Motorola and Samsung native camera apps cause issue with Field Maps. Issues like app crashing or freezing. Downloading Open Camera will solve the issue. Android has removed the ability to set a default camera application. In Field Maps if there was an option in Profile under general for 'Camera' similar to the current option for 'Directions' for navigation it would solve the issue.
I have attempted to change the default on a Google Pixel, Samsung Tab S3 and Motorola Stylus 5G.
