Fix to Disable Navigation Button LEDs - Epic 4G General

You know the four LEDs that light up along with the keyboard LEDs at the bottom of our phone? It pisses me off that Samsung wired these guys in with the keyboard and literally made it impossible to disable them using software fixes. And I've set it to 3 seconds but that just doesn't cut it. I want them disabled, permanently, until I decide they should be turned back on. Well, I took it to the next level.
Cutting a piece of black electrical tape to just fit over the four, bottom buttons, I place it over the LEDs and BOOM, they were gone. My eyes will no longer tear up when I'm on my phone late at night while laying in bed. No longer will the screen be set to a healthy, dim brightness only to be overpowered the four LEDs at the bottom each time my finger touches the screen.
The capacitive feature still works fine, and I've lost no functionality with this fix. I'd post a picture but I'm having some issues with my digital camera.

the hermes keyboard.. the way I need it

Hey all,
Does anyone know of any means to turn off the keyboard backlight, force it off no matter what the situation? As well, does anyone know of any hack or program one could use to force toggle the keyboard on and off?
Aside from this, does anyone have any pictures of the keyboard open? I specifically want to see how the leds are arranged in there. I want to remove the blue leds and replace them with a few white or red ones.. or, put a resistor in, so that the blue leds are EXTREMELY DIM compared to their brightness now.
It's annoying to me that the keyboard leds are so bright, that they actually outshine my main screen (which has the brightness turned down).
Any ideas, anyone?
Hi Brad,
Most of the pics available had no shot of the keyboard PCB removed... I am also looking for it. I wanted to shim the right side of the keyboard since that part is lower than the left side.
Is your keyboard keys also going a little sunk from left to right ? you need to feel/look for it hard, since it is just a matter of half millimeter.
No.. no issues with my keyboard, other than I can't even stand to look at it. I literally just can't look at it. I have to close my eyes when I type. I think I have some extreme blue-light sensitivity or something.
My Hermes is fairly new, though... but again, the keys all seem fine. I can't *see* the keys, but they feel fine.
I just refuse to stare at extremely bright and annoying painful to look at things. I mean, didn't these guys notice that the Hermes seemed to be all blurry, when the backlight was on? And really bright??

Proximity Sensor Help

I'm having trouble with the proximity sensor on my HD2. It works if the phone is pressed up directly on my ear, but if I move it away just the slightest, the screen comes back. Is there somewhere I can access the proximity sensor settings, and give myself a bit more room? Like, say, anything inside an inch shuts off the screen?
ROM info is in the sig, and I'm using the HTC phone dialer, if that makes any difference.

Aw balls, I hate it when there's a thread for this, and my impatience with searching failed to find it.
Thanks!
Doesn't sound like that app does anything for the sensitivity, unless i missed it. it just makes the screen stay off after the sensor is activated.
However the point of the proximity sensor is to shut off the screen so your ear isn't pressing buttons. If you've got the phone far enough away from your ear to reactivate the screen, then there's no longer a need to turn off the screen to prevent ear dialing.
If you're worried about power savings, the screen should shutoff in a minute or so, depending on your screen timeout options

correct, I haven't found a way to change the sensitivity for it, just turn it on or off. I believe the way the sensor works like a motion sensor in a store, either you are there or not... Hardware driven on sensitivity, not software.

I actually posted about the sensor in another post. The sensor is just an IR LED and a photo diode. The photo diode looks for the reflected IR when the phone is near something like your ear.
The IR LED only turns on during a phone call. Try this get a digital camera with a live preview and aim it at the 2 dots where the proximity sensor is, you'll see the IR LED light up when you initiate a call
The same photo diode is used to alter the screen brightness depending on the ambient light that hits it

Opposite side of the LED flash

This might seem like a dumb question, and I just got my MTS 2 days ago, so I'm still learning about it, but at the top of the phone, where the LEDs are, what is the function of the opposite side of where you hear your calls? Is it there for looks or does it have LEDs in there also?
it is the proximity sensor... it is what "locks" the screen so you are not activating it with your cheek while on the phone... it also blacks out the screen when you are on the phone
I've always wondered what this was too... thanks for that information.
it also turns the button lights and keyboard lights on/off at certain light levels...that way when its bright it turns the lights off and when ur in the dark the lights come on...i love it!

that seems to be incorrect because i use the headset and if i lift the phone to a certain angle the phone screen turns off, but when i tilt it back down it turns on again. i will look into this more but from what i have seen it is just there to be a little more symmetrical(would you want a phone with asymmetrical looks to it)

no hes right it IS a proximity sensor...go where theres some light and open the keyboard and see if the keylights are on...if so, try to make it brighter...(shine a flashlight at it or something) and the lights will go off...then put your finger over the sensor and the lights will come on...it works, try it...definitely not just for decoration...what you are experiencing is a perfectly normal effect of the proximity sensor doing what it does...no reason to look into it...
or download "Sensor List" from the market and look, it lists the prox. sensor and its data...put your finger over it and watch the output jump...
or run adb logcat and put your finger over it and itll come up with a entry about the light value changing...

without the headset try calling your voice-mail in a lit room and hold the phone away from you and move it all around an at different angles, you will see it makes no changes but just by putting your thumb over that spot it kills the screen and as soon as you remove your thumb it comes back on... might want to actually do some reading or testing before saying someone is wrong. not only would a quick 5 second test show that it is the light/proximity sensor, or you could try a quick google search
You can also have the left light flash for missed messages.
i was doing some testing and i am retracting my statement, you were correct wulf and i am sorry that i doubted this.
hey it's kewl we all make mistakes

Blackout screen during phone calls

what feature is this? when i put the phone near my face the screen goes blank and when i move it away from my face the menu lights up, pretty cool. anyone know how it works?
Not sure of the technical aspects, but I've heard it has a sensor - much like a car has headlight sensor. When it gets dark, the headlights go on, when it's daylight, headlights shut off. Phone is the opposite, dark to your face - light off, pulled away from face, lights up. I agree, cool feature - helps to conserve battery a little bit too.
It's a proximity sensor. The screen turns off so that it doesn't accidently register the screen touching your face as a touch input (aka your face touches the 'end call' button while in the middle of talking).
Lol all phones have done this using a proximity sensor for about 4 years now;-). It's nice though! Otherwise your cheek would press all kinds of buttons during a phone call, likely the end button as one of them.
These have been around for about six years now on mobiles.
Yes, this is nothing new on phones. If you're interested, look very closely at the phone's front, to the left of the speaker as you look at it. Opposite side of the camera lens. You may have to tilt it a bit, and bright light will help. You'll see two very small transluscent spots. One is the light sensor, the other is the proximity sensor.

Screen toast after only 2 years?

So my Simple Touch Reader is about 2 years old and I'm pretty sure the screen is already toast (or almost toast) . I have to swipe tons of times to unlock it, and when I actually can unlock it, swipe to turn page almost never works...I have to use the buttons. It's like my Nook's screen has lost all sensitivity.
After only 2 years it's pretty disappointing.
Any ideas on what might be the problem...and how to fix it?
Thanks.
Clean the screen.
The IR sensors are sensitive to any crud that may have collected.
Use a lightly damp Q-Tip to clean the inside of the bezel.
It would be interesting if I could see that Nook now.
When there is no finger on the screen only a single IR LED pulses in a slow fashion.
Once a finger hits the screen, this low power mode detects it and switches
to the full left side and bottom side IR LED scanning mode.
Using my IR detector diode method you can hear exactly what is going on.
See: http://forum.xda-developers.com/showpost.php?p=24232518&postcount=9
I'll try giving it a good cleaning. I can't remember the last time I wiped it down...
