bought the GPS watch: runner just one year before, started since last month, after used the stopwatch model during swimming, I stopped it and put it back to clock model. But, about a couple minutes later, it automatically went into the stopwatch model again, and I couldn't stop it ,and had nothing to do with the watch. I had to wait the battery completely gone, then after recharged it, it could be back to normal.
This issue happen many times recently. Don't know if it's still under warranty. Couldn't find the support contact info once it first time happened.
Just would like to ask that anyone has the same issue, how can I get it fix?
