Chosen Solution
My Samsung Gear S3 Frontier watch is dead, when put on charger red light normally lit, after about 1.5 minute it start flashing, i tried to remove it and re-put it many many time but no success any advise or description of what it might be the cause. Thanks for help..
Jeff i found the solution for this case but it is hard, it worked for me perfect as i’m an electronics engineer the solution is to open the back cover of the watch and solder 4 wires usb cable inside and connect it to any USB charger it will open in seconds again if you are not qualified for this, look for someone can do it for you since then i never let my watch die again look at this video this picture
