The N10 auto-brightness feature doesn't work right, as everyone knows. It randomly dims and brightens in an annoying way. I'd read it was a software issue - something to do with JB 4.2 - so I tried two different auto-brightness apps from Google Play, both of which get good ratings, and to my surprise I had the same problem with both of them. When the brightness depends on my N10's light sensor, the screen keeps dimming and brightening randomly. The app I have installed (but disabled) now is "Custom Auto Brightness". I wish I could use it because it looks very good.
The fact that the problem appears regardless of the software suggests to me that the problem is in the hardware - there's something wrong with the data put out by the light sensor. Does anyone have any info or insight about this? A workaround would be so nice.

does anyone else get an issue that the G2's backlight for the physical keyboard and capacative buttons have absolutly no idea when to be on and when to be off. I can be in a fully lit room and have the backlight on for no reason at all. is there any way to fix this? it gets very annoying very quickly.
It's a problem with the light sensor, but I think it can be corrected with software. The sensor seems to reflect differences in brightness really well, but the software tends to set everything to levels appropriate for brighter conditions. This leads to full screen brightness and no key backlighting even under dim interior lighting conditions.
my screen is SUPER Bright regardless of ambient light (in automode) I rely on the manual settings.
and yes I do have the same problem ... even on my second g2.
Same here. My backlight and softkeys go on and off randomly while in bright light and checking the time while waking up briefly during the night is painful because it is always extra bright.

thanks swags. hoping for a software update soon. its really annoying. also is it normal that i get this issue even without auto brightness
Hi, started this thread to see if anyone had the same problem I'm having with my screen.
I have a Galaxy S4 GT-I9500 (Octa-core variation), it is running 4.4.2, rooted, stock Touchwiz.
The problem is that the screen starts to flicker almost as if it would want to turn off, when in low light conditions and auto-brightness on, it continues to flicker unless I set the brightness between +2 and +5. I can reproduce the issue without auto-brightness setting the brightness to the lowest, one notch above the lowest and there is no flickering. It is noticeable in white backgrounds and also when swiping down the notification center, that's the most noticeable instance but you can see it in the home screen and in any app.
I started noticing it when I had 4.2.2 Jelly bean (rooted), and I updated to Kitkat hoping it would be solved but it is the same, I updated through Kies and rooted, no Factory reset, I want to try that as last resort.
Funny thing I discovered is when I set Juice Defender to control my brightness it does not flicker even in -60% brightness, but when the dimming happens before the screen turns off it does flicker (and the dimming thing is controlled by the OS I think, not Juice Defender).
I wish I could put up a video but I don't have another phone to film it.
Anyone know if this is software or hardware? What can I do?
I'd like to add, that I changed the battery, disabled overlays in developers option, forced GPU rendering, tried Pimp my rom and played with all the settings, checked and unchecked every option in Display settings and it still flickered given the low brightness conditions.
I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...
Hello to all,
I have a strange behavior with my auto brightness. It sometimes will slightly increase then decrease again quite quickly. This happens not all of the time but regularly. It even happens in dark conditions without any varying lighting conditions that could cause this.
My phone has already been reset a number of times so am wondering if it is software related or hardware related.
Anyone else notice this?
It's a known issue (known by us, not ZTE, apparently). I believe the light sensor reads the light from the screen itself, bouncing on you, then corrects for that, the light changes accordingly and it starts over again

Thanks for that. It could indeed explain it.

I picked an Axon 7 up today and I too notice strange behaviour by the light sensor.
I've tried searching the forums and Google for this issue and I could only find this thread.
Is the issue hardware related? Do you think it could get worse over time? I'd love to read more about these issues but am having trouble finding anything about it.
Edit: symptom is an aggressively jumping auto brightness bar. The brightness is occasionally lowered and raised in rapid succession, even in stable lighting conditions.
EditEdit: I've not updated the phone since I received it. It's on 6.x.x. Could there be a recent update that tackles these issues, or makes them more bearable?
Maybe it's solved by turning off assertive display in settings. I haven't noticed this issue before on mine but a lot of other issues e.g. fingerprint sensor acting weird and giving continuous "finger moved too fast" or "partial fingerprint detected,please try again" errors (but when it works, it works really fast) that most of them were related to software. The stock ROM is quite buggy though. (Mine is Chinese A2017)
I would take a video of this issue, but I don't have a good enough camera. It's really, really hard to capture unless you have good video recording tech, which I don't have. :crying:
My issue is that, when I set the brightness to its lowest level on my Zenfone 3, the screen starts flickering. This is especially noticeable with white backgrounds. You can tell that the screen is flickering (perhaps refreshing?) rapidly and it makes the phone painful to look at.
Someone actually created a thread about this issue here on XDA a few months ago, with a video showing this issue, but unfortunately, the video doesn't capture the flickering properly. Here: https://forum.xda-developers.com/zenfone-3/help/ze520kl-low-screen-light-level-20-t3603502
How to reproduce:
-Turn auto-brightness off
-Slide brightness bar all the way to the left (AKA to the lowest level)
-Open a white background/grayish background or blank page in Chrome
-Screen starts flickering
It happens across the phone, and intermittently. Sometimes it happens, sometimes it doesn't. In Chrome, in games, whatever. I once thought it could be related to charging the phone, but the screen has flickered on low brightness even when my phone wasn't plugged in, and at 70-80% battery. I might try resetting the phone to see if it's a software defect; I really hope it is.
Turning off hardware overlays in Developer Options does not resolve this issue.
I'm currently on ASUS stock Nougat, unrooted. I can't root right now. I don't have any screen overlays apart from CF.Lumen, which isn't set to come on during the day, when the flickering happens, and I don't use any screen color modes apart from the default settings. I also always have auto-brightness turned off.
Just wondering if anyone else is having this issue. I might try recording it one day.
Thanks.
Update 1: Removed my 64GB SD Card from the phone to see if that made a difference. It didn't. So the flickering isn't related to power management, AFAIK.
Next step is to wipe the phone completely, including its cache partition from stock recovery, and set the phone up as new again. It might be a hardware issue, but my fingers are crossed.
I've had this issue since I got the phone, ZE552KL. Turning off auto brightness fixes it for me, so I have a feeling it has more to do with ASUS' auto brightness algorithms than anything else.

I always have auto-brightness turned off. I think it might have to do with the ambient light sensor. I've tested it using SMMI and it works just fine. But I wish there was a way to disable it, since I don't need it. I'm kind of disappointed in this phone.
I'm going to try a full reset, and perhaps a custom ROM to see if it's a hardware or software issue.
Has anyone noticed Display keeps flickering when auto brightness is on. Even if phone is kept at a fixed position & same amount of light is exposed to the sensor it still keeps flickering. I mean if I'm watching movie it automatically dems or increases the brightness. please confirm how many user experiencing this problem! as per i know it was not resolved from 301 to till 331 update. is it manufacturing defect particularly with specific variant ?
I wouldn't call it it a flicker. More like the auto-brightness feature is so badly programmed that it doesn't transition from dim to bright and vice versa in a smooth, gradual or dynamic manner, like in older and cheaper phones.
My eyes get a shock every few seconds, trying to adjust to the sudden jumps in screen brightness. It's a real pain.
And yes, the issue has persisted through all the OTA updates without any sign of improvement.
Instead of addressing this most basic and "glaring" issue, Asus seems to be intent on introducing bloatware and EIS for the phone and announce it like it's the second coming.
The latest update was supposed to bring with it, system optimization but I don't see any form of basic optimization, let alone calibration, with the screwy display.
I can only guess at Asus' sense of priorities. Or if they're actually blind and/or stupid.
May be it was true that autobrightness was programmed badly manner it was not transist smoothly from dim to bright. But afterall we are facing it at serious level and uptill now asus has not solved yet. I just want to confirm that How many user experiencing screen flicker issue after enabling auto brightness or it was particularly manufacturing defect with specific varient.
its an autobrightness calibration issue,software update will fix it in future,lets hope so
Hello everybody! I found a bug: brightness is flickering even when "auto brightness" ("adaptive brightness") is disabled. Brightness can encrease for few seconds and then decrease to previous level. I read in some reviews that max pro m1 has adaptive brightness which changes depending on content on the screen. I tried to change a lot of display settings, developer settings, i tried to adjust CABC (Content Adaptive Brightness Control) through Nova Launcher (but later I read that CABC controls only autobrightness), and even hard reset. I flashed custom ROMs but it didn't help. Only Lux Dash app helps avoid this bug. But it is not very comfort to use it and I think there must be desicion on firmware level. Did anybody has this problem and any solution? May be somebody has this issue and found custom ROM without flickering brightness?
Sorry for my English, it's not my first language. And thank you for answers!
