question, issue description, or the support request, which settings you've changed and which values you've specified.
Below is a brief description of these settings.
The default value is reasonable for most circumstances. If the interviewer is constantly receiving errors when trying to capture the location, this value may be increased to give the GPS-location sensor more time to determine the position of the device.
The default value is reasonable for most circumstances. Increasing the value may result in faster, but less accurate measurements of the location. Decreasing the value will cause the device to attempt to determine the position more accurately at the expense of longer wait time and higher chance of an error. Each GPS sensor has its own physical limit of accuracy. Specifying too low of a number here will cause constant or frequent errors in determining the position.
The default behavior is to show the captured location on the map if the tablet is online at that time. To save the traffic, this may be switched off and the map will not be rendered in the GPS location question, even when the tablet is online. This does not affect the capturing of the coordinates.
The default behavior is to indicate a new error during an interview with vibration (if supported by the device). This can be switched off and vibration will not be used even if supported. Note that most phones do support vibration, most tablets don’t.
This reflects the address of the synchronization point entered during the first login. This should only be changed if the actual URL of the same synchronization point has changed, otherwise the interviewer will lose the possibility to synchronize.
This is a display of the device identifier as reported by the Android OS. The supervisors, HQ and admin users will see this value in the interviewer’s profile. Device identifier doesn’t generally allow to understand what model is this device (such as Samsung Galaxy Tab 4) and may differ from the serial number of the device (the one you see on the box when you purchase it), but allows to distinguish one device from the other.
