When streaming line features in Field Maps, the screen is required to be on. Our business users often find that they need both hands free when navigating uneven terrain, such as following a line feature through snowpack or dense forest.
The ability to lock the screen to prevent input when line streaming would prevent our users from losing data due to accidental touches from branches, raindrops and clothing. Avenza Maps has developed this feature, and users of that app within our business report that the feature is a boost to productivity. Furthermore, it would allow them to store the device in a pocket or back while streaming - an important safety improvement when working over rough ground.
