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

      • 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

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)

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?

@isakrittl Du schreibst: "Achte darauf, dass die Gummidichtung (rot markiert) in Ordnung ist. Falls sie beschädigt ist, ersetze sie beim Zusammenbau durch eine neue, damit die Uhr wasserdicht bleibt."
Wo bekomme ich denn eine neue her? Hab nirgends eine gefunden... Danke!
