Ever since the 4.4 2 update, I get the "Unfortunate Exchange Services Has Stopped" popup error any time I use apps such as Yahoo Mail, Facebook, or when I factory reset/log in to my Google account. Basically any app that involves logging in and synching of messages I think. Then, as soon as I uninstall one of those apps, the same popup message appears. Strangely, it never affected the apps that I know of. I would still receive notofactions for everything. I've tried clearing data, cache, factory resets, nothing fixes it. Like I said, it doesn't seem to affect anything at all, and it only happens at initial log-in and uninstalling of apps, but I'm just curious if anybody else has had this happen, and if you know of a way to fix it.
