I can confirm that this works too. The random shutdown and refusing to boot is related to the battery going bad. Just finished replacing it today after buying the iFixit tool kit and the battery from Amazon.
So glad it worked! Assuming that I already had the required tools and just needed to buy the battery, I saved over $80 for repair/maintenance cost that I would have to pay if I had sent my watch in for repair!
I am having the same issue, my S3 Gear won't turn on. The battery shows 100% charged on the charger, and the charger has the green light.
I've tried all the above mentioned possible solutions and none of them have worked. Out of desperation, I decided to change the battery, hoping that would fix it, but no luck. The watch is doing the same exact thing. The new battery came charged at 65%, so I waited until it was charged at 100% but the watch won't power on. I bought the watch a year and half ago and paid over $300. I sure got a bad deal with this Samsung watch.
Samsung Gear S3 Frontier.
Battery drained and switched off. Charged fully to 100% and the watch did’nt turn on. Tried different tricks witch was suggested here in previous posts. If i put it on the charging dock then the loghtning logo comes on and after that it show’s 100% charged. After i take it off the dock the screen goes black and nothing happens.
I have been using this watch exactly 1 year and 1 day.
I have the same problem. Just few days ago in won't turn on. Watch shows it's 100% on the charger but won't turn on. Samsung needs to do something about this issue. Mine is just out of warranty and now I have an expensive useless watch.
I am having a similar problem.
I have gear s3 for a year and unfortunately, the warranty just expired.
After I installed an update and the watch reached 0% and turned off, I am having difficulty turning on the watch. I tried the suggested steps to reboot the watch and unfortunately, I was unsuccessful in charging or turning on the watch.
If anybody has any suggestion, otherwise I will be throwing out the watch and probably buying the new Huawei watch
I'm having this same exact issue. My watch started having issues with the battery (charging and holding a charge) which I first assumed was maybe the charger so I bought a new OEM charger. The problems still persisted. Next I bought a new battery and still had no change in my watch's issues.
To date, I cannot turn my watch on at all. The only time anything displays on the screen is when it is on the charger and it shows the charging battery percentage. When I hold the power button (for any length of time) it still will not turn on. Same thing when I hold both buttons. Additionally it will not turn on while off the charger as many people have stated in this forum.
This seems to be an issue that is starting to plague S3 owners as their devices start to age. Considering the watch isn't exactly ancient technology, and Samsung markets themselves as a "premium" electronics company, this is really disappointing.
Hoping to hear a fix for this issue sooner rather than later since there's no fun in having a $300 paperweight.
