Hey Guys,
got my new Note II yesterday, but already having 2 problems.
The biggest is the light sensor; the Screen keeps adjusting it's Brightness like hell.
Read out the Sensor data, which is going from 0 to 13 lux when I cover the Sensor with my hand.
Do you experience the same?
Also my USB wire plug is very loose. Also normal?
try turning off auto brightness...
and yes USB wire IS a bit loose

Well, just bought it brand new, I think this shouldn't be on a 600€ device
Does your Light Sensor Value also jump around in same light conditions?
Low-Light mine goes from 0-28, normal it goes from 400~ to 80.000 sometimes, which results in frequent readjustment in brightness.
Thats very irritating for me, cause I use it everytime
Would be nice if someone could give me his values/behavior of the sensor with AndroSensor or so.
Will return this device then

I just got my GT-N7100 and am having the same problems. Very irritating. Need this to work for better battery life. Tried a program from Play Store called Lux, but it works the same, maybe a little better. But Lux is showing the sensor readings varying all the time even when the ambient light hasn't changed at all, thus the brightness fluctuations. I am rooted, but on Stock ROM. Wonder if a custom ROM would fix it, or if it's a defective sensor.
Anyone else experiencing this?

The default auto-brightness should not be updating so fast that it flickers You might want to get it checked out. Or if you use a 3rd party app, reduce the time interval of the update.
And do note, there is a difference say, with your back towards the sun, you face the phone towards you, or towards the floor. So when you are on the move, expect values to change.
Stock auto brightness is woeful in my opinion. It was the same one my Gnex so I have used Luxbon both with good results. Takes a bit of tweaking but brilliant when set up.

I'm not an expert at light sensors, but look at this:

I'm moving phone, holding camera still.
It looks like light sensor problem on galaxy note 2.
Can you check yours GN2?
Use code *#0*# and enter sensor test.

I'm not in the brightest room but I have 2 60W light bulbs above me and my sensor has 0 when the phone is towards me and 20 lux when it is towards the roof. And yes it's stable with the values.
Whoa, I didn't know our phones did this. How cool!
Yeah it definitely has it, but it's not advertised because of how woefully inaccurate it actually is.
Didn't know that either, thanks!
Actually mine works fine. Temperature is withing 1 degree as long as I don't use my phone much, so it doesn't heat up skewing the results, barometer also seems fine, the couple times I checked at airports or from weather channel and adjusting for altitude, it was within couple mbars. At least with barometer, you can adjust it to correct value, if the error is big, where with temperature the main issue would be to keep the phone at ambient, so don't get surprised at error if you kept it in your pocket, or played game. There is also humidity sensor and I was shocked when it showed 100% humidity on a foggy evening, as it should, so that seems to be working fine as well.
I haven't had similar experiences with mine, although perhaps not using the phone could provide slightly more accurate readings. I live in a pretty humid area and have found even on the most humid of days it doesn't register properly.
You must have newer hardware -- I don't think either my 900T or 900V have humidity and air pressure sensors.

I found a sweet app called Thermometer Plus. The reason I like it is mainly the selection of semi-transparent widgets (displaying different sensors). I have the one with temp and humidity (set to update every 5 mins I think) on my main home screen so I use that to adjust my AC, etc. accordingly, mainly to keep humidity in a reasonable range.
Galaxy Sensors is also cool to see all of the device's sensors. It also has a widget, but it only displays the temp.

I bought mine in November so it's not that new, I think all N3 have it, but they don't show normally.
If you check Antutu benchmark under hardware, it should show all sensors.
Androsensor program will show all sensors readings, or type *#0*# on stock dialer, then click sensor, should show all the hardware and if it's working.
Pete is correct, all variants have it.
Guys, please help . SM211 became randomly shut down . During charging and standby time is working properly , and during the active battery life it off. CPU-Z shows CPU temperature is constantly 80 °, but the body is cold. Tried different kernel and firmware , the result is the same. What could be the problem ?

Greetings aosaid, It sounds like battery problem. Can you tell me which part of the device is heating up?
If you look at the screen , the left side a little heated when I play , it has always been . The battery temperature is normal. Now charging, temperature is 29°.
I did calibrate the battery . The charge keeps well .
If you are rooted, you can download cpu control app to decrease the cpu frequency. See if its working.
Yes, rooted. I limited the CPU frequency up to 1 GHz, it has not helped
Try the following link:

Thanks for the info. But it does not help. The fact that any program displays temperature of processor 80°, always, it is not changed. No matter what I play or tablet is just lying on the table with a minimum of running applications. Even when during the game heats processor that is felt on the case, cpu temperature shows 80 °. It seems that the temperature sensor is not working properly. And the battery is always normal temperature, and shows adequate. I'm not sure that the temperature does matter at all. Yesterday the whole evening I run different applications, played a lot, the tablet never turned off. I want to check there is a dependence on the Connect to the network, wi-fi or 3G.
sounds right, sometime sensor might fail.
Forget about the temperature . I noticed exactly convinced that it is switched off only when I use the data transfer via 3G. When I connected to wi-fi, everything works fine and without chrarging.
sorry for my English, I'm ukrainian
Alright then,
So, nobody can't help?

I have a theory but idk if its proven. If the device got heat up and the sensor tell the system to force shutdown to prevent further damage. Thats what i have thought of. I think if you can get a new battery and see if it works.
still, I carried the phone for repair. the problem was in the connector on the battery. only. repair cost the $ 5. I thank you for your help

haha so i was right about the battery part. congratz ffor ur problem fixed
Who would have thought that such a small thing can become a big problem.

True haha
I have been looking into ways to increase signal and have found to promising settings one is antenna diversity as i find that transmit power is the limiting factor especially on b41 as my rsrp is better then iPhone 6 plus and note 4 from what i have found using diversity can reduce tx power 5 to 10 db as the secondary absorbs radiated signal and it coincidentally had been shown b41 is weakest and also that is the band that has much better rsrp than my other phones fcc limits to 23 db which is hit while rsrp is close to 100 which is very usable
Also i found a setting that reads sar sensor and had settings 0 through 8 we default on 0 Samsung is known for having very low sar output and increasing frequency usually increases tx output and once again coincidentally iPhone 6 plus was measured 31 db on band 41 extremely higher than any other phone and most hot spots and also is 1.59 on sar output once again higher than any other phone if anyone had any input would be greatly appreciated
longest. sentence. ever... Please use the key on your keyboard two spaces over from the "M" key.
Now as for your findings, certainly interesting. What are the settings available for antenna diversity? Are you able to choose between switched and combined?
Lastly, where did you find the setting for SAR configuration?
Their is both,primary, secondary, and diversity
Settings for sar is
Test mode
Ue setting and info
Settings
System
You have the option to disable the sar limiting.
I have searched high and low and their really seems to be no information on this however i do recall on my Nokia 3390 their was a code that was able to increase tx power i do know that the modem has to have different power levels if they are set in some low level way i don't know but different phones have different antenna gains so would have to have different power levels especially since mdm 9635 is used in broadband cards/hot spots as well which are allowed higher tx power
Sar back off is real their are articles about it on ipad
I have no idea whats going on in this thread.
It is referring to a sensor in our phones that when you are holding it in hand or get close enough lowers broadcast power by up to 25 percent to reduce radiation from phone

Not at all quite the opposite i worrying about trying to disable it to increase network performance
Well further investigation i found that qpst can access calibration of radio wondering if can increase transmit power
Ive searched all over, how are you getting into the settings to make these changes? or is this just theoretical?
None of the dialer codes get into the menus I think youre suggesting work any more, and I cant find any way to unlock them...
Im scared and confused
I'd be nice to get than one bar for a change. Way too often does my signal go kaput.
I disabled sar backoff in the secret menu, would this make radiation dangerous when using phone to make calls near ear/head? Also, what is best setting for the sar state from 0 to 8, and do those values matter if sar backoff is disabled?
Where is this setting?
I think you just have to keep backing it down until you reach a setting where your ear glows, then go back up one
Also; if you believe the numerous studies stating that non-ionizing radiation isnt harmful, then all settings are safe.
go to phones settings menu - activate this device - more->PST - TestMode Menu

I only did a little testing but I didn't see a difference between 0 and 8
Try testing the sar backoff flag setting too to see if it makes a difference

Dialer codes are only for carrier and manufacturer menu settings regarding to activation/device stats.
The things the OP is referring to is a level deeper, something you can't modify from a menu. It involves connecting the phone to the computer and changing values in codes pre-set for the phone's processor and sensors.
QPST is a Qualcomm tool. This stuff all delves into a different world than most deal with here at XDA, because most of the time if you are using QPST you are trying to flash a new carrier on your device, manually update or add a PRL that isnt "approved" by the carrier, or reprogram/ Clone/ fake/ spoof/ etc which gets into an even deeper world that is against the rules here, because its a slippery slope leading to illegal stuff.
So thats your answer in a nutshell. You wont find alot here about that stuff for the reasons above.
I wonder how much extra radiation is emitted with sar sensor disabled.
As title, the gt2 received a update that add the sp02 now, but it has a sensor or is only a software sp02?
if not.. maybe in amazfit products is possible to add is by software
The hardware is there anyway just locked previously, so I see no reason to trick us with software...Saying that, I don't have enough medical knowledge to verify the readings, though it seems reasonable

it's a sensor I am pretty sure. If you turn it on you will see one of the light sources (red) turns on to measure a delta through the skin. I recently went to the doc and the nurse was nice enough to measure my SPO2 level twice with a finger clip on device and the watch was within +-2 of that measurement. I'm pretty impressed.
