how can i display latitude and longitude with label (12 and 13) when screen is opened with LocationSensor
Try with a LocationSensor1.TimeInterval of 20000 rather than 1000. Set the interval using Blocks.
Get near a window. The LocationSensor usually takes 30 to 60 seconds for the first determination of where it is at (initiate a LocationChanged event). Be patient, the first posting of coordinates may take awhile.
