On this episode of Repair Radio, we tell our scariest repair stories in celebration of Halloween, and iFixit teardown engineer Taylor Dixon makes another appearance to talk about our Surface Laptop 3 and Pixel 4 XL teardowns.
John K. on Twitter asks: “Is contact cleaning a thing still? Recommendations?”
It is a thing! Dirty contacts aren’t as much of a problem in newer phones, but in general, making sure not to get finger oils on contact surfaces is a good idea. If you need to use a contact cleaner, a bit of isopropyl alcohol goes a long way.
“PH000” asks in an email: “What is the chip under the display in the iPhone 11 Pro that you showed in the live teardown?"
That is a Samsung display power management integrated circuit. We’ve updated our teardown with that information!
