    • Turn off the Galaxy Watch Active2 by pushing and holding the bottom button for approximately 3 seconds. You should feel a short vibration.

    • When the "Power off" symbol appears, tap the center of the screen to make it shut down. You should feel a longer vibration for confirmation.

    • Use a Tri-point Y00 screwdriver to remove the four 4 mm-long screws on the back of the watch.

    Y1.5 works just as good

    The screws are attached to the cover. So you just need to loose them, not remove them.

    Any tips for a too tight screw ?

    • Use an opening pick and place it between the plastic back cover and the metal housing near the buttons.

    • Push the opening pick into the gap to separate the back cover from the housing.

    • Don’t remove the back cover all the way yet. There is a cable connecting it to the motherboard.

    There is a glue-ish gasket keeping it closed. I used an exacto knife to start it opening.

    This was super helpful thank you! Perfect timing

    • Carefully lift the back cover to access the sensor array connector.

    • Use a spudger to disconnect the sensor array from the motherboard.

    • Remove the back cover.

    Where would you recommend buying a new back panel/charger?

    • Use a spudger to disconnect the display assembly and the speaker.

    • Use a spudger to disconnect the barometric sensor, the buttons, and the microphone.

    • Place a spudger underneath the motherboard at the top right next to the display connector.

    • Slightly twist and lever the spudger to loosen the core assembly.

    • It might help to also check the comments below this and the next step if you’re having difficulties.

    I would not suggest to do so. There are components underneath the motherboard as well. There are none in this specific corner, but the core assembly does not come out that easily and people might try other corners and positions. Rather unscrew the motherboard and remove the battery from the core assembly directly.

    Nicola Tambascia -

    Yes! I was unable to remove the motherboard as pictured unless the screw was removed (Step 12). I suggest a re-ordering of steps in this guide.

    • Grab the core assembly and carefully slide it out from under the cables.

    • Remove the core assembly.

    I had to remove that screw on the core assembly using a Phillips 000. When I initially tried lifting, the core assembly started to bend. Mine also has a connector under the core assembly near the thumb in the picture. The connector goes from the underside of the core assembly to the screen/body. It prevents me from removing the core assembly as I'm not sure how it should be removed examining it

    Louis Finney -

    This step is really difficult, and I'm still not sure it was necessary. The core assembly is really packed in there, and it took me several attempts, lifting from various corners. Don't pull by the circuit board. It will bend if you're not careful. You've got to get under the core assembly. I had the most luck starting next to the display connector at the top, then moving to the sensor on the other end of the board (barometric sensor), then moving to the speakers on the left, and finally lifting from multiple points once it was out far enough. In really hoping I didn't damage anything.

    Karl Arp -

    I think the comments here should be added to the step before.

    Nicola Tambascia -

    I would be very careful following Louis Finney's advice above. They are describing detaching the motherboard from the core assembly which also includes the battery and internal frame. Removing the motherboard from the rest of the core assembly exposes a very delicate looking ribbon cable that I nearly tore by trying to remove the screw holding the motherboard in place.

    As Karl Arp notes, trying to pry the core assembly up by the motherboard feels like it puts a lot of strain on the circuit board, so it might be necessary to go at it from multiple angles.


    Removing the whole core assembly was very difficult, and required a lot more force than I was expecting, and I had the luxury of being able to approach it from both sides, as the screen had already detached from the device (hence the need to repair), and still found it very challenging.

    I would advise, at a minimum applying mild heat to the metal outer frame to hopefully cause it to expand and give some additional clearance.

Conclusion

To reassemble your device, follow these instructions in reverse order.
