Pressure Sensor - Inaccurate Reading hPa - BM1383GLV - Huawei Watch 2

Hi,
It appears that my watch is not showing an accurate reading of atmospheric pressure.
It hovers around 860-870 hPa but the weather websites report it above 1010 hPa in my location.
Has anyone experienced a similar issue? Any fixes?
Thanks

You are right. I was at around 1350m above sea level hence the reading. Now close to sea level and the reading has gone up to above 1000 hPa.
Should have paid more attention during geography classes.

Is the screen resolution really that bad?

I'm hearing really negative reviews on the tab plus screen resolution as it's not great outside in the sun and it is unbearable. Is this true? Do you guys believe the screen resolution to be really that bad? Thanks.
The screen resolution has absolutely nothing to do with sunlight readability so I don't really understand what you mean here

Don't know if it's against the rules but one was from Cnet. Another user was talking about it as well. Don't flame me, i'm just trying to see if it's all hogwash per say because i'm really considering getting a galaxy tab plus.
the resolution is fine for my eyes. I don't quite get what all the hype about resolution is these days... My computer monitor is around 100ppi... Why do I need a tablet or phone that has 400ppi?
What about the brightness level. That's the issue I've heard some things about. People are saying that the GT+ is very dim and difficult to see outside.

I can't comment on that, really. 99% of my usage is indoors, and I might have to wait until May before there's another sunny day where I live. Then again, the only tablet-like devices I've ever seen that are actually good in the sun are e-ink devices (kindle touch, nook touch, etc)

Again, some sources for where this brightness issue is coming from would certainly shed some light (excuse the pun)?
I have to agree with garyd9 here. My tablet lives indoors most of the time. The few times I've been outdoors with it I was able to crank up the brightness to where I had no issue with seeing the screen. Typically I leave the brightness set between 20-35% indoors and occasionally to as high as 45-50% depending on the light in the room. In full dark I run it to minimum as its too bright. Maximum is insanely bright and I can't imagine many scenerios where I would need it to be that bright.
It should be noted that I don't use the auto brightness as it is wholly inadequate for the purpose. I imagine that users who are complaining of dim screens are relying on the auto brightness feature and not adjusting the brightness manually. Overall I find the tablets brightness to be more than capable of handling the job.

Thank you for your honest opinion. I guess that's what I was looking for earlier but maybe I was just misunderstood or something. But I thank all you guys for your honest opinions here.

You may also consider checking out the tablet in the store if possible. Stores are usually very well lit inside and should give you an excellent idea of the tablet's display capabilities.
For future reference so there's no confusion: your initial post contained contradictory information. You were asking about screen resolution when you really meant brightness. Which, as captnodegard pointed out, are two completely different things. It's helpful to use the correct terms when asking for advice. It's also best to cite sources when referring to other critical reviews, as some people may not have seen those reviews.
Good luck in your decision!

THIS TAB SUCKS!!!! (I'm referring to Ainol's Novo7 Tablet. haha).
Anyways, I have a lot of experience using the GT+ outdoors since i always bring it with me in my college. Most of the times i use it outdoors when the sun is in its full glory. I have a matte screen protector which is why sun reflection is not an issue. However, I have to increase the brightness to 80% just so that i can have a pleasant view on the screen. 60% brightness is usable but I love the colors when I'm using it with 80%.
I also notice that the back gets hot whenever i turn FULL brightness on. Which is why, i capped myself to only increase brightness to 80%.
However, I live in the Philippines where a 32 degrees Celsius (90 degrees Fahrenheit) is normal which could have contributed to the back heating up.
In my opinion, the screen brightness was too dim. Particularly in auto brightness. Compared to my Sony s and htc flyer, I wasn't impressed. Selling mine because of this and other disappointments.

What "other disappointments"? Just curious.
I routinely use the tab as a TV in the car during traffic on my commute and if the sun is behind me then its essentially unwatchable at 100% brightness but aside from that it works fairly well.
I don't know how well it stacks up against other 7'' offerings except the Nook Tablet which I had tried out first in my hunt for 720p playback and the two seem similar in screen brightness.
I have noticed the 7+ does not feel as bright as my 10.1 but overall it works well enough outdoors and no screen except e-ink really works well in direct sunlight anyway.
I back up that last claim with testing done on:
Galaxy S and S II
iPhone 4 and 4S
iPad 1 and 2
Galaxy Tab 10.1 and 7+
The time I tried to use my laptop outside after I said "Gee it sure is nice outside"

The inability to customise mini apps, disappointing. This is available on 7.7. Also, the peel application is unable to control several of my devices...e.g. found no support for VCR. Found Sony S much better for this. Poor position of power button allows frequent accidental activation whilst working with device. I admit latter point could be due to my own clumsiness

Galaxy S4 Sensor Array: Barometer, Humidity, Temperature...!

The Galaxy S4 has so many amazing sensors! Magnetometer, Proximity, Ambient light, Gyroscope, Accelerometer, Barometer, Thermostat, Humidistat, Infrared!
The barometer is the most exciting to me because I build pressureNET, a global network of Android phones reporting atmospheric pressure and current weather. This project is open source and we're hoping to grow large enough to get meteorlogically significant data, which should allow us to improve thunderstorm forecasting significantly. We're collaborating with atmospheric scientists at University of Washington who are currently receiving a livestream of or data. We're currently receiving about 11,000 measurements per hour. Check out our blog at cumulonimbus.ca.
What other ideas do you have? This is Star Trek right here. What else can we build with this incredible sensor array?
This thread deserve a bump.
Seems like a lot of extra stuff taking clock cycles due to polling. Any way to turn some of that stuff off if you want?

Where did you find this information? I haven't seen anything like that so far.
I also am interested in how the temperature and humidity sensors will be used. I hope developers can figure out interesting applications.
I downloaded a few barometer apps for my Note a year back but they didn't seem that useful. I will definitely try out the pressureNet app; it sounds quite interesting.
I made a Weather Station app that utilizes these sensors a while ago and is available at Google Play for free:
Weather Station
In regards to the OP, globally collecting information from these new sensors I think has minimal value. First of all the sensors are not stationary, second they reside inside of pant pockets most of time. Atmospheric pressure may have some value but it is not useful unless you adjust for elevation (which my app does).
I for one and curious how the humidity and temperature sensors will function in practice.
How exactly will they compensate for being in my pocket, hand, etc?

Possibly but it's my guess this is a pretty standard if not crude gauge. I doubt it has the capacity to offer variables or degrees (pun intended) in working out temperatures from pockets to real room, let alone being a bog-standard gauge.

It's more likely that it's reading Celsius and the developer didn't convert it to Fahrenheit. It is that high b/c of her hand (body temperature is about 36-37 Celsius) and if she left it alone on a table it would probably register close to room temperature.
The idea of compensating for a hand or pocket is impossible. Therefore, the quality of the temperature sensor can be based only really on how long it takes to register temperature changes.

Agree, not even sophisticated temperature gauges have an ability to ascertain heat outside of it's own source. It would require a sensor to be placed directly where it needed to relay the information back to.
If you want to see an app that utilising the baro sensor and gps, check out xcsoar flight software, where altitudes have to be barometric for airspace levels.

Sir I have installed some custom ROM.
After that I lost my Thermo hygrometer sensor on S4
The readings are like this after running HWModuleTest:
ACC RAW COMP
0 34.48 0
Before installing rom the readings were
ACC RAW COMP
3 34.48 16.7888
This means that something happens to thermo sensor.
Please help How can I correct that.
From where I can get back these ACC and COMP values.
Please help me soon.
I'm not the person you quoted, but the simple answer is to go back to stock, if you haven't already done so. Your custom ROM possibly doesn't support the sensors.

Altimeter accuracy?

Does anyone know how accurate the altimeter is?
Every time a do a manual calibration, the new value is way off from the old value. Several dozen feet sometimes.
Has anyone tested it for accuracy?
I got the same problem too
And I'm in the same situation as you, I'm searching if anyone tested the accuracy of the altimeter :/
I havent found anything yet man. If you do, please post. Thanks!
When I refresh the altitude at home, I get 130ft. Checking my elevation against a geological survey source, I get 136ft.
When I'm at my vacation home on the coast (of Maine), I get 10ft.
Good enough for me
Reality test
I was skydiving yesterday and tested my Gear S3 Classic along with 2 specialised altimeters: Barigo and Neoxs.
Tried 2 apps: native baro-altimeter and Skydive altimeter metric by Jean-David Hsu.
Manual calibration and altitude set to 0 beforehand.

No, the app keeps the screen alive all the time. The hand on the watch face is visible all through the jump. I put some magnifying screen shots in for better perception. Try watch the vid on PC. Must be OK.

Sorry, what I meant by "it is off at times" is that it is not always accurate? I could see that the watch was on, but it was hard to tell if was the same reading as the "real" altimeter.

I should say it IS accurate! In most cases Gear S3 performed better than Neoxs (professional skydiving altimeter). Screen shots show that the difference between Barigo and Gear is minuscule and Neoxs is approximately 100 meters wrong at times.
So, I was pleasantly surprised. The watch rocks and no mistake!
I live 200M from the coast. Setting up the Gear was easy at sea level from then on mine has been as accurate as can be expected for this type of device.
I have owned nearly every smart watch available being a watch nut and can say to date the S3 is my favorite of this type of watch. Very well made and in general a quality advanced piece of micro engineering. One to be proud of.
Ryland
The altimeter on the S3 is a fake, same as barometer. To prove it, just disconnect the watch from your phone and prevent internet access. Data will then be totally inaccurate with huge variation during the day even if staying at exact same spot.
Samsung is just using the GPS data location to get more accurate values, but wht is inside the S3 is dumb

Disppointed with the Barometer/Altimeter App

I am very disappointed with the Samsung Barometer/Altimeter app, The barometer only registers in whole inches of mercury. All watches I had in the past, register in hundredths of inches of mercury. I wonder who else feels the same and would like Samsung to fix this error or maybe a developer could create a replacement app.
Edit: They finally updated the app and it shows the barometric pressure in 100th of a inch of mercury. Big thumbs up

I agree. Hopefully Samsung does address it. Meanwhile I found a free app called "FBarometer." Just search/install via Gear app. Seems pretty accurate, doesn't register in hundredths but does do tenths so a step up from wholes inches at least.
I have a feeling Samsung rushed to get this watch out (obviously, everythings backordered now it seems).
I have a feeling there will be many updates in the near future. At least I hope so.
If you touch the barometer to display the trend look at the outside ring, the barometric pressure is displayed gauge style with a red dash marking the pressure and the units are to the hundreds place. It's still not great but you can at least tell the difference between 28.5 and 29.
I live 77m above sea level and my watch shows -97m, a bit out me thinks.
Barometer and altimeter are useless. I live between - 90 and plus 154 meters, in Amsterdam which is - 3. Consequently also the floor counter is facked up.

You can use another very good app called Barometer & Altimeter. I use it when go mountain. I talked to author this app before download it. It was tested by a few climbers and created with help mathematicians and physicists. The measurement error is < 1%. It is better than my stock altimeter GPS-based. Very good app, absolutely worth buying.

I totally agree! Looks like the sensors that Samsung has choosen are totally pieces of crap.
Altimeter: from my sofa 5m... couple of hours later 35m!!!
Barometer and heart rates are also giving vera random figures compare to 'real' hardware.
Samsung just wanted to show more features and be in line with competition but it does not work.
They better should have left very useful features that were present on previous model likre IR Remote that I had on my Gear 2 Neo!
I will never understand Samsung when they decide to replace features in place of add new features. Mainly when they remove very useful and working gears and replace those with unreliable sensors....
You do realise that the altimeter is air pressure based right?
If the air pressure has changed during the two hours you were on the sofa then the altimeter will show a different reading.
That's the whole point of calibrating it before you set of on a climb or whatever you're up to.

Yes it's barometric. And altitude jumps all over the place even when the pressure is constant. Eg walking up the stairs, 2 stories, results in a climb of -12 to +30 meters, should be - 3 to +4. And my daily run which is totally flat at - 3 shows 116 meter hills. It's true and authentic crap and I'm gonna replace for the Fenix 5 as soon as possible!

Thats why shealth thinks i climbed 10 flights of stairs while just walking about for nine hours.
To those who think that their Gear S3 sensors are any accurate, just try to disconnect your phone Position/GPS or to use the gear S3 alone. You will then see the truth about those very inaccurate sensors that Samsung has put in the Gear!
They are only 'providing' you with accurate figures when position/gps on your phone is on, in other words, the 'accurate' info you are seeing are provided by internet data, and not by the sensors themselves... Shame on Samsung for that!
i have the same issue. at 155 ft above sea level, but watch states between -150 and +435
it also only counts 1/10th of floors climbed
I don't get accurate floor counts but I know for a fact the gps works well without my phone. At least the golf app I use gives me accurate readings in standalone mode.
Sent from my SM-T530NU using Tapatalk
Same here. I stood outside under a clear sky around 30m above sea level. Tried calibrating thrice but each time it says -7M.
Skydiving
I have used the S3 Frontier when I skydive along with my Viso II Digital Altimeter and they are within 25-50ft of each other. This is without the phone. It is actually pretty accurate. I do not use the built in app. I use one from the store called Skydiver Altimeter. It works great.
Well no clue about others.. but just got mine and comparing with two others one ming Suunto and its like some others pretty darn accurate. Just going up a few feet.. was spot on. I wonder if like the phone you need to reset it at now and again.

Keeping altitude on display

I want to try the altimeter during a flight, but I can't keep it on display. If the watch return in AOD mode, it comes back on the watchface if turn my wrist, not to the last application as Altimeter. Is there a way to keep it on display ?
An alternative could have been to put the altitude as a complication on a watchface, but no one include it... I can only find the pressure...
A pressurized cabin won't give you an accurate altitude reading. Typical commercial airliner cabins are commonly pressurized to about 6000-8000 ft.

Or you could turn the screen time out to maximum time.
You could make your own watchface and put the altimeter in it...
There is a watch face with altimeter alread...

Now I understand why my watch only went up to about 2300m when i tested it on a recent flight. thanks! I thought it was broken!
I had the same problem. I wanted to use the Altimeter for paramotoring. Someone on this forum kindly directed me to a Gear app called "I am alive".
Install the app, open it and switch it on and leave it running in the background. Whatever app you open after will now stay on screen. Works great.
Thank you, I am Alive works perfect
