    • Heat the glass screen with a blowdryer to soften the adhesives

    • Start the next step on the opposite side of the Fitbit wording below the glass. This is due to the display cables being located there

    • Insert a razor blade between the glass and the body

    • Keep going around the rim of the display until loose

    • Flip down the screen and remove any extra glue that squeezes out

    • Take a rubber band and wrap it around the device, this will ensure the display stays in place until the glue cures

    • With the rubber bands on go to step 1 and reverse the steps to reinstall the band release

    • The glue will take between 24 and 72 hours to fully cure

    • When the glue is fully cured remove the rubber bands

    • After all is done you will need to calibrate the battery to do this charge it to 100% then leave it charging for an extra 2 hours use the device until it dies of low power and finally charge it to 100% and it should be good to go

    • And walla you now have a repaired Fitbit Charge 3
