How to Open the Samsung Galaxy Watch4 Classic

Difficulty

Moderate

Steps

Time Required

5 - 10 minutes

Introduction

Use this guide to remove the back cover of the Samsung Galaxy Watch4 Classic.

Tools

Step 1

Before starting repairs, take your watch off the charger and power it down.
Remove the watch band.

Step 2

Use a Tri-point Y00 screwdriver to remove the four 4.0 mm-long screws securing the back cover.

The y000 screw driver is not right. Tip is too long and doesn't engage screw correctly causing them to strip

I found I needed to use a Y00 screw for this.

Confirmed the Y00 is what you need for this step.

Step 3

Insert an opening tool into the seam between the back cover and the metal housing.
Twist the opening tool to create a gap.
Don't try to remove the back cover all the way yet. The sensor flex cable is still connected to the motherboard.

I suggest to work the plastic pry tool between one of the pairs of spurs that hold the wrist bands on. It worked much more easily for me than working at either side of the watch. ~Rufus T. Montgomery

Step 4

Lay the watch face down.
Carefully swing open the back cover by folding it to the opposite site of the created gap.
Use the flat end of a spudger to pry up and disconnect the sensor flex cable from the motherboard.

Step 5

Remove the back cover.
Make sure the rubber gasket is undamaged. If damaged, replace it with a new one during reassembly to maintain proper water resistance.

Conclusion

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