but I've been having issues with my Note 3
the Default Messaging App loses my contact names (it becomes all numbers) randomly
my Contacts are still intact if I look at the Contacts App
they are okay in my IM apps such as WhatsApp as well
the only way I can resolve this is to export my contacts, delete contacts storage and then import the contacts back again.
I'm on Note 3 MJ7 Rooted
