Ghost typing on an old LG Optimus phone---->> types by itself
So I have an old LG Optimus phone. Recently it has been ghost typing, the letter "p" keeps reoccurring, and it types by itself.
Sometimes, when I hit a button nothing happens. Sometimes the screen moves by itself (as if I am swiping).
1. What is going on / wrong with the phone?
2. If it is the digitizer? how hard is it to repair?
There is no screen protector.
Thanks to those that reply,
Is this a good question?
