Please help. My vivo account can't be opened and I try to register with a mobile number always failing. Please help me. 

Password: vivo1105I am using the public account.
Password doesn't work all of a sudden so can't log out.
This vivovivo123 clearly doesn't work and why you posted it beyond me.
How do remove the account without wiping the phone. So I can add my own ?
You seem to be in the same boat as me. Were you able to find a work around for your device? Which phone do you have? I am getting the Nex 3.I already have a Vivo account created with my united states region email. But I can't install vivo account 5.0apk cause my phone already has a newer version installed and won't let me unistalk it not unistalk the updates at all. So when I try to install the Vivo account apk from the link it says instalation failed. Also after login into vivo account on the computer I don't have a way to bind a phone because there's no USA region to choose from. Anyone has this issue?
