so I have an old iphone 4 and now im currently using galaxy s3
i still use my iphone as like an itouch and yesterday i upgraded my iphone and this thing popped up and i pressed ok or whatever even before i could read it.
After that whenever someone with iphone tries to text me, it would go to my brother's iphone! (because my brother and i share same apple ID)
so i told my brother to check off my number from the send&receive menu
and now he doesn't get it anymore but it started to come to my iphone.
So i turned off my iMessage… But I still don't get the text on my galaxy s3.
What can I do to fix this problem/?
