The back of my Galaxy watch 4 appears to have several scratches. Although I don't know how they would get there I've never dropped it and when I don't wear it it's on my dresser. It also has some charging issues. I have place it on the charging pad 3 or 4 times before it starts. And it won't charge by wireless power share

Samsung does not stand behind their products. I had an issue where the entire back piece came off my watch and subsequently came in contact with moisture. It's a waterproof watch less than a year old and they voided my warranty and wanted me to pay over $200 to repair it. These watches have design flaws and they know it but will not warranty them. It's made me seriously start looking at other phone and electronic brands all together.
