iphone 6 plus screen flashing white and black

Hopefully you have an Apple store near by. Did you do a google search for this problem to see if anyone else is experiencing this issue?

Have you tried a Reset by holding down the Sleep / Wake Button and the Home Button at the same time until the white Apple logo appears, then let go of the buttons, but wait until the Reset completes and you are back at your lock-screen? If this doesn't work then do you have a computer with the current version of iTunes? If yes and you already have a Backup of your Media and Data on iCloud or iTunes, then you can put the iPhone in DFU Mode. Don't do this unless you have a Backup and also have a computer with the latest iTunes. You will need your Apple ID and Password. To go to DFU Mode you can hold the Home button while you plug the Lightning Cable into the iPhone, a graphic will appear on the iPhone screen showing that you need to connect to iTunes. At that point just connect the iPhone via the Lightning Cable with USB into your Computer. Open the iTunes App on the Computer and wait until a button appears representing the connected iPhone. Then click on the iPhone button on the iTunes screen and it should open to the Summary page. At that point you can Restore the iPhone to Factory Settings and bring it up as A New Phone. The iPhone should screen should then show Hello and you will need to connect to your WiFi via your Router WiFi Password and then answer all the question put forth by the iPhone. When the "Lets Get Started" occurs you can thoroughly check out the iPhone to make sure it is all OK. When satisfied that things are good, you can plug into the computer and iTunes and this time Restore from Backup. or if you Backup is in iCloud you can Restore over the air.

I have this same problem -- does anyone have a solution?
