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

    • Use a Tri-point Y00 driver to unfasten the four screws on the back of the watch.

    • Don’t worry about removing the screws, they will stay in place in the back cover.

    I heeded your advice - and now need another screw because it fell out!!!

    I must have stripped the screws out or either the dirt and sweat is so packed into the screw i can't get a good bite to unscrew the screws. What can I do about this? This watch battery DOES NOT hold a charge for more than 5min, should I trash the watch?

    • Insert an opening tool between the back cover and the metal housing.

    • Twist the opening tool to create a wider gap.

    • Don't fully remove the back cover just yet. The sensor flex cable is still connected to the motherboard.

where can I get the galaxy watch3 rubber gasket?

regards

Miguel Vera - Contestar

That’s a good question. As for the previous models it is very hard to find those rubber gaskets. Using a “liquid rubber gasket” might be one solution to that. (Use carefully to not spill too much on and into the watch)

Tobias Isakeit -

I tried to remove all of the screws from the back cover, but 3 of the 4 screws remained and seemed to be fused to the main base of the watch. One of the screws was stripped. Now only 1 screw is engaged with the back cover. (I might need to replace the back cover. My watch is glitching which is draining the battery. I would like to fix the problems myself. Where can I get specific advice?
