My first move would be a factory reset. I won't guess if you set it up so what make, model phone and who set it up?
Today's news is about AT&T employees installing malware and more. Is this some "unlocked" phone that was from them?
I recently bought this android mobile phone which is released this year. But it's full of spams. I could not even turn on the data, its automatically navigates to various sites which I do not visit once. I don't know if it is some kind of virus. notifications alerts are continuously coming and fill the mobile phone. anyone know how to stop this.
