I have noticed some of the copper pipes behind walls are not tied down with straps. If I take a shower arm or a sink angle valve and push in it will yield 1/2" to an inch.
I assume this is probably they used an elbow instead of a drop ear 90 for the shower connection, and for the sink, who knows, may be just didn't tie it down.
Is there a solution for these kinds of problems - without opening the walls? Any sort of a clip you can tighten onto the drywall and has a hole you can put through a copper pipe? I doubt it but thought I would ask.

Back when I was running all copper I'd place a 2 x 4 block between the studs ,drill two holes in it, 4" o.c. and stub the copper out of that. 1/2" of play was considered normal and not a problem. If you strap the copper down tight , I suspect the hot line will tick as it heats and expands.
The shower arm should be screwed into a brass dropped earred ell that is securely fastened. Mobile home supply stores sell a shower arm that has provisions for securing to the sheetrock. I'm not recommending one, just saying that there are ways to deal with a loose arm.

if it is loose and you are getting water hammer noise, it is a problem. or unless there is a threaded connection you are trying to unscrew, it is not a problem.

I wouldnt worry about it unless their is a problem because of it. Especially the angle valves, that play may come in handy in the future. I did recently come across that problem when installing a gooseneck extension shower arm. I ended up packing the arm with steel epoxy putty behind the plate, where the arm comes through the plaster and tile. It secured it very well. It may not be so easy if you have a fiberglass enclosure.
