Question Trouble with heart measurement- Galaxy Watch 4 Classic BT - Samsung Galaxy Watch 4

Is anyone having difficulty getting ECG or other heart related measurements to work reliably? I seldom am able to get readings. I do have metal watch band, FWIW.

for ecg, make sure the watch bottom touches your wrist completely. get those magnet bands. will help

What's a magnet band?

Pedometer and Heart Rate Sensor

Anyone having an issue with the HR sensor not picking up a pulse? I've tried both sides of the wrist and finger tips. Keeps giving me a message "unable to measure heart rate. Tap again to measure") Maybe I'm missing something. Also, the Pedometer is not measuring ANY steps. I feel like I've gone through all the settings. Figured I would try here before contacting customer service. (They really are not knowledgeable on their hardware in my opinion.) Any help is appreciated, thanks.

The only thing I could think of is you have it on too tight or not tight enough. I still have the protective plastic on mine and have no problems with it still detecting my heart rate.

Hy. So you mean that the Gear S3 can have the heart rate during during a run by feets. Because i am thinking selling my polar clock and replace it by the gear S3.

Trick the watch into thinking its being worn?

I got the new Samsung Gear Sport and apparently it doesn't realize I'm wearing it due to the bone in my wrist or the tattoo I have. Is there any app that I can side-load or find in the gear store that will trick it into thinking its being worn?
That's... Odd. There's a chance that your watch is defective, it might be good to see if you can exchange it or have it sent out for warranty if you try it on your other wrist and it still doesn't work. What if you move it a little higher up? Is there any situation you've been able to get it to think it's being worn?
Lastly, what symptoms is your watch experiencing that makes you think it doesn't realize it's worn? I can use my watch when holding it in my hand.
It works on the other wrist just fine, it works just fine further up the arm....it's the tattoo. The only thing that is bothering me is no always on display because it thinks I'm not wearing it. It won't read my blood pressure which I could care less about.
My Zen watch 2 would still show always on display when it wasn't on my wrist... Why don't companies actually quality control test stuff properly anymore? =(
So, I found an article about someone getting theirs to work with a reflective material. Bent washer + $5 chrome skull sticker, and electrical tape = win.
Watch always thinks it is being worn. Doesn't read heart rate but don't need that.

My LG Watch Urbane 2 band mod

Well, since I had no intention of using the cellular function on my watch, I decided to attempt installing a normal watch band and I think that it all turned out nicely. Noting that this watch will accept a 22mm standard watch band, I first checked to see if a standard 22mm spring pin would fit and it did so nicely as far as the length goes. The holes that the screws fit through are much larger than the standard pin normally fits it so to keep the pin in place within the band you have two choices. Either use a standard pin and glue it into the band so it cannot slide in either direction or use a band that uses the quick release pins like I did. I used one of the "Milanese" magnetic bands that a quick release pin would fit into. It was one that I had already and I like the adjustability of it and it is black in color which matches the watch well. Now as far as the open slots where the original band's antenna connectors is concerned, I covered them with some tiny pieces of self adhesive thin craft foam that I got at a local Walmart in the crafts department. Two small rectangular pieces cut to fit worked very well to seal off the openings and it look like it was made to be there. It was a little tricky to install the band but it seems to fit very well and is very secure as well. Here is a link to just one of many of these bands offered on eBay. I would attach a picture of my LGWU2 with this band on and worn on my arm but I do not see a way to do that here.
** UPDATE... Well I just discovered that the antennas in the original band are not for the cellular service only. I was losing my Bluetooth connection only a few feet away from my mobile phone. WiFi seemed to work pretty much the same though. I thought this would be a good idea, but I guess not. Oh well.

Thanks for sharing, I had been thinking along the same lines as you and it seems you are 90% there, I have a few questions (and suggestions) that only you can answer
First - as far as I am aware the watch primarily uses wifi to connect to the phone, not sure if it is WIFI Direct or some sort of sharing through a shared router were both device need to be connected - not sure on this, if it is a direct connection to the watch then BT doesn't matter much.
Lets suppose you need BT to work.
So you plugged up the holes on each side of the watch which is fine and maintains its water resistance but and this is a big BUT, did you think of stripping the Connectors and antenna out of the original band and using them to plug the into the watch, you could then extend the antenna under your new band (out of site) and attach using glue or something, that way you plug the holes in the watch as intended with original connectors and also retain some of the connectivity, only you can answer this as I don't know exactly what room you have to play with, the old bands are useless anyway so maybe you could carefully strip out the bits needed to achieve this, you may only need to do it on the side that supports BT antenna
Just throwing ideas
forgot to ask
do you have a link to the bands you bought

Thanks for the suggestions on extending the antennas but in my case, my original band is in perfect condition so I am not willing to deconstruct it yet. Th thought of using parts from an old unusable band did cross my mind and I even put out some posts asking if anyone had a broken band that they wanted to give away or sell but I have not gotten any responses on that yet. The Bluetooth and WiFi both still worked but the range from my phone was about six feet at the most. I was nice to have a smaller and lighter band for a day but it just did not work out as far as getting notifications and weather updates while walking around the house. The link you asked about is https://www.tntkstore.com/lg-band-parts. I ordered a set of new screws for my band from them. They are in China but the delivery time was not bad at less than two weeks. They sell the most parts for this watch that I have found anywhere. The fact that LG has nor offers these bands and parts is an abomination in my opinion but I love the watch anyway.
I am very careful with my watchband and do not flex the ends any at all if I can help it. I have large wrists so I only connect to the second hole but when I am putting it on or taking it off, I try to pull it as straight and gently as I can. I plan on ordering an extra band to put back as an extra. I have gotten used to the bulkiness of the band now and I don't mind it at all anymore. I wish that there were other options for more flexible bands in different styles and colors though. I have attached a picture of what my watch looked like with a Milanese style magnetic band on it. I used small pieces of adhesive craft foam sheet to cover and seal the antenna connection ports. I hope I have helped in some way with this. Have a good day.
I can live with 6 feet lol or I might just buy a spare band, I am like you and will be careful, I think if I get 3 years out of the new watch I bought I'll be doing ok and might look for what's new at that time, TBH I would have bought the Samsung S3 Frontier if it had been AW - by far the best watch out there at the moment but we shall see when the time comes
Thanks for the link
I just upgraded from a Sony SW 2 which I had for years lol and also from an Xperia Z1 to a XZ2 Premium so new stuff all round and loving it
cheers my friend
check other thread
even though I was careful my band is failing and am in the process of fitting a 22mm stainless steel band, I only use and need BT so only one antenna will need to be retained (the BT antenna probably supports the wifi too)
check out the other thread I updated with photos

Has anyone replaced the Band with a standard 22mm

I have been trying to establish if it is only the LTE that stops working or WiFi BT NFC and GPS, can anyone confirm this please, or if someone is willing to detach the standard band and see what is affected, I have read conflicting info on the net but cannot find anything conclusive
I removed mine last night, because it's broken. I'm waiting to receive another original, but I can test something if you want
Where did you order a new band?
First off, I have tried to replace the band with a standard 22mm watch band and was successful in doing so. However, the antennas in the band are used for not only the cellular signals but also the wifi and the bluetooth as well. The watch will function as a timepiece without these connections but you will not receive any notifications or updates to any functions connected to your mobile device unless you are withing a few feet of it. I found the watch to be severely crippled in that respect so I reinstalled the original band.
As for any replacement parts you may need, you can find them in only one place and that is this website...
https://www.tntkstore.com/lg-band-parts
I have ordered from them and they appear to be a very reliable source for replacement bands and other parts. I received my order in approximately two weeks as well.
I hope this information is useful.

I still believe it is possible to strip back the old band and basically allow it to remain as part of the watch (antennas intact) and still leave room to fit a standard 22mm band of your choice, this will also leave the watch water tight
Have you had the band off of your watch yet? The opening for the connectors is quite large and the original band is designed to close and seal this opening around the contacts. I too thought of making such a modification to my watch. My current band is in great shape and I was not willing to sacrifice it just yet so I have not gotten that far. The band I did try is an all metal "MIlanese" style band which I though might also act as a passive antenna but it did not work out. I sealed the openings with small pieces of foam tape which looked like it might work to a certain extent but certainly would not offer anywhere near the original IP rating of water resistance. I personally do not think that there is any viable way to use any other band than the original style. I really wish that it had worked out as the metal band was much more comfortable. I have however gotten used to the stock band. Good luck in your endeavor I hope you find a better way to accomplish this. I have attached a picture of my band replacement. Like I said, I wish it had worked out.

I have worked in electronics all my life, I repair my own phones and sometimes will also do same for friends so I am familiar with this sort of stuff.
I cannot say if my solution will work because my watch is relatively new and in good shape, but I will certainly have a go once the time comes.
My solution would involve stripping the old band back just so it leaves enough room to mount a new one, it could involve tucking part of the old band under the new one which would leave a little more attached, it is a thick watch so I don't see this as a problem as it sits fairly high off the wrist, at this point I am just using a little imagination as to how this would work but I don't see why not with a little careful trimming.
If someone was willing to supply me with a defective watch to try this out rather than dumping it I'd be willing to spend a little time on it and report back here with my findings.
I do hope that you are successful. I too have been a tech most of my life and fabrication and modding is also a hobby and profession as well. Sometime back here in this forum I posted a search request looking for a broken band either to be given or purchased but I have not ever gotten any offers in either case. I was going to try to leave just enough of the original rubber part to use as a seal and then encase the antenna portion in maybe shrink tubing or whatever seemed appropriate to insulate and isolate it from any direct skin contact then bond it with maybe a flexible silicone adhesive to the new band. If ever I get my hands on one I still plan to give it a try. And if I ever do, I will post my creation here for you or anyone else interested. I hope you will do the same with your work. Again, I wish you success with your endeavors.

sounds just about right and is exactly my thoughts too, I don't see why this would not work, it would all be hidden under the new band
The wireless could possibly end up slightly weaker but I don't see that as a problem and if the IP rating is maintained then we're all good, you might have to use an adhesive/sealant for the remaining parts of the old band to make sure it stays in place but hey, so what
Have you seen that one
https://www.ebay.com/itm/LG-Urbane-...l-Smartwatch-W200A-Smart-Watch-2/123509118860
That is one awesome looking band with an awesome price tag! I am not sure about how it works with the Bluetooth and WiFi signals since it is metal. The description says that the NFC function is disabled because of the metal band so it stands to reason that all other functions would be crippled as well. There are no pictures of the inside of the band and the only picture of and end does show one connector but I can't see the connector on the other side.
I did a search on the band ( Tag Heuer Link metal band ) and the band by itself is $600. I could see how that someone could modify this band to work but it just would not be practical. This ebay listing to me sounds suspicious. I could be wrong but still, I could not see spending that much for it. I do however think that it looks gorgeous with the LGWU2 watch. Thanks for posting that link. That was a great find.

that is what I would be doing if I needed to replace the band, what this proves is the concept is 100% possible, very expensive - I can buy a whole new watch for less than that
If you zoom the first picture you can see one of the antenna between the links running down the back of the strap
https://www.ebay.co.uk/itm/22mm-Sol...=item25fc2908b5:g:Hi4AAOSwTxpZqNgb:rk:10:pf:0
question, do the screws that attach the strap screw into the watch body and extend into the strap or is the strap itself threaded
well it has come the time for replacement, mine is splitting and coming off the pin (one of the mounting pins has come away)
I have sourced the metal band shown in the above dead link and is on its way to me - not cheap at $85 but I believe will be a much better lasting solution for this great watch
I have concluded that I only need the Bluetooth antenna fitted as generally I don't need the wifi - sat - or NFC so I will only have to improvise with one side of the band.
I have also concluded that the band does not contribute to water resistance and this is in fact part of the antenna connector inside the side of the watch but I will also use a silicone sealer to back it up.
I haven't identified which antenna support BT and if anyone already knows this please share
as shown in the included pictures - I have sourced screw type pins to mount the new steel band to the watch as the spring type will not work.
I haven't decided how to cover the antenna on the back of the new steel band but will update once I have it all completed, so here is what I am aiming for below and also the band and mounting screw pins I plan the use
Great job! You must have some great craftsman skills. It looks like a band that was made for that watch. I still have my LGWU V2 but I have not worn it in a while. I am wearing a Huawei Watch Gen 1 now. Thanks for sharing the pictures. :good:
update for those interested
the antenna use a little rubber plug to attach to the side of the watch which is part of the antenna when removed and retains water resistance, see pics
I have tested the BT reception without the antenna (without metal band) and works quite well, I suspect this will change when I attach the metal band so I will need at least one antenna, I believe the short antenna (with 2x connectors) serves the BT and WIFI and the other one (with 1x connector) is for GPS and Cell network which I don't use, I may just fit them both
I plan to use the stripped and split part of the old rubber band on the back of the metal band and glue over the antenna - it will be secure and out of sight - don't see any problems with this, this new metal band should outlive the watch - only thing I have also bought is a replacement battery for when I will need it going forward (batteries do wear out)
All in all I see this as a great way of prolonging the life of a great watch for at least a few years - the metal band will always be ready to use on a new one - I might even buy an LG Urbane 2nd ED as a spare if I can get at the right price - or even one with a broken band if anyone has PM me
here are the pics of how the antenna attach to the watch
What band is that? Where did you get it? I'm thinking about replacing the band in my watch and really like that one.

it is very expensive and requires a little work to make it fit 100% $80
https://www.ebay.co.uk/itm/153102879816?ul_noapp=true
My band broke so I thought I would share what I did.
I replaced it with a 22mm silicone band with quick release pins. I'm still trying to figure out how to cover the ports for the antennas, but at least they don't stand out as much as I thought. I have been wearing it for a couple of days and the band has no problems staying in place.
I first tested Bluetooth and Wifi with a metal band and didn't have any issues. Wifi seemed a little slow but I'm not sure if the band had anything to do as it was slow in other devices as well, and I haven't tested wifi with the silicone band.
I don't have an active SIM in the watch anymore so I can't test LTE, but it seems to connect with the inactive SIM it has right now.
just tape them up - like with PVC tape
the route I took is costing, trying to get that band to fit is more than I needed - but getting there with some heavy duty filing and getting the right pins to screw the whole thing home
I have done some extensive testing and unless you are going to be operating your watch far away from the phone - everything works pretty much ok for BT and WIFI
I have bought a 3100 based watch so I now have 3x smartwatches the LG being the oldest - so it is a sort of hobby now what I am doing
my advise now to anyone replacing the band is to go very cheap silicon and buy a couple of screw type bars to mount it

Fixing a Gear S3 - Bezel Rotation sensor not working

All - My S3 got wet and went into a bootloop. I sent it to Samsung and they sent it back without fixing it claiming that it was too expensive to fix. It is up to me to fix it myself.
I managed to resolve the bootloop problem by opening it up and letting it air out. (see other thread for details)
Question - the only problem I have now is that when I rotate the bezel, it doesn't register anything on the watch. The connector/ sensor seems to be dead.
Anyone know how I could fix this? Do I need a new entire display unit (Samsung Gear S3 frontier (SM-R760) Display unit complete grey GH97-19658A) or is there something else I should try? A part to replace?
I did take off the bezel and I cleaned it. (did it very carefully as there are pieces that can be easily lost)
The watch works well and I can do almost everything without the bezel working but would like to get it working to 100%.
Thanks for any ideas people may have.
Same problem
same problem on my Galaxy Watch. Any update on how to fix?

I took mine apart again hoping I could get the bezel to work but no luck.
I assume the sensor connects to the top part of the watch. There are two connecters that attach to the main part of the watch, a big one and a much smaller one. Perhaps the smaller connector is the problem.
Not a super big deal but I would love to get my watch working at 100%.
Any Samsung techs with an idea?
I figured out that my problem was just that I was wearing a watch band with a magnetic clasp. If the magnet was too close to the watch, but bezel wouldn't work. If I switched bands everything was fine.

You sneaky son of a gun. That worked.
For what it's worth: the bezel sensor is a set of 3 hall effect sensors. If you take the bezel ring off the watch (various youtube guides show how) and look at the underside, you'll see 24 indents and 8 of these (1 in 3) will be a different color. If your watch isn't registering anything, these magnetic spots may be de-magnetized.
https://www.ifixit.com/Teardown/Samsung+Galaxy+Watch+Teardown/117519 <-- explained here (see step 15 ... and if you look closely at the bottom right of step 8 first picture you can see the 3 hall effect sensors in place)
On my watch it sometimes didn't register the bezel turning. I thought it might just be gummed up. I eventually noticed that it would miss 3 "clicks" in every rotation.
Now I finally understand why: one (only one of eight magnets) has become de-magnetized and the hall effect sensor won't read it as it passes across.
Now I just need to work out how to re-magnetize the one spot.
