| In addition of being closed by the system as seen before, some "device/memory cleaner/booster" applications automatically kill background processes. If you use such applications, be sure to add the track recorder service in the exclude list of your cleaning application so it doesn't get killed. | In addition of being closed by the system as seen before, some "device/memory cleaner/booster" applications automatically kill background processes.

| 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}}. | 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).

| Tracking a path requires frequent GPS location updates and some devices (mainly old or low-cost ones, but not always) doesn't support the GPS being turned on for long hours. Common symptoms in this case can be: | Tracking a path requires frequent GPS location updates and some devices (mainly old or low-cost ones, but not always) doesn't support the GPS being turned on for long hours.
