 In recent Android versions, multiple optimization tools have been added in order to reduce battery usage, especially targeting background applications. For example, the "​Doze"​ mode will stop all applications on your device when your screen is turned off for some time. In order to correctly record tracks even when your screen is turned off, you need to disable those optimizations for the application. In recent Android versions, multiple optimization tools have been added in order to reduce battery usage, especially targeting background applications.

-**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).

-**Device gets hot**\\+==== Recorded track doesn'​t precisely follow my real locations ==== 
 + 
 +Some devices perform better than others when using the GPS, depending on the quality of the hardware used and the internal conception (placement 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 Galaxy S9 {{:​icon_01.png?​nolink}} performs better than the Huawei P10 Lite {{:​icon_02.png?​nolink}}.
