Well the good thing is, I already got the Galaxy Note, yeah!
I have a couple of findings which I would like to get the
opinion on from other Galaxy Note users.
My packaging states "BLUE". But the device and back cover is all black?
Does anyone have a blue one, or know why it is called blue?
If I go under Settings / Display and try to calibarte the gyroscope
it seems that it does not work at all. The big calibration ball stays always in
the middle.
Also the setting for automatic brightness control seems not to work.
The display brightness does not change.
I also cross checked this with AndroSensor https://market.android.com/details?id=com.fivasim.androsensor
Which shows constant 10.0 lux for light sensor
and 0.00x readings for gyroscope. Strange
Can someone else verify whether this is a common issue, or
whether it is only my Note :-(
Btw. does anyone know how to verify whether the GNote can use Glonass?
I did a calibration and it moved around a bit and then stopped in the middle and said that it had completed.
As for screen brightness, if I put a tick in the box for 'Auto' it makes the screen quite a bit dimmer. Take the tick out of the box and I can adjust the brightness from dim to full without a problem.
So, sounds like you may have a dodgy one.
In terms of the light sensor. It is usuall that it dims when you activate automatic control.
The question is, does the brightness change automatically while you have it active.
E.g. Be in a bright room and turn off the light. The screen should light up. Turn the light on and the screen should dim again. Does yours do that?
Take your sim out of the phone or turn mobile data off and try to get a GPS signal on maps or navigation. Should tell you if Glonass is working. Someone already tested and said it works fine.

Why/How does that show that Glonass works?
My understanding is that it's supposed to be normal GPS and not AGPS. Navigation in most android phones needs data to be accurate. Not sure if that's the case with glonass. This explains glonass pretty well if anyone is unfamiliar with it.

I think you have that exactly backwards. In a dim room the screen should dull down so it doesn't blind you, and in a bright room it should brighten up so it's visible.

I just got done reading the specs, it says it has GPS withwith AGPS support. Sounds like a standard GPS.

Don't forget the Note (like the Galaxy Nexus) also has a 'Barometer' to aid GPS positional data.
As a Barometer also predicts height it will eliminate error margins for the Z-axis with GPS, which on other phones can be quite high.

Yes I wrote it backwards. And even more strange it suddenly works on Note.
Even though it is by far not as smooth line on a Xperia X8
In terms of GPS, I still dont know how to verify whether Glonass is used or not.
But I am getting 12 satelites used indoors and 16 outdoors. Plus on the box it states GPS/Glonass.
So I guess it uses Glonass. Which is bretty cool.
Remaining issue for me is gyroscope which seems not to work based on the calibration screen.
My findings with androsense and the light sensor are as follows
real bright light 1000 lux (right next to the light bulb)
normal room light 100 lux
dim room 10 lux
it seems that the current light sensor only has low medium and high settings. with no scaling in between.
i dont know if this is hardware or software related. someone else will have to give an answer on that, but it would make sense why a lot of other people are complaining about the auto dim working so badly. if someone could find a way to give the scaling a little higher resolution, it would prolly make the auto brightness work a lot better.
Mi also thought the ball not moving during calibration was a problem....but it works fine....i installed asphalt 6....went to the garage....the garage can be explored using the gyroscope.....
Install Asphalt 6....check it out....I think its not available for the note in the Market....but its available for free in Samsung Apps....its awesome...
hope this helps..

Hey guys,
do you think it's possible to wirte a program which automatically can change the backlight according to the actual daylight condition.
Maybe it is possible to start the program when you wake up your device. then the program turns on the built in (front) camera for about a second or maybe more. The camera "checks" out the light intensity. If its very bright the backlight condition is set to the max.
his is only a idea. I'm thinking of it because for example today it's a very sunny and i can almost read nothing on the display of my touch cruise!!
What do you think about it?
greetings
any idea?
Or does any software like this exist?
Maybe the guy who wrote this program below could be of assistance:
http://forum.xda-developers.com/showthread.php?t=379270
Well, it doesn't have to be so hard...
All we need is a small service that reads from a file the approximate sunrise-sunset time and alters the brightness accordingly. If anyone has the time, he can additionally take advantage of the current time zone and calculate those limits automatically all year long!
Destinator 7 does the exact same think by turning night colors on and off. It is actually better than a build in brightness sensor because it never fails!
Nevermind...did not read the question thououghly
Yeah good ideas,
but a time sceduled scenery has also disadvanteges. When its clowdy outside it causes unnecessary battery consumption.

I come from a rather sunny country (greece) so I really missed this!
Anyway, those PDAs have actually very low brightness screens. In a bright day you cant actually see anything. On the other hand, I have yet to see a rainy/cloudy day that requires a reduction to the maximum brightness level. Overall I think that a time scheduled solution should be the best solution for no sensor-equipped devices.

I second that! Even though I'm not from Greece but it's never too bright during the day. Right now my solution is to map the camera button to backlight so I can change it quickly.
Changing the brightness according to the time of day would not be as helpful as changing it according to the ambient light level. If you walk inside a dimly lit building during the day, you don't need the backlight to be as bright as if you were outside. Also, even outside, a cloudy day can be considerably dimmer than a sunny day.

I totally agree, but given the fact that there is no ambient light sensor in our devices I dont think that we can do any better. Two scales, one for day and one for night and we are OK for most cases. Yes, as you point out this strategy fails but it is better than:
1. No brightness change at all
2. Manual changes.

Thats the crux. Some devices especially the newer ones have a camera on the front. I'm no photo-expert but i think every camera is a "ambient light sensor".
The camera also reacts on different light conditions. You can see this by turning on the fps function. But i agree that it would be a lot of work.
Maybe we have to wait till more people and programmers own htcs with such bad displays like the polaris.
Titan Photo Sensor
I found myself thinking about this auto-backlight topic on my way home tonight after a long trip using my 8600 as a GPS. The screen went from being a clearly-visible screen during the day portion of the trip to a flashlight in my eyes at night. While I knew I could adjust the backlighting manually, I didn't want to mess with it while driving. Also, living in Arizona, I can barely make out the screen when in daylight unless the screen is on maximum brightness, but max brightness is horrible on battery life, so I would rather not set it to that by default.
Anyway, the Titan has a photo sensor on the keyboard which is used to determine dim lighting conditions and automatically illuminate the keyboard. I'm not sure if the exact lighting value being detected by the photo sensor can be read, but if it can be, then it should be relatively easy to write an application that would automatically adjust the backlight setting whenever the keyboard is slid open.
The application could both use location-based sunrise/sunset algorithms to set the default backlight value based on time of day, and also allow the setting to be overridden momentarily (perhaps only until the screen is turned off again) by opening the keyboard and sampling the ambient lighting conditions.
When I have my nexus one set to automatically adjust brightness, it doesn't seem to do anything.
I can move it between dark and bright environments and the screen brightness doesn't seem to change at all. Am I missing something or is this feature not working on my phone?
It works fine with mine. I just clicked auto in the brightness setting. Make sure you didn't accidentally change it to a different setting with the settings widget that is by default on the first home page to the right.
works fine on mine yet not a feature i use....i just set it statically.
I find the auto-brightness to be too dim for my liking. It would be great if you could adjust the overall brightness while still maintaining the automatic scaling.
Turns out it does work, it just need to be *really* bright to make it change.
It doesn't change really at all in my office between switching the lights on and off (even though that's a really big change in light levels to me). However, if i go outside, it does get brighter.
As you say though, it does seem to be set a bit low (hence it not brightening up when my office lights are turned on I guess).
If I enable auto-brightness on mine, it seems to constantly vary the brightness in my office. It's annoying as crap and I turned it off. Am I the only one?
It's probably taking a look at the available APIs to see if it's easy to write a quick app to do auto brightness with settings to be able to tweak it.
The auto-brightness feature changes constantly for me as well.
I 'm also having issues of the varying brightness when using auto-brightness -- even though the lighting in my environment has not changed and I avoid contact with the light sensor. It's VERY annoying.
I've since switched to using a static setting for the brightness.
auto brightness was one of the first things i turned off. it was way too dim for me
Not bright enough for me. Doesnt seem to change much.
I do see the variability occasionally. Most of the time it's stable, but it will take spells of shifting up and down repeatedly. Glad to know I'm not alone.
Auto bright annoyed me as well when I first got the phone. Then I realized where the sensor is (top left) and what it was responding to. Depending on where I'm sitting, what light sources are behind me, in front of me but reflecting off of me. It's usually just responding to a light source that's just withing view of its sensor. Also, my hand has shielded the sensor more than just a few times, confusing the sensor.
Now I leave auto bright on all the time, and it more often than not does a good job.
IMHO this is one of the few broken features on the phone. In continuous lighting it jumps from bright to dim to everything in between like a jack rabbit on speed. I still use it to save battery life but it pisses me off regularly.
am also having this problem. it constantly goes much brighter, and then, suddenly goes back to dim.. very annoying... however, the light sensor for calling works well... so, is it a software issue.. hope it gets google's attention and gets fixed in next update...

+1 so I also manually go between three on the widget
Note that the light sensor is under the glass on the front of the phone. Some cover-all cases cover this, and if you use one of these I assume your phone will remain on the dimmest setting.
In general, while indoors it will remain on the dimmest setting (for me anyway), but rise to the necessary full brightness when in sunlight.

There are two sensors, one is a light sensor and the other is a proximity sensor to detect when you've taken the phone from your ear. I think you're referring to the second.

+1 constant occiliation on dimmness levles under consistant light. It goes from way too dim, to just right then back dark again. I too hope that google will correct this with the next update. Hopefully the patch gets pushed soon, i'd like that extra memory
As far as the automatic backlight setting goes, it is my understanding that the phone should check how bright (or dark) it is, and adjust the display brightness accordingly (brighter when out in the sun, darker when sitting indoors / dark rooms).
However, it seems to me it just sets the backlight at ~40% and that's it. I went out into the sun with my HD2, and the brightness didn't change and I had trouble seeing what was on the screen.
Is there some kind of way I could test, if the light sensor is working? Or is this setting simply badly designed and I should set the brightness myself?
I'm currently running latest Energy ROM (23569 Cookie May 09) but it was the same with the stock ROM, so I don't think it's related.
PS. A little side question, if I may; if I perform task 29 before flashing... do I still need to do a hard reset after flashing a new ROM?
...in the very least... are there any apps that make use of the light sensor?
Well I know the acctualy percentage in the settings never changes when its on auto (atleast not for me)
But I can clearly tell a difference between being in a dark room and the backlight being on low
to being in the sun and it on max.
Ive also never had trouble reading the screen, the screen is always plenty bright enough.
Prehaps you've got a bad one?

Care to share the name of that app?
Also, it's difficult for me to say if the screen is busted or not. On max brightness (as opposed to the automatic setting) it's a lot more comfortable to look at in the sun, albeit indoors it's OK on any setting really.
EDIT: I don't suppose the automatic setting can be tweaked for better performance via some registry changes?

I think it's called Lumos.
Try searching for it.
You certainly can test it. Just cover the light sensor (upper left corner above the screen) with something. I don't recommend thumb, as you might press 'start' button. You will also need any application with white background.
The brightness should clearly drop.
Auto only sets the brightness from 20% to 60% (or so it seems). But the effect is clearly visible.

No change at all.
I'll restore the stock ROM to see if it's a firmware issue, and I'll check that Lumos application.
EDIT: Lumos clearly detects light changes and works well. Seems it's either something to do with Energy ROM after all or possibly I'm just blind and I can't see any changes. I'm still going to check the stock ROM, just to be safe.
BTW, once more, can someone tell me quickly if hard resets are needed after task 29?
EDIT 2: OK, it DOES work after all, I'm just blind; the change however, on the automatic settings, is minimal. I actually had to put the phone under a light-bulb, as covering the sensor didn't really work. I wonder if it should be calibrated like the g-sensor...
night time
i think the day time brightness is fine but the night time setting is far to bright. i would love for this to be customizable as well

For indoor use the auto-adjust works fine for day/evening/night, but outside I always need to turn off the auto-adjust, so it can go to 100%. When back indoor again, then switch to auto again and so on ... and so on ... and ...

Hi, My T-Mobile DVP's auto brightness doesn't work after i upgrade it to mango. It worked in pre-mango, if i cover the light sensor or light it up, the screen brightness would be changed. But it isn't like that in mango (version 7720), no matter i do, it is always at the lowest brightness level. The light sensor still works well in EM, it can detect lux value so i think this is a faulty OS firmware.
So after upgrading to mango i lost two sensors: compass and light sensor (Well, compass still worked in EM in pre-mango but in mango it doesn't work, even in EM). I lost my faith in Dell, too . My Dell laptop dead one month after end of its warranty and cannot be repaired, now this one ...
Anyone have the same problem ?

Hmm its not instant and it takes 5-6 seconds to adjust, because the light sensor is working fine in the EM app it means its working fine with the phone, also covering with hand doesn't work. Try putting it under a couch then put it by a windows on a sunny day.

Anyone who has upgraded to 8107, do you have this problem ? If the problem is fixed in 8107 i'll think about upgrading it manually
Try this: Turn off auto brightness, change the brightness from low to either medium or high, then turn auto brightness back on.
For some reason the brightness setting (that is inaccessible when autobrightness is on) functions as a limit when autobrightness is on. If it's set to low then autobrightness will never raise the brightness above low. Set it to high and try it again.

Good finding ! It worked ! But there is another problem . That is when i light up the sensor, it bring the screen brightness to the highest level, but it suck in that level even when i cover the sensor. I waited 2 minutes but it just didn't change, it was always on the highest level. Then after i locked/unlocked, it turned back to the lowest level.
So auto-brightness is not a completely unusable like compass, it's just too faulty to be able to use
Hello everyone ... Can someone help me please... I have my s5 for a few days ... And now I saw that my proximity sensor Is always on, I can see the red light even if my phone is locked... And I'm worried that is using my battery I got 5 or 6 h display max with 1 day of usage
Proximity sensor doesn't utilize a red light. Maybe you have a malfunctioning notification light?
Notification light is on the left. Proximity and light sensors are on the right.

This is not a concern. The proximity sensor is an infra red sensor and emits a faint amount of visible red light. All of the S5's do that, it's normal and it is no barrier to great battery life.
If you did a forum search you would find existing threads where this has been asked and answered before. The glow probably represents the average bias current as the sensor periodically polls it's environment every x ms. In any event it's normal and expected behaviour.

After a fresh reboot, there may not be any apps using the proximity sensor. But a lot of apps do make use of it, so as soon as you use an app that does, the sensor will start monitoring and there will be that glow.
I don't think that the sensor uses much battery in most apps as mine is usually on. Even my screensaver makes use of the sensor and I still get great battery life.
