[Q] What is the top left sensor? - HTC Amaze 4G

So maybe somebody can help me out. I know the top two sensors on top left of the amaze are proximity and light sensor. Which one is the one on the left of those two?
Last question, the top left sensor is flickering a dim red color. Is this normal? It even stays on when I turn off the screen. It's noticeable in the dark. It goes away if I restart the phone. Anyone also have this problem?

It's the light that emmits if the phone is near your face or far to turn off or on the screen.. you supposed to get that effect when your on call mode and when your not it should turn off automatically..
I think why it kepps blinking because the red light if it is near on your face the red light bounce back to the sensor telling that the phone is on your face thus why the screen turn off..

Well It's blinking when I'm not on a call. It's staying on till I notice it and trun off my phone or restart it.
I do notice if I'm on a call for more than 5 mins I have to hit my power button to get the screen to show up to end a call. Shouldn't the screen com back on once its away from my face? Maybe I have a bad sensor.....

its normal all the phones do that, its the proximity sensor, tells your phone when your face is near the phone so the screen goes off to save battery and also prevent accidental pushing of buttons. If you have in pocket mode checked (always checking to see if its in your pocket to increase the ringtone) in the settings it's probably always on which wastes battery, you could turn in off under settings--> sound.

I swear I saw a post just like this like a month ago.

Screen is NOT turned off actually by proximity sensor during phone call 2.1

Hi, may be it's just my x10i, but last night when I was making phone call in the dark I noticed that the screen is NOT turned off actually by the proximity sensor.
Yes the display went black if you put your finger in front of the sensor. This prevents any mistyping on the phone which is good. However, the back light of the display is still on. By this I mean, the screen is black but it's still bright, which made me feel very strange as it will continue to drain the battery. Anyone else discovered this? Any solutions?
hmm, mine doesnt turn off at all during calls, it will however turn off after 7-8 sec in call.
are you on 1.6 or 2.1?

Button Lights Tip/Trick?

Maybe someone has posted this tip already, anyway here goes.
The light sensor for the home-menu-back-search buttons seems to only kick in mainly in the dark, and off on times in dim lit rooms.
If your phone does the same, put your thumb (i am right handed) over the little HTC logo in the top left of your screen, the sensor seems to be in that location, with the phone on the home screen (unlocked) see if the buttons light up when you do that, mine does.
So, you will get them to come on when needed
I'd love to find a way to do the exact opposite without strapping a flashlight to the top of my phone

Strange behavior when dialling

Hi I have just got a HTC radar as a company phone and am getting some odd behavior when dialling
Sometimes it works like expected other times when I press call the screen goes off and will not come back on no matter what I do until the other end pick the call up
Now that's not so bad until you call voicemail when nothing makes screen come on ie tried moving away from anything (in case proximity sensor turning it off ) tried the on/off button volume even camera button nothing works so I can't press option 1/2 etc
Only way I can end the call is to remove bottom cap and take sim card out
This happens on around 50% of all calls and is really bugging me , if its connected to a bluetooth car kit ,the car kit can end it ok
Everytime on bt kit the screen goes off with pressing call
Anyone else having this problem?

Do you have a screen protector? If so it could be one of poor quality and is interfering with your screen. Remove it if you got it. Also it can mess up your ambient light sensor/proximity sensor.

Have reset device still the same I'm guessing it has a problem , sad to say but HTC aren't impressing me lately even thinking of replacing my sensation with a galaxy nexus soon :-(

I'm having the same issue too. But i do have it all the time, with every single call i make.
Lets test something here:
Grab a flashlight and turn it on
Cover the light sensor in the upper left with your finger and make sure the 3 capacitive buttons light up.
Uncover them
Now shine the flash light directly into the light sensor
Did the lights turn off? If not get your phone replaced. If they did then you or something is covering the light sensor. The light sensor can turn the screen off at around 1".
I wrote to HTC, they replied after 1-2 hours:
"this is a functional problem caused by a sensor inside the phone" ... "if you can please do get a replacement phone if you have just bought the phone"

Tried this but nothing happens while call is active , I rang someone today got their voicemail I left a message but after my message I couldn't end the call I had to connect it to my car kit and use that to end the call
Time for a new handset here as well I think :-(

For me, the light turned off. In fact I do not need to shine a torchlight. If I cover the top part of the display the 3 capacitive buttons light up. If I uncover, the light disappear. Any ideas? The screen is turning off every time I make a call.
That tests the ambient light sensor(s) - most phones have 2 or 3 - but it doesn't test the proximity sensor... (because the button lights should be tied to the ambient).
Either way, I have not heard of this issue, though HTC has pushed out a firmware update over zune for the Titan recently. I'd recommend to check that, and if there is no update/doesn't fix, then replace the phone.

Is my sensor working properly then? I have a screen protector installed. Is that the problem? I have not tried taking off the protector yet.
You should try that. Some cheap screen protectors can mess with it. I know this was the case with some protectors on the dell venue pro early on.

o.0!? The proximity sensor is normally a led rangefinder in the infrared frequencies. Light sensor could cause lots of false positives...

Fixed the problem. You must remove the clear stock screen protector...it distorts the sensor.
I've been saying that all along
I did a test. Peeled off a bit of the screen protector, enough to expose the sensor. Made a call. The screen didn't blank. So it's the screen protector.
Hi guys I have just recently bought a Radar from bay and im having the same problem, but this time there is no screen protector.
If I cant get a refund form the seller, can I get a warranty repair seeing as though im a second owner?
Cheers

[Q] Dat Light...?

I'm unsure if anyone tackled or even noticed this one yet, but I noticed that after I unlocked the bootloader via htcdev.com, whenever I make a call, there's a little red light that sits above the HTC branding (left of the notification LED) that flickers repeatedly whenever I make any phone calls. Is this a unlocked bootloader indicator, malfunction, or normal function of the phone? Also, can someone tell me what that light is for if it's not an indicator of a call?

I don't ever get the red indicator light unless my battery level is low.
In fact I don't have any LED light while I'm on a call at all.

I'm not saying the notification LED. It's a separate light to the left of it. It's located conveniently right above the right side of the T in the HTC branding. It's very very faint. The only reason I noticed it was because I was in the dark and I pulled the phone away from my face to look at it.

I'm in the dark right now. I just made a call to my work phone. There is no light.
That's a sensor. It turns the screen off when the phone is by your face..(having a brain fart of what that sensor is called) lol

So when that sensor is active, you can see the red flashing it does?
Edit: Well, you seem to have won the cookie. I don't know why my proximity sensor is actually visible. I just tested it with my thumb. Turns out that that is indeed the proximity sensor.
Mine does the same thing only its completly random. I'll look over and it'll be flashing. I decided to just ignore it a few weeks ago.

I noticed this a while a ago it is the proximity sensor, its not next to the left of the ambient light sensor and it is NOT the led!!, go into a dark room and make a call it'll start blinking...or any app that uses proximity sensor...Also if you have the option of pocket mode it'll probably be running all the time but i'm not sure, it should technically run when you receive a call, but you will definitely notice that it'll blink very very rapidly while you're in a call...proximity sensor!!
Whats weird that I noticed also is that when my HTC amaze fell on the floor board of my truck I reached down to pick it up and passed it in front of my Radar detector the L band went off on the radar detector I though maybe a cop out but nope every time i put the phone in the radar detectors view it started going off, pretty weird just wondering if anyone can explain that, it might be the reason its giving off that red glow
It emits infrared light. Some peoples' eyes are better attuned to see it than others. In other words, some people cannot see the light at all, and other people can see it just find - it all depends on how sensitive your eyes are to the infrared spectrum.
yeah i thought i was the only one with this problem. whenever i make calls the light goes crazy even after the call!
hey so after reading this, because i was also trying to find out what it is myself.. i now know what it is..
but recently i noticed that my phone freaked out, and shut itself off, and that red light stayed on.. my phone wouldnt charge nor turn on until
i took the battery out and out it back in.. has that happened to anyone??
Yea I've seen it to

[Q] Force Capacitive Buttons Lit Up

Simple question, I found answers for many other HTC phones or other bands but not for the HTC One yet. Is there a way to force the capacitive buttons to stay lit up? I am coming from a Motorola phone with 4 capacitive buttons (menu back home search) and find myself having to press the home and back buttons multiple times before actually hitting them.
I've noticed they stay off if you have power saver on. Do you have it off and they still turn off?

I turned power saver off and like you said the buttons light up more now, but I was curious if there was a way to keep them permanently lit up?
I would imagine something like that would have to come from a custom kernel
I wish I could turn mine off permanently. I don't like the color they light up. They're not exactly white and it kinda bothers me (yeah, it's stupid, but whatever).

download NoLED. it has an options to permanently turn off the backlight.
My home and back buttons don't light up at all (if I turn off the lights at night for example they will "glow" however). Power saver is off and I did a restart. Am I missing something simple? I know where the buttons are so I'm not going to send it back to LetsTalk, but it is a little aggravating. I do have the phone in an Otterbox Defender case, but they know not to cover up any sensors.

I do know the light sensor has something do with whether the buttons light up or not. If i'm in broad daylight they never light up but in the evenings it's hit or miss.
My buttons don't show up either. I saw in another thread that they only come on when it's extremely dark. It's quite dark in my bedroom as I lie here, but still they're off. I decided to test it by lying the phone face down on my stomach while I lie here. When I pick the phone back up the buttons are lit, but they almost immediately turn back off. It sucks, because it's dark enough in here that I can't see them, and I'm just sort of stabbing around and hoping for the best. Hopefully a ROM or mod will pop up and allow for a fix.

There's an app called Soft Buttons Light in the appstore. It is supposed to either turn the button lights on permanently (while screen is lit) or lets you turn them off permanently. It doesn't require root.
Unfortunately it doesn't seem to work on my One.
If you cover the sensor for a couple of seconds the buttons will stay lit up.ghetto I know lol but still turns them on
Sent from my HTC One using Tapatalk 2
The tmobile version of the phone has brightly lit buttons, so it appears to be the att version of the software that keeps the lights dim, probably to try to conserve battery. I have both while I'm testing out the networks, and there are several things like that. The dev version of the rom (or an upcoming custom mod?) should fix it.

With mine it only keeps them lit as long as I keep the sensor covered. Move my thumb away and the lights go out. I've developed a habit of holding the phone in my left hand with my thumb wrapped over the top left, shading the light sensor. I hope HTC adjusts the setting or just adds a toggle for turning them on or off.
Maybe a developer could make a widget...
