I just switched to the Galaxy S4 from an iPhone. I'm still figuring it out but am happy so far. The only issue I'm having right now is with email syncing. I only want the email app to check my email accounts when I tell it to and have set all syncing options that I can find to manual. The phone still notifies me each time I have an email. This seems like it is going out every so often and checking my accounts, wasting battery and data. Any suggestions on how to fix this?
