Insert the edge of a spudger into the the loudspeaker opening at the bottom edge of your watch.

When prying up the back cover put a finger on top or the edge of it and hold it down. Too much force during the prying procedure may lead to popping off the back cover too quickly and tearing the rear panel assembly cable.

The plastic clamps holding the back cover in place sit very tight and may require some force during the prying procedure.

Use a spudger to pry up the rear panel of your Huawei watch GT 3.

Don't try to remove the back cover assembly all the way yet, it's still connected to the daughterboard.
