Android App on Phone Keeps Closing? Missing Settings Mavic 2?

I didn’t have my P4P with me so I used my Mavic 2 Zoom for a job for the first time.

The DroneDeploy app my my LG V30 running Android 9.0 seems to randomly close after a few minutes. I checked that DD was excluded from any power saving options. This doesn’t happen on my Android Tablet running Andriod 8. Pretty frustrating.

I resumed the mission in flight and wasn’t sure if photos were still being taken with the app closed!? It looks like the shutter trigger programming is part of the uploaded mission to the drone and it keeps taking photos with the app closed. Not 100% positive but initial peep at the photo locations seems to indicate that. Am I right?

Please review this topic. It is the most relevant.

Maybe this one is more appropriate to the situation?

Feel free to comment on either option.
