Have you ever tried to text someone or type an email while your phone is connected to a wall charger? The most annoying thing happens when I do it. If I press a letter and doesn't matter which one, I will get a whole slew of letters filling my screen. Sometimes its the same letter or a combination of several different letters. I now have to disconnect the charger when i want to type because its annoying. This, I might add has to do with the ON SCREEN keyboard and not the slide up. I do not notice this issue when the phone is connected to my car charger though.
