Introduction

Replacing the screen of the Garmin Vívoactive 4 (M/N: 03618) is an involved process and requires a few tools.

There are many reasons why you may require to replace your screen. For example, it may be damaged, it may not be functioning, or perhaps it is not performing as expected. Your screen also may not power on in the case dirt or dust is reducing your devices responsiveness to touch. (see Screen Wont Respond in the Vívoactive 4 Troubleshooting Guide).

Please note:

  • Handle your device and tools with care as to ensure you do not hurt yourself or damage the watch.
  • This repair requires the use of a heat gun. For information on using a heat gun safely, take a look at How to Use a Heat Gun to Soften Adhesive guide.

    • Wedge your fingernail or the tip of a spudger underneath the watch band's small metal pin.

    • Push on the pin to release the strap from it's hinge.

    • Pull the strap away from the watch to disconnect it.

    • The strap will not pull away if the pin isn't fully pushed in.

    • Use a heatgun to loosen the adhesive beneath the screen, it should take a 5-10 minutes for adhesive to loosen.

    • Handle the watch with care to avoid burning yourself after it has been heated. Review the How to Use a Heat Gun to Soften Adhesive guide.

    5-10 minutes is too long and too short at the same time. I didn't even heat it for 5 minutes on low and the watch was already too hot to touch. I put on some gloves and tried to wedge my jimmy in between the screen and the case but the seam is much too thin, even when I broke out my knife for it. I thought the glue must not be loose enough yet, so I heated it for a couple more minutes and tried again. Even though I did completely discharge my battery before doing any of this, my battery started to bulge and the back of my watch deformed. I followed these instructions as closely as possible, along with the "how to use a heat gun to soften adhesive" guide, and I never got my screen off and now my watch is beyond reasonable repair. If you decide to try this, I hope you have better luck, but I don't know how you're supposed to be able to get this done.

    • Wedge a thin opening tool or your iFixit Jimmy in between the seam where the screen and the watch’s housing connect.

    • Pry the screen off the device.

    • There is a cable underneath the screen that needs to be disconnected - be careful not to rip it.

    • Work quickly so the adhesive doesn’t cool too much.

Will this affect the waterproofing of the device?
