I don't use the exact case you have. I use the full body case verizon sells and when taken off do not notice anything clicking.

 

Have not noticed this but I don't take off the top part very much. I have found that I can fit mine in the car dock by only removing the lower part so the top part usually stays on. FWIW, I still have the silly plastic piece on the back of the screen. YMMV.

 

I replaced a phone already that had a very loose screen. I also had the case you are referring to and thought that it had something to do with it. As I look at the replacement phone it does seem like the space on the left side is smaller than needed to fit the tabs on the case. It must push the two halves apart some. Not sure if this caused it or just the act of taking the case off several times pulled it apart. Either way the second phone is perfect and solid and I will not use that case again.

 

I have the shell/holster combo. Bought it yesterday (Sunday). Just got the phone on Friday.

With the case on, no clicking.

Just tried taking the top part off, and it clicks a little on the left side. Mostly on the upper left, and maybe a little on the bottom left.

NOT sure if it was this way before I put the case on though. Again, just got the phone on Friday.

Not sure it bothers me though. If I started using the phone without the case, maybe it would? But again, not sure if it was that way prior to the case.

I figure over time, the phones will probably get loose though.

My only concern/hope is that the keyboard doesn't get so loose that it won't stay closed. Have you heard of anyone having that issue?

 

I haven't noticed anything yet. I originally had the clear plastic snap on hard cover but I have OCD when it comes to new electronics and when I would slide my phone it would scratch the the front right of the phone(under the mic) and along the back right of the slider along the screws. I just bought the shell/holster combo and i love it! Haven't noticed any gap yet (knock on wood), and the slide does seem tighter(with the clear plastic removed off of the slider). Will keep you guys updated.
