I have been having several issues with my X. Rebooting, touch screen freezing, and voice activation only working part of the time. Called tech support who told me to go to my local store (where I purchased it) for an exchange. Only problem is all my local stores are out and won't order a new one without taking my phone or charging me 300.00 as security that I'll replace it. Customer service told me the same thing. Is this standard or am I just being taken for a ride. Don't have 300.00 for a replacement and can't be without my phone.
