      • I've performed this on a few Fitbits where the adhesive was worn out enough that with a light amount of prying the touch screen assembly lifts right up

      • A hairdryer on high should work you may have to use it for longer

      • Heat the glass screen with heat gun to soften the adhesives

      • Insert a razor blade between the glass and the body

      • Keep going around the rim of the display until loose

      • Reconnect battery connector

      • if the battery wasn't dead before repair it should turn on now

      • Put the battery back in place

      • When I was replacing the screen I also replaced the battery that's why the battery changed.

      • 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

      • And voila you now have a repaired Fitbit Charge 3
