I just got a Stratos with latest international stock firmware 2.3.2.8. Unfortunately the floors counted is just 1-4 a day which should be at least 12-15. My floor height is exactly 10 feet or 3 meters as mentioned in the manual. My former Garmin Vivoactive 3 did count it correct. Is it a firmware issue of release 2.3.2.8 or is the barometer on my Stratos broken or is the watch in general not able to count the floors correctly? How is your experience?
The altitude during bicycle trips looks OK. But it looks more as derived from GPS instead of a smooth curve as I would expect from a barometer/altimeter.
I can confirm, counting climbed floors is very poor. Highest count was 6.
Normaly (with garmin devices) I get around 15-24 floors.
Thanks for the answer. However I want to make sure if it is a general problem or just some devices have a faulty barometer. Is there an app displaying the barometric pressure?
Same here, floors climbed not showing correctly. I read at reddit a plausible reason for it: It seems like the readings have some lag. That means, if you climb a floor and stay there for awhile it will be counted. Climbing up and down quickly won't be counted. That's what it seems the reason and what I experienced, too.
You can read the barometric pressure by opening the compass app and click on it once to get to the GPS data. There you will see the pressure on the right bottom corner. My barometric pressure freeze once. I had to factory reset to get it working again. But if your cycling readings seem OK and not stuck at a certain height you likely have a working barometer.
Edit: I'm on PACEficator with WOS 2.6.1.0.
Thanks you! I checked the compass widget and the barometer seems to work correctly, it shows the correct pressure for my area. Also when I walk up a floor the pressure changes by 0.3 hPa. This is correct as well. So it seems to be a calculation problem. I think the used floor height is more than 10 feet / 3 meters. In China buildings usually have higher ceilings because of the heat. I also have that my altitude diagrams look more like block diagrams. The altitude in GPX tracks is only updated quite rarely. Hence the altitude jumps up and down but overall is correct. Just not a smooth curve like it should be and is at Garmin.
Today we had falling barometric pressure because of bad weather coming. Floors counted were almost correct. This proves that the floor height is not as mentioned the 10 feet/ 3 meters but higher. Hopefully it will fixed soon.

I'm finding the 2D accuracy is usually pretty close, but the altitude is all over the place. It's currently reading -4m despite my being a good 8-10m above sea level (including being on the second floor). The other day at the same position, it started at 22m and gradually went down to -2m even though I hadn't moved.
Anyone else seeing this?
well...i don't have that particular problem...but i do get live search aquiring the gps location somewhere COMPLETELY away from where i'm at..almost 6-10 miles away to be exact. I usually do a soft reset and all is good again....google maps usually gets my location on point at all times...jus not as expansive in options like live search
Vertical Accuracy
Vertical accuracy of a gps is never near as good as horizontal accuracy. Its more a function of the way gps works than any inadequacy of your equipment. You should get within about 5 metres horizontally when you lock on 4 or more satellites. But vertical accuracy is rarely better than 20 metres.
For more information about why this is true check out http://weather.gladstonefamily.net/gps_elevation.html
Yes, that is pretty typical of any GPS. I believe it is improved if you have WAAS enabled, but we don't have that.
the GPS program that I have [VitoNavigation] gives an accuracy in ft. on my mogul. Normally it reads above 35 ft accurate. have not tested it yet to see if it really is that far off or if the program is not right...too cold outside
@D accuracy ?

@d fix is just that. If you did not mean 3D fix then not surprised, as 2D is not the Z axis and you need a 3D fix, and it still will not be as accurate in the Z axis but should be better with a 3D than a 2D.
Umm... what?
Soundy,
That last post was a bit over my head too. (no offense intended madman, just that we didn't understand the jargon)
All i know is that the vertical accuracy you are experiencing is, unfortunately, about as good as it gets. Did you check out the link I posted before. It explains that the geo-spacial orientation of the satellites is the problem. To get a horizontal fix of your location, the gps receiver needs to see at least three satellites at different angles from your location and work out by triangulation where you are. Obviously if all three are located close to each other, the triangulation is less accurate and liable to slight - but amplified - inaccuracies in the angles that help your gps calculate your location. If the three satellites are right on the horizon relative to your gps location, at 120 degrees away from each other then you will get maximum accuracy because the angles are big and the slight error in reading these angles is proportionally much smaller.
To get a vertical location fix, the satellites that you lock onto in order to get an accurate fix need to be located at equidistant angular locations relative to your location not just in a horizontal plane like when getting a horizontal fix, but vertically as well. The only way to get the satellites in this orientation relative to your location is to have one of the satellites directly overhead and another three located in a tetrahedron format below the far horizon. Unfortunately the satellite signal cannot penetrate through the earth to get to you, so you have to rely on satellites which are above the horizon. Unfortunately these ones are therefore not located as far away (optimal) from the one directly above and so the calculation of the vertical elevation data suffers.
The same effect occurs on your horizontal accuracy when you have a fix on three or four satellites but they are all in the same part of the sky. Your accuracy, even horizontally will be more inaccurate too. Thats why its better to get 7 or 8 satellites in your sights. Its not just that 7 or 8 give more data than just 3 but mainly because they are more likely to be spaced out around the sky more optimally.
As the satellites move throughout the day, the almost random orientation of the satellites as the follow their own paths means that accuracy will go up and down as the pattern of satellites gets "better" or "worse" relative to your location.
Hope this helps

It does, thanks. I'm typically seeing 6-8 satellites, horizontal (2D) accuracy is usually pretty good... at worst it seems to be 6-10 feet off to the west (ie. it shows my position a little further west than it actually is). It's stranger to me that the altitude seems to "wander" so much - like I say, the one time it started at +22m and slowly went down to -2m... while I was sitting still
I'm an avid hiker/trail runner and former Blackberry owner. My old 9930 was unable to accurately (or even rough ballpark) determine altitude by utilizing its GPS sensors. But the Note has a built in barometer which measures air pressure. This should allow fairly accurate altitude readings especially when combined with GPS. Are there any programs available that utilize both the barometer and GPS to calculate altitude?

If you install Elixer2 from the market you should be able to test the sensors to ensure they're accurate in the first place, then I'd do the hunt for apps to use it. Last thing I'd wanna do is pay money for an app only to find out the barometer is broken to all hell.
Search the market... I'm sure you will find something.
Hi, i'm interested in playing with the Barometer data in this thing too.
If you don't find any decent apps for it, perhaps i'll add it to my to-do
Just installed Elixer2 and checked the pressure sensor relative to a home weather station I have and it's dead on accurate to what I'm getting from the weather station.
To quote someone more famous than me: "You're all clear kid, now let's blow this thing and go home!" to which I mean start hunting on the market.

I've been searching. All the "altimeter" programs out there utilize only the cellphone's GPS sensors to determine (i.e. guess) altitude. The results are, at best, horribly inaccurate. None of the programs utilize a phone's barometer... which makes sense as there aren't many phones out there that have them integrated.
There are a few in the market. Just search barometric pressure, most state only for galaxy nexus and Xoom...as those where some of the first with the sensor but should work on the Note
Edit top four are free apps also

This one uses the barometric pressure sensor, it's very simple though.

u can run sensor test there
Raw data from the built-in barometer will not be all that accurate for determining your altitude. All that you will get is the barometric pressure at your location and, possibly your uncorrected altitude relative to mean sea level. In order to obtain your correct altitude, the app will have to access the AWOS data from the nearest airport, to get the correct altimeter setting. High or low pressure systems moving through your area can cause your altitude to be incorrectly calculated by a couple hundred feet or so. This is why aircraft altimeters have an adjustment on them to dial in the current altimeter setting.
Hi, I know that the smart watch is Ip67 protected. Up to 30 minutes maximum depth of one meter. Is it possible to swim with him in the pool without diving to depth at all and a maximum of 20-25 minutes? (swimming during breaks).
Also, which app has the swimming area that works with this watch?
Thanks.
I would say no, watches for swimming are usually rated at least 5 ATM, this is 50 meters. The problem with these ratings is that they rate pressure, and the pressure is measured when the object is motionless. When you start moving the object, the pressure increases. This is what you feel when swimming.
Check here for the classifications. Note that a 5 ATM watch doesn't even pass for snorkeling.
Personally, I wouldn't risk it.
It can withstand hand wash, rain etc.
I don't go with it into the shower

You can swim with it - no problem. I use my for swimming from the start - actually I only take it off when charging.
1 year already -> no problem.
p.s. Do not try in see - due to the salt it could be damaged somehow. I would not try. But pools - no problem at all.
Then you are lucky, because IP67 is called water resistance, not waterproof.
http://www.trustedreviews.com/opinion/what-is-ip68-ip-ratings-explained-2947135
The second you move the watch under water, the pressure will exceed the 1.5 meter mark and the risk of a breach is quite high.
We have a lot of people here that had that happen.
Mine , after 5 months of no problem shower with it , now has less than half a day duration after swimming in a pool.
Swam with them in the pool for the test, I got them for free. As a result, they did not survive. Then I decided for myself to look for a watch that I can not take off my hands and they will not be afraid of moisture and damage.
I found this option here Casio Pro Trek PRW2500T. They passed my rigorous tests and falls and long voyages, except boiling Everything is fine with them, so they have some confidence, but I only use them for 3 months, so time will tell.
I have an Amazfit Bip S and am frustrated with the Pool Tracking accuracy. Recently i swam 2000 yards in a 25 yard pool and the watch recorded a distance of of 2700 yards. Is anyone else having accuracy issues. I also tried using open water tracking and the accuracy was worse. The GPS tracking had me swimming in circles on a straight line swim.
Did u get any better result?
They now use the ZEPP apps instead of the mifit app.
I notice swimming with the bip S seems to be very week.
no data interms of Lap time, Stroke per lap (in pool swimming)
also open water is a mess with GPS all over the place.
I have just got this watch for my swimming. So far I am very pleased with it but I am having an issue with the lap counting. Firstly I hope this is not too out there but it seems when I wear it on the left wrist I get extra laps counted, it seems to tick over laps in the middle of laps...after 4 pulls. I have tried it on my right wrist once and it worked perfectly. My theory is I damaged my left arm many years ago and have somewhat limited rotation and my stroke on the left is not as high as my right. This round arm stroke seems to trigger the watch as a lap. I know the answer maybe to wear it on the right but I have always worn my watches on the left (60+ years).
It seems the sensor(s) might be a bit sensitive and I wonder if anyone else has had a problem. Another thing is I have a mi Band 6 and it was very accurate on my left arm.
I would be pleased to hear from other stratos 2 swimmers if they have accuracy problems in the lap counts...maybe there is another setting I have not found yet. (I do set it to the the correct wrist).
As I said the watch has all I need as far as usability goes I just need to get the accuracy....Thanks.

A quick update....I have done several more swims with the watch on my right wrist and it performs perfectly....looks like my action is the culprit. This post may be of some help if you are having accuracy problems....
