Anybody got chance to play with the new 6axis motion sensor?

This is the biggest motivation on my side to buy Vibrant to be frank. I am a casual developer and would like to write some acc+gyro related application on my own phone.
As far as I know, Vibrant has 6 axis motion sensor, which should be 3 axis acc + 3 axis Gyro if I didn't misunderstand it. However, I can not get any information from internet about what's the model the sensor is, and I'm not sure if this sensor is of exact function as acc+gyro. So if anybody happened to know such kind of information, please share it, my purchase decision would be definitely based on this.
Thanks!

If I remember correctly it is actually a 6-axis accelerometer. It gives you angular acceleration instead of angular velocity, which has it's goods and it's bads.

Thanks Lutin
I'm not sure if it's Gyro or not. There are two posts can be referred

Based on what I saw, I guess most people are still confused about its type. This is why I was wondering if anybody knows the actual model by chance

There's no gyroscope in Vibrant, Captivate, Fascinate, Epic,...
just triaxial accelerometer from Bosch and triaxial geomagnetic sensor from Yamaha
Exactly the same sensor set with Galaxy S UK and Asian version.

Are you sure? This is totally different from what them claimed. They said they have something other than just digital compass

100%, sir.
I own both Galaxy S UK and Vibrant
I used some different software and *#*#0*#*#* code to check on both devices. I'm not surprised to realize that there's no gyroscope.
But the Yamaha geomagnetic is superior to almost every smart phones on the market right now (bi-axis). It's a tri-axis sensor.
I suppose that the combination of tri-axis geomagnetic sensor and tri-axis acceleration sensor will be equal to gyros + accele in iphone 4
Sorry for my English.

thanks man, you saved me a lot of time!
I played with one Vibrant today and yeah, it's magnetic sensor. But it performs basically the same as Gyro, just will be affected by the metal thing.
I have no idea how good it would be in real use and I am still thinking if I should give it a shot.

Laser ruler

I had an Asus Zenfone Laser 2, based on a SD 615, but with 64 bit Android. That phone had a similar front camera setup, in the sense that it used a laser beam to measure the focus distance for short distances.
What was kind of neat it was that they added an app called "Laser ruler" thatbwas using the camera sensor to measure distances to various objects in close proximity.
Well that app won't work on our 32 bit Android.
Does anyone knows of a similar app that could work on our G4 Plus?

app that uses Infrared scanner as camera/nightvision?

Since the Note 9 has an Infrared iris scanner, I am wondering if there is an app that can use the scanner with visual, like a camera or night vision. Off course small distances, just for fun.
Something like this on the Poco F1

Bump

I've been lookig for something like this since the s8, and I havn't found anything

That was custom done by a dev or app maker who has the Pocofone...
You could always ask them to hep but as they don't own the Note they probably won't do it all...

Redmi note 7 Vs 7 pro? Real camera advantages?

Hello, I am really in doubt on which one to buy. My real interest is about the camera : I haven't found a single comparison between the Samsung and the Sony cameras of the two devices. Do the photos of the pro version really justify the 100+$ of difference and the missing b20 band? Right now I have a redm note 3 Pro and it's perfect for my everyday needs, so a super SoC or a lot of ram would probably be wasted as I don't play at all with my phone. Any advice? Thanks!

I'm also curious. I watched hundereds of comparisons and from what i understood the sony sensor offers better dynamic range and sharpness. Depth of field (background blur) is same due to same sensor size.
By not a higher margin btw.

Do you have link??? I would like to see results. And also Gcam results, if it is not only in app.

S20 vs S20+ (ToF)

Hi to everybody,
I would like to pre-order a new S20, but I am undecided between S20 and S20+ (I discard S20 Ultra, because of size and weight).
I would prefer a smaller and lighter phone, don't care about having a huge display. The difference between S20 and S20+ are screen size, battery and ToF sensor. About the last feature, I would like to know what I really miss if I get the smaller S20. Does ToF sensor affect camera picture quality? I don't know very much about it, just that it is used to measure distances. I care about the camera features and photo quality, so my questions are: Does S20+ take better pictures than S20 because of ToF? What's the real advantage of having a ToF sensor?
Thanks a lot

ToF helps a lot with portrait photos.

So S20 cannot take blurred-back Portraits?

Google:
The 3D Depth Camera is a Time of Flight (ToF) camera on (new/upcoming phones) that can judge depth and distance to take your photography to new levels. It uses the known speed of light to measure distance, effectively counting the amount of time it takes for a reflected beam of light to return to the camera sensor.
Also Samsung/Google:
ToF Camera is used with Live focus video and Quick Measure, letting you add more creative flair and get information in a way you've never seen before.
In the case of Live focus video, you're now able to blur out the background in real time as you take a video, adding a brand new vibe to your movies. You can even swap between foreground and background focus with ease, to switch up the focus with a tap. Live focus video is available on both the front and rear cameras, so simply open the Camera app and swipe to Live focus video to try your hand at movie direction.
With Quick Measure, the camera acts as a 3D camera, judging width, height, area, volume, and more when you put an object in frame. Quick Measure is a preloaded app on Galaxy S10 5G and Note10+ (etc, and soon S20s), so open the app and put an object in focus to get a real-time measurement right on your screen.
*The Quick Measure app is separate from the Camera app.

Of course it can but ToF helps with the edge detection.

Even pixel 3 has a single camera it will take great portraits. With the help of TOF camera, the subjects stays clear and the edge detection will be better.

Another difference is that the regular S20 has a more limited 5G. It won't be able to support the fastest speeds. You might not care about that either, but it could affect the resale value specially in a few years when 5G is the standard.

You have that backwards... The S20 doesn't support the 'slower' 5G speeds...

Nope.
"The Galaxy S20 only supports sub-6GHz 5G, while the S20+ and S20 Ultra add millimeter-wave (mmWave) to the mix. Sub-6GHz 5G offers better coverage and can penetrate through buildings better than mmWave, but it's slower and has higher latency. That means if you want the fastest speeds in the most places, you'll want to opt for the Galaxy S20+ or the S20 Ultra. "

Thanks, it's worded differently on other sites where they mention you'll only need the Sub-6GHz band since it's much more likely you'll connect to that versus the mmWave.
