In the last few weeks my Samsung Galaxy SIIX has been disconnecting during calls. I hear one beep then the call is gone. It is not the same sound as when you hit the End button. I'm making sure my face is away from the phone so I don't think it's my cheek hitting any buttons. And, it's happening when I have a strong signal (4 bars). I've pulled my SIM and restarted my phone and it still seems to be happening. I've had this phone for about a year and a half and it's only recently started doing this. Any ideas what it may be? Is my phone dying??
