Bests & Worsts Reviews from Amazon

Phone looked great out of the box, but was unusable due to the Factory Reset Protection being activated. Spent a frustrating 3 hours researching, then dealing with Google and Amazon Customer service. There is nothing that can be done - without the previous owners login info, a new acct can not be added. I am frustrated that a "Certified renewed" phone would have this problem. Amazon Customer service is sending a replacement, let's hope this one doesn't have the same problem. I purchased this item with reservations, as I have had problems previously with "certified" devices. Will not make a big ticket certified renewed purchase again.
