Attention: If you cannot install this application, it means your mobile device doesn't have an accelerometer sensor or a magnetometer sensor. You may be interested in another application which is called "NoteCam." However, NoteCam doesn't include pitch angle information, azimuth angle information, and a horizontal line.

■ If you have a problem with the coordinates (GPS), please read the instructions below.
An App receives the coordinates sent by Android, if
□ Unable to capture coordinates: This is a problem with the mobile phone, and has nothing to do with the App.
□ The positioning speed is slow: This is also a problem with the mobile phone, and it is also related to the positioning method. However, it has nothing to do with the App.
□ Cannot catch altitude: This is related to the positioning method and has nothing to do with the App. Network positioning may not have an altitude value.
□ Poor accuracy: This is related to the positioning method and has nothing to do with the App. Please understand that Android provides "accuracy" value because the coordinates are "inaccurate". Large values may be normal.
■ There are two positioning method.
□ Network positioning (indoor): A-GPS, the accuracy can be large. If the value is less than 3000m, the accuracy is normal.
□ Satellite positioning (outdoor): Satellite GPS. The accuracy should be small. If the value is less than 300m, the accuracy is normal.
