I have a stock Galaxy S4 running 4.2.2 and about a week ago the phone ran out of battery and when I plugged it in and turn it on all my e-mail accounts were gone and I had to re-install them, any idea what happened?
Also, since then my exchange account stops syncing and when I go to the settings for the account the Sync E-mail is unchecked and all the sync settings for calendar, contacts and tasks are unchecked as well. This has happened several times since then.
Today all of my exchange contacts were gone and I could not get the phone to sync them. I tried to uncheck the sync settings and then re-check it to no avail. I had to remove the account and re-install it to get the contacts and calendar synced.
Any ideas as to what is causing this issues?
