Welcome to Android Central! Are your Google Contacts and your Blackberry contacts separate? Or are you saying that all of your Blackberry contacts are also in your Google Contacts?
Is your Lenovo phone logged into your Google account? Go to Settings>Accounts--do you see Google listed? Tap it--is the Gmail address correct? Tap that, and make sure Contacts is checked on.
Or do you need to know how to export your Blackberry contacts, and then import them into your Google account?
