The cursor jumps all over the place. For instance, if I place it in the middle of an email address it will automatically jump to the end of the email address. Is there some way to fix this?
For Android: This might be a touchscreen issue. Does the cursor move strangely with any other applications?
For a computer: Are you using a trackpad on a laptop or attached mouse? A possible problem could be that the mouse needs its battery to be replaced/recharged.
