Hello,
Did any of you notice the phone auto switching the screen brightness when using it even though you don't move an inch and the room light is the same? For me it seems that sometimes it boosts / dims the display for a few seconds just to come back to the value it was before ... and this is annoying
Thanks!
The light sensor of this phone is on the upper left (near the left side of the earpiece).
If you are using a screen protector that may be covering that area, then you might have some issues with auto brightness.

Hi,
According the the literature the light sensor adjusts the backlight according the the ambient light available.
Is it just me but this doesn't seem to be working and yes 'Auto adjust backlight' is checked.
Regards.
I can actively see this working all the time, if you happen to hold your hand over a bit of the screen you'll notice it slightly fade. I'ts not a major difference but it's def there.

On my TD2 it is working, but the change in backlight are not so obvious, you have to pay attention to see it: the change is not instantaneous, it is gradual (over a 0.5s time maybe), and it does not change much (not as much as the powersaving no-activity backlight level, which is much lower).
The best way I have found to check if it work is to be in a moderately lit room, and cover/nucover the light sensor with your finger. You should be able to notice the small change in backlight level as you cover/uncover the sensor....
BTW, anyone knows if it is possible to tune the backlight level/ ambiant light function? I would like to keep the auto-adjust, but lower the backlight level when it is completely dark to the minimal setting (or even lower), similar to the powersaving level I was talking about above.
This very low level is not nice for watching movies or pictures (it skew the color rendering because white is not white anymore, it is yellowish grey), but I find it ideal for ebook reading in the dark (it saes the battery, it is not tiring for the eye, and it is not bothering for the sleeping beauty sharing my bed when I read late ;-) )

When I move around (indoor/outdoor), the screen brightness is very consistant (and colors are brilliant too), I persume the light sensor worked
but TD2 did not respond to my random playing of the sensor.. the finger trick did not work for me, but i don't care

Maybe a stupid question...but maybe you mistake the LED for the light sensor.
The indicator led is on the left of the speaker grid, the light sensor on the right...if you have ticked automatic in the backlight intensity (parameter/more/alimentatation section, backlight subsection), you should definitely see a change if you are under bright light and cover/uncover the light sensor just right of the speaker grid.
BTW, thanks fort the g-light application, it is working nicely!
Could even save battery, although maybe this is mitigated by having one more background process running for polling the light sensor data...
HTC's website says the HD7 has an "Ambient light sensor".
When I have the Brightness settings on "Automatically adjust", I do not see any changes to the screen brightness. Darkness and sunlight have no effect. Curious to know if others are having the same problem or if my phone is faulty.
Thanks
If I set mine to Automatically Adjust on either low/medium or high settings it does adjust according to ambient lighting.
Have tested by holding up to a light bulb on all 3 settings and have noticed the changes.
Thanks for your reply.
A bit more experimenting with a LED torch and it does seem to be working. The curve is not as I would like though. I would prefer the screen darker in darkness and brighter in the light much like my old iPhone. I was in full sun today and the screen still wasn’t full brightness. So with it on High and Auto off, the screen was brighter than when on High and Auto on. So Auto was bringing my brightness down to what seemed to be about medium levels making the screen a bit of a pain to see. I want full brightness in sunlight please. I am sure others will prefer this default setting though, especially those concerned about battery life. Hopefully a future software tweak will allow sensitivity and brightness curve adjustments. Until then, I will stick with the "high" setting and Auto off.
Thanks again.
Have same problem.. Automatic light have no effect on my HTC HD7 (unbranded, with and without nodo).
I totally agree, with me its more of a problem in the darkness. It is way too high when it is completely dark and its more obvious when I switch it from auto to "low" as the screen does become much darker.
Its something with either HTC or windows as my old touch pro 2 had the same problem, in complete darkness the screen would never go lower than 30%...
The light sensor on my hd7 never seems to work..they should implement the way it is on the iphone

Is anybody know is there light sensor available physical on HD7?
Heared on HD2 it work's fine. If it software issue then MS mast fix it.
yea my phones ambient light sensor doesnt work either i see no changes with the auto setting on.
Auto-Brightness works fine over over here - o2 debranded with NoDo update.
When i take the phone out of my pocket/case in sunlight, i notice about 2 - 3 seconds after I unlock it, it gets noticeably brighter and when comparing to "high" brightness without auto it's exactly the saem. Agreed though i would like it to be dimmer in complete darkness (in bed, for example).
I am curious if there is a registry entry that I can change to help with the highest and lowest settings. If I turn on auto it does adjust it slightly when I am inside, but when I am in the sunlight I can hardly see anything. If there is no light also it is still what looks like a medium setting making it very bright. I hope we can figure this out, it isn't a big deal but still BTW I am on TMOUS with NODO
Hey guys,
I just realized both the light sensor in the upper right hand corner AND the camera have an effect on the screen brightness! It seems that the one that reads a higher lux value is the one that's used.
I downloaded "Sensor Dump" and you can watch the values go down after you cover the light sensor. After you cover it, try keeping it covered but pointing the camera to something bright, and the values go back up!
Cool!
My concern is it only seems to detect 5 levels of light. And it's the same in different sensor apps.
The levels are
10 lux
33 lux
333 lux
1400 lux
5316 lux
Same 5 levels here. Same camera/sensor
also this answers my annoyance with switchpro widget (or anything that triggers the LED flash) - when the flash is turned on -> the light sensor doesn't return any data.
The screen will dim and brighten randomly while i walking or using the phone. Is this an bug or its it my phone sensor spoil? I am using official firmware V10D
the same thing is happening on my phone. help please is very frustrating .
The same thing happens to me and actually it is very frustrating.

I thought that was the Idea of Auto brightness
The screen brighness changes depending on the Ambient light level in your surroundings
You could try cleaning the screen around the top left corner where the Light sensor is and see if that makes any difference
Try to hold over the sensor for >10 sec and see if it still fluctuates. If not, the sensor is fine and the light hitting the sensor is changing, as waynefox writes.
It is also possible to turn off the auto light for the display
Go to settings-->display-->brightness, and un-tick the automatic brightness
Hello, I would like to know whether other people see the same like I see.
The lower area, around the fingerprint scanner is a bit more blue than
the rest of the display (which is slightly yellow at automatic contrast).
This gets mainly visible with low brightness and
disappears with max brightness.
Is this just my unit or do you see something similar?
