Okay so I disabled iMessage on my iPhone before my M8 was even active, its been over a week now and I have turned off iMessage on literally all of my apple products and for some reason I still can't receive some texts from certain iPhone users. One day it'll work fine and then the next day I don't receive them. This is also happening with some group messages too. My brother who is an iPhone user could group text with my friends and I fine the other day, and all of a sudden today I can't receive any of his messages anymore. I've already spoke with Apple and had them manually deregister my phone # from iMessage and apparently that doesn't seem to be working fully either. Does anyone else have this same problem or something similar and if so how did you go about fixing it? Incredibly annoying. Never had this issue on my AT&T branded M7 with or without the AT&T stock ROM.
