I just downloaded an app to check out all the sensors and I was surprised to see a magnetic sensor on the nexus 4! I know the 7 has one for a flip cover. Is that why the nex 4 has one?
The question = Why does the Google Nexus 4 have a magnetic sensor?

I'm not saying it is bad or good. I just wonder what it is for.

Compass?
What's the app?
Technical specifications of the phone list:
Sensors: Accelerometer, gyroscope, proximity, compass, barometer

I think your app misreported the compass for a "magnetic sensor".
While we are here, the actually weird sensor here is the barometer. I am suspecting it's assisting the GPS to determine height (for hikers, for example). Or someone can also write an apps that tells you if you're in the middle of a hurricane or a storm

Well I mean there are weather alert app.
Also, yes it can detect metal, you can download metal detector app and it probably go haywired if you are in the middle of a magnetic storm too. Also there are apps that can detect your heartbeat base on the changing color of your skin by using camera and led flash.
You can't be serious... How did you think compasses work? Magic?
I never thought of that..

They put a barometer in the Gnex, which they said at the time was to help the GPS in getting a quicker lock (as you say).
I don't think any apps ever really took advantage of it though, or if they did I didn't notice any difference.
'Magnetometer' is the correct term for the 'compass sensor'.

What exactly do you mean my grainy? Looks fine to me from what I can see.

1) Check that your back cover glass (the one that covers the camera) is REALLY clean from both sides.
2) Accept the fact that in low light the phone won't shoot good pics.

The only time it will take good pictures is when the flash is right now the object, or if there is 100% sun on the object. As u can see on my example, there was fairly enough light but still came out Grainy.

Please explain more clearly!!
i have asked this before but looks like our phone does not come with sensors for this....
Maybe
This information could be invalid but AndroSensor does pick up a temperature sensor but not a battery temperature sensor on CyanogenMod 7. It could be a bug or an inaccurate component displacement for the ROM.

Basically, no apps can tell me my battery temperature. They all say 0°c. This is quite annoying for things like o/c and tethering, in case my battery overheats.

I've asked this many times and looked online some web sites say no
While others suggest the we have, magnetic sensor, heat sensor, and some other sensor that when I saw I didn't try pronounce.

Maybe the 'temperature sensor' is virtual and/or uncalibrated. The sensors available on CyanogenMod are for phones with a higher price range than the LG GT540.

On androsensor, on the temperature section, it says waiting for event, unlike your picture.

Did you wait for a while? It could also depend on the conditions of the ROM.

folks, this has also been answered a few times:
these "lines" are optical interference between the scanning frequency of the CCD and the frequency of some artificial light sources! other cam apps have the ability to enable a suppression for that (according to your grid frequency), the stock cam app of the note however does not have this function (or it has a very poor automatic for that)!
only chance: change the light-source or try to optimize your position!
OR: use a cam app which has a satisfying suppression function!
IF you have that lines also with no artificial light-source and in all cam apps then please take my apologies and replace your device!
Ahh.. I have the same thing on my work.. Guess the fluorescent lamps on the office interfere with my camera or something..
Nothing to worry about..
Found this thread on Reddit
http://www.reddit.com/r/LGG3/comments/2jmund/lg_g3_has_barometer_sensor/
Everywhere I read, I don't see any site listed LG G3 with barometer build in except a few comments in XDA stated it does have it. So I downloaded a Barometer app and sure it does display it! I have the D855 rooted w V10L.
To check for the reading if it's getting info from GPS location based data or using a real barometer sensor (found the info from another site somewhere):
Put the G3 in a large Ziploc bag sealed with the Barometer app running and presses on the bag to see if the sensor moves then it's a real sensor not GPS. And yes the sensor moves with the increasing pressure in the bag.
Okay, to make the test more convincing, I also have a brand new Sony Z3 Compact which has barometer listed in the spec and did the same thing in the bag along side the G3 and it's showing the same reading as I press on the bag.
So, unless I am not doing it right, I think LG or someone else never disclosed the barometer sensor being build-in in the spec sheet. Now this makes the G3 even cooler than it was before.
This is an easy test. Give it a try. Unless like the FM radio which is disabled for US version but not international version, maybe it is included in the D850 and D851? What is your take on this?

Barometer app seems to work! Very cool.
Now why would they put a barometer in and not mention it.
Now that the G3 has been found to have a pressure sensor this could be used also for an altimeter app...
Working, nice finding ...not sure what is it good for except of internal cooperation with GPS to faster calculate location.
Btw, nice application also with widget - https://play.google.com/store/apps/details?id=com.redTools.osb. Is has ability to correct measured pressure by actual altitude.
Can someone please provide an exact list of what typically is missing on Note 4 when you install a non-touchwiz rom?
Obviously samsung apps, but the ONLY samsung app I use is S-Health, and that can be installed on a non-touchwiz device.
What else? Fingerprint sensor? Stylus support? Heart rate monitor? Multi-Window? Humidity and Temperature sensors?
Thanks
You don't use the Samsung Dialler, Messaging, Contacts, S Planner, Camera etc. apps? Those are missing. Note 4 doesn't have any humidity or temperature sensors by the way. But I would also like to know whether S Health hardware sensors work on CM ROMs or not, as I use them on regular basis.
Special modes of Touchwiz camera cant be used

Honestly I have no frigging idea mate! The specs sure say that it lacks the Hygrometer the Note 3 had, but I will check that app myself! Samsung must be crazy to include it and then not mention it!
It didn't work at first in that app and then after an update it did. I think Samsung just used the same chip as the Galaxy s6 for that stuff and disabled in on the note 4 for god knows why. The developer of that app must have realized and found a way to link into them.
