Samsung Gear S3: stuck in a reboot loop help!

Mon, 22 Jun 2026 21:35:48 -0700

Gear S3 was disconnected from S7 Galaxy this morning. I tried reconnecting from the app in the phone, and it didn't see the watch. I tried to reset the watch from the boot menu. Now it wont reboot, and I can only turn the power off through the boot menu. I've seen several people complaining about this issue, but no solutions. Any advice or help would be appreciated.

Samsung Gear S3: Won't Turn on After Replacing Battery

Sat, 12 Apr 2025 20:06:45 -0700

I replace the battery on my Gear S3 Classic. I followed some video and had no issues. I've dealt with this kind of stuff before.

The charging screen comes on when I place it on the charger and it seems to react when I push the back button. I mention this because it doesn't do anything at all when I hold down the "Home" / power button.

I've researched a good amount and saw that some people have success with holding both buttons, holding the Home for 10 seconds, and of course checking all of the connectors. I have also tried using the original battery.

Of course, I've had no luck with any of these. My current guess is that the home button is not working anymore for some reason.

Has anyone had this issue and if so how did you fix it?

If not that, could someone link me a resource to learn more about the insides of the watch so I can continue troubleshooting it?

Thank you!

Samsung Gear S3: Anyone having trouble removing the tri-point screws?

Mon, 23 Sep 2024 06:33:36 -0700

I have the Pro Tech Toolkit and have tried using all the tri-points included (Y000, Y00 and Y0), but none seem to be grabbing the screw properly. The tear-down indicate that the Y00 should do the trick, but it seems like the tip is too pointy and is floating above the grooves. Anyone have the same issues or have any tips?

The back glass screen is chipped. Is it possible to replace it? I had to put a piece of tape on top of it because I was afraid that water could get inside. All the sensors work, and the watch is functioning 100%. Can it be replaced?

I'm trying to change out the back of my watch because the glass is cracked, but I have a feeling I may might have at least partially stripped the screws even though I have the right driver… How easy is it to strip them, and how would I go about removing them if they are?

Samsung Gear S3: HR sensor not working

Mon, 13 Sep 2021 13:49:02 -0700

As per title, HR sensor not working at all, tried soft/hard reset, re-pair doesn't help as well.

Wake-up gesture not working too, the watch seems to be not able to detect my wrist without HR sensor, no matter how hard i swing my arm the watch just won't turn on itself. Sleep monitor stopped working too (probably due to HR sensor not functioning)

what could be the cause? device was connected to samsung note 8, thanks in advance.

Samsung Gear S3: Menu button is not working and sometimes, display doesn't come up.

Wed, 24 Feb 2021 11:19:55 -0700

Menu button is not working anymore, after a year or so. I have to press back and menu buttons together for the menu to come up.

Also, display doesn’t come. You can hear the notifications and screen is only displayed when a new notification comes up. Else, it stays black.

Samsung Gear S3: Won't recognize mobile network

Tue, 27 Oct 2020 00:33:47 -0700

I recently sent my gear S3 frontier in to Samsung for repair. It was overheating and not fully charging. Amazingly they covered all the costs even though the device is clearly out of warranty. Thought awesome right? I get my watch back which was originally from Verizon and I'm currently using T-mobile & now it suddenly won't register the network. The watch locks up displaying a phone number to contact Verizon. I did and they said they could not even locate the device in their system anymore. Supposedly after 6 months they release network holds on devices and it's been like 3+years. What can be done???? Please help??

Tried restarting, rebooting, reset and just about everything I could think of??
