I know there is a BRIGHTNESS setting for the TP2's screen, but is there a CONTRAST setting anywhere? Any screen that has a black or dark color to it is not as sharp (on my phone, anyway) as my TP1 (Fuze). A sharper black will make all colors appear more brilliant and sharper. Is there a way to adjust the CONTRAST -- whether by a control setting or a registry tweak? Any help would be appreciated. Thanks to all in advance!
The screen has neither a brightness nor a contrast control in the normally-accepted sense of those terms. What it has is the ability to vary the intensity of the backlight, which is quite different. Even if it did have a contrast control, that would affect whites, not blacks. If black is not dark enough then your only option is to make the backlight dimmer. That, of course, will have no effect on sharpness.
Does G2 track pad have color capabilities like the Nexus One trackball?
Don't think so but not too sure. I think I read somewhere that it turns blue when connected to a bluetooth headset, but someone tried it and it didn't change for them
Generally speaking, any white LED is actually an RGB LED, just because of the way that LEDs create light. I have no clue if that's the case here, but that's how it usually works.
So the file lights.vision.so refers to it as an RGB LED. It also gives an option to set the color. How do you modify that (or can you)? I have no clue. But that file at least refers to it as an RGB.
based on my experience theres different kind of LEDs some with multi colors some are sound sensitive and some are RGB only, therefore you cannot use purple on an RGB LED. BTW the lighting on the trackpad is the same as the one on the physical keyboard if you can change the trackpads color you could change the keyboards do, but you cant, i dont think you can change the color of that. btw the nexus one's trackball is an LED that changes color i dont know if its multi-color but yea the g2's trackpad doesnt have that

Uhhhh…I think you're distinctly unaware about how LEDs work. LEDs emit light of a certain frequency when current passes through them. "An" RGB LED is actually three LEDs, a red, green, and a blue, which together create white. However, by tweaking the brightness output of the individual LEDs that make up an RGB LED, you can create pretty much any color you want. That's how light works (as an aside, there really isn't such a thing as "white" colored light. You're simply seeing equal amounts of red, green, and blue).
So, generally speaking, if you have white, you have RGB (though they have developed "white" LEDs, they're more expensive to manufacture than simply making 3 colored LEDs). And if you have RGB, then you (probably) have the ability to create different colors.
Now, the possible kink in the idea here is that it may be that all three LEDs are run in circuit, so if you have one on, all three are on; you can't modify brightness individually. I don't know if that's the case here, but if it is, then there's nothing we can do. Someone who's done a teardown would probably be the only ones who would know.
PS, have you looked at a G2 before? Because the trackpad and the keyboard are on different parts of the phone. It's physically impossible for them to share a backlight. Not to mention the fact that the trackpad acts as a notification system, and flashes intermittently. Don't think you want your keyboard backlight doing that.
what i meant is the keyboard and trackpad use the same kind of LED, (not running on the same kind of circuitry. yeah someone could prolly tear it down and edit or tamper the LCD by themselves, i know what RGB is btw, i just did not know that white is possible. RGB = red green blue = different combinations of density on R or G or B = different color.
Any white led where you can see a bluish tinge is a white LED that isn't RGB. The trackpad I have a suspicion that its probably one of the newer LED's that's just a blue LED with the special coating that makes it white.
Sent from my T-Mobile G2 running Cyanogenmod.
As you can see in the attached results the device is has a green tint with red's that drop off in the blacks. Currently there is no way I know of to correct this. Screen Adjuster and Filter Your Screen only adjust the RGB Offset (Blacks) If you calibrate to the white point the black shifts very red. The device also appears to have a ridiculous gamma of 2.78
I used HCFR with a Spyder4Pro and the AVS HD 709 Patterns.
I know there are some programs that can alter display color temperature depending on time of day and global user position on Earth.
What I'm looking for is a program that can do the same based on light sensor data, I mean that outside in the sun, display have a high color temp, let's say 6500-7200 C and when I get into a dark room the display will not only decrease brightness like it always does but also change color temp to for example 3400 C. Blue light filtering like that is nice not only late at night before sleep but also while spending a lot of time indoors even during day.
So my question is - did anyone ever seen an app that can do that?
Interesting idea. I haven't heard of an app that can do this, but I'm sure with some Googling you'd be able to find out for sure.
I had a quick Google myself and it turns out that some high-end Samsung phones do this by default. Their light sensors detect Red, Blue and Green and change the screens colour to reflect your surroundings. Its called Adapt Display.
I'm not sure the light sensor on all smartphones can detect colour range tho, I think most are only capable of detecting luminance. If that's the case I'm sure someone could create an app that reads colour data from the camera when the light changes and could apply that to the screen hue to more accurately reflect the colour temperature of your environment, but I doubt it would be that accurate...
Yes, they can adapt but you can't make them change color with light intensity. This is actually what inspired me to look for better functionality
Hi there
Is there a way to change the colour of the led notification light for each app in built into the phone.
If not then is there a reliable app that you have tried and found to be working well.
Thank you for your time.
You can try LightFlow app. Keep in mind the 5Z doesn't have a traditional RGB LED, it only has a Red & Green type LED notification light so the possibilities of producing different colors by mixing are limited. However some colors are still possible but don't expect much brightness in them.
Thank you for the information.
