So I noticed a few problems.... sometimes and on the phone fiddling with something or using whatsapp... I would reply to the messages...then a while later I would get notification of that message I had already seen and replied to.. happens on whatsapp and Google Voice text messaging. for my imessages.. I would get the notification.. open messages and not see it there... I have to wait a bit before it appears.. like wtf... anyone experiencing the same?
