Chapter One (UI):

1. [Optional] Email verification lacks validation on things like @ and dot (.)

Chapter Two (Code):

1. [Optional] mEmailLength inside companion object rather than an instant variable.

[Optional] It could be an if statement. when used in place of nested if-else

when (it.status) { Status.FAILED -> enableContinueButton() }

3. Instant Karma (Or as they say karma is a ...) :| p0, p2 and ....

override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {}

4. mSetEmailResponseLivadata spelling is wrong
