good morning, afternoon or evening, 

I have a problem moderators, I don't know if you could help me, my problem is that my BDM account is linked to my google account 
and I want to change it to facebook, for the reason that in my new cell phone I don't I can start a session with google, 
since it is a huawei, could you please help me, or could you give me some solution?, thank you very much in advance for reading me.
