 **Loss of the GPS signal**\\ **Loss of the GPS signal**\\
 A common issue when recording a track is the loss of the GPS signal, leading to a missing part in the recorded track (seen as a straight line longer than usual). It usually happens because the device doesn't have a good enough access to the sky, for example when the device is placed in a deep pocket or in a bag. The GPS signal emitted by GPS satellites is weak and get easily lost when going through any material. If you have checked "**''Warn me if the GPS signal is lost or too weak''**" {{:icon_03.png?nolink}} option, the application will play a song when this happens. A common issue when recording a track is the loss of the GPS signal, leading to a missing part in the recorded track (seen as a straight line longer than usual).

 +**Recorded track doesn't precisely follow my real locations**\\
 +Some devices perform better than others while using the GPS, depending on the quality of the hardware used and internal conception (location of the GPS chip inside the device). Some devices require a stronger GPS signal to give an acceptable accuracy. For example, here is the same track recorded at the same time by two different devices (one in the left pocket, one in the right) during a small outside walk with occasional stays inside buildings. We can see that the Samsung S9 {{:icon_01.png?nolink}} performs better than the Huawei P10 Lite {{:icon_02.png?nolink}}.
