[AC Question]

I have an LG G2 that is a little over 2 years old. Certain keys on the keyboard won't register when I try to type them. instead of typing a 'c' I get an 'x' a 'v' or both of them. same thing happens with 'f'.instead of that, I get a 'd' or 'g' or both of them. And whenever I type a 't' it always gives me 'te' it is making texting and everything else on the phone involving typing very difficult. Is this a keyboard issue or a screen issue?
