light sensor, never dims - Desire General

when set to auto adjust, the brightness goes up when light levels increase. fine.
when light levels are low or darkness, they never seem to dim back to low level.
they only dim back if i switch the screen off/on
do i have fault or is the a feature?

Iv heard if you have a screen cover on teh front it can cause problems. I have the zagg invisible sheild, and dont have a problem with it.

i have the same problem... and i canot find a aplication to set up how much light to give at display for each value it gets from light sensor... something like in windows mobile...the autoadjust is crap it hurts my eyes in a totaly black room

The official HTC screen protectors have holes in them where the sensors are located. There's a light sensor to adjust the screen brightness, and the proximity sensor which turns off the screen when the phone is next to your face on a call. You can't see them by looking at the phone alone, but they're there at the top of the phone screen, near the speaker.

red light when in a call (weird)

there is a weird (faint) red light when I'm in a call, anyone know what this is??
(when I take a picture of it using my sensation camera it looks very bright but in real life it is faint like you wouldnt notice it until you look closer)
its there whether screen is on or off, and and if i put my hand over it it just stays lit
is it infrared or something to detect when my ear is near the screen??
My understanding is that is the sensor that tell the phone if your head is next to it or not.
As above, its the proximity sensor for turning the screen off when your face is near the phone.
There are loads of threads on Crackberry about it as their sensor flashes quite noticeably.

Light sensor problem, low lux-value.

My buttons backlights are allways on and my screen in always brighter. I tested the light sensor with my g-friends htc one x, and my lux value was lower i got 160-225 in a bright room while she get 320 and her htc one x is very light sensitive to.
And i get very yellowish picture to using flash in dark areas, could it be the sensor to?
Can i calibrate the sensor, or another faulty hardware from HTC?
No one with same problem or solution?

Screen Too Dim on Auto

The screen is excellent. It makes it hard to look at my Galaxy Note 3 after using my tablet. Only complaint is the automatic brightness is too dim.
Try the popular app Lux as a replacement.

Thanks! Million times better. I don't know how Samsung can't get it right.

Samsung sux on auto brightness, I leave it the middle
I agree about auto being too dim.
May try Lux.
Its also easy to edit Autobright in a custom ROM too, which I may also do
I just tried Lux and it works great! $4.00 well spent!
Lux is just part of the solution for me. The app has an excellent debug feature to watch the raw sensor data. Using this feature I can see that the sensor data itself has a problem.
Steps to reproduce:
- put tablet in direct sunlight or under a bright lamp
- start the debug readout of the brightness sensor
- cover the sensor by hand (sensor is situated top-right from the G in Samsung)
- observe the reading on the screen: it is something below 10.0 for me
- move the hand away from the screen very slowly but still covering the sensor from direct light: the sensor reading increases gradually to values around 100 to 200. It is easily possible to achieve any value up to here by just varying the position of the hand.
- when the sensor readout reaches a value above 250, I can observe a jump to values above 6000. There is no way to cover the sensor carefully to reach any value in between 250 and 6000. The readout just jumps between these two extremes.
- if you decrease the intensity of the ambient light (e.g. by turning down the sun...) you can achieve values as low as 1000 or 2000. But there is always this huge step bewteen 250 and the higher value.
I oberserved exactly the same behaviour with the stock ROM and with the CM ROM from crpalmer.
If there is a way to change the sensor readout, that would be great. I cannot imagine that it is an inherent property of the physical sensor. If so it is just badly engineered
I'll check out the Lux app, but thought I'd pipe in with my 2 cents (although its probably worth $0.00)...
I noticed sensitivity to shadows with Samsung's auto brightness on my S3 when using an Otterbox Commuter case. If the case cast a little shadow from the lip, the screen would go very dim in bright conditions. My Tab Pro 8.4 seems to have similar sensitivity issues with shadows. I often use the tablet at my desk, with a soft white ceiling light behind me and an overhead desk lamp turned off (unless I am doing paperwork). If the tablet's light sensor catches my shadow from the ceiling light without my overhead light on, the screen goes very dim. If I reposition it with the sensor outside of my shadow, it is perfect for me. It is an annoyance though. Once my Seidio case gets here, I wonder if it will be more of an issue.

Capacitive Buttons dimming?

I've had my White / Silver HTC One for a few days now and it was bought directly from HTC UK.
I really like the phone but I've noticed that the back and recent keys don't light up as bright as when I first used the phone. Over the course of the week the buttons are getting dimmer.
Has anyone else noticed or have this issue?
I noticed that with my phone too...until I found out the buttons vary brightness with the ambient light just like the screen does. When the screen is dim the buttons will be dim and when the screen is bright the buttons will be bright.

Camera dual-led flash

Hi all. There are 2 LEDs, but when flashlight is on, only one (on the top) is active. I thought the second one can be activated when camera is used, but no, it does not help. Any ideas on how and when it should be active? Can someone check this on your device so that I can know whether it is a hardware issue with my phone? Thanks in advance!
It seems that's a kind of light sensor, or infrared led - because it even doesn't shine when I apply external 365nm UV light source.
It's the second light sensor which measures light coming from the back side of the phone. When you shine a strong light directly on this sensor, screen brightness bumps up after a while. It doesn't happen if you cover the sensor by finger. The purpose is to have screen readable when you're holding the phone against bright background (window, TV screen...) and in my experience it's quite a nice feature.
