Hello i just got my andrios s4 a couple days ago and i can not get text from people using imessage, i called AT&T and they didnt help at all. My friend told me to download go SMS pro so i did and now it works with that. My biggest problem is i'll be asleep and won't answer text and half way through the night my camera flash will start going off and once i check the text or notification it stops. it doesnt flash when i get calls or text but just hours after i don't answer something. i went to the accessibility > hearing> flash notifications and its off but it still flashes if i dont answer. what can i do?
