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 Galaxy Watch 5: Samsung Watch 5 pro Stuck in retail mode

Thu, 26 Jun 2025 07:06:14 -0700

Purchased watch but turned out to be a demo watch.

The retail mode app is there. 5444 gets you in but when you select off for the retail mode it goes to the Home Screen and does not turn off.

There is another factory reset screen in the Retail mode app but it prompts for a password when you try and reset.

Please help….

Apple Watch Series 3: Apple Watch series 3 no touch after screen replacement

Tue, 03 Dec 2024 02:43:29 -0700

I recently replaced the screen on my Apple Watch series 3 Nike + edition. The screen comes on and the buttons work but there is no reaction from the device when I touch the screen. I have tried force restarting it dozens of times and it has changed nothing. The old broken screen does not work at all so I believe that trying to use the old digitizer will not work. Anyone have any ideas?

Samsung Gear Fit2: Replacement Charging Pins Badly Needed!

Tue, 10 Mar 2020 18:22:43 -0700

I need to replace the badly corroded charging pins on my Gear Fit 2.

It was a gift for pre-ordering the Samsung Galaxy Note 7 (That I still have), and I'm pretty sure that Sammy (Samsung) will not replace, or fix the device without me first returning my Note 7 (which I have no intention of doing so).

Is there somewhere (Amazon, Newegg, E-Bay) where I can purchase a replacement?

I'm an IT professional who has no problem tearing this thing apart and rebuilding it myself, but I just need to have the correct replacement parts on hand before doing so.

If anyone can provide me a Part Number, or the correct name of the circutboard that I'm replacing; that'd be most helpful.

Thank you in advance.

Apple Watch: Will the Apple Watch sapphire digitizer work on apple watch sport?

Fri, 01 Nov 2019 21:16:54 -0700

Greetings!

I work as a repair technician and I am now looking into Apple Watch repairs.

One thing came to my mind: I'm sure people would, if they had the option, rather have their broken Apple Watch Sport Ion-X glass screens replaced with a sapphire glass instead of the Ion-X glass.

But.. Will the Apple Watch digitizer work on Apple Watch Sport?

Fitbit Sense: Can I reattach my Fitbit Sense watch screen?

Tue, 24 Jan 2023 03:24:49 -0700

I woke up yesterday and the screen on my watch had disconnected and was just dangling. See photos. The display disconnected from the case of the watch. It's still connected by the cable connectors, and the screen is still working, but I need to re-adhere the display, if possible. Can I just add some adhesive and reconnect it without having to replace any parts?

Apple Watch Series 3: Black foil on OLED display damaged

As my top glass on the Apple Watch 3 broke, I ordered a new digitizer. When I removed the glass from the display, I damaged a black foil on the OLED display at the edges. The display is still working, but there are bright areas, where the foil is missing. What kind of foil is on the display? Can I replace it? Where to buy?

The display looks like this now (glass removed, dark foil damaged):
