Many times when I am typing in a text, the screen suddenly jumps to the top of the chat dialogue, leaving the text I enter at the very bottom of the list. This is extremely frustrating when texting people where there are 200 texts in memory and I have to scroll all the way down the list to get back to what I'm typing. Anyone know what's wrong? Am I accidentally pushing something? I think it happens when I type quickly...
You're probably pressing something- a con of virtual keyboards.
If you're sure you aren't pressing something, a factory reset may do something for you, but be sure to back everything up first!
