A bright green stripe has appeared on my phone screen, from top to bottom. Or bottom to top, depending on which way you swipe.

This phone is five years old and I'm expecting possible battery issues, but not a display problem. I wonder if Samsung added a snippet of code to start a screen falling apart after five years. They want to sell me a new phone!

Is there an agency that monitors Android code for these big players? I'll bet not. Companies like Samsung and Apple have proprietory code bases that could contain anything.

Code can operate the electronics down to a binary level. What if code was included to go online after five years, and start extracting random phone issues from a company database.

And them implement these issues in a random manner. Self destruction of a solidly built computer, to get you to buy a new one, in a way that is untraceable. They don't want your phone to last!
