You are certainly allowed to take it to a sprint store and try. I dont know if they will or not.

 

I also have found this issue on my phone as well . My phone as it currently sits , the power button is barely sticking out farther than the actual bezel of the phone . I usually use my finger nail now to hit the thing . If you use a rubberized case I advise cutting a hole where the power button is on the case to use the button . I will eventually bring mine in on the issue when it gets to the point it becomes unusable . I also have developed a crack near the power button . Im again going to assume this is because the power button is sinking into the phone itself . But of course Sprint has never heard of this happening before ROFL ! Yeah right just look on the forums you will find several posts in regards to your issue . Good luck hopefully they will fix it for ya

 

If Sprint offers to replace the phone, insist they give you a hardware version 0004 or else you're risking facing the same problem again, or the screen issue.

I haven't heard anything bad about 0004 yet.

 

I recall reading that some screen separation appears to be present...and light leakage is still an issue, but that the power and volume buttons felt more firm and were raised
