Auto Screen Brightness Erratic - OnePlus 3 Questions & Answers

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..

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
Sent from my HTC One X using xda premium
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....

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!
True

: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

auto brightness not working good? 3.2.8

so i buy this phone for a very good price, so far all perfect, only little concern is that auto brightness maybe is not working nice
i set auto brightness on, and i reduce the brightness manual for about 1/4
but sometimes i notice that the brightness in screen is almost in max and it shouldn´t be
is this bug?
thank you
I'm rocking the build 9. and sometimes I'm having this issue. but, it's a minor bug i guess.
no one else with this problem? because some guy i know also have this issue
there is any good app that fix auto brightness
Yeah, auto-brightness in OP3 is far from perfect, but at least it's a lot better now than it was in early OOS versions.
You might want to try "Lux" to set your own behavior for auto-brightness, but bear in mind that it take some time for it to "learn" what brightness you want in specific situations. Ofc you'll have to do some manual adjustments during that time.

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.

Question Adaptive brightness

Anyone that has updated to the latest firmware, are you having issues with adaptive brightness? Mine is super sensitive! It's adjusting the brightness within seconds in the same lighting. Something isn't right every since updating mine. I had to turn the setting off.
Mine is a bit low during evening in the house...but at least it remains pretty steady.
Not having that issue.

Updated to .017 and I am still having an adaptive brightness issues being very sporadic jumping up and down when the light is dim.
December update and auto brightness is still ****ty. Worst in any phone I have used. This is so annoying. Maybe Google can just kang the files from Samsung

Can’t believe it’s not better. Thanks for the confirmation. Mine was not as bright as it needed to be but now it jumps like you described.
I just got my Pixel 6 Pro and so far the adaptive brightness has been really good
Mine was really wonky after updating. But after adjusting it a few times throughout the day, it has stabilized and auto-adjusts fine now.
