Three-axis gyroscope on the nexus....

is the Three-axis gyroscope on ur device accurate?
mine for like 1 minute shakes alot then after it stil shows a wrong direction and if i move it a bit shows a diferent but stilll eronated direction
is there any way to recalibrate it?
i played a bit on a iphone 4 and was very very accurate.....

what are you using to view the orientation and information from the gyro

firstly i tried google maps navgation then i downloaded anoter 2 free aps gps test and gps status...if i hold the phone in one position it shows me one point as beeing the north...if i do a 180 degrees spin it shows me another point as beeing the north
ps i think its the digital compas thats foulty not the gyro right?

You could use the app Phone Tester it gives you a reading of all the sensors, but that's it.

This thread warrants an explanation of the differences between GPS, compass, and gyroscope.
GPS: Tells you where you are. It can be used to infer the direction in which you are moving. It can NOT tell you which way you are facing.
Compass: Tells you which way you are facing with respect to the Earth's north/south poles.
Gyroscope: Tells you how fast you are spinning about each of 3 axes (hence why it's called a "3-axis gyroscope"). It can be used to infer the direction in which you are facing (albeit not easily).
Neither the compass nor the gyroscope can tell you where you are, or the direction in which you are moving.
The problem you are seeing is with the compass, NOT with the gyroscope. Google maps does not currently do anything with the gyroscope. The digital compass can be calibrated. I use the "Compass" app, which has a calibrate function.

It's a 6-axis gyroscope, not 3.

No it's not a 6 axis. It's a 3 axis. It's listed here: http://www.google.com/nexus/#/tech-specs.
-----------------
Also general question/comment. Doesn't a gyroscope help the phone know which way is down? So technically you can have an object shown on the screen, then you can walk around that object with your phone and see all sides of the object. (Like the iPhone 4 demo Steve Jobs did with the game Jenga, he walked around the tower to see all sides)

@ ravidavi
Thanks mate yea thats it....the compas is all messed up...
On ur phones dose the north apear to be in same direction no matter witch way u turn or is this a wide spread flaw

The compass needs to be calibrated.

There's no such thing (in this world) as a 6-axis gyroscope. What you are thinking is the oft-quoted phrase "6-axis gaming sensor" (or 6-axis motion sensor). A 6-axis motion sensor is actually a chip that combines a 3-axis accelerometer and a 3-axis gyroscope into one package.

A gyroscope only tells you how fast you are spinning about an axis. An accelerometer can (for the most part) tell you which way is down.

I would like to know what these guys are using to test the gyro on the NS.. Actually I am not sure this app is actually testing the app or the compass / accelorometer.
any ideas?

Did that woman say the phone had a barometer...?

How's IR Blaster? Did you get it to work with your TV? Also Any performance issues Lag etc?

I'm at work so haven't tried that feature.
No apparent lag...the screen is beautiful, but my other phone is the Optimus G so this is not noticeably faster.

One of the things I hate doing is swiping a whole bunch to scroll through length webpages or forums.
Have you used the smart scroll feature to surf any pages? How well does it work? Does away with all the swiping that is normally done while surfing on a smartphone browser?

Have you tried the NFC? I assume it works in exactly the same way as GS3...?

Also, could you take pictures of the phone itself? In addition, a picture of the apps that are in the drawer immidiately upon boot?

Just tried it on a few pages...it seems to work really well...I guess it is based on the angle at which it thinks your eyes are looking at the screen so you can trigger it by tilting the phone. I can scroll up and down an entire page without touching the screen, and stop wherever I want to read something.

I'm not a big NFC user and didn't have a GS3, but I just sent a web page from the S4 to my Optimus G and it works the same way I remember.

Unfortunately it started downloading all my apps I have ever installed on my play account as soon as the phone cranked up.

In my best fake Australian accent...
"What a beauty!"
Thanks for the pics!

Could you take a pic of the battery vs. the S3's battery? or just the battery of the S4 if you don't own an S3. How's the movies quality on the S4? Thanks.

LTE speeds? and area you are testing?

No S3 here...My old phone is the LG Optimus G
The screen is great, movie quality is awesome, HD!

It's definitely nice, the screen is probably it's best feature. My other phone is the LG Optimus G so the S4 is not a big spec jump. It almost feels too light, but I am attributing that to the fact that my OG is a slab of glass.

Could you give us a real world example of the "dual camera" feature? I guess you simply have your face over whatever picture you took with the main shooter? The reviewers are excited about this feature, but I can't figure out any practical example of why this would be useful...
Maybe it's just me

Maybe if you're filming a video and you want to talk about what you are filming? Maybe showing the reaction on your face to whatever it is you are taking a picture of. Video reviewers will like it because they can show their face while recording their review.

I'm definitely with you on that....the only thing I could see it being useful for is capturing your reaction to the picture you are taking...? It actually frames your face in a postage stamp and overlays that on the rear camera picture. I guess they are trying to make the picture taker not feel left out of the picture.

[Q] S Health Calibration?

S-Health's pedometer is pretty much useless. Is there anyway to calibrate it?

Have you updated the app? Try that first if you haven't. It updates under the Samsung app store, you have to log into your Samsung account first before it will let you update.

Mine is very accurate. I've measured my distan c.f. e walked with an odometer and it matches my s-health numbers. I also used it on a treadmill the other day and distances matched also.
Sent from my SPH-L720 using Tapatalk 4 Beta

Sometimes, it's amazingly accurate. I'll run exactly 3 miles and it tells me I've gone 3 miles. Another day, I'll run 4 miles and it says I've gone 400 steps. I wonder if it has to do with how it's positioned on the body or something like that?

I use mine on my hip in a holster. Never had a problem.

Make sure your gyroscope is calibrated also.

Hi All and thanks for the responses.
I did recently recalibrate the gyroscope and it did not help. I usually hold my phone in my hand while running. Is that a bad thing to do? What is the best position?
I downloaded Accupedio (?) and it was far more accurate than S-Health.

I wear my phone in an armband on my bicep, and as I said, that's not terribly accurate. This morning, I ran 3 miles and it currently says that I've gone 317 steps, most of which were probably between my car and my desk. I'm going to guess that it works a lot better in my pants pocket than it does on my arm.
Of course, I don't really care about the accuracy of S-Health. If I wanted to accurately track my runs, I would use MapMyRun. If I was concerned with tracking steps, I'd get something like a Fitbit.

I've given up on S Health. I have it updated and yesterday had the phone in my back pocket on the treadmill and it was still way off. I had Accupedo running also and it was very close to what the treadmill said.

Faulty compass

Does anyone else get the following:
1. GMaps not recognising the compass and not turning its compass as you turn round;
2. Compass app goes mental when you test by spinning round (mine spins the wrong way then back randomly)
?
Looks like my Note3 is proper fkd. At the moment it's just peeing me off.

Sounds like the Note 3 is suffering from the same compass issue as the S4. The compass just needs to be calibrated. Download GPS Status & Toolbox (excellent app!) from Google Play Store and go to Tools/Compass calibration. That should fix it. Calibrate the compass outdoors away from metal structures for best accuracy. Factory reset resets also the compass calibration data, but luckily the calibration takes only about 10 seconds or so. Hope this helps!

Cheers Pete.
I did try that but it's still flying all over the place.
Sending it back as faulty. There's too much I dislike about this phone to make it worth £620.

I tried with mine and a few demo units from the stores.
After a thorough test, they all essentially have this problem. My one, when you go to *#0*# it would just either not spin or spin sporadically, same with the demo units.
I guess it's a software problem, 4.3 problem essentially, my AOSP'd Note 2 also has this problem

Oh right okay, so you yourself had the same problem, but probably some external reason not mainly because of this, you sent it back and issued a refund?
I have a feeling that when I leave my house, there is a lot of magnetic interference because my compass always works in my house :/

Heh. I hope they sort it out for you.

I'll be sending this device back and getting a replacement, since Rogers has a 15 days return policy if under 30 mins talk time, I'm gonna exchange for a brand new one and see whether that helps

Got a brand new one! If it still doesn't work, well then screw it, I guess a software update would fix it.

My new device still has this bug, but calibrates faster than my first one. It's a widely known bug, maybe Samsung needs to fix it.

FWIW mine has the same problem. I did manage to get it work work correctly for a little while by using a "metal detector" app which vibrated when it detected something. It suddenly started behaving correctly for a short while.
Calibrating it with the GPS Tools app also fixes it for a little while.

Having the same issue with my Note 3 as well.The GPS Status app using the compass calibration fixes the problem but once you restart the phone the compass no longer works again and you need to calibrate once more.
It seems like a software bug issue rather than a faulty compass.It's annoying but at least there is a solution.

What is the meaning of that?

When I logged in test menu trying to test heart beat sensor that was the result...what is this all failure ??

Nothing to worry about. Depending what the sensor is looking at declares what passes and fails, so I'm guessing the test requires a specific object to look at for everything to pass.
Sent from my SM-N910F

But this is self test without any thing need to do from me

If you put your finger in front of it, a piece of paper, light/dark room etc. All yield different results, so I would think samsung have a unique environment for the sensor to pass all tests.
