How can I change my Samsung account e-mail address?

[OAYAR]

I am using Samsung Galaxy S5. I do not remember my Samsung account password. The mail address I registered to Samsung was a hotmail. I cancelled this email. I am no longer using this email. I am using gmail now. I also, changed my phone number. From settings---accounts---samsung account I see my old hotmail address. How can I set my gmail for my Samsung Account. (Sorry for bad English)

If you can't remember your password, you can't yet. See if you can create a hotmail account with the same name you used to use. Then use "Forgot your password?" to have it sent to your hotmail account. (In the future, use a password safe, so you'll only have to remember one password, no matter how many you use.) (Asking Samsung for help probably won't get you any - they're not very "customer-friendly".)

And your English is fine.
