Hey peeps!
I have this new idea for a app that runs on phones with secondary front cams.
Unlock the screen by it doing a face recognition of your face, no need to passcode or pattern lock it...
Hope to see it soon.
If an app like this is alredy available, please post it here, if not - DEVELOP IT AND POST IT HERE!
thats a great idea, the tech already works well enough on laptops so hopefully some bright spark can make it a reality
Would it always have the camera running or only when a button is pressed. I can definitely see this being possible and not too hard to dev.

Exactllly! And still, only noobs like me are seeing seeing this stuff... Some real programmers! Do this!

Camera will wake up as soon as the screen wakes up, and if it sees you, it should unlock.
This is a great idea for an app. Unfortunately, I don't have nearly enough coding skills to pull off facial recognition...
...and I only have skills to successfully use it
It would need something along the lines of Google Goggles recognition software.

Maybe someone can rip off the api's from goggles and make it work offline
Not a bad "concept" but not likely to be done until Gingerbread is used by all the phones.
You see the api to access the ffc on Froyo is very phone specific wich would only make this app run on the Galaxy S (other phones would work also but with a lot of work).
Second problem is how would you unlock your phone when it's complete black (I mean no light at all) would be a very stupid situation to find yourself in isn’t it ?
The sight of my hungover face first thing in the morning is enough to make my phone go to sleep for good lol
Nice idea though, might have an issue with varying light levels though

Can't light sensor and screen work together to bring the enough light for camera to work?
Great idea of an app
Hi guys I have a problem with gio's accelerometer, i found out about this in a game: by entering *#0*# and going to sensor I noticed: while the phone is lying down still on a level surface with no vibrations accelerometer data is changing and it never stops. It is not important in normal use but in some apps and games this is realy a problem.
So any solution?
ok ...removed.!!!
Try to go Settings->Display->Horizontal calibration
Or try to change the ingame titl sensivity
On my phone accelerometer data also chanching but really a little bit.

Demanding much?
You come on a volunteer, community-based forum and complain because you haven't been answered within two days?
What troubleshooting and testing have you done?
Is it on all axis?
Does toggling the different radio have an effect?
There could very well be issues with your Gio alone.
This could also be a problem with a driver for which we don't have a source to look at.

sorry to say that,I had a bad day.
well yes. I tried anything and it is the same.
I wonder if this is because of hardware.
even in htc hero accelerometer works better than this.
Hi
I bought the Note II 2 days ago, and I ended trying Google Street View in compass mode... Nice software...
As probably you know, in this mode the orientation of the handset controls what you see on the screen, offering a better 3d experience than simply sliding your finger on the screen to change the viewpoint (try it: maps --> select a place with street view available --> enter street view mode --> press "menu" left virtual touch --> select compass mode, and play with it!).
This is all nice and well, except that I experience on my phone a serious random jitter (mostly azymuthal) in the street view: a few degrees more or less, not much but enough to make you dizzy after a while. This happens also in Google Skymap.
I tried to recalibrate the gyroscope, also had a look in the hidden "test" menu (dialed *#0*#), and installed marketplace compass apps which offer calibration tools... to no avail. I also changed position in my flat to check for stray magnetic fields effects, but nothing new.
I know there are other devices forum threads where this type of problems is explored (not much as far as i know), the point here is I would like people with Note 2 at hand to check if they experience the same type of problems: I'd like to know if this could be related to a hardware problem, or if it is another screw up by Google/Samsung ...! :silly:
What do you think ?
Same thing here, I've had my T-Mobile GNote2 for just under two weeks and when I tried the compass this am I found the same jitter you describe, using GPS Test app and the diagnostic mode you found. Started a thread in T-Mobile GNote2 here, looks like it wasn't a priority for Samsung.
I'm getting gitter in Street View too. Damn annoying.

Bad jitter here too .... and this was one of the features that seemed best to try out on the larger screen... Hopefully there will be a software fix. If some people would post that they have no jitter in street view compass mode, then I'd go see if it was just my/some units with the defect and exchange while in my 14 days.
I can confirm the jittering on my Note 2. It's pretty annoying. Calibration hasn't worked for me.

In other compass apps, I can't experience any jittering. So I think it must be directly related to Street View and how they read/process the values from the compass. Maybe the interpolation is wrong?
Well, I can tell you that I exchanged TWICE my Note II since I posted the problem on the forum (one was exchanged for another reason)... and the jitter was and is here on the three handsets.
The last one I got works marginally better, but the effect is still quite annoying.

I tried a few compass apps. They mostly had the jitter as well... and the *# test menu showed the same jitter back and forth on the compass :=/
Are you all running on stock rom and kernel? So maybe we can isolate the source for the jittering.
Jittery here too... On stock rom/kernal

Hm, stock rom/kernel...why doesn't Samsung test this stuff before releasing. Now we need to find out, if it's a software failure or a hardware problem. I have tested this compass app and there is no jittering. Can anyone confirm this?
Search for "com.apksoftware.compass" in the play store. Cannot post external links, as I'm quite new.
I have slight jitter in compass mode on street view too.
Stock ROM, no root.

I've tried several other stock/non-stock roms and kernels. All have the same problem. Has anyone contacted Samsung about this?

That's exactly what I'm saying! I actually called Samsung's main technical services department and the person I spoke to didn't have a clue what I was on about, so I had to describe it to her carefully. And by the way, yes I've tried it on all the available compass apps on the play store and they all have the same issue. To compare, I used my dad's S3, totally fine. This is one of the reasons I bought the phone in the first place, to use the street view in compass mode after seeing it on the S3 but its a total letdown, which leads me to believe that its very likely a hardware issue, and that's what I'm dreading.

Maybe it also could be a software problem. I don't think that Samsung includes defect hardware sensors in all of their Note 2 devices (therefor they have extensive hardware tests). I hardly believe they hadn't had the time to write a proper kernel driver with interpolation for the magnetometer. And probably all other kernels base on the kernel sources, Samsung has published. So this could be an inherited problem. Would be interesting if the Note 2 and the S3 share the same magnetometer sensor. Can somebody elaborate on this? If so, then we need to compare the kernel sources for both sensors and try do debug the problem step by step.

they were probably too busy making the rest of the phone as awesome as it is :laugh: ps - im getting the jitter as well

So you're telling me this problem may be fixed with either a 4.2 or 5.0 update? One can only wish right now.
Jitter here too. Very annoying. Quite shocked this got past QC.
Tried multiple roms and kennels, always the same.
Well I'm now on stock 4.1.2, and sad to say its the same problem. Absolutely nothing has changed. I think we're stuck with this issue guys, such a shame
it is a big samsung problem. it is on the S3 as well...
I had the same problem. I tried several compass applications from the market and celebrated the compass several times. The only thing that really helped to get the digital compass get stable is to turn off all wireless functions, including the phone, as well as the phone sound and power saving functions. I turned off anything that might produce a megnatic field in the phone, and then calebrated the compass again. Now the compass works fine after turning on everything.

I have been trying to get this feature to work but have no luck yet i have seen videos of how to activate it but cannot get it to go any one else have issues with it or just me?
Try the calibration of gyroscope

Hi, your gyroscope may not levelled or paralleled along horizontal.
Please try to calibrate it.
Gyroscope calibration is located inside advance setting.
IMO, if your gyroscope is levelled 45 degree along horizontal your quick glance will activated only if your phone is angled 45 degree along horizontal also. BTW, you can use the quick glance while holding it, other user think it will not work but actually their gyroscope is just not levelled along horizontal.
If you think I helped you, please pay it forward.
With any kind of favour,
many times as you like.
Until your spirit bright sparklingly.
Greetings,
I was told by a comrade that XDA is the realms for us, mortals, to seek for guidance and enlightenment.
So, I acquired my new LG G3 last night. Everything is flawless and almighty, except for the compass: It won't point to the correct direction. It is always 90 to 180 degree inaccurate. This sure is a big letdown as I depend on navigation features frequently.
I have tried calibrating it with numerous apps like Compass, Bubble Level, 360 Compass, etc etc (basically most of compass-ish device out there) but none of them does any good.
Anyone out there experiencing the same matter? Is it possibly software issue? or maybe hardware issue? Is it fixable?
For additional informations, I include my phone informations here:
Model number: LG-D855
Android version: 4.4.2
Software version: V10h-EUR-XX (updated to the latest version)
I humbly thank you for the help
I take it you have done the mandatory twisting and turning figure of eight movements to put the sensors through their calibrations?
I find it takes a good few minutes before I have an accurate reading.
Decent compass apps I use are 'Field Compass Holo' by Chartcross Limited and 'Compass' by Espengineer.

woaaahh, it works, Sir! It works!
I have previously done the eight movement calibration countless times with different apps but never worked.
Then I attempted with the apps you suggested, and voila..!! Compass works perfectly now!
Please accept my humble gratefulness, Sir. I bow before you. Thank you

No problem... Pleased you got it sorted.
I have the same problem with my LG G3, do you mind going into more detail about how you fixed the compass?
