Screen brightness bug - Asus Transformer TF701

Hi.
Are people still having issues with the screen brightness changing itself all the time? These last few weeks I am finding I am needing to toggle smartsave on and off again more then I used too.
Cheers
Richard

Yes, I don't know what ASUS is doing, they should have fixed that issue by now. It is quite irritating to have the brightness change itself when watching movies in a dark room.

Known issue.
A workaround is to install Lux and tell it to set brightness on wake. Works pretty well. (Not as well as a properly functioning ambient light sensor mind you, but bugs like this are par for the course with Asus products!)

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

[Q] Getting Adaptive Brightness to work

Has anyone managed to get Adaptive Brightness to work on their Moto x? I have it switched on yet my phones brightness never seems to change even in near darkness or bright sun shine.
Found the answer here:
http://www.androidpolice.com/2014/0...-is-gone-adaptive-brightness-takes-its-place/
I'm glad you found the answer. I can definitely see the brightness change depending on the ambient light in the room, but it will stick to a more narrow "band" of brightnesses based on how you have the brightness set.

Auto brightness works wrong in the dark

I have my new Note9 on wireless charger in the night. When I get it from the charger and check it the brightness it very high. When I turn automatic brightness off and on then the brightness is decreased to correct value.
Now I created a workaround using Tasker but am I alone with this issue?
I remember that similar issue was on S9 and S8, so is Samsung going to put this bug in each new model?

I have yet to find ANY phone that gets attenuation right.
I've found the Note 9 to do OK when cranking it up for well-lit outdoor use,but,it's a bit too dim on the lower end in the other extreme dark/poorly lit situations.
So,it does seem this bug/feature has continued.
Too bad there's not some some fine-tuning baked-in,say, in dev options, to create your own attenuation from lowest to highest brightness (on all phones).
It worked perfect since I bought the phone in Sept until the latest update in Nov. Now the auto brightness did not auto adjust. Either needed me to toggle the auto brightness to OFF and On again or hit the power button to OFF the display and ON back the display.
I find auto brightness to be a bit to bright in lower lighting conditions.
I came back to samsung note 9 (UK model 128gb 6gb) from oneplus 5T which had great battery optimisation and great auto light adjustment.
Overall the oneplus has better face recognition software (quicker and more accurate and you don't have to look at a very particular distance) the fingerprint (sensor) on the oneplus is also quicker.
Hope samsung resolve the bug.

I am also facing the same issue.
I am also facing the same problem brother when I unlock my phone using iris scanner the brightness increases and then doesn't drop to required level in low light please notify me when you find a solution.
Try...
Settings
Biometrics and security
Face recognition
Brighten screen
Turn it off see if it helps.
(assuming that you are using intelligent scan that could be the issue for the bright at the unlock and taking a bit to go down)

Why is this phone's auto-brightness so utterly useless?

What's going on with this thing? i always have to switch the screen on and off to get it to adjust to the current lighting. Everything about this phone is such a mess.
Do you have adaptive brightness turned on? My snapdragon did not work until I enabled that setting.

It might be a problem with the ambient light sensor on your unit. My S8+ does the same thing, other S8's don't. Get it replaced.
Iam pretty sure its somewhat normal. Auto brightness has never been great on Samsung phones. I realised this when i briefly switched to the Iphone xs. Its auto brightness worked perfectly. I find the adaptive brightness on the S10 plus to be terrible too. Its as if its either too dark or too bright and sometimes it changes without the lighting conditions changing. Its tolerable but its def nowhere near as good as my iphone xs. Its strange because you would think its a feature that would be easy to get right.
work great for me, better than my old S9
I found one issue. I have used a couple of screen savers with clocks on my night stand. They automatically dim the screen. I noticed every time after using them that the auto brightness was too dark. I figured out that since the phone was on auto brightness when the screen savers dimmed the screen, it was being factored into the averages and causing the overall brightness to be lower than I wanted. Now I try to turn off auto brightness before I use the screen savers. I'll probably set up Tasker to do it for me soon.

I've noticed the same thing, on my XS Max I rarely had to adjust the brightness but on the S10 I have to do it quite a bit compared to the XS.

I'm very happy with it. Especially the learning part. I like to usually have the screen dimmer than standard and after a few days it started to do this automatically.
Works like a charm I'd say.
I agree that the S10 does not seem to respond to ambient light well when setting the screen brightness, especially in dark settings. I have a Bixby Routine to set my screen to 10% at night and even then it's still too bright.
