Hello!
Do you also suffer from the dumb eye care / low blue light filter on the Tab S8 with LCD?
Ist there any option out there with root to change the LCD calibration and reduce the blue color channel?
Or to enable the stock android night light mode?

Welcome to XDA
Don't go too nuts over blue light. I don't use night mode anymore on my N10+, the color rendering degradation is annoying.
Increase room ambient light levels and manually adjust brightness to the minimum level needed instead.
Take a break every few minutes to look at a distance object.
You will adjust to the low blue light mode and forget about the orange tint if you enable it for all your devices Android, Windows, ... And the low blue light mode really helps to relax the eyes.
For my liking the Tab S8 LCD color temperature is far too cold. And there is no way to adjust it like you can do on the S22 in the display settings (even with no blue light filter enabled).
The low blue light mode on the S22 and Windows behaves identical and they can be adjusted to match. You won't loose by far so much image quality like on the Tab S7/8.
The correct way is to adjust the color channel equalizer of the display/gpu and not putting a transparent orange overlay on top of everything.
This stupid orange overlay is by far not the same like the real low blue light mode.
Even if you enable it at 75% the whites are still not warm and the blacks get brown so that there is no contrast left.
And at 25% you won't notice that it is enabled but also dulls the image.

Yeap.
Again I wouldn't even bother with trying to pursue this... results will be predictably suboptimal.

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
hi, so i noticed its has TWO leds that shine up but its not pure white light, its like an amber color. imo its not bright enough...is there a mod or hack to brighten it up? thx

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.
Hello,
I'm new to Huawei and one thing I noticed about my P10 is the very faint notification light. From a little distance it is very hard to notice.
I've tried installing Lights Manager, but changing the brightness there doesn't seem to do anything.
Does anyone have a way of increasing the brightness of the notification light on the P10?
Thx
I just got the phone and Yes my notification LED is SO DIM AND USELESS. I tried to use light manager and seems like the brightness is already the highest. Will pop by the shop in the weekend to see if it's my set problem or all sets are like that.

Mine is faint too. Or at least I find it that way coming from Sony Xperia phones where the notification LED was very bright and you can see it even on sunlight... Sony also used different colors for different notifications - here is green only unfortunately... Hope Huawei fix this in some future updates....

Hi all,
actually it has colors too. On Whatsapp, if you choose white or blue the notification light will change to that color. Problem is that there is no way to configure light colors for the rest of notifications, unless you install some notification light management app which I had once in a previous phone.
About the intensity, yes, it's a bit faint. But, personally I prefer it against Samsungs that I owned previously in which notification lights were so bright that at nights it illuminated my room when sleeping (and if it blinked, even worse!).

useless tiny notification on LED. This is factory dumb design.
I actually like the brightness. Coming from a N5 where the LED was brightening up the whole room when someone sent you a message at night, the p10s subtle notification is much better.
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?
