HTC One M8 - Disable AT&T address book
I recently reset all data on an HTC One M8 and now the AT&T address book has shown up. I have tried disabling the related application and cleared all cache, but the thing still shows up under my list of address books under contacts. Even another reset of all of the phone data didn't remove it!
The worst part part is that there is no way I can find to prevent it from being the default place for adding new contacts, even with the background application entirely disabled. Obviously those contacts aren't being synced anywhere if the background service isn't even running.
I have never clicked anything to indicate I want to use the service, so it shouldn't be signed up. Any time I've seen something mentioning the service I have always clicked cancel, no, or similar.
How do do I completely get rid of it? It doesn't show up on my other Android or Apple devices, only his one.
