[Q] Auto-brightness too dim?!

I noticed after playing a bit with my TF that the auto-brightness is a bit too dim than what I'd like. Definitely not nearly as bright as my EVO, iPad, or Nook Color. I ended up setting it fixed at half brightness. Anyone else agree/disagree?

I agree, it's a bit on the dark side but its not too bad.

Autobrightness is calibrated poorly on pretty much every device unfortunately, I'd guess the Transformer isn't all that different.

I think the TF's screen is just dimmer as a whole (this is compared to my iPad 2). I don't mind it when doing things like surfing and email, etc. It only bothers me when I'm watching a movie because I have it set to about 90% brightness, which is pretty much even with my iPad 2 set at 60%, and the light bleeding is more apparent on the TF when set to that (this also makes the little home task bar buttons on the stock movie player more apparent as well. Why can't there be a movie player that just shows the movie and nothing else?)
I guess it makes sense though since the TF screen is bigger than the iPad 2's. Like in TV's; the smaller the screen, the brighter and better contrast they'll be.

I saw this also. I have auto brightness turned off and have it 1 click before max brightness.
I wonder if it could be dirt or grime covering the sensor next to the camera?

I agree. I don't know why they don't let user pick the initial brigtness and based on that, adjust the lighting. It seems like an easy thing to do.

I thought it never went below the value you set it at just prior to turning on AUTO.
IE- If you have it set at 50% and turning on auto it'll never go below the 50% mark.
I haven't messed about with auto since my first firmware so maybe they changed this in later ones.

I'm pretty sure it's reverse, as in you set the bar to the highest setting you want and it adjusts to the room settings without exceeding the highest point you set. That's how it works in my iPad 2 at least.
Edit: This is, indeed, how it works on the TF

Not true. I just set mine to the lowest setting, then turned on the auto. It still brightens when there is light present.

If you start testing with auto brightness, one thing that you need to be aware of that makes it hard to test is that the TF checks to see if it should increase brightness frequently, but it only checks to reduces brightness after the screen goes to sleep or a power off. So once it is bright it seems to stay that way.

I stand corrected. Looks like Auto, truly is, auto no matter where you set your point in the bar. I just set it on the highest and then hit auto and went into a darker part of the room and it did dim the screen down, and I did the reverse like you did and it adjusted brighter in a higher lit part of the room.

I don't know if that is true, because if that was the case, it should be brighter most times. and less likely to dim, but I'm having the opposite effect.

So what's the final verdict. Will AB limit itself to whatever manual brightness you had set as the max or min?

From the testing I did, AB bypasses any setting you put on the bar and just adjusts to room light conditions.

I just bought a B60 serial TF and it has the dim auto brightness issue too.

I have also experienced this dimmer than what I want the brightness to be when I set to auto issue. So I revert back to the default brightness setting that came with Android 3.1. Much better on my eyes.

Lower brightness settings?

Greetings everyone I would like to know if its possible to modify a value to enable a brightness setting lower than 25% as a minimum?
I ask this because if I am in a pitch black room and turn on the phone even the minimum brightness setting is enough to blind me
Do these settings reside in the from or kernel?
Thanks

Check out "Screen Filter" (by Haxor Industry) in the PlayStore (Market)

Thanks il check it out but it would be neat if the rom can do that since it relies on the light sensor to adjust the power of the screen it would be cool if the auto setting was able to read from a lower value than 25%

Gsam has an app that might be to your liking. on my kindle it can drop the brightness to below the minimum level. Search Gsam in the play store and then scroll to "other aps by:".

Screen filter is good. Lux if you want to set some manual points for brightness but I'm not sure if the sensor will limit your ability to distinguish from pitch black and dim since the phone itself will emit light in pitch black. Worth a shot though.

I am currently using screen filter and it works pretty good I don't go blind at night trying to read my phone its just that I have to remember to turn it on I tried the app by gsam but even at .5% the screen is still very bright so far screen filter does the job

There's a new app out there (XDA story on it today) called Galactic Night that's designed specifically for ultra-low-light settings. It's also in the Play Store now. It says it works with Galaxy S2 "devices" running GB and ICS. Not sure if that includes the Skyrocket, but no harm in asking the dev if it's what you're looking for.

Very aggressive auto brightness

I have the brightness turned almost all the way down then I turn it on auto. Is this the correct way to set it? It seems very bright even set so low.

It definitely is too bright, i agree. I'm just putting together a nice setup for the Lux app, and hope that Google will make it a little less aggressive and therefor more battery-friendly

I noticed this as well. I just turned it down and left it (no auto).

They were outside in California during the summer in the day and in an overly bright and cheerful Google headquarters during the night. They forget not everywhere has retina burning light levels

I've noticed that iOS, Touchwiz and a few other vendor Android skins implement a sliding-scale auto-brightness: You can enable auto, but also slide the overall average brightness up and down. This is a simple solution for varying comfort levels: Brightness fiends can tune the auto higher and those with sensitive eyes can tune it lower. I am surprised stock Android has yet to implement this.

I found auto brightness to be a bit erratic. I'm sticking with manual brightness.

Here are my lux settings. At very bright areas you might have to add a few steps but it works well for me in darker, dimmer areas

Edit: Sorry it apparently wasn't publicly available, but it is now

Have any of you had your brightness fluctuate from higher to lower? I don't remember the n4 doing that only. I thought android only went from low to high.

I actually want the opposite. I set my brightness all the way high in manual but I hate that automatic dimming. Can I get that fix? All I want is to work like my HTC One where I set the brightness all the way high and never saw the screen dim itself automatically. Please help

Yeah, and i hate that. I am not battery crazy like some other users, all i want is a bright screen regardless what time of the day it is. 100% brightness all the time. Can Auto brightness be turned off? Otherwise, and I hate to say it, but will going back to the One until this gets fixed.

auto brightness is terrible
the screen become yellow and green look while the brightness is low
only 100% can present the true white color
compare with htc one, i think one is better performance
anyone get the yellow tint problem?

+1 for Lux. I had the battery-guzzling HTC Amaze ("you'll be AMAZED how fast your phone dies!" ). Lux would almost double my battery life when I programmed it with ultra-conservative (but still usable) settings.
If Google will update the auto brightness calibration everyone will start seeing much better battery life.

I use this one:

The trick is in setting up the profiles by hand, the automatic profile settings can be wonky.
Take some light measurements in dimmes light and establish the lowest level you can accept the screen. On an N5 this is probably all the way min. (At first you may find that it's pretty dim but Realize that you'll get used to this and later wonder why you liked the screen so bright.)
Then go into bright light and find the min level that you can accept. This might be all the way bright (on my Amaze, all the way bright was unnecessarily bright EVEN IN SUNLIGHT).
Then take a reading in a normal room and find the min acceptable brightness. This may still be all the way min.
You may want to sample a point or two in other light levels, usually 3-5 samples is enough if you suss out the power curve correctly.
Everyone loves iPhone battery life... ever notice how conservative an iPhone's auto brightness setting is? I'll go out on a limb and guess that, if the N5 is as aggressively bright in auto mode as everyone says (don't have mine yet), there's the possibility of getting an entire extra hour of SOT just by switching instead to very conservative auto-brightness settings.
Also if the min brightness is still pretty darn bright, there's a really good chance an update can knock that brightness down and stretch the battery even further.

Adaptive Brightness

I think I've gotten too used to this feature on my old Note 4 with CyanogenMod, because I really miss it on my V20.
I just got the phone today, and so far, I really enjoy using it. But I'm having trouble with the lack of adaptive brightness. I like to have my phone screen dark (dark themes, low brightness, etc), battery saving or not. With adaptive brightness, I could set the brightness slider pretty low, and still have automatic adjustments; the screen would just be darker in brighter light than it would be on a higher setting.
It looks like LG got rid of this and put the old auto brightness back. I know most people prefer this, but I do not. The screen is just too bright for me. Is there any way to get adaptive brightness on here, preferably without root?

It looks like Lux is the only option. I've used it before and never really enjoyed it. I installed it anyway but brightness is really jumpy. I guess I have to hope T-Mobile adds it back in.

You need to adjust the settings. You can tell the app how quickly/slowly to ramp up/down the brightness. How much of a change in brightness is required before the change is actually made (so the screen isn't jumping around by 1% every time you move it in your hand). You can set brightness levels for certain ambient light levels, all to your choosing. It takes a little bit of time to dial it in, but it's far better than the garbage auto-brightness LG uses. I too miss the built-in adaptive brightness.

Outdoor visibility (max brightness)

Rate this thread to express how well you can see the OnePlus 6T's display outdoors. In case you've been playing Minecraft for 18 months straight, you might not known how to get outside anymore. Well, find the door and walk through it. A higher rating indicates that it has very high maximum brightness and thus fantastic outdoor visibility in direct sunlight.
Then, drop a comment if you have anything to add!

Ok well here I go, I see a ton of views in this section but no comments.
First of all, I'm coming from a Moto Z2 Play and a OnePlus 3T:
The screen brightness of the OnePlus 6T is the major letdown I ever had, it is miserable, sad, despicable... Here is the deal, if I set the screen to 100% brightness in the O6T, it equals to anywhere around 85% or less of the max brightness in my 1 year old Moto Z2 Play !! also, the OnePlus 3T is brighter than the O6T by a tiny notch, but I have to add that my OnePlus 3T is 2 years old and noticeably lost its max brightness, but it still beats the O6T!!!!
If you are wondering about my device, I went to 2 T-mobile stores in the area and compared brightness, they are the same as my unit, so it is safe to say that the O6T is a disappointing device when it comes to screen brightness...
I will edit this post if I get more info or if I need to correct something.

Does the Oneplus 6T support a HDR10 display?
I had the Xiaomi Mi8 Pro and that did.

Looks good on maximum brightness, or very close to it, but anything else looks quite dim.

I must say that the screen is quite dim. I have to keep the phone at 65% or more while indoors to get good visibility from the phone. Not sure what that's about, but highly disappointed.

i found the built in ambient brightness kept setting a little dark and was slow to react to going out into sunlight. switched to velis auto brightness and it is fine now.

thanks for the comments. Was comparing this phone to a couple of others for a blackfriday purchase. Sounds like this one is hard to view outside.

I have zero issues with mine in direct sunlight.

I had to get ElementalX's HBM app to uncover the hidden 40%+ brightness of the screen.

I find the screen itself bright enough. Just the auto brightness is a bit aggressive and can set it too low

But the auto brightness is learning!
It was constantly to low on my phone too. But I dragged it higher every time it was to low. After 1 week of annoying adjusting, it's working fine now!

For those who complains that they have to dial up the brightness slider:
I was like you too, complaining about the auto brightness. However, it has now changed to "adaptive brightness", meaning it learns from your preference. Just turn it on and manually adjust when the auto adjustment doesn't suit you, after a week or two it will get better thanks to machine learning in the system that will learn your preferences.
Also, I remember reading somewhere that the brightness slider now adjusts the brightness in a logarithmic scale instead of linear on older versions of Android.
You can read more about adaptive brightness from an article by Android Authority:
https://www.androidauthority.com/android-pie-adaptive-brightness-927080/
(Also if you are interested, and geeky enough , you can read this excellent article on Android Pie's logarithmic brightness curve here: https://medium.com/@Tunji_D/reverse...ies-logarithmic-brightness-curve-ecd41739d7a2)

The screen brightness is great indoors but not bright enough (even with auto brightness off and on the max setting) for use outside on a sunny day.
Anyone who says otherwise isn't being honest with themselves, with us or possibly both.

Ha! I wondered why I was so much less annoyed with the auto brightness in the last couple of weeks. Thanks for the tip!
Gotta say, have loved the battery life. I like my screen bright and for a while it forced me to behave.

Nothing's fancy with the settings, I think I just made it auto (I believe everything's is by defaults)
