简介
Use this guide to remove or replace the I/O Daughterboard in your Samsung Galaxy S8 Active. Components that would warrant replacement of the daughterboard include a damaged USB-C connector or microphone.
This guide involves removing the back cover of the device, so you will need replacement adhesive to reattach the back cover to the phone.
Before disassembling your device, be sure the battery is charged below 25%. If accidentally punctured or damaged, the battery can catch fire and/or explode; if discharged below 25%, the chances of fire/explosion is decreased.

Thanks for writing this guide! It let me fix my phone successfully :)
Here are a few tips for anyone else trying to follow this guide:
- The screw sizes (3.5mm vs 2mm) are off. All the earlier screws are 3.5mm, and all the later ones are 2mm
- It’s a bit risky, buy you may need to gently use something sharp to cut away the back cover. I very carefully used an exacto knife, only cutting in a few millimeters to get it started. Then I switched to a putty knife.
- Connect the motherboard and the IO daughterboard before inserting them back into the phone.
- The black and white antenna cables must be placed very particularly to allow the loudspeaker to fit. Route them through the small notch in the motherboard, which you must do before putting the motherboard back in.
- Make sure the loudspeaker assembly, NFC and charging coil are flush with the back cover when you insert them. This requires aligning the tabs at the edges underneath the adhesive. This is important if you want the back cover to fit properly.
