Over the last two days my Galaxy S3 has been having increasing trouble loading emails and now it's completely stopped. I'm using the email program that came with the device and it's set to pull up emails directly from the server. I've tried rebooting. I tried deleting a secure text app that I thought might be causing compatibility problems. No difference. I hit "load", it tries to connect for a few minutes, then nothing. My carrier, btw, is Virgin Mobile (they use the Sprint network). Please help.
