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

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...?

Hi all, have somebody thought about simulating the accelerometer using the phone camera? It's possible?
I couldn't find anything about this, sorry, but i'd be really happy to know that there's someone coding something like this...
PS: sorry for my poor english
i dont see this happening at all... i mean a image is produced by using light... how would that information tell u which way or which angle the phone is on :S

Ok, but as the image moves the phone could know how am i moving it
Theoretically, it is possible. It would just be a huge battery sucker and not too accurate. I came across this game a long time ago, back when I still had my Titan (no accelerometer). It is called 3D Lawn Darts. It uses the camera to control your throws. Check it out:

It could work but only in a room covered with reference points all over the walls and floors like they use in 3D capture! LOL
I think the phone proccessor would choke on the proccessing! lol
there's a free app (i think) called CCSnake. Search for it. If you can't find it. Then search for Camera Controlled Snake. I tried it but the controls are not that good.

well not really.
Camera take as picture, then asks the user to set a referance point. somthing that stands out. It takes detaisl of that area (color shape, etc)
all further images are taken and referanced to that point. and the program then knows which way the PPC was turned. if you want rotaion then you just need two points.
For all movements just 3 referance points are needed.
This is very basic movemnets and your limited to the area you are in as the camera must see the original points. but it would work.
i saerched for this a long time and tought: maybe you can do it with an other part of the phone.
or maybe you can make a program to use this as a normal g-sensor with new accelerometer software.

There was a game that I had on my old Motorola E815 that did just this. I think it was like a marble tilt game...it worked fairly well as long as you didn't move too fast and it wasn't too dark (or light for that matter, as the camera on the E815 was really mediocre).
I have been looking for a compass app for ages, is there any decent ones out there?
geee, when HTC actually put a magnetic compass sensor in a phone, there might be an app to support it...
Shouldn't really be a problem for a nifty developer if based on the same principle as a waterlevel with the G-Sensor. Just need to calibrate it yourself to, say North, by using another compass or GPS and voila.

Ahhhh... I thing the G sensor works on the vertical plane not the horizontal plane that would be required.
I use GPSTuner as compass and I think it is a satisfying solution don't you?
Obviously it is far from being a fast and smooth compass as it is an Iphone 3GS but whatever (fortunately, I don't really like exploding screens xD). You can also buy a real compass...

WMMiniGPS will do the trick for you.
There are a few others that will use the GPS to show your heading. You can find them here.
A GPS tool will show you the (correct) North only if you are moving.
Only if our device would have a magnetic sensor inside, we could have a software repeater on the screen. Otherwise all we can have is a fake. Unfortunately... A pseudo-compass.
all the best!
Thanks guys! I'll check out those apps, but it looks like I won't be throwing my SILVA compass away just yet!

Yes, Yes. GPS will give you course (derived), not heading (It doesn't know which way you are facing, just which way you are going).
the omnia 2 has a compass and a compass app. maybe you can pull it off of that. why go through the effort of putting the compass hardware in the device if you dont give apps to support it? maybe google will make the next version of maps capable like the iphone and android.

Indeed. Fortunately, HTC did *NOT* put compass hardware in the TP2, and therefore, did not waste any effort.

i use igo8 nav software for my compass..a standalone compass would i guess be useful...but our phones have gps built in..so ur gonnna need gps software which in turn have compasses..i didnt like tomtom7's compass but igo8 on the other hand has a very solid compass, and amazing 3D maps so...
Great Compass App!
"Where is" has a great compass in it. You have to be moving for the gps to pick up your speed and then the compass works, but even just walking is enough speed. Compass is very accurate too and great looking compass too...http://simosoftprojects.com
Never seen this posted here because, and I didn't the answer with search.
Why does Google Maps not auto-turn? It does on the iPhone 3GS and 4, yet not on Android. Android is made by google. :|
Is it because of the compass in the iphone; does the evo not have a compass?
Auto-turn??????
I think he means that it doesn't change orientation when you turn, north is always up. We have turn by turn nav though.

That's my biggest gripe with the evo..well, that and the battery. I wish google maps orientated in the direction you are facing like the Iphone does....I did find an app called Rmaps that does it, but it is definitely not as polished as the Iphone. Seems strange that a google phone would not have included it?!

While the gnav is super cool, especially in places that you haven't drove before, but a lot of the time, If I'm trying to get somewhere locally, I just want to see the map because I already know the area, but the damn maps never move.

Polished? Maybe things are different with the new iPhone, but I have the 3GS, and unless I was walking, it virtually never oriented in the same direction I was going. It was usually about 90 degrees off.
The Navigation app uses GMaps and orients with you.
It is the Polish for driving.
Click the compass. It changes from N-S to turn.

Compass moves to indicate what direction you are going not where North is.
Listen to the guy and just click the dang compass! This toggles the map from top-down north orientation to a 3d directional orientation. You must be moving to see the change.

Use navigate instead of maps. Then you will see a compass.

That's where the confusion is--there are THREE options in gmaps--map, directions and navigate. Map does not have a compass and does not give you turn-by-turn directions, directions is just the text listing and navigate is the turn-by-turn with voice directions and the compass. And it all works (even the compass switching)!!!

Yes true that there is no compass but really you can't expect all the sensors and high end configs for a mid-ranger. It is a mid-ranger and it will have some cons. As far as I see it, maybe the NFC would be a drawback. I wouldn't really worry about the compass sensor. I don't think it would be useful very much. But its just my opinion, you may need it.
But compass is a fairly basic sensor......
Does it mean there will be no navigation support on G4 (Plus)?
Will the gyroscope help?
Yes, I am also just worried about navigation. Is it possible for Maps to direction based on Mobile Data/Wifi in the absence of magnetometer?

I do believe the Gyro would be suffice. Even the G3 didn't have one and I think not many people complained of it. They were able to navigate without a Gyro too. I am not sure how the compass sensors work or how useful they would be but I don't care anyway lol

The gyro won't help. However, the compass isn't necessary for navigation. The GPS is what you need, which can locate you wherever you are, so it can tell what way you're going. If you really need to know what way is north, South... and it's nighttime do you can't figure out from the sun, you'll need to open up maps, and start walking, and you'll see in what direction you're moving.

I asked the compass question in motorola's Forum and this was Matt's answer:
No, it does not have a compass/magnetometer. It does have GPS but won't support a compass app.
That make's it a NONO for hiking because a low speed or standing stil at crossroads you definitely need this to show "the way" aka rotate the map or the guiding arrow (like in Locus Pro). GPS does this at speeds above maybe 6 km/h.

Of course. The only issue would be with the cardboard v1, where the button, which was two magnets that didn't even touch the screen, wouldn't work as the phone doesn't contain a magnetometer (aka digital compass). Though even many phones which do don't work because of the placement.
