The power button on my daughters phone was not working very well. She would have to press it several times to shut the screen off. I thought it was just her phone. Now my power button doesn't work at all, and can't shut screen off, I have to wait until it shuts itself off. Strange it would happen to both of our phones. I take very good care of my phone, this shouldn't be happening. Anyone else have this problem? Any solution? I have the extended warranty, but I shouldn't have to pay the deducible if the phones are defective.
