how well the auto screen brightness works on your device?

After I bought my Mozart for 3months,I have realised that the auto screen brightness function seems like not working on my device at all, no matter under what condition,even in an extremely dark room,the screen brightness is still in very high level,it is painful...especially for my eyes,and it is kind of wasting the battery. Anyone here, experience the same?

Agreed, I have to manully vhange to e.g. high and then turn on autobrigthness then it stays high.

Same here with HD7, have to manually change the brightness.

The brightness on my HD7 does change, but it doesn't change much between bright sunlight and total darkness. It needs to change a lot more than it does.
All we need is a "sensitivity" slider so we can set the degree of change caused by different lighting conditions.

I think someone's a little lost... X10 is an Android device...

lol,maybe he is drunk....
anyway,just hope that there is a solution soon,or maybe this is a bug...it consumes heaps of battery.My mozart with light use, and it just barely last for 1 and a half day.60% of time on standby.

Nobody cares about your X10.

I have an Omnia 7 with NoDo and auto-brightness works fine...

This made my day. lol

Samsung Focus works great. Maybe its an HTC issue.

we're in the same boat. =(

send it in to repair
samsung focus had quite a bit of hardware issues related to screen and I sent it back. Now its flawless
dell venue pro surprisingly hasn't had huge issues

I could be imagining, but it seems to me that if i choose low, then turn on auto adjust, it does auto adjust but is inclined towards darker settings. Conversely when I choose hi and turn on the auto adjust, it adjusts, but is inclined towards brighter settings. Anyone else notice this?

works perfectly on my Samsung Focus. Though i do hate the manual low brightness setting, it is still very bright even when manually set to low. i m guessing thats an issue with all SAMOLEDs.

My Focus is not good at all using Automatic Setting. It's my Second Focus, and same results with both phones. Slow to change, and usually not enough adjustment when it's needed. Like, if I'm in bed with the light off, it does not go to lowest setting. If I do a manual Low setting, it gets dimmer. Same with bright. In very bright sunlight, it never goes to the Top. I need to manually adjust to get it all the way up. I was hoping NoDo would fix it, but it didn't.

Here it is bad.
I got blind every morning. Probably it would be better to look at the sun than look at my phone screen.

Yes, I had my phone next to my spouses. She had hers set to high, then set to auto adjust and I had mine sent to low then auto adjust.
In the same lighting condition my was ligther than hers, and was on the ligther side all around. Conversely, I switched mine to high and hers to low and it was the exact reverse.

So there ARE high, medium, and low auto-adjust ranges... Interesting. Thanks for checking that, I would've had no way to test that. Good to know.

Jellybean Auto Brightness

So this is the issue I'm having and I want to know if its just me or what. On stock jellybean for the Sprint Gnex. When using auto brightness and going into a bright lit room the screen brightness will raise. But when you leave the room it will not lower the screen brightness. It sticks at whatever brightness level is raised too until you lock the screen and then it resets. I have verified the light sensor is reading the lux levels and such. Is this happening on other people phones as well? And if so is there any known fixes for it.

This is happening to me as well. I am running Paranoid Android 2.0 at the moment. I was in bed, completely dark room, and turned the brightness to auto. It stayed at the full brightness setting until i locked and unlocked again.

It does for me.....but takes a few seconds

Did it work properly after that or will it still not dim when leaving a bright room until you lock and unlock.
I have tried holding my finger over the sensor for like a minute and it still wouldn't lower. I'm trying to find a reasonable fix for it. I've read adjusting the levels in the framework apk will fix it but I haven't gotten that to work yet.
Crazy part is. If you use an app to make your own custom levels it starts working. Same thing with cm10 if you use the built in options to set custom levels. But for whatever reason is doesn't want to work on stock for me.

OK. So this is wild and awesome at the same time. I flashes the newest version of rujellin last night. I left auto brightness enabled over night. Woke up today and its working. How crazy is that. As soon as I disabled and enabled it to see if it took. Stopped working again. It has to be in the phone or the code one. When I say code I mean Google code.

I haven't used stock JB, but CM10's auto brightness is great, especially all the advanced settings

It seems to be slowly starting to work. Its crazy. Makes me wonder if some info is getting left behind when I do a full restore to stock. Thanks for the info. I just want to know its not just me.
Sent from my Galaxy Nexus using Tapatalk 2
Edit. I was wrong. It wasn't working that was the screen dimming before it locked. After a some reading and searching xda it seems that this is the default behavior for the auto brightness feature on android. I'm not sure if this is correct or not but the ammount of people saying that versus saying otherwise is greater so Im going to have to agree.

Screen brightness has gone down...

Everything was fine. I had the brightness set to 60%, which was reasonably bright for me. Retrieved the phone from the table to place a call and realized the screen was looking dim. I thought perhaps I'd accidentally turned on Auto Brightness, but I realized it wasn't the case. I restarted the phone, but the problem still persisted. I did a factory reset; still the same. I reflashed the firmware, but saw no resolution to the issue. Incidentally, after the flash and the subsequent setup, I tried to increase the brightness, but the phone refused to permit it, with a message about some heating issue. I was able to do so several seconds later, however, and while there have been no more "heat" warnings, the phone's brightness hasn't been the same. I seem to have lost about 20%: what I had at 60%, I have the same level of brightness now at 80%. And the maximum brightness, on the same token, isn't the same as it was earlier. I'd appreciate any suggestions. If any of you have faced a similar problem and had a found a solution to it, do let me know.

weird ... Guarantee if still possible.

That's pretty encouraging...or is it? Nevertheless, would've appreciated some solution, but it looks like I'm going to have to make that trip to the service centre.

I saw in a review before i bought mine that if it heats up the brightness of the screen is auto. lowered in order to try to keep a resonable temperture. But nothing about your simptoms. Did you try a different kernel here on the forum or to reflash the stock kernel ?

SOLVED

I've an LG Optimus G too.
It can happen two things:
First, the phone takes down the brightness when the temperature is too high, it happen automatically.
Two: Auto brightness is enabled. Then, the phone uses front camera to see how much ambient light are everytime, then it go up and down.
You're talking about the first case, so charge the battery 100% and then unplug it and let them alone for some minutes in order to leave the temperature going down. Then go to setings, screen, and disable smart screen snd auto brightness.
Try it for some time and send us your experience! =D

There is ambient light sensor near proximity sensor,camera is not used for automatic brightness.
He can disable temperature warning with Optimus G Tweaker which can be found in Play Store.
He must be rooted firs,he can do that easily with framaroot app.

Thanks a lot, everybody. Unfortunately, I've sold my OG and moved on to the Nexus 4. I appreciate your responses, nonetheless. Have a good life ahead!

:good: Thats right, in the opposite of the front camera you can find the proximity sensor and the brightness sensor, if you have eye-recognizement enabled in block screen options, then i think it uses the front camera for both things (brightness and eye-reco.).
Near the front camera it only has notification led.
I'm root, but i dont know if someone want to desable temperature warning... it can be... destructive! LoL

How Can You Disable Screen Dimming?

Is there a way to keep the screen from dimming after a period of time? I set it to never turn the screen off while charging, but it still dims while the music app is up when it's charging in the car which is annoying. I can't find the setting anywhere in LG's settings or in tweaksbox.

I tried Lux as others have suggested but it still dims in my truck. Very annoying.

My screen doesn't dim ... did you turn off Auto brightness?
What would cause it to dim by itself? I only run at 61% brightness so maybe I haven't experienced this yet

My auto brightness is off and it still dims. Lux auto is on or off and it still dims.

Yup, I always have auto brightness off. It just dims after a minute or so of no input - which happens while I'm driving. I always keep it at 100% unless I'm in the dark which may be why you haven't noticed it - the screen may dim to around 60% anyways. I find it weird that you can't adjust how long it waits to dim, or turn that feature off. I'm guessing this is part of LG trying to help with battery life.

I've only ran into that a couple times and the screen dimmed to 90-95% and I had to manually turn it back up. This is different where it goes bright again as soon as I touch the screen and the dimming is much darker than 90% - more around the 50% ballpark.

Wow, yeah that sounds extreme...
I know it's a pain, but have you considered doing a hard reset to see if it is indeed setting/software related?

If the OP was referring to the "Screen brightness lowered due to high temperature" message.
Go into the hidden menu by typing 3845#*855# (replace 855 with your devices model number, mine is a D855).
Then scroll down to Thermal Daemon Mitigation OFF and make sure it is enabled (on).
Reboot the device and you can now force maximum brightness all the time.

I actually had to get a second phone a week ago because I cracked my screen (a few hours before my protector came in the mail). At least it was early enough that I got a brand new phone through insurance instead of refurbished, but both phones do it. Could be a Sprint vs Verizon difference - Verizon likes to go crazy with phone mods lol. Though I don't normally run into it with normal usage - only when the screen is set to stay on while charging through the developer option and I'm driving with music.

Mine does that. Sprint phone, happens after a minute of no input, including when the screen is set to stay always on. However, I notice this doesn't happen when running Maps.
I've already gone through two phones, same on both.

There are certain apps - and Maps is definitely one - which will not allow the screen to dim or the device to sleep. (YouTube is another for example, also iHeartRadio, etc.) Really the best thing to do is mod using something like Tasker or Stay Alive! as I mentioned in an earlier post for specific apps. I use mine for the Music app since typically I've got mine on the car charger and dash mount and it makes no sense to go through a whole screen unlocking routine to fully operate music after a while.

Auto Screen Brightness Erratic

Anyone else having this issue? Sometimes in well lit indoor environments, it will be dimmer than I expect and then suddenly ramp up to full brightness.
Likewise in dark environments it will be dim and ramp up suddenly as well.

Yeah, I have that aswell, sometimes it's not perfect at all, I hope there will be some optimizations.

Glad I am not alone. Hope they'll be good with software updates since currently they are known for not being good in that department.

I was really happy to see that option in settings. However I was irritated by how erratic it was. Disabled it.
Even ambient display doesn't work correctly for me everytime. It's kinda random too

To be honest, I think it's partly a Marshmallow issue, as none of my MM phones have had decent auto brightness

I wish I could agree. My Nexus 6 had great auto brightness on L and M. Never had this type of behavior until the OP3.

Might be because OnePlus has implemented their own content adaptive back light like on the OPO. I turned it off by setting a 0 in the file /sys/devices/virtual/graphics/fb0/cabc
Not sure if that file is there on the OP3 but it's worth a shot

I turned it off in the settings and it was fine. I just wish I could have normally functioning auto brightness lol.

I just got my OP3 and have an issue with adaptive brightness, not sure if this is a behaviour that others have seen or if I have a defective device, perhaps someone could advise? My phone is running 3.2.1 and is fully stock, I have adaptive brightness enabled as I always have on whatever phone I use, when I activate the screen or it turns on at the receipt of a notification the brightness is at the approximate level it should be according to the position of the brightness slider and is perfectly usable. After a few minutes, this varies a bit but never more than five minutes, the screen dims to what I think is the lowest brightness level which during the day makes it difficult to see anything on screen. I can get back the previous brightness setting by turning the screen off and then immediately back on but then after a further few minutes it will dim again. The phone is not responding to any change in the ambient lighting as this is always constant and there is no obstruction to the sensor on the front of the phone. I can get a constant brightness level by turning this setting off but it can be a pain having to manually adjust when I go outdoors for example and this isn't the way I like to use my phone. So, is this a hardware fault or just a very poor implementation of adaptive brightness? I'd appreciate any feedback as this is spoiling what is otherwise a great phone.
Thanks

What should we do for this scenario. Should we raise a complaint or wait for an update. I have my phone in warranty. I am sure all of us would have it in warranty.

I've had issues with that feature since day one with my op3. No update has fixed the adaptive brightness issue, and it's the same with all of the custom ROMs I've tried. Has to be an issue with the phone. I'm hoping a software update fixes it because it's an obvious issue. In dark light, my screen dims so much that I can't really read anything on my screen.

Auto brightness is just bad on the OP3.. I've installed Lux to ease some of the problems but I'd like the standard AB to work correctly and not need an additional app..

Can´t dim the brightness at all CM13
