It's horrible. No matter what phone I've used, it buffers. When you manage to get in after entering your password two times, it allows you to use it once before locking you out, unless you exceed two tries, then you're locked out anyway. Then you have to wait 24 hours before it will let you back in. Other times it doesn't recognize your password at all and locks you out. I'm done with it. I disabled it. End of problems.
