ambience light sensing & portrait/landscape sensing through the front camera? - Tilt, TyTN II, MDA Vario III General

Dear all,
I have an idea to share with all my fellow Kaiser user. Since we have a camera, why don't we make use of it to check the ambience light and auto adjust the backlight according to the level of brightness sensed by the camera. Also, using the front camera, it should not be hard to check the orientation of the ppc, it would be nice if PIE or and browser adjust itself like the iphone did.
Just my 0.02. Hope this idea can help.

your idea is good, but has some "design flaws":
1. the camera adjusts the overall brightness automatically, so if this can't be disabled, it would be useless.
2. if you would point the camera at a white wall or a black something you would get different overall luminance, even if the ambient light is the same. again, useless.

Is there another parameter which is detectable which could allow for such a problem?
Dunno how to program at all, just thinking...
...what a bunch of tightarses these companies are not using a transflective screen.

the camera autoadjusts brightness for the picture you are taking, not for what it actually receives...
This application does exist for the PalmOS (caled BrightCam) and works beautifully. I truly miss this app on my Kaiser now. I wil inquire with the developer if he has plans on anyting for WM.

Camera Driver yet?

I was wondering if there was any sort of camera driver for download yet, ive been looking all over the site and have yet to find one, and ive looked throughout the internet for one, but Im finding old websites not updated since january....pleeease anybody?
Is this what you are looking for?
http://forum.xda-developers.com/showthread.php?t=355587&highlight=camera
that version is still slow videorendering...
Thanks, it seemed to help out alot in brighter areas but the dark places are still slow... its no problem to me ill just use a dig camera if I need a dark pic... thank you =D
A trick I picked up here with the "new" driver was to turn the camera on. After it comes up, press the power button to put the phone in "sleep" mode. Hold your hand over the camera lens, wake up the phone with the power button, wait 5 seconds and see if the frame rate is a little faster. Goofy trick, but it seems to work.

i found this trick a long while ago. it does seem to work but i dont think it has anything to do with the htc-ca or omnia drivers so even if you dont have them installed, it will work.
I'm using the Laurentius26 V10 ( http://forum.xda-developers.com/showthread.php?t=416278 ) cooked ROM with the HTCA drivers ( see http://www.htcclassaction.org ) and the camera is performing extremely well. There is no evidence of any lag when there is sufficient light available, it seems to still take a performance hit when it has to compensate.
Rob
ps. that trick that p51d007 suggested is completely bizarre! Even the lag with close up or darkness goes away.
i am using the hyperdragon iiir lite rom with the (recomended) radio 1.65.24.36
and the omnia 3d driver installed in it
and video acceleration is perfect!!
a small improovement i have see also in camera
From my point of view... the camera gets SLOW whenever it has to increase exposure to compensate for the dark areas. The power button somehow fixes te exposure... or disables it.
Point is.. although being 3.0 MP...camera quality is nothing like a 3.0 real photographic camera. So... my question is...
Would picture quality get that worse... if the camera would always shoot with a fixed (lets say 1.0) exposure... and then increase the brightness of the picture via software ?
And to be REALLY bold... and please realize that i'm sugesting with virtually or really NO KNOWLEDGE ... 3D graphics can have its gamma controled... at least in a normal computer... how about showing the camera image on a D3D or OGLES texture... and increasing it "exposure" via gamma control ?
(Am i nuts?)
Yeah that trick works, but the picture is darker and a lot grainier. Also if you point the camera to a bright light source, it "resets" and then when you point at dark areas again, it lags. That trick seems to "initalize" the camera to a dark setting, for lack of a better phrase.

Damn, you're right, it resets when you point it at a bright source...I was all excited for a minute, too...
I wonder if there is a way to make the camera behave that way all the time? I snapped a picture with the trick active and it came out pretty good.

Dim brightness + Mic sensibility + other infos

Hi there!
I am a new user, and I've got some questions:
1) Is there any way to change dimmed mode brightness live from the watch?
2) Is it normal that alarms don't work during Theater mode?
3) Is there any way to reduce microphone sensibility? I find it pretty unusable when in my car because of the ambient noise (it just keeps listening as there are other sounds)
Thank you very much in advance!
Hi, let's se what i can help u with
1) From the watch you can download the swapps true dark or something like that which is a kind of screen filter reducing the brightness on both dimmed and live mode.
2)yeah, that's how its supposed to work
3) mmmh same thing here, since we use it on the wrist which normally is used to drive the car xD idk of anything to reduce the sensibility, hope someone here comes out with a solution

1) I've found the app, it works, but still have to figure out HOW does it work :silly:
I don't understand what the light bulb stands for and why it becomes full or empty when I choose the settings (I suppose that the bulb "on" means the higher lvl of brightness, bulb "off" the lower one, but can't really understand how to set this properly - but it works somehow, so this doesn't matter too much)
2) Ok
3) I think this is something kernel/rom related, some value to change, like the vibration one (by the way I MUST apply the vibration mod, because I don't wake up with the normal intensity)
Thank you again for your help!

You're welcome!
In swapps the bulb should work the exact opposite way you guessed xD i mean full bulb means the "dark mod" is on so you should see the screen darker (select the intensity of this "dark filter" below on the grey-scale thingy, on watch app). When you tap on the bulb it becomes empty and the filter is deactivated so your screen turns back into default brightness.

Auto brightness working well for you guys?

I noticed that on my S10e, auto brightness doesnt work as well as it did on my Note 9.
Sometimes I have to manually turn down my brightness if I turn off the lights in my bedroom for example. Or if i turn on the lights, brightness stays on the same level. But if i turn off my phone display then turn it back on, the brightness is suddenly changed.
How well does it work for you guys?

I have noticed that my S10e is slow to respond to ambient lighting
I have an S10 and to be honest it's hard to say if auto brightness is working how it should. Coming from an LG V30 this phone's display is significantly brighter and especially more apparent when using it in the dark. Even the darkest setting is too bright. I always check the level to make sure auto brightness is working as it should and I guess it is? Either that or it's stuck.
my only comment is that in totally dark room it does not go all the way down , it stays a little bit brighter than normal and than my old iphone x
talking about the s10+

yeah same here, and the strange thing is that on my Samsung Note 9 & Samsung S7 it actually used to go all the way down in a totally dark room, but on this phone it doesnt for some reason..
It can take a bit for Adaptive brightness to learn what your favorite settings are like.
Yes, same here, I have s10 and in the dark auto brightness is near to half. Wtf?! I tried to calibrate, no chance. For sure this is a bug. If you go in *#0*# you will see it s writing uncalibrate light sensor

nah, on my Note 9 & S7 it worked as it should on the first day i got those phones
there clearly is a problem with adaptive brightness on the S10, anyone with the S10 who had another samsung phone previously will notice that
no, the auto brightness is trash. it sucks. it never gets bright enough even tho i've made adjustments literally daily. it sucks.

Even with factory reset it still happened.

First reason: I want some T-Mobile features what unlocked doesn't provide natively and may require an extra app to function, but if before return window closes, I would be able to find a 100% firmware that would work, then I may not return the device.
Second reason: I don't like the fingerprint on S10e and maybe it is somehow better than S10's implementation, I still have to be more precise than Pixel 2 and other which had the sensor on the back.

Oh, that is not convenient at all. I think the manufacturers are pushing their limits to please customers with new designs/features which in reality hurt the quality of the devices we pay for
I have the S10 plus and the auto brightness seems to be functioning fine. Occasionally in the dark I get thrown off with how bright this screen is. The brightness setting does decrease significantly in the dark but when viewing something with a mostly white background, I have to squint until my pupils constrict to a point where my retinas aren't getting torched. In brighter environments, the brightness level seems to increase accordingly.
Hi guys,

Facing Issues With Galaxy S10 Auto Brightness? Do This

Galaxy S10 auto brightness

We have already covered the issues with the proximity sensor in the Samsung Galaxy S10. Now, it appears, one more sensor in the Galaxy S10 is not working as it should. Several users are complaining that the Galaxy S10 auto brightness or the ambient light sensor is not working perfectly.
Galaxy S10 auto brightness – what’s the issue?
Affected users have raised the issue on social platforms and Samsung’s product forums (first spotted by tech site PiunikaWeb). Users complained that the brightness level does not automatically come down in low light. So, they have had to do it manually, but it remains at the set level even when the light is good.
“Sometimes I have to manually turn down my brightness if I turn off the lights in my bedroom for example. Or if i turn on the lights, brightness stays on the same level. But if i turn off my phone display then turn it back on, the brightness is suddenly changed,” one user said.
Further, users also say that with adaptive brightness turned on, the screen goes dark when facing the sun. “White highlights are bright blue, and all colors are distorted. It’s unusable. Spin back around or go into the shade, and the screen comes back to normal,” one user said on Reddit.
Users say that this was not the case with the Galaxy S9, where the auto brightness feature worked perfectly. One user even claims that the Galaxy S10 doesn’t even have a light sensor, instead, maybe there is some in-display sensor that needs a software fix.
“..even if you put your finger on the front camera the auto brightness still moves …..also if you acces this *#0*# you cannot find the light sensor because it’s not there like old samsung phones,” one user said on Samsung’s product forum.
Adaptive brightness to blame
Several users believe that the adaptive brightness is to blame here, and so they have turned it off. However, turning it off is not a solution, and many users agree to that.
“This is a huge problem, and should not be happening on a new phone. The adaptive brightness is a major feature of the phone, and simply turning it off isn’t an option as far as I’m concerned,” one Reddit user said.
It must be noted that Adaptive Brightness came with Android 9. It is an AI based feature that gets better with time. Meaning, it would learn from the interactions that users make with the screen brightness slider, and over time, it would customize the brightness automatically to meet the users’ needs.
Google says that in its testing for Adaptive Brightness, it found that half the test users made fewer adjustments to the slider after a week of using the Adaptive Brightness.
Not an issue, give it some time
Based on Google’s explanation, it seems, users need to give some more time for their phones to adapt to the Adaptive Brightness. Even Samsung’s explanation of the issue with the Galaxy S10 auto brightness is somewhat similar.
“From Android P, a user’s brightness setting pattern is learned, and when the user sets a specific brightness the automatic brightness is controlled to be closer to that specific brightness…… However, when you set the brightness, the brightness can be applied immediately in the short term. If more than 30 seconds after the screen is turned off and the ambient light environment changes by more than 60%, this short term setting brightness will return to the light that was relearned,” Samsung developers say.
Additionally, developers say that users can reset the brightness curve to start the learning process again. To do this, go to Settings – Apps – Show system apps – Device Health Service – Storage – Manage Storage – reset Adaptive Brightness.
All this explanation from Samsung developers and Google could mean that the complaints from users about the Galaxy S10 auto brightness are valid, but it still is not an issue. Things will get better with time as AI learns more about users’ preferences.
Though it is not a bug, affected users do not seem very satisfied as they still have to live with inferior quality images (even if for some time until AI applies the learning).
“Not sure it’s a error to be replicated per se. It’s just an inferior looking quality of image. They will have to make the comparison to see the very obvious difference,” one user said.

FYI : the brightness sensor is under the screen like the proxity sensor, located bellow the wifi / network icon. It's visible at sun light.

There are actually two light sensors: front and back of the phone.
Unlock the device without pressing the power button and only by placing your fingerprint on the sensor.
The light sensor starts checking the environment light only in this situation

Max brightness bugged, help me pls

I am experiencing automatic dimming of my screen when set to maximum. The big thing is Adaptative Brightness is Off. I also set Power Mode to High Performance to make sure power management would not dim. I even bought an app that supposedly cranck up brightness beyond system limits (did not work)
I first noticed this when taking pictures of my garden in bright daylight, the screen was dim and even going over the orange marker on the dial I still struggled to view the screen (sun was almost 90 degree angle).
However when I placed my hand over the screen I could see well but then I noticed a sensible dim. At first I thought it was some king of optical trick, so I tried to repeat the experiment in different conditions to the point that I would simply crank up brightness and have a strong light over my phone then I used a black sheet of paper just above sensors. If I take the sheet off the brightness ramp up a bit, if I put the sheet over the screen dims. And again no auto Adaptative Brightness is turned on neither Power Mode in save.
I guess this wasn't supposed to happen, if I want to ramp up brightness as much as I want I should be allowed and the system should not interfere with my preference? I don't need to justify my use to anyone but as a courtesy to those that are inclined to help me, here it is: I work a lot with gardening and construction all day, including strong daylight, and I need to take a lot of pictures for my work.
What can I do to squeeze this bit more brightness from my Note 9?
Thanks a lot.

Tint in k20 pro display

Hey guys, hope you are doing great.
I have noticed one peculiar thing, when i sit in pitch dark places with brightness at the end, i face this white issue over my display screen shot attached, it's Google chrome app which showing me these results,(there are many more also)for this to be noticed you must sit in a dark room.
I know it's typical led panel issue and i would like to know if i am the only one?
Do you seriously think we are able to see your display in a screenshot?

If you are in a pitch dark room and see no anamoly then your's display is good. If not you will see a whitish tint over the top area
And btw you can check on your device itself, by just opening chrome(if it's black) and in dark room with brightness as low as possible.

Enable feature in display settings under anti flicker mode to on. and check again your screen in low light conditions.
Yup, that worked, it increase overall contrast for low brightness, is this condition(tint) is normal for amoled panel, or i am just unlucky.
