We recently moved into a mobile home and one of the doors would keep opening.
I adjusted the box and strike plate (just moved them all the way over, shifted it over to the right to be closer to the outside of the door) which solved the problem for a while:
But then it started coming open again and I saw the box shifted left again.
So I moved it back and re-tightened the screw, this time using a power tool, but it came loose again.
The door opens outwards (to the right in the picture) and I wonder if the box/strike-plate are mounted upside down... I can't take them out through the hole though.
Do I have to take the door frame out to flip the box/strike-plate upside down? I just want it to stop shifting left so the door closes properly and stays closed.
I tried flipping the strike without removing the door frame as @harper-reinstate-monica suggested. It's pretty tight in there, the right side doesn't drop into the door frame.
Here is a picture of the door frame as @crip659 suggested:
