There are two listed tweaks for preventing the Diamond from turning the screen off during a call. I've done them both, and nothing happens. Are these tweaks confirmed to work for all phones, or just on some? It says the "Sleep" one works on european ROM -- do all European phones have the same rom?
I'm having a simmilar problem... It seems that the screen turns off after a set period of time... I thought that the light sensor was supposed to only shut the screen off when you bring it up to your ear, light gets dull... I have the phone sitting in well lit room and done got near it yet the screen still turns off..?

I've read that if you remove the stylus while in a call, then the note program comes on automatically, but the screen will also stay on until the call is finished

yes, you are right and this is in my humble opinion the best solution. this way even if u touch with yr ear/cheek the screen no funny noises and no unwanted programs popping up not to mention that this way u have the choice and if you don't need the screen it stays black.
If you want to turn your screen back on during a call just simply press the round center button once and it will turn back on. no need for any hacks.
Thanks for the help
From what I have read, the phone screen should only turn off the screen when you bring it up to your ear/there is low light on the light sensor in the handsets ear speaker... My phone's screen shuts itself off after 3 seconds or so, doesnt matter where light is... If you just disable fastdormant (1 to 0), does the phone still shut itself off after x seconds or does it wait until there is a change in light?
Can anyone confirm/clarify the above???
Also is it possible to reactivate the display once the phone detects a sizeable change in brightness again? From reading the links posted, no one has found a solution for this one yet..?
The screen will not turn off as long as you continue to touch the center button during call. The default setting work fine with me until I need to get information during a call yesterday. The center button touch allow you to use other functions during phone call.

My problem is that my phone won't go into the sleep mode when calling. Covering the phone doesn't help (I've tested the light sensor, and that still works)
For me this feature is a positive thing so I would like it to work again.
The registry entry for the EnableFastDormant is still on "1". The HTC Phone Skin is loaded (without that skin it doesn't work either).
When searching the forum I come across people who want their screen to stay on... I want the opposite to happen again. Anybody a suggestion?

Check this reg entry as well:
HKCU\ControlPanel\Phone\Sleep - 1
HKCU\ControlPanel\Backlight\LightSensorPollingEnable - 1
HKLM\Drivers\BuiltIn\RIL\BatteryTimeoutInCall - 5
HKLM\Drivers\BuiltIn\RIL\BatterySuspendTimeoutInCall - 5
Also,
Start - Settings - System
Power
Advanced
Check the following:
Turnoff Backlight if device is not used for 30 Sec
Turn off Device if not used for 40 sec
All the best
Note: After changing Registry Entries.. (if you had to).. do a soft reset.

Problem with 1.93 ROM
Hey,
I cant seem to get the screen to stay on during a phone call using Asia WWE 1.93 ROM....
I have got BattTimeoutIncall = 0
BattSuspendIncall = 0
Phone\Sleep = 0
EnableFastdormant = 0
but the screen still turns off if i leave the phone sitting on the desk under light exactly when the call time ticks over to 4 sec (0:03 to 0:04)...
Ideas anyone, is this an issue with v1.93 rom?
Thanks.
this works!
Does this still enable the light sensor???
Still want the light sensor to work - i.e. turn off the screen when i bring it up to my head...

This is actually the best option because it turns off the screen when you want to conserve battery life.
So I just press the Center button when I want to see the screen to use the keypad or speakerphone.
Also, I have disabled the phone shade (curtain) by doing this:

HKLM/Software/HTC/Phone/PhoneLockEnable = 0
the iphone switches the screen off when it goes to your head then turns back on when u take it away. is there a simple app for this??

To add on to that the phone also goes to sleep when the call is connected and its just a matter of pressing the power button to get it to wake up again.
mine doesnt
Well mine has always went black when it goes up to my ear, but it would be nice if it came back on when removed from my ear.. although we dont have a proximity sensor, i dont see why it coulnt work with the gsensor/accelerometer. all it would have to do is go on when the phone is put back in the upright position

is it possible to in fact use the light sensor? it obviously recognizes something when it turns off, maybe write up something saying "when dark below 'x' threshold, turn off screen. when bright above threshold, screen on. you would have to press the screen somewhat snugly to your face, but it sure beats nothing.

It should be possible, but no one has done anything with the light sensor of turning it back on. I'm thinking that the polling of the light sensor turns off when the screen is in standby. If we can somehow get that to work in only incall (so it doesn't have battery issues), then it should work, when it goes from little light to more light, it should act as close to phone to far away from phone.
One could even use 2 sensors for it? Maybe the Light-Sensor and the G-Sensor. So when u bring the phone to your ear the light gets dark an the position upright. (the phone turns the screen off) And as soon as it get brighter and the position is change to normal (whatever that is ) it turns back on.
I reall would love to write something like that. But so far i have no clue of writing anything for that phone. Does anyone know a tutorial for writing software for a pda?
Thx
Come on guys this would be soooo great

It doesn't actually do that when you put it up to your ear. It's a WinMo setting to put the phone in standby after a call is launched or received. What you preceive as behavior is actually a timing thing.
The guy from pocket shield managed to combine these two sensors, g-sensor and light sensor, to work together as locking/unlocking behavior.
maybe some g-sensor and lumos code can handle this thing... and create one cab solution here...
if some one could write this code it would be an AWESOME addition to the Phone. I would personaly love this as im sure many others would.
Thanks.

My friends G1 is unresponsive whenever the screen is closed, but seems to work when sliding it open. The funny thing is, while the device doesn't perform any actions when the screen is closed, it still seems to be responding to touch. When the screen is opened again, your touched actions will "catch up" and the phone responds. This happens from recovery mode as well as in Android.
Can anyone help?
Anyone? Please?

The phone is in standby/sleep mode while screen is off, so you cant use the touch screen. You must double tap Menu to get to the home screen.While in recovery mode you cant use the touch screen cause you have to use the hardware buttons or the trackball. Im guessing you were unaware that the phone goes into sleep mode. When you slide the KB the phone wakes from sleep mode and allows you to use it.You only have to slide it when you need it not just to do it randomly.
No no, sorry if I worded it incorrectly. The screen is on and it is frozen when the slider is closed. Once you open the keyboard, everything works fine. As soon as you slide it in, the screen freezes on its current display and stops updating.

Its a 2.1 ROM by Kingx
The screen behaves the same in and out of android though...such as in the recovery (JFv1.4) console. If the screen is closed, the screen "freezes", but the frozen picture is still displayed. If you slide the screen ouţand expose the keyboard, it works fine. The phone otherwise operates normally, as does the standby mode.

JF is super old and lacks many features from Amon_Ra. But it's based off of Cyan 1.4 recovery. It makes a lot of things easier like partitioning,wiping,backup,restoring roms.
Alright,
Home now with his phone. I swapped JF's recovery with RA. The issue still exists, and I'm wondering if it's hardware related...
This is frustrating. I don't know if I can fix it for him...
The problem seems to have gotten worse on its own. If the screen is closed at all, the screen will go black with a slight image shown with what seems to be an unworking backlight. However, upon sliding the keyboard open again, the backlight does not return until the device is rebooted while leaving the keyboard open.
Edit:
The backlight seems to come on sometimes when you slide the screen open...

You might wanna wipe and install another rom to see if the problem stays.There might be a hardware problem with your phone.
I've wiped and tried a couple of other ROMs but the issue persists. If it's a hardware issue, is there anything I can try to fix it?

It could be the ribbon that connects to the display.If you can find the assembly guide you could replace the broken or loose piece.But i'm not 100% on which part of the display needs to be replaced.You could ask someone at T-Mobile or at a electronics store what the problem is.HTC offers a free 2yr warranty so you might be able to get a replacement.
Bumping this to see if this was ever resolved. Having the same issue, and considering replacing it brand new, but wanted to know what exactly needs to be replaced so I can order it.
I currently have a stock HTC One in Canada on the Telus network.
The last few weeks i noticed the LED light growing dim. About a week ago the phone rebooted itself only to say it had an issue and that it was not shutdown correctly.. and asked if i wanted to report the problem to HTC.
The phone the froze with the Screen on but a black background.
After 15 minutes i powered off the phone.
At this point the phone would not power back on.. when i plugged the power in to the phone from the wall the phone would not indicate that it was charging via LED.
I tried booting no response.. no vibrating,.. just slight flashing lights on the Home/back buttons
I ended up booting up the phone by shining a bright light into the light sensor while holding Power and DOWN volume..
Phone has been working fine ever since, however still no LED.
I did a factory reset and still no LED.
Has anyone see anything like this?
I want to root and install Google Edition Android however if the hardware is faulty i dont want to risk voiding the warranty and being stuck with a faulty phone.

Unfortunately I have not been successful getting the LED back.. I am debating sending the phone in for Warranty work... or just sucking it up and rooting/flashing custom roms.
My main concern is that there may be a bigger hardware issue going on internally.

Try this: in dialer type *#*#3424#*#* (3424 = DIAG), that will bring up HTC internal diagnostic, there's a "LED Test", select and run it to see if it's a hardware defect or not (you will get Orange and Green LED tests).

Thanks for the info.. Just tried it the LED test .
To my surprise the Green and Orange lights actually show up but I have to hold it to my eye and block out any external light to see anything.. kind of defeats the purpose of an LED notification light..
I guess the light works its just extremely DIM.
Any way of controlling the LED light brightness?

Don't know, but I just ran the same test in a very well lit environment and the Green and Orange LED are quite bright... I don't have to "go look for them" they pop out nicely.
Are you using a cover of any kind? Or maybe the LED has somehow shifted it's position and is being partially covered by the speaker grill? Hate to say it, but sounds like a hardware issue. Sorry
Hope someone else has other ideas.

I also have the same problem: when it is charging and when it is fully charged the light works OK but doesn't flash for notifications. But it worked OK some time ago. Actually, when I think about it, it seems that the problem started after I had updated to the current firmware: Android version 4.3, HTC Sense version 5.5, software number 3.62.401.1
It must be issue with firmware/software because LED test works fine.
There's another thread similar to this one and someone there figured out the solution - you do a factory reset but, when the phone reboots, you do not restore everything using your Google account. Go through the setup as normal (without restoring) and once that is complete then you can add your Google account details.
It means you have to download and set up your apps again, but it is worth it to get the LED working.
HI I had a similar problem I cleaned out the hole with a needle and all is well, pin came out dirty (the one on the grill dirt was blocking led )
I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?
