Light sensor and screen protector question. - Galaxy Note 10.1 General

Hello,
I just bought a samsung note 10.1, and for now I just put on a makeshift screen protector which is covering both the camera and the light sensor. This is just until I can buy on to fit it. Anyway my question is, it seems like the auto brightness isn't working or working well. I have it on and the screen seems very dark, and I don't have the power settings on either. Would the screen protector covering the light sensor cause this?? or is there some other kind of issue?
Thanks all.

I can't recall how the auto brightness worked before I installed a screen protector so I can't comment on its direct impact but I wouldn't think it should matter. I do find th auto brightness a bit too dark in almost all situations and I think that is a Note 10.1 issue in general.
I just did some test in varying light conditions and the sensor was quick to respond and went quite bright when I was in a very bright room. I just think it over compensates in dark situations.

Thanks for the reply. I am sure it's ok, but it's been awhile since I had a android tab, so I wasn't sure.

One more question. Do you slide the slider for brightness all the way to the right then click on auto? I heard some say you put the slider all the way to the right, then click on the auto brightness, and that it wont clock lower then the max or something?

Display in direct sunlight conditions

Hi, i would to know the legibility of display in direct sunlight. Is it better of the Omnia display?! Or the same thing?

i would also like to know this as well. i believe touch HD has an ambient light sensor, but it is a different manufacture than that used in iphone. also, the HD's sensor is below two layers of plastic (the screen and the touch/pressure layer), whereas iphone's sensor is just below the glass. so those of you who already have the phone, please report back thanks

The HD's sensor is not underneath the screen/pressure layer. It is in the opening for the speaker. The screen is not transflective therefore the backlight is required to view the display.

okay. sooooooooo.... back to the OP's question : does the screen brightness changes when the ambient light changes? and it is good to view in direct sunlight? i couldn't extract the ansswer from your reply.

yes the screen brightness changes with ambient light. Display is comparable to the touch pro when viewing in daylight, but as the iphone is transflective, it will obviously not be as good.
Hi, I've had the Touch HD for 5 days now. The display sensitivity does change according to the ambient light, which I find very useful when going in and out of buildings. The display can be read fairly easy even on direct sunlight. I was reading an ebook without any problems midday with sun over my head. As far as Omnia, I can't judge since I haven't used one. But I can compare it to my old Tytn II which was unusable in direct sunlight. The display on Touch HD is really great.

OK...this is good.
The Touch HD display is not better than the Touch Diamond display in direct sunlight. Unfortunately it doesn't come close to the superb direct sunlight performance of the iPhone.
I also own the Sedna and although this device is perfectly usable in direct sunlight, even with the display brightness set to 0, the colors are dull and also much worse than on the iPhone under the same lighting conditions.
I can't hide the feeling that HTC just wants to earn easy money, look at the video performance of the Qualcomm chipset, it should have improved from the TyTN II outrage but nothing has happened yet.
HTC wants to build an iPhone killer? I'm pretty sure they can do it. Unfortunately they would need to charge much more for such a unit or at least lower their profit margin. Apparently they don't need to do that...yet.
actually it is not very good ... i cant see well...
any tweaks to make it peform better under sun??
yeah, i can hardly see anything on mine in sunlight, it would be ok to make a call, but to text or read a long text etc is verydifficult, didnt even trey watching a video, are there tweaks or anything for the screen?
disable auto backlight adjustment and crank up the backlight! battery peformance will suffer but its much easier to read. I think there are screen protectors out there than makes the screen more ligible in direct sunlight. try searching for it. dont take my word for it though
You can install Lumos and set it such that in sun conditions, it will respond with an increased backlight performance. At least Lumos will allow your phone to auto-adapt to the light conditions.
As for my personal experience, I have an ultraclear-type screen protector and the HD is pretty much unusable in direct sun light. I guess that with a less classy screen protector, the display would be readable outside but I haven't checked this out yet.
I tried disabling disabling auto adjust and cranking up brightness for sun.
It ATE my battery, left low level screen light on and this just is not a good thing.
I am outside a lot and looking for a solution, cannot believe the screen is so clear and good until you hit the sunlight. This is as I set on laptop and type in sun.

direct sun light

In Direct sun light my phone is really black.
Impossible to use it, I've to turn on the fast bright. The screen light auto calibrate seems not to function as well. Is there a way to Set the auto-light calibration values?
No, this is a characteristic of AMOLED screens, sadly.
What sun? There was no sun here since I got it
Use Anti-glare screen protector from Powersupport. They dont make the one for Nexus, but its so good that i fitted iPod Touch protector on my N1
It works when you turn brightness up, right? I can see mine just fine in the sun with full brightness.
I don't like auto-brightness. It shouldn't work well in the sun for any phone, considering it's trained to become brighter in low light situations and thus, dimmer in strong light situations.

Actually you got that the wrong way round.
In dimmer conditions the screen is also dimmer as less light is needed to see the screen.
In brighter conditions the backlight should be brighter to counteract the bright light.

Ha, thanks. It just seemed to have been getting brighter in low light situations for me so I turned it off.
I still think the screen is perfectly readable in the sunlight using the widget for full brightness. I'm surprised to hear so many complaints.
the complaint is about auto-brightness.
If I've it on and look at the phone in a sunny day it's very hard to find the widget to turn on the fast bright.
There's a way to set the values of auto-brightness? I mean to set bright at max when there's a lot of light?
my screen looks fine in the sun. I set my brightness to like 65%
If you move the widget to your homescreen it shouldn't be too hard to find in the sun.
It's the same Wobblebonk, sometimes when you light up you phone is not the home screen that appears you. In a sunny day the nexus screen appear totally black

try taking off your sun glasses :>
The home button returns you to the home screen... hence you can get back to the home screen regardless of what you can see.
the light sensor on my N1 is ****ed. maybe thats another issue......
try a soft reboot it helped with mine power +volume down +trackball resets without data wipe

n1 in a sunlight

This is a big concern of mine. I love the specs of the n1 but I've read that nothing can be seen on the screen in direct sunlight. I'd buy an HTC HD2 because I can even read books in sunlight with it but they stick with the win mobile and I like to have an android phone. So what do you say about n1 screen quality in comparison to the htc hd2 screen?

The only people who say this are people who don't know how to use the phone. Basically there is an automatic brightness option that changes the brightness based on how bright it is around the phone. Unfortunately, it seems like this feature always keeps the screen fairly dim, so I don't like it.
I have this feature disabled at all times and keep my phone at maximum brightness. It looks perfectly fine in sunlight.
People who say the screen doesn't work in sunlight don't know how to disable this feature (ie don't know how to use Android / change simple settings).

I've seen an app on an htc hd2 that changes the brightness automatically but one can adjust the brightness for specific surround conditions (i.e it looks like a graphical equalizer). I do not own the phone but I was told that this app works quite good. Is there something similar for the n1?
I can attest the screen pretty much sucks in sunligh at full brightness. The beaming sun in south florida is relentless.
Yeah, the N1 is hard to read in the bright sun and its not just pooping on stupid people that dont understand computerz or a simple setting that fixes it, it just gives glare in the sun.
Most phones/screens, regardless of their technology, are difficult to see in direct sunlight. But then, why are you trying to read the screen in direct sunlight? Just turn the other way, or shield it with your hand. Not that hard to figure out, really.
I use the automatic light sensor all the time. The only time is gets confused is is in a dim room, bright source (window, lamp) directly in front of the sensor. You have to realize what the sensor is seeing. Often times it's seeing light reflected off your face, hence the up/down/up/down of the screen brightness.
I honestly don't see either as issues with the phone, but the users rather.
I've had no problems using my Nexus One in direct sunlight.

really? i will be honest, i cannot see **** in direct sunlight unless i have the brightness all the way up... and that screen on full brightness is a battery hog...
I have no major probs with mine in direct sunlight, it's not that much different to the G1. I'm sure there are phones with better screens for direct sunlight but it's far from unusable.
The auto brightness feature works fine, you just have to wait a couple of seconds for it to adjust. Only people who don't know how to use the phone disable it and waste all their battery.

Really. I usually leave the screen set to auto, on the odd occasion I've had to turn it up to the brightest setting, but as the last poster said usually it'll catch up and turn the brightness up itself.

Or people who don't have any problem with the battery? With my use the battery lasts for 20+ hours, which is more than enough time for me to get to a charger again.
I always have the brightness at max and have had it that way for all the phones I've had (where you can set the brightness). If I'm gonna be more than a day without charging it I'll of course turn it down, but it's far from a neccesity for day to day use.
Just checked my phone and it's been off the charger for 16 hours and I still have 53% left on the battery.
Brightness in the direct Thai sunlight is fully adequate. The only problem I've had is that in direct sunlight, everything else is well lit, and so reflects off the screen.
Brightness: no problem
Reflection off the screen: annoying.

False. I know this phone well and disabled the auto brightness within 20 minutes of owning the phone. As much as I love my N1, and would not trade it for any phone, the amazing OMLED screen is one of the worst screens I've used as far as clarity in direct sunlight. This is not an N1 problem, but a problem with OLED screens in general. Assuming the new iPhone that should be released in June will have an OLED screen, it will have the same problem in direct sunlight.
You can buy anti-glare screen protectors that help this problem, but you do sacrifice some of the stunning brightness and clarity of the N1 screen in regular viewing conditions.
There is no way I would trade the N1 screen for the likes of the iPhone screen as the benefits of the OLED screen in non-direct sunlight viewing far outweighs the difficulty seeing the screen in direct sunlight. In fact, the N1 screen is probably its most impressive feature (aside from its blazing speed).

of cause this is the n1 problem and yours in the end! How are you suppose to take pictures with the n1 if you see nothing on the screen? How you suppose to dial a number if you see nothing on the screen? Saying this is not the phone to blame but the screen manufacturing process sounds stupid to me.
I have never in my life encountered an electronic device with a screen that was perfectly readable in direct sunlight, that is to say, as readable as indoors (not even my laptop plugged in the mains and set to full brightness). Reason: no screen technology can provide as much brightness as the sun. Solution: accept it, and cover the screen with one hand while you use the device with the other....

take pictures: look over the device and hit the shutter button..
input: open you jacket and form the number while providing shadow with it, or provide shadow with one hand while forming the number with the other. It's a fact that you need to accept, period.
Video sunlight test
Here is a video I found, it basically compares the N1's screen in sunlight to the Droid's screen at three different brightness levels. Enjoy.

note, since I'm new I can't post links... just remove the space
The screen is really nice in normal light but yeah it sucks in the sunlight LOL Probably depends where you live but in sunny South Florida it's a pain sometimes. Doesn't matter which direction you turn definitely have to shield it with your hand and it's still pretty hard to read. I'm looking into getting an anti glare screen protector for it to see how that helps. The display is absolutely beautiful but i'm starting to think maybe oled isn't the best technology for cell phone screens
Oled
The main difference between the screen technology in the N1 and most other phones is that on the N1, as I understand it, each pixel emits its own light (OLED = Organic Light Emitting Diode) as opposed to a 'liquid' film lighted from the back (LCD = Liquid Crystal Display). The only technology that I know of that will work well in direct sunlight is e-ink.
It is not likely that a pixel or a backlight could ever reasonably compete with direct sunlight, but on an LCD screen it is possible for the sunlight to reflect off the back layer or to hold the device is a certain angle to 'perhap's see the image better in sunlight then on the OLED type display.
However, having the N1 myself, I have found that I am able to shade the display in full Southern California Sunlight well enough to function with the device. The OLED display is much too gorgious to give up for LCD in my opinion.

Adaptive brightness issues

Is anyone having trouble with the adaptive brightness. I have it turned on and the brightness of the screen is not change regardless whether i'm in a fully lite room or in a dark room. I have it turned on in settings under display. Is there more too it? am I missing something?

No screen protector.. however I believe this is user error. I just read up on the difference between auto-brightness and adaptive brightness (which is on 5.1.1 and later). My device as functioning as expected.
The adaptive brightness on my device seems really sensitive, it even changes when the image on my TV changes from dark to light in a darkish room.
Agreed; mine is annoyingly sensitive, if I can say that. Very distracting while driving at night with the GPS on. Every minute it goes between bright and dark. Didn't have this on Nexus 6.

Yes. It happened to me while driving at night also. I hope that it will be tweaked and will be less sensitive.

No part of the phone protector covers anything on the screen-side, but are there ambient light sensors on the back, next to the camera?
I've got the issue too. Has anyone seen a solution like a kernel, xposed module or something?

Any way to increase brightness?

Samsung throttles the brightness when outside. It may save battery, but it makes the screen hard to see for my 50 years old eyes. On my other phone I can just turn up the brightness, but not on the Samsung. This means that I cant use my S10+ outside without reading glasses, so useless when out walking and the Samsung will have to stay at home.
Only help I have found, is an app called “High Brightness Mode”, but the difference is very small. And the Performance mode with 10% brightness increase, of course.
Anyone got a solution to this? Thanks.
Maybe you don't have auto brightness on because when it detects sunlight it bumps up the brightness a lot imo, or idk maybe you have either a defective unit or defective eyesight because mine gets plenty bright when outside.
I do have autobrightness on. But it only works in direct sunlight. If the sensor is in shade, the screen gets dim, even if all surroundings are lit by sunlight. Try moving your device in/out of sunlight and you will see, that it almost doubles the brightness when sensor sees the sun. That is the brightness I want access to.

Yeah, I don't think we can access that brightness level indoors (not manually anyways), and maybe it's because at those brightness levels (1000+ nits) the screen could suffer from premature burn. Probably that's why.

Should still be the choice of the owner, not Samsung. I dont think any other brand makes screens this dark... But thx for your input.
You need to make sure your display mode is Vivid and not natural. VIVID mode allows the phone to get sunlight readable when auto brightness is turned on. Hope that helps.

Have you actually tested this? I know this is a year later but natural boosts just like vivid, i dont see any reason why would it be different ever
Samsung let YouTube has the colorful mode but other app can't, this's rather very stupid
