-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}}.+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).
