My wife's fairly new Motorola Defy phone just cracked all the way across the screen after she plugged it in to the charger. Motorola says it is not covered under the one year warranty. T-Mobile is not willing to help either. We are positive this is a manufacturer defect because:
1. We were just using the phone (Remember the Milk app, which we are both figuring out how to use), and it was fine. She plugged it in to charge, came back 15 minutes later, and it was cracked all the way across!
2. This is marketed as a rugged phone. This is why we bought it. It is water and shock resistant. Yet this phone has not even the slightest scratch and the screen has completely come apart.
I did a quick
google search and it looks like we are not the only ones having this issue.
So far we called Motorola, and they said "physical damage is not covered under warranty regardless of how it was caused". So, if Motorola screws up manufacturing and puts out some defective handsets (e.g. there is a piece of debris under the glass mount because they didn't follow clean room manufacturing practices, and then the glass fails because of this) they are not going to help you.
Contrast this with my friend's experience with his Apple product. He dropped it on the floor 9 months after purchase. The screen cracked. They fixed it for him even though it was actually mistreated.
I recently cracked the screen on my Samsung phone. It also was not covered under warranty, but I was ok with this as , in this case, I did actually drop the phone a few feet. The Defy, on the other hand, just cracked for no good reason.
