I have had my watch for 4 months and the back panel came off yesterday. Like everyone else who has posted, mine has not been exposed to water. Is it actually worth following up with Samsung on this? We have had major issues with the company when purchasing appliances for our kitchen and their customer service is absolutely appalling considering how much of a loyal customer we have been over the years. Can the watch operate without the back panel?
I would contact Samsung and see what they can do if the watch is still under warranty , I'm sorry you're experiencing this , I suggest not to use it without the back before further damage occurs.
Sorry to hear that this happened to you I would recommend contacting one of Samsung Certified Repair Center at the links below to help get it fixed.
Had my Samsung galaxy 42mm watch since Sept 2018 , the sensor cover on the back has been repair twice and the battery for over heating, a week ago the sensor cover fell off for the third time, sent my watch in for repair and of course they claimed water damage , if they could make a sensor cover that would stay intact for what they claim is a water resistant watch they refused to repair their defective design, so a watch that I paid over 300$ only lasted a year and half and that was with 2 repairs for the same defective part , loved the watch and functions very poor quality and very poor customer service . If you can't be active and sweat when wearing a 300$ watch then it shouldn't have sport functions VERY POOR QUALITY and even worse customer service SAVE your money and buy something that won't fall apart when you use it for it's intended purpose !
Can you please provide me with the ticket number for your repair in a private message: http://bit.ly/2JH2rq2
Seems to be really common. I cant believe that they didnt take care of this the first couple of times.
