Below you find problems and issues applicable for Android devices.
On many Android devices, power management settings meant to extend your battery life can interfere with your app functionality. This is especially the case for apps that need to run in the background while the screen is dark (sleep mode). If you’ve been experiencing issues with the track stopping or have had your app crash while tracking, check the "Power saving" settings and "Battery Optimization" settings on your phone. The solution to most of these problems is to turn "Power Saving" to OFF.
Update Oct 2018
Android 8 (oreo) has introduced "background execution limitations" and made it increasingly difficult for apps like LTW to keep it's tracking services running when the screen is off.

Issues with Battery Optimization (Doze) - Heavily affecting Android 8 devices
Newer Android versions have a feature called "doze" which put apps in deep sleep when the screen is off. This prevents apps from doing stuff in the background, like sending data or receiveing signals. See below on how to disable "Battery Optimization" for some of the common devices (Android 6 and higher).
Phone settings – Applications – Select three dot menu (Top right corner) – Select ‚Special Access‘ – Select ‚Optimize Battery usage‘ – Find LocaToWeb on the list and make sure that it is not selected.
Phone settings -> Select 'Apps' - Select 'Advanced' (At the bottom) -> Select 'Ignore optimisations' - Press 'Allowed' and select 'All apps' - Find LocaToWeb on the list and set to 'Allow'
Phone settings -> Power -> Battery optimization -> Tap Not optimized > All apps (to see the complete list of apps)
Tap LocaToWeb and then tap Don't optimize > Done
Phone settings – Select ‘Battery’ – Select ‘Battery optimization’ - switch to the ‘All apps list’ (Top menu) – Select LocaToWeb and choose ‘Don’t optimize’
Phone settings - Additional Settings - Battery & performance - Manage apps' battery usage - Choose apps and select LocaToWeb.
Also, please go to your phone Settings - Additional Settings - Privacy - Location.
Check that you are using High Accuracy for Location Mode and also allowing location access.'
Configure app so it can use GPS in background.
Phone settings -> Select ‚Battery‘ -> Select the (...) menu in the top right corner and press ‚Battery optimisation‘ -> Select ‚Apps‘ -> Select ‚LocaToWeb‘.
Phone settings - ‘Battery & power saving’ – Select ‘Battery usage’ – ‘Ignore optimizations’ – Turn on to ignore battery optimization for LocaToWeb.

There are many other smaller brand smart phones available that use Android, these settings may differ. If your device is not in our list, please try to locate a similar setting as mentioned for one of the brands above and apply it to fix the issue with faulty tracking or crashes of the LocaToWeb application.
Some manufactures allow apps to be locked (prevented from being shut down)
Start a track, then tap the "square" android button at the bottom of your phone that shows all running apps. Tap the lock icon on the LocaToWeb app (if present) in order to lock it. This should tell the phone that LocaToWeb is allowed to run.
