Not so great finishes. What can i do?

[Darshan Patel]

So we have a property that is finishing up, with outlets/switches, and fixtures.  I came in today and saw some of the outlets with weird gabs (pic below).  I think the drywall cutout was too big, is there anything i can do by myself or something an electrician should be able to adjust or fix?  We do plan to have a painter come back to do touch ups.  

Not sure about his one, how it came to be.  What do you guys suggest to fix this gap?  Something i can do?

Im sorry about pics being sideways, still figuring out why it does that.
