I recently sold a Note 5 that I had been using through eBay and I did a factory reset before selling the phone. The factory reset worked and the phone displayed the "set up" screen like it did when I first got it. I was just contacted by the buyer saying the phone won't allow him to finish the setup because it was previously used with another gmail account. Is there anyway I can remotely remove that phone from my account so that the buyer can use it? I've sold many phones and have never experienced this issue it must be a new thing.
