Just got a used E90 and I really enjoy it. It is far better than my old 9300. However, I found the hinges of the phone are very loose. What I mean is that when I open the screen, it still locks into the two positions, but if I hold the phone, the screen is wobbling a lot (quite amount of free play). To me, the hinges need to be tightened. Can you tell me if this is normal (especially if you get your phone new)? I am thinking about sending out the phone for repair, but would like to get your opinion first. Thanks a lot!
