I've tried restarting the phone. I've tried rebooting by turning it off and then back on. I've removed the battery. No matter what, I get this message, regardless of how I go about trying to change the settings. Does anyone know what's happened and/or how to fix this problem?
I've got a Verizon Galaxy S4, all stock, not rooted or anything. It's been working fine up until today. I'm not getting any email notification tones. When I go to the settings for the email app, the stock app, click on Account Settings and select the email account I want to make changes to, it says "Unfortunately, Email has stopped.".
