When mapping a new polygon feature in Collector, as soon as the screen times out on it's own, or is "locked", the streaming/mapping stops. When the phone is unlocked again, Collector simply connects the last known location to the current location with a straight line. However, the interim is a more complicated geometry than a straight line. The phone needs to be in a locked mode because it is placed into a pocket so that the field user can safely traverse rough terrain. Sometimes mapping a feature can take close to 2 hours. The user needs to be able stream the location in the background for the whole duration.
This is using a Motorola Z Force with the most current updates. Other Motorola phones, Samsung phones, and i Phones don't have this issue. Other users in the same organization do not have this issue either, so it doesn't appear to be a web map/content issue. We have checked the phone settings and the setting allows Collector to be used in the background.
Are there other permissions that we are not aware of that need to be changed on the phone? I have searched Geonet, forums, etc, and haven't found any mention of this issue, besides for Windows phones. Also, if this should be posted elsewhere, my apologies.
