Perhaps someone has some cure for this very annoying problem. This is with an iphone 4s running IOS 7.2.
My whatsapp keeps continuously refreshing the screen each few seconds. This means that if it is a longish message you often have to try a few times to read it. Also if you have more than one message you cannot read them all because the screen keeps refreshing. Apparently not all users of whatsapp have that problem!
Does anyone have a cure for this most annoying problem?
