What can I do about strange colors on my iPhone screen?

Episode 1336 (1:40:30)

Chris from Florida
Apple iPhone 6

Chris has an iPhone 6 and with iOS 10.1, and he's getting strange colors when he resets it. Leo says that is a symptom of "touch disease," which is from a faulty video chip used. It misbehaves and starts spewing random data that can eventually get worse. Apple hasn't acknowledged it yet, although thousands are complaining about it. Even Apple Store techs are saying it's a common feature they are finding that requires repair, and Apple is charging to repair it if the phone is out of warranty.
