I know it takes some time to look around and find it, but somewhere in this forum somebody explains what those led-like things are... nothing but some sensors...

[Q] track pad light

The track pad had a very dim red light in it when you wake the phone youll see it, its nothing like a notification in the center right side... Just questioning what it is and if we can get to it :/
once you see it youll always see it
I had no idea there was a light in there...ive noticed the red tint to it in some lights but assumed that it was something to do with the touch sensors

Yea the corner by genius button is just like yours.
I havent noticed a light on the trackpad tho. I even looked around for an app or something to activate it. No luck tho....
its not a light... its a dark red lens that covers the optical trackball... there is no (visible) light what so ever in there... you just held the phone at a odd angle in the right light...
go look at any other optical TB if you dont believe me...they all have a dark red hue (regardless of the battery status on the phone)
unplug phone from charger, pull battery and look closely, it'll still be red, and without power nothing could possibly be "lighting up"

i wasnt saying it was like a led its just a dim light thats behind it which looks red because of the cover on the trackpad... but seeing that made me question if there was a notification light down there like on the nexus one's trackball for instance
There is definitely a light on mine. I see it every time I wake the screen.

i though it may just be light from the menu button peeping through but itll do it when the keys arnt lite up :/ hopefully its an led and we can get it brighter for notifications cus that'd be sick (thats one thing i would of liked how the g2 has it going around the pad)
Afaik the only light down there is infrared... if you can see it you got some sick ass eyes, or the lens on the trackpad is somehow reflecting the light or something... but like I said turn the phone off and pull the batt and I still see a faint red hue in the trackpad...

There is definitely a light in there that illuminates for a brief moment towards the left hand side of the button when you wake up the phone with the track pad. It is no reflection of the infrared, it's a light. Do it in a completely dark room and it will be obvious.
I don't have this at all. If it's a light, it would certainly be more obvious, no? How could a light be so dim?
I noticed this last night when I was cleaning my phone. It is definitely a dim red light.

lol u got some sick ass eyes
Yeah definitely seeing it now too once it has been pointed out. It's more in the left center of my track pad.
I think it's just the trackpad sensor light, similar to the laser light under your optical mouse.
I don't see it doing anything but registering where your finger moves.

[Q] Notification Light Location

Is the notification light visible while looking at the phone from the front? From what I hear the location of the light is on the top of the phone and not on the face like all phones i've ever owned.
So if the phone is laying down with the screen up but the top side away from you, could you see if you have a txt or email while your phone is in silent mode?
Thanks

I just tried it and... No, you actually CAN'T see it if you're looking from the front onto the device and the room is well-lit. On the plus side, the LED does support the full RGB-Color spectrum including white.
Oh snap. Well thank you for reporting that bit of info.

Backlight bleed?

Hi everyone just today i noticed what i think is a small backlight bleed. Its at the top of the screen on the edge and you can only see it on fully black baground. I will try and post pics later tonight. Can anyone please check there phone on black screen in a dark room all around the edges especially at the top and let me know if this is normal. What i notice is you have too look carefuly and its better seen from further distance then right in your face. Thats why im wondering if it is light bleed at all.

Edit: Here is an image i drew onto pink Arc for some reason lol (sorry i coudnlt caputre it) but it will give you an idea of what i mean.
Notice the top how it goes a liitle more in that is what i am talking bout.
Anyone not scared to try this? Lol its not a big deal just wondering, but i think all lcds have it to some degree. So if someone is wiling to check i will really apreciate it.
Sent from my LT15a using XDA App
nope don't see any bleeding. but if you check the ipad2 now that's a light leak )
oh yeahh thats not what i am talking about That is huuuge light bleed. The one i see is only on the edge and it kind of trembles it is almost like a white shadowbut only goes a couple milimeters on the screen. Its hard to explain lol i feel like an idiot. I will try to picture it.
Edit: I think my OCD is kicking in for no reason lol its barely there its probably the way it is with any lcd.

Not really a question... Just an observation

Does anyone else glance at the phone and think the front facing camera is a dim blue led?
Nothing I can do about this, but I just wanted to know if this has been bothering anyone else.
That and with the always on screen, I keep thinking I'm the worlds most popular guy today but really no one is texting me... haha
I think it's just going to take some getting used to...
I think it might be the iris sensor. It's an IR sensor so has visible light filter that I've heard reflects blue and can look like a blue LED.
