[Q] Auto Brightness

Just wondering if the auto brightness on the HOX is worth using ?
I have found on other hand sets apart from the Iphone that it ends up using more battery.
So just a basic question do you use auto brightness and if not what sort of level do you have brightness set at ?

hmm, now that you mention it. Putting it on auto actually may draw more power since it always has to adjust itself depending on the light in the environment your located in. I used auto all the time and I get HORRIBLE battery life, cant even get through half a day so I put it on around 40% or so now. I put it between the C and the B in the Automatic Brightness text and I use medium font size. That should be around 40%. Going to report back later to see if it saves battery or not.

Well I have been using around 40% myself for a while now but was reading somewhere that auto brightness is better but I wasn't sure how accurate that information is.
Does the font size have anything to do with battery life ? I have it set to small at the moment.

Auto brightness only works if they do it right, which is to say that it properly sets brightness for a given situation. (100% outside, 0% in darkness, and properly scale between the two extremes)

Yes but on this device is it worth using will it save you more battery life then just say manually setting it at say 40%

For Auto Brightness i use the App "Display Brightness" from Market .

Auto brightness actually saves battery. I lose battery even faster than usual when setting costum brightness even when it's way lower than 50%

Really? I guess I'll do some testing do you notice a major difference? Cause setting the brightness myself I keep having to change it for when outside cause if to sunny can't see screen properly

I recommend using auto brightness. It really does save juice unless you put the screen on really really low brightness I guess but that sucks because you can't see the screen

Autobrightness bug

Hello little birdies.
I am having an issue with my auto-brightness and I would like to know if anyone else has experienced this.
Whenever my auto-brightness shines through the power of the sun (goes to 100%) it seems to get stuck at full brightness and my already not so good screen-on time takes a dip and I always notice this too late . I use the quick settings widget which is preinstalled and the A for auto-brightness is set but when I click it the screen immediately lowers the brightness, while the A for auto-brightness remains, and a vain in my forehead pops.
Furthermore after checking badass battery monitor it shows that my screen is often at 100% sun shadowing brightness. Today it was at full mutated power the whole time. Anyone got an idea as to what could cause this? Anyone?
PS. You might have noticed in the text above that I think the screen is really bright when at full power and that I can see the screen perfectly during a warm ball-soothing sunny day.

Yes, I have a bug with auto brightness too. It seems to deactivate itself. I have activated it a couple of times and everytime it deactivate itself at 100 % after some use.
I have an international HTC One X with the latest 1.29.401.11 update.

Glad to know I'm not the only one. I will soon factory reset my phone to check if it magically gets better.

I noticed this last night. My phone was blindingly bright and I didn't understand why it was set to 100%. I set it back to Auto and so far its still on Auto. i will have to keep an eye on this.
HTC really need to fire the monkeys they have working as coders. I guess if their software is not fixed up in next couple of weeks there might be a whole lot of people, me included, who will migrate to the SIII (given of course that it doesn't have a gazillion bugs as well).

I've been trying all day to recreate the problem but ist not doing it. I put my phone in the sun, I tried using the camera app, I used the video app with its 100% brightness setting, but the phone is still showing Auto brightness.
Any ideas on what triggers 100% brightness?

I have the same problem with mine. It's just randomly turns off auto brightness

I don't know either what triggers it. It seems to deactivate at either 0 % or 100 %.
I don't have many apps installed, if I just do some web surfing and put it to sleep, when I wake it up the auto brightness is deactivated, in maybe 1 of 4 times. Irritating.

For whatever reason i haven't been getting the auto brightness bug for the past three days. Not sure how it resolved itself since I didn't get any software updates.

If you watch a video you can change the brightness and will stick and not go back to your original settings.

No, that's not the trigger. I investigated that on my phone and found no link.

I take that back. You are right! It seems the brightness setting in the movie play is the culprit. Although it doesn't always do it. One more thing for the chimps at HTC to fix.

Yesterday the auto brightness bug kicked in right before my eyes. I was browsing the web in total darkness in bed, when suddenly I was blinded by 100% brightness. So it's not just the movie player brightness that causes this issue.

Just got the autbrightness bug with the camera app. Everything seems to ****ing set it off now.. :banghead:
Sent from my HTC One X using XDA

Yeah. That's because the camera jacks up brightness for outdoor visibility. They need to have an option to disable that.

I realize that, however it doesn't always do it. Also sometimes it will kick into 100% brightness without using the camera or movie player. It seems completely random to me.

mine is stuck at zero. started this morning and I did record a video actually.
auto just takes it.to zero.
but also, if i change it directly from the srttings menu, its not.effecting at all, just staying at the same previous custom level.
whrn using widget, just turns it to zero.
opened the video player, changed brightness level and its normal now. it was in the middle, the video brightness level
ok just edited this post and its malfunctioning again.. arrrgh!

Try an application that controls autobrightness, it should fix the problem. I would recommend Lux Dash.

So it is the widget, powertoggle.
Once I fix the issue by changing video brightness, it works fone, till I toggle the widget to use auto-brightness.
Several comments on PlayStore also confirms this with several phones.
Just don't use auto brightness from powertoggle. It is actually doffetent.from what OP describes, but.people may come up to this thread while searching, so I think it willbe useful to post here.

Auto brightness issue
I too had the same issue, i tried to resolve the problem with htc but unfortunately they said that it is a software but and we need to wait for an update....

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.

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
Hi,
I have an issue were I can´t dim the brightness at all!
Killing my eyes!
Any solution?

With last 3.5.2 is been solved

Light sensor issue?

I was thoroughly unimpressed with the auto brightness on my unit so I kept it off. Every time I tried to use it, it would immediately drop to like 10% brightness in all but the brightest conditions. I consider the stock auto brightness unusable.
After getting tired of manually adjusting it all day I installed lux auto brightness on my phone and started fiddling with it.
It's better now but this isn't a permanent solution as the developer abandoned his app over a year ago. It's causing a few issues allready and apparently it's completely incompatible with Oreo.
While playing with the settings, I noticed that the lux readings were much lower than I expected. I was getting 20 lux in a brightly lit room, 50-75 lux facing the window, etc. Occasionally I would see it jump up to 20,000 lux in direct sunlight but then it would just dip back down to sub 200.
I obviously have some issues with my light sensor and am going to contact OnePlus to RMA my unit. I'm just curious how many more people are affected by this or if it's a fluke.

I also keep auto brightness off. Agree it's unusable, makes the screen very dark.

I thought it was just me. Auto brightness seems to favour the more dim side, it can get very annoying.
I hope when LOS/AOSP ROMs start showing up, they'll be able to fix this as it does seem like more of a software thing

I actually had the opposite issue where it would get way too bright in a dark room randomly. They really do need to tweak the software around this.

I just wish there was a good alternative to lux. I used to install it on all my phones and all my friends phones.
Nothing else available comes anywhere close to being as good as lux.

Using Lux and no issues as of yet tbh...

I use Velis auto brightness. Works well on 5T

Uninstalled lux as it broke face unlock and the camera. Both simply stopped working.
Trying velis now.
