outdoor backlight increase

Htc Hd2 has only one flaw: outdoor display contrast. in the bright day contrast is not on the iphone display level.... if there is a possibility to increase display light and contrast?? i try lumos but result is same as before... I dont want to use antireflect foil or anything similar ....

I suppose that's very subjective. I use lumos with my own settings for the brightness curve (linear with a deep slope) and I can use it in daylight with no big issues.
In case you wanted to test, you probably could set the screen brightness to 100% manually from manila preferences to see if that suits your need, and then agjust lumos curve to your needs

I try again with lumos .... probably something I was not well set up ...

hey! -------> this time it's better and brighter!

But isn't the auto-backlight feature doing the same thing? Making Backlight bright when outdoors?
How is it compared to lumos?

Lumos gives you control over the backlight. You can set up minimum and maximum backlight as well as the backlight intensity curve (vs external light intensity).

The built in auto backlight feature is very weak. It is fine for indoor use but it does not seem to get any darker in the pitch black and does not get much brighter in direct sunlight.
I find myself manually adjusting it everytime...

Agree - the automatic backlight is not working sufficiently. You all need to log this with HTC customer support so they can add it to the next firmware release. Issues really need to be logged sooner rather than later as this phone is going to soon be too old to warrant HTC spending any more time fixing things.

I've been trying to report everything I can before windows 7 comes out and everyone forgets about the Leo.

Hm, well I recognized that the Auto-Backlight is sometimes "slow". But not always. If I walk from a bright room into a dark room the display gets darker. But sometimes it stays quite bright.
Perhaps I give lumos a try. At least to compare.
But when Lumos has so many options to set a brightnes curve, won't you find yourself setting up an adjusted brighnness curve everytime because there is no curve that fits to every situation?
Sometimes there is bright sunlight and shadowy corners, sometimes there is a thunder-storm and barely light.
The light gradient won't be a linear one .

Ok, I played around a little bit.
What are your Max values with HD2? 1178 at mine.
0 is Min value but thats clear. Only thing that is wierd: When I move to a place not directly near a lightbulb the sensor goes very fast down to zero.
It shows zero but it is not dark in the room at all.
Is it the same at yours?

My screen is too bright, what will make it dim below "10"?

Even on the dimmest settings, the Vibrant is too bright for me in bed, where the light disturbs my wife.
It seems that, with root, you can lower the brightness further - at least on other phones. Is there any way to do this with the Vibrant?
Thanks!

The "Dimmer" app will toggle it from your current brightness down to 10 but if you find something that will go lower let me know.

It has an automatic brightness control based on input from the sensor. You may need to disable this in the settings too, but I would think it would be automatically dimming itself already in a dark room.

Right, but that doesn't get dim enough in some situations and the minimum brightness you can select manually is 30. "Dimmer" will take it all the way to 10 but I would like to see something that would take it to 1 or 2.

I agree. It's too bright in low light situations.
If you find a solution please post it.

Try the Screen Filter App from the market. You can get UNBELIEVABLY low brightness. Which means much better battery.

+1 on screen filter. New version now dims taskbar too.

[Q] Auto-brightness Sensor

I am currently running JPA/JPB Hybrid firmware and I was wondering if there even is a sensor for the auto-brightness.
Normaly I have set my brightness to the lowest level, which is enough for indoor usage. But as soon as I am outdoors in the sunlight I can't even tell if the display is on or off with this brightness level.
Now the strange thing about this is that it does not seem to make a difference whether you check the "Power saving mode" in the Display settings or not - the Display brightness always stays the same:
- with the highest level it does not get darker in very dark rooms to save battery
- with the lowest level it does not get brighter even in direct sunlight, which makes the display unusable
On the left of the Samsung-logo there are 2 "holes", I guess one must be the proximity sensor and the other one the brightness sensor?
Is there any way to have the brightness on a very low level in dark rooms and on a high level in bright rooms / outdoor WITHOUT switching manually? Even switching with a widget sucks, because outdoors the display is so dark that I can't even draw the pattern to unlock the screen first (at least not without covering the display from the sunlight)

If there is I think the driver is missing so it's useless.

There is a brigness sensor, not for auto adjusting the screen brighness, for example try *#0*# and press sensor, now if you put you finger on the sensor, you phone vibrates, it means it is dark, if your finger is not on the sensor, it says, its brighten outside, that is for example to telephone, the screen goes dark, when you put the phone to your ears

"that is for example to telephone, the screen goes dark, when you put the phone to your ears"
No, that's the proximity sensor, and I think there is no light sensor in SG3, because that test app shows only proximity, accelerometer and magnetic sensor.

Power Saving is not for dynamically change the strenght of backlight. It's just turning to lowest level when your battery is 15% and less.
And there is 2 holes, for proximity sensor. Try to cover one hole, and it doesn't work. Why? Because 1 hole sending an infrared (I think...) wave, and second is receiving that back, from eg., your hand.

totaly makes sense - thank you very much!

Auto brightness only brightens, never dims

I noticed that the brightness only brightens but never dims back in automatic brightness display setting. I can reproduce this easy with turning the lamp on my desk on and off. It only goes back to the lower brightness if turning the screen off and on again.

Noticed this too but seems to only occur when I use a widget to toggle between Auto and 100%.
If I leave the setting in Auto from within settings then it seems to work. Brightness widgets seem to break the auto functionality.

Hmm, I don't use a brightness widget. The light of the softbuttons go on if I cover the light sensor, but the screens stays in high brightness.

Must be an all around bug then. If you turn the Atrix off and back on then the auto brightness functionality is restored.

This must be an Android thing. My Atrix does the same thing, as did the Nexus One I had before. I've had several (high end) Nokia's that dimmed/brightened perfectly. After 5 seconds, they would brighten (or dim) accordingly. I was hoping Motorola was better at making phones than HTC (the KING of bad battery life). We ALL lose here. Our precious battery life is being drained by the poor execution of a simple function.

This is a stock android thing (problem). Custom ROMs can allow it to dim and change brightness smoothly rather than in discrete steps (Cyanogen).

That's what I thought. I found this free app called "esdimmer". It supposed to be for Galaxy phones, but it's somewhat working on my Atrix. Does this function work any better in Gingerbread?

Well it's good to hear that it's a stock android problem and not the actual phone. I did find a way to get around this problem but it's very limited. You can get the screen to dim by first putting the phone into standby and then press the standby button once again (which gets you into the lock screen). You'll notice that the screen then dims (if coming from a well lit area/room to a darker one).

Do you experience brightness issue?

I've noticed weird brightness issue at Auto Brightness turned off and when I set it at full. It is actually going even brighter when is brighter outside and it's getting darker again when going into darker environment and it is making me crazy because firstly I don't want my battery to drain more when using brightness sensor and actually don't like the feeling of brightness going up and down that's why I TURNED OFF autobrightness. Could you reproduce the same behavior?

Yes i have this when dark mode is turned on, Even with Auto brightness off it will still change the brightness when i am outside in the bright sun and it also changes the way the text appears adding sort of black lines on the edges of the letters (to give it more contrast ?). It's a feature not an issue i think it also doesn't happen indoors even when lights change. For some reason it only happens when it's very bright outside.

Yeah, but every feature should have "turn off" button, but Xiaomi couldn't help it with forcing something on us as always...

Under Settings/Display/Contrast & colors try using either Increased contrast or Standard. NOT Automatic contrast.
