I had to send my first iPhone 6 Plus back because the camera wouldn't focus, they sent me a refurbished one. It worked fine for a while until it would no longer take a charge. I contacted apple and they sent me another refurbished one. A week later my third 6 Plus keeps freezing and a white grey area appears from the top. This probably happens 70% of the time. Should I just keep playing the refurbishment game or do I have other options? Can I demand a new phone from Apple? Feel like I'm not getting anywhere.
