So I picked my phone up off of my desk at work today to check on something, and I noticed a small but very noticable crack in the screen! I have NO idea where this could have come from because I've NEVER dropped this phone, I keep it in my pocket by itself (separate from my keys) and when it's not in my pocket it's either on my desk at work, resting on my leg in the car, or on the couch or nightstand at home. I've never heard of a screen just randomly cracking by itself but there's no way that I did this! Has anyone ever heard of anything like this? Do you think Nokia will repair/replace this under the warranty? The phone is only 3 weeks old!
