I have had my HTC Rezound for right at a year. I have replaced the SIM card twice, had the phone replaced once (in September 2012) and now it's spazing again. I now have issues where the screen will come up as a split duplicate screen, or it will go all fuzzy like it can't figure out what it should be displaying. When you press the power button to turn off the screen and press it again to bring it back up it clears it. Also, the volume button will no longer change the ringer volume, it will only change the media volume. I shut it off to reboot it and I get the message that this phone needs a SIM card to work (which it has) and then it goes away and finishes the boot process. I have not downloaded any new apps in over a month. My phone is in an Otterbox case and I'm careful with it....can someone please tell me if you are having the same problems and if I can fix it??
