Q: Home Button Won't wake up Phone, and Touch ID doesnt work.....

So I purchased a used iPhone 6 plus from an individual.  I was assured that the phone was in perfect working condition.  After inspecting the phone in person, it was exactly as described.  Wasn't iCloud locked or anything.

I finally got around to getting it up and running last night and putting my backup of my 5s on it.  I noticed when I first was setting up the 6 plus from scratch that it failed the touch ID portion of setup.  I didn't think much of it since my touch ID hadn't worked on my 5s for so long.

So...... After getting my update on the 6 plus I noticed that when the phone was "asleep" that if you hit the home button nothing would happen.  You can hit it as many times as you like and absolutely nothing will happen.  So I then hit the power/sleep button on the side and it wakes up.  I put in my 4 digit passcode and the phone unlocks and everything seems to work normally.  Put it to sleep, and immediately try the home button to wake it up and it wakes up.  You can go back and forth with it as many times as you want like that and it will work.  Let the phone sit asleep for longer than 5 seconds and the home button once again becomes unresponsive to waking the phone.

I had also tried after getting the phone restored from my backup, trying to set up touch id.  When you go into it and try sliding it on, it immediately goes to a failed screen.  Please go back and try again. 

So frustrating!!!!!  I tried doing a reboot by holding the power and home button down until it reboots, and that didn't help anything.

Can someone please please please point me in the right direction of this.  Very frustrated!!

Thanks,

Kyle
