Samsung Watch Active Sensor Array Replacement

Turn off the Galaxy Watch Active 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.

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

Push the tip of the opening tool into the gap to separate the back cover from the housing.

Carefully lift the back cover approximately 2 cm to access the sensor array connector near the two buttons.

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

Remove the back cover.

Use an opening pick and slide it underneath the sensor array which is slightly glued in place.

Carefully twist the opening pick to separate the sensor array from the back cover.

Remove the sensor array from the back cover.
