I'm having some issues with my 7 month old Galaxy S3. For the past month or so, every so often my messages (sms) folder in the home page will go empty when I click on it. Or, I will be typing an sms and when I press send the entire message history will be gone and then the phone will freeze and when I restart all my messages will appear back in the folder. This is a concern because I am not sure if my messages are going through when that happens or if I'm receiving messages. Also today all morning I received no text messages or calls and then all of a sudden at noon I get flooded with several text messages and voicemails and seeing the time on those messages means I was not receiving them when they were sent to me. And I didn't receive a single missed call but then I had 3 voicemails from various times in the morning. Not sure why this is happening! Some help would be really apprecaited!
