Why do all of my text messages keep disappearing? Still! The other person still have the chats but because they're in my favorites every once in awhile they keep getting deleted out. I backup my chats every single night. So why do they disappear? This issue needs fixed now! Messages have even started to disappear from the night before! This is ridiculous! Fix it! Just counted. I lost 6,000 messages overnight after I had it backed up.
