The last option (and likely what I would choose) is to factory reset the phone. This will wipe all data and return the phone to the state it was in when purchased. Basically you would be starting from scratch as if you'd just purchased the phone from your carrier.
I don't know why someone would sell a phone without factory resetting it and removing their personal data
That's pretty scary. I hope this helps!
Now now Brian, clearing market data isn't going to resolve it
Without a factory reset, go into app drawer, settings, apps, all apps, navigate to accounts and clear data. Once you do this clear out market data as well.
Welcome to AF! Hope you enjoy your stay here.
