Bests & Worsts Reviews from Amazon

My son had not had his iPhone 7 for even 3 months when he started experiencing problems. His phone is well protected with a screen protector and in a case and was not dropped in water. However, the Home button and keyboard keys stopped functioning. Since he was unable to even unlock his phone the Apple technician I spoke with online stated a full restore would be needed. After the restore was complete, an error message appeared stating "The Home Button May Need Service". I was hopeful I would at least be able to setup his phone and update from the Cloud. But unfortunately, was unable to get beyond the message. So now I must go to the Apple store in hopes that they will be able to somehow resolve this issue. I have purchased 2 certified refurbished iPhones in the past, and this is the first time I have any issue or any kind. But this has been such an incredibly frustrating experience, I can't imagine purchasing another certified refurbished phone.
