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..

Why a magnetic sensor?

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?

The more sensors the better

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'.

Heart Rate Sensor

Hi!
I recently found an application called Runtastic Heart Rate In the Google play store.
It's almost like the S5 one but a little bit different because it uses the Camera and LED flash to measure your heart rate.
Here's a link to the app (free version) so you can try it out for your self!
https://play.google.com/store/apps/details?id=com.runtastic.android.heartrate.lite
And here's the paid version wich offers more features!

Does is work for real?

You got to be really naive just to think it measures your heart beats with the camera and LED flash...

Really try to read a little bit more before you say that.

these apps work BUT the distance between led and camera on S4 is big so there is no / little accuracy.
I used one of these apps with S2 and worked fine

Yes when I use it I get like 95% accuracy
If you don't believe me you can use the app to see what you get.
After that go into the clock app and click on the stopwatch tab then click start. Count your puls for 15 sec and multiply it by 4!
Then you see how accurate this app is.

Smartphones can already detect blood oxygenation if you put the finger over the camera and let the LED light shine through the finger. It's mostly used for pulse. I've tested this out, and it does work quite accurately most of the time.

G3 has Barometer sensor!

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?

Looks legit to me

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.
