It doesn't do it all the time, just periodically but when it does do it, it lasts for a while. Never got the phone wet, never had any other issues. It just started. Even when I hit the back button, it goes back one space and then types 3-5 more random letters or numbers. How can I fix it? It is soooo annoying and takes forever to get through even a 4 word text!
This happened to me too after I changed the screen since it was broken. But I'm assuming they just put the screen not exactly hot it supposed to be, because sometimes when I was pressing one letter the one next to it would appear and stuff like that.
