I did a full reset on my phone earlier this morning to resolve issues with being unable to reinstall a few apps (Amazon Appstore & a podcast player). It went through the setup process and seemed fine, having me set up Google, email accounts, etc. While trying to change the live wallpaper, the device rebooted.
The phone currently will not let me drag down the bar to access normal phone features. It seems like the touch screen is non-responsive. However, I can call the phone from a land line and it allows me to drag down the bar to answer the call as well as use the End Call button. Afterwards, I can do nothing on the phone. If I use the power button, it turns the screen off and it will not come back on save for another call or removing and replacing the battery.
