Please, please help me. My birthdate apparently is incorrect on Facebook. I can not log in.
Also if I get a verifying code by e-mail I can not go back to the page where it is requested because I am working from a Samsung Tab and it does not see.
I would try to create an app password from Facebook. This will let you log into your device using a generated password from your account instead of your actual Facebook password. See Facebook's instructions on how to do so.
