Samsung Galaxy S20 USB-C Charging Port and Daughterboard Replacement DIY Tutorial

Duration: 45 minutes
Steps: 25 Steps

Ready to give your Samsung Galaxy S20 a little TLC? In this guide, we’ll walk you through replacing the USB-C charging port and daughterboard. Since the USB-C port is soldered right onto the daughterboard, you’ll need to swap out the whole board. Just a heads-up: how well you seal everything back up will determine your device’s water resistance, so make sure to reapply that adhesive like a pro! Keep in mind, though, your device will lose its IP (Ingress Protection) rating post-repair. If you need help, you can always schedule a repair.
