Samsung Galaxy Watch 4: Where is the NFC antenna?

Thu, 06 Oct 2022 23:59:36 -0700

Unlike Apple Watch, where you present the face for NFC payment, the Galaxy Watch 4 seems to require something else. Presenting the face sideways is a bit better.

Where is the antenna and how should I present the watch to ensure best chance of payment being accepted?

Thanks

Samsung Galaxy Watch 4: Brand new Galaxy Watch 4 doesn't turn on

Tue, 21 Nov 2023 10:31:35 -0700

Just arrived a brand new Galaxy Watch 4 Classic and when I tried to turn on I had the surprise that it just doesn't show any signal (vibration, sound, screen,...).

Then I tried to charge for a while it and no signal too, it got a little hot on the back after some time but just it.

What could I do to turn it on?

Samsung Galaxy Watch 4: Where is the WiFi antenna, and how does it connect to motherboard?

Wed, 11 Oct 2023 12:15:00 -0700

My GW4 (WiFi + LTE), pre owned, was working fine when I got it, but after battery replacement it will not connect to WiFi. Mobile hotspot from my s22 works, but no other networks show up or connect with "Add Network" manual connection. Diagnostic with Samsung Members app shows 2 networks available, but none show on the watch.

Samsung Galaxy Watch 4: HR sensor not working after 12m diving

Sun, 03 Sep 2023 12:55:51 -0700

After a session of diving(12m pool water) the HR sensor stopped working.

I opened the watch 4 and no water damage or indicator marked.

Where is the HR sensor located and what can I do? (I suppose in the backplate but the green light works, so maybe a part of the sensor?).

Also seems not to be parts for this available.

Factory reset done with no difference.

Thanks in advance

Samsung Galaxy Watch 4: Can I transfer the "guts" into a Pocket Watch case?

Thu, 18 Nov 2021 20:58:45 -0700

I would like to convert a Galaxy Watch 4 into a pocket watch, I currently own a Watch 4 Classic, but I think the Watch 4 without the physical bezel would work better. But before I spend money on one, I wanted to see if it would be possible? I know I would need button holes made. But other than that?

Samsung Galaxy Watch 4: Galaxy watch 4 black screen

Fri, 13 Dec 2024 19:59:02 -0700

I have a galaxy watch 4 that was working fine until one day it just went black and won't turn on. I thought the battery may have went out and so i replaced it. it brought some life back, cause now it will vibrate if I try to force a restart but that's all it will do. The watch does not indicate that it is charging, but the charging dock lights up to indicate charging. I have also got a replacement charge coil incase it went out but that didn't solve this issue either. I've checked and cleaned all the connections. any suggestions?

Samsung Galaxy Watch 4: Changing a scratched glass

Wed, 04 Jan 2023 20:20:52 -0700

I scratched the glass of my watch. The LCD is usually working, but I hate seeing the scratch. I found some "glass" replacements on Aliexpress. I was willing to change it, but I couldn't find any reference to a "glass only replacement"; every piece of info I found seems to focus on a whole screen replacement.

Two questions: is it possible to change the glass only, and would it affect its water ressitance?
