Has anyone experienced any pain when wearing the watch?
I've bit got it on tight and even when wearing loose. The pain is constant. It starts with a throbbing pain in the wrist which goes up to my elbow. When not wearing the watch I have no pain. I have only had the watch for 5 days now.
In this case your best option would be to contact samsung directly as their are no service center that will physically service the watches onsite these items are usually shipped out with proof purchase or further inspection down below i have attached a link
For shipping repair, you need to call Samsung, the hotline is indicated in this link: https://www.samsung.com/us/support/contact/
i have also the same pain encountred.just bought couple of days ago and its really painfull.
my perception is that some sensors are radiating badly and most one i guess the heart rate.PLEASE SAMSUNG need to intervene, several cases now reported some of the guys did not get any feedack except you replaced the watch or returned the money.
this is SERIOUS !!!!
