Really want but don't feel like tearing down my phone that far. I had that inside casing out on the weekend, it was a big enough pain in the ass (although probably the hardest part) and would only allow me to get at the buttons, didn't have the bezel off.
I did that because there was a gap at the bottom when cover was on, turned out that interior plastic was not sitting on the the proper support inside at the bottom, it was mushed down onto the part of that brace that sticks up more. I have had a minor drop since I got the phone back from repair but given the nature of the damage I think it must have happened when the repair centre put the phone back together. Reshaped that bit of plastic and all is right again.
