My first galaxy watch back came off after 2 years. Ibouught new active 2, the back came off after a month and a half. Appears to be a desing flaw as there are many cases. There website gives you an error message when you try to order repair envelope. Called them they made a case gave me a ticket number and said they sent mail in label. it never came. I have been on chat with them for over an hour, they refuse to text me a qr code, mail the label or provide the repair address. Most frusting experience ever. I willnever buy a SAmsung product again and am reporting them to Better Business bureau.
