The service center said that it's easier to buy new ones - replacing the board will cost about 10,000. I do not recommend wearing them in water / taking a shower, there is always a risk that the back cover will come off. Before that, I used Xiaomi Mi Band 3 for 2 years (bought for 1300), there were no such problems and could not be. Now they have another person and still work. Initially, the expectations were that a brand like Samsung would not save at the expense of quality. Since 2022, I have been using different Korean-assembled Samsung appliances, such problems have never arisen. The watch assembled for 2022 broke after 1.5 years. Draw your own conclusions.
