First, think 100 times whether it is worth saving!
Galaxy Watch 4, GPS stopped working! After talking with support, they offered to send them a watch for a test. Since the warranty period has not yet expired. After 1 month of testing, the store admitted that the watch was defective and could not be repaired and offered me a replacement, to send the same watch.
I agreed. The watch was sent, BUT in an open box and used. There are signs of wearing on the strap and scratches inside the strap holder. I wrote to support and attached a photo. The store is no longer in contact! Terrible service! I do not recommend ordering!
