Light sensor

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...

[Q] light sensor / auto brightness

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

back light notifaction issue

The backlight notification is very dim compared to the vibrant. Does anyone else have.this issue or is there a way to turn of the brightness?

Is the brightness of the phone too dim? Or just the pulldown notification bar?

I think he is talking about the LEDs for the bottom buttons. When you have BLN enabled they turn on with any notification you get. I have seen them be a lot brighter on the Vibrant than on my Captivate.

Have you considered trying NoLED from the Market? Works great!

I have seen some who have allowed the lights to be brighter by removing some of the coating on the inside but this requires disassembly which is not difficult but may be more than you want to attempt. Personally I love the fact that they are dim...the brighter lights attract your eye when in a low light environment.

I can't even look at mine they are so bright. In fact I just looked at them for less than a second and now I see spots as I'm typing this. There might be something wrong with your unit.

Mine aren't bright either. I compared to my N4 and the N4 is clearly brighter, despite having 1 led vs 2. I don't mind the amber tint. It helps take better photos because the color temperature more closely matches the indoor lighting conditions where you're likely to use the flash.

I also feel that the Nexus flashlight isn't as bright as it could be. However, the light on my last phone was similar, and I installed an app that increased the brightness for it. It worked great, but the LED ran much hotter after that.
I suspect that the reasoning for the dimmer flashlight is to not prematurely wear out the LEDs, or degrade their performance when they're needed for camera flash.
When taking photos, the flash output is quite surprising. I don't think it's a hardware issue, rather intentional software programming that runs the flashlight at a dimmer output. As a quick flashlight, I find the N6's lights adequate.

screen not so bright on high

So I noticed that the screen isn't as bright as my Note 4 on high brightness , however when I have it set to auto and I'm outdoors it's night and day difference. It's much brighter under auto, even makes my note 4 (on high) seem like it's on medium brightness . Does anyone else notice this? Anyway to make it bright like this all the time? Because full manual brightness seems like medium brightness compared to other phones. A bit disappointed

That was already discussed in many reviews
Sent from my SM-G900F

Correct.
Manual brightness only goes to something like 450 brightness, but auto can go to 750.
No way to change that. Was mentioned in multiple reviews.

I was at the beach today and everytime I'd look at my screen it would start out really bright and then dim to like 90%. I wouldn't be able to get it bright until I locked it again. It was very annoying.

There is an issue with the auto bright on the Edge. Not sure if it is the same on plain S6 though.

There is? Mine seems to work as I would expect...

Yeah turn auto off and the phone will still dim in dark rooms and bright up if you shine a light into it. Also the Edge does not appear to be as bright at max as the standard S6.
