So I'll be in the middle of a text, and randomly when I'm typing on the keyboard, it vibrates for every letter I press, and if I press a certain letter it will go to something else, like for example, if I press e it will go to email, if I press c it goes to calender.. and idk how to make it stop unless i turn my phone on and off.. which has become extremely annoying. PLEASE HELP ME!
