Hello,
I got a problem with my flashlight.
It turn's randomly on and off but it's only for about a second.
It doesn't matter if the device's screen is off or on or if the device is connected with the pc or not.
Also the flashlight turrns on for about a second if I restart my device. The flashlight turns on and off and then the screen lights up.
Is there a known bug with an app or radio? I tried already two different roms and two differentt radios.
If there is no way to solve the problem, is there a way to deactivate the flashlight so no app can use it?

Hello all,
I found out, that the Flashlight turns on if I touch the Desire at the top left of the phone. Exactly at the intensity and proximity sensor.
Is there a known Problem with the Desire?
Never heard of it before, but damn that must be annoying
Are you using original rom?
Yes, It's very annoying...
Yes I'm using a pre rooted original Rom. But I tested already other roms.. same problem...
Sent from my HTC Desire using XDA App
Sounds weird, but if you did not do a full wipe when switching ROMs then that may be a cause I'd imagine.
how about removing the Flashlight.apk and install it again
have you tried other application for use the LED as flashlight, like teslaLED etc?
Having the some problem here, and my charge led light has also stoped working but the battery is charging, what can I do do fix this beceause its not showing indications
Very same problem with my Desire. Did not install any custom roms, only the updates that came automatically from HTC.
Yesterday did a 'hard reset', (reboot with volumn down button, and choose 'clear storage', but this did not help. I only needed to install every program i again
On the other hand, maybe this was not a real 'hard reset', because the HTC is still on the 'updated version', not on the android version as it was when I did purchase the phone.
Version now is: 2.29.405.5.
It looks like a bug in the system, not a hardware problem, because the flashlight does work sometimes (as described in the first post).
Searching the internet did not work, there are more people with the same problem, but not any solutions (yet).
Any new Informations?
I'm now using CyanogenMod 7 (7.0.3) but the issue is still the same. The radio is upgraded to the newest version. (32.54.00.32U_5.14.05.17)
Is it possible to swap the LED (and Camara) Modul (or board) without replacing the whole mainboard?
Me too
I got the same problem.
bad luck~~!!
I tried many ROM or RADIO or RECOVERY,but can not slove this problem.
The Problem still exists, but I got interessting news.
The problem is caused by the Proximity Sensor.
You can test this very simple:
Download an app which shows the value of your Proximity sensor.
Hint: My Desire only shows 0cm or 9cm value. This is normal, because our sensor is not capable of reporting all intermediate values. Then just hold something in front of the Proximity Sensor (left top of the Phone) and remove it. The value will change and after you removed the thing, the flashlight will switch on for some miliseconds.
Unfortunaly I don't know how I can solve this problem. I also don't know wheather it is a software or hardware problem.
I hope somebody can give some hints or something else.
I am on CM 7.0.3 and I should admit that I use the flashlight quite often. On the high brightness option.
Everything was ok for months but now I get a blueish tint when the flashlight is on. For example, if the normal colour is white (around 6000k), now I get 8000k. Moreover, the led is not as bright as it used to be.
I have never used the torch app, for more than 4-5 minutes constantly on.
Is the led dying?
Got this problem two times already, not even flashing with RUU helped.
Returned my HTC for warranty, when it arrived flashlight worked fine (as per return slip, some module was replaced) but the light sensor was screwed. During phone calls LCD stayed off all the time, it worked only under direct strong light. went back for repairs this time got mainboard replaced.
After a while flash stopped working again and soon after, or maybe at the same time, LCD stopped turning off during phone calls and touchscreen stayed active.
Went for another repair. not sure if i want the same thing to happen again, if it does, i should get a new phone, but i know that it will be a lot of hassle.
Same problem here. This morning the flashlight was working without problems, now it's dead. So this could get the 3'rd mobile replacement within 2 weeks, the 4'th at all. I've already tried CM7.1RC, InsertCoin1.1.0 and the original RUU - no effect...
Now I'm thinking about returning the mobile (possible after 3'rd replacement/repair when You can present the failure in the shop) and ordering a HTC Sensation instead... Maybe this will be better ???
Hey everyone,
Tried searching around the forums, but apparently this issue must be a rare occurence. This problem occured all of the sudden. The G2's LCD backlight is severely dimmed. I had tried disabling the automatic brightness and manually adjusting the brightness but even though the scroller moves freely from side the side, the backlight will only respond to such action for the first quarter of the scroller after that the backlight remains at the same brightness. Also tried AdjBrightness and behaves the same, the backlight won't change for values exceeding 50.
I am wondering if anyone here has experienced the same problems that I have encountered? Are there any solutions other than returning the device?
Thanks for everyone's time

I'm having the same problem with my Desire Z. My phone has always been kept in pristine condition but all of a sudden my screen just dimmed and no matter what I do to brightness settings it stays that way. I tried pulling my battery out as well but that didn't help either . The capacitive buttons and keyboard lights are working just fine it is just the screen that has gone very dim
EDIT: Wow, the problem just kind of disappeared on its own. I pulled the battery again and removed my case and the backlight magically started working again. Weird but I'm happy it's all good
I just had this happened to me. I have taken my battery out multiple times and it still has not solved the issue. Did you ever get your screen back to working normal?
I dont what's happened to my phone as shown in the picture attached the red light is active during active call and when i keep the phone near my ear the screen does'nt turn off, and the battery got empty just after 1-2 hours
i have to say that the red light is on just during an active call
That is the proximity sensor, it emits IR that can be seen on most CMOS sensors (cameras).
This has already been posted on cfX thread and then i found this thread. I have this problem without making calls at all, too.
Hi,
came from cfX to CM 10.1. did a dirty flash (cleared some apps data) without too much trouble. But there is one thing i encounter quite regularly after a dirty flash. Yes, i know i should do a full wipe but the fact that the problem occured already on YellyTime, CfX, a MIUI rom and this rom after a dirty flash makes me wonder...
its always the same: no problems at daily use but randomly the (i guess) IR sensor starts to glow weakly red on the top right corner behind the grill. As soon as it starts, battery drain is pretty high and there are only hours left for my phone. There is no obvious app with a higher than usual drain.
This is not a request for a fix, rather a call to the community out of couriosity
if somebody maybe has an idea he/she could save me from some full wipes (2 step auth is a pain here)
have a nice evening everybody!

after doing a full wipe and installing cfX SR2, situation got worse: now the phone screen stays black occasionally if the red light is on and i have to pull the battery. One thing i noticed is that it mostly happens when there is an internet connection
As has been said allready it's the proximity sensor, not a light.
Install Proximity recalibrator to adjust the threshold values.
ah ... i´ve read your reply too late. already did this

Hi guys,
just came back from me business trip and realized that.. I have posted something totally useless.
So I came back, with the same request, but properly explained.
I have and issue with my Desire HD. There is a strange problem with the magnetometer. I took me a while to find out that is connected to it, because.. sometimes by screen just remains blocked. There is no response from it to touch. After some seconds (between 1 and 20), it works. But, the compass is not working (if I check with some sensor application it says that magnetometer is not present.
Sometimes, the best workaround is to disable screen rotation (that is also somehow strange to me, as I don't really see the connection).
After a factory reset (install new ROM, etc), everything is OK until I use the GPS the first time.
So, the questions now:
1. As the sensor works (sometimes for days), I expect to be a 'software' problem. How do I manually reset the magnetometer? I have read that for Galaxy (for example), you can do that by getting in some hidden factory menu...
2. Is it posible to disable the sensor totally? I would not like to do that, as I would like to have the screen rotation, but it can be handy to be able to enable/disable it.
Thanks for all your answer
Hi there
first of all, I have to excuse for my (hopefully not so bad) english, I´m simply not a native speaker. But I hope you´ll all get what I´d like to express and we can communicate.
Anyway, I´ve got a problem with my Tab S4 and I´m hoping someone can help me.
I´ve noticed my S4 behaves weird in case of Display brightness/contrast. I´ve set the brightness to maximum and disabled the dynamic brightness. But when I´m watching a movie and the sensor/front facing camera gets exposed to bright daylight the image seems to get brighter or the contrast gets boosted or something like this. When I put my hand in front of the sensor to cover it from the light the image gets back to normal.
I´ve already contacted Samsung about, and theyr first reply was to disable dynamic brightness (so they did not fully read my first mail, there I explained that I´ve disabled it) and then suggested a soft reset (great euphemism for turning it off and on again) and because this didnt help either a hard reset.
I have a felling this also wont held to get rid of that problem, but will try it in the next few days when I´m not able to solve the problem. Does someone has any idea what could cause the problem? Or how to solve it?
Oh and bevore I forget it, this happend while watching a Video on Amazon Prime Video, I dont know if this also happens with other apps because I did not test it yet.
Mine does this too, its most likely a feature where when the sensor detects sunlight hitting the screen it turns the brightness up higher than you can on your own. My Note 2 had this function and someone wrote a neat little app that allowed you to use that max brightness anytime you want, obviously required root though.
