This is a question directed to those who had a wood back and returned it due to problems with the back "delaminating" / pulling off. I noticed on one corner of my phone that the wood back is starting to come loose. This is very minor at this time. I know I have some comments from some other folks on this board that some may have returned the phone due to this. My question is if you did return it, how bad was it? Do you have any pictures? What did you replace it with? Many thanks...
