My phone just went bezerk. It was working just fine. I started getting bad signal...then I couldn't call at all...then when I tried to call I got "emergency call only" message display and now my phone won't even power on all the way. I push the button to turn it on and it lights up but just stays stuck at the beginning screen. My daughter has the same exact phone so I tried switching batteries...no luck....my battery works in her phone just fine but her battery in mine still does the same power problem...getting stuck and doing nothing else. Anyone have an idea why this is doing that? I'm confused....
