I have a Telus GS4 and noticed a weird issue today, when I hit the youtube app icon my screen flickers briefly just before youtube opens. It is not noticeable when the brightness is set to high but on low it is very noticeable. This is the only app that does this aside from my TD banking app which was doing the same thing but while I was using it. Anyone else notice this? Did a reset and tested the light sensor and it seems fine but the screen still flickers.

Hello all,
I'm sure most of you will have seen the flickering icons in the notification area of the HD2. I've noticed that these can slow down any rendering done on the phone while they are flickering. Has anyone managed to remedy this?
EDIT: A video of the problem can be seen at: http://www.youtube.com/watch?v=Vo1Lm30EYaU

you have flickering icons? :S I have not experienced this, any further details/video of it?
Video uploaded, link in the first post.
I see the flickering you are referring too, doesnt it only happen when the wireless is connecting to a network?
that could hint as too why the graphics slows when it flickers
the phone will be doing some background work in attempting to connect to the network so the processing power will be impacted by this.
I do not think the actual flickering is the cause of the lower rendering speed however.
Unfortunately, this happens when ANY of the icons in the notification area animate. The WiFi is just a good example of it happening. I have tried performing other tasks on the phone while the icons are flickering and I have not found the performance of the phone to have degraded. For example, while the WiFi was connecting, I loaded the start menu and started scrolling though it continuously - it remained perfectly smooth and fast.
but you said it affected rendering? surely then you would notice it when scrolling the start menu because it would be choppy? If this is just a flickering icon issue then you could try using a taskbar mod that changes the icons/icon animations.
I have noticed that the wifi icon does flicker (though I have not seen it as bad as your video) I havent experienced the same flicker with the battery,volume or signal strength icons.
I have the same problem, sometimes it's making me nervous
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.
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 ...
Screen noise/flicker upon turning screen on
Upon turning on the screen, there is a slight flicker/staticy looking noise. Toward the bottom of my lock screen. It's easily replicated, but it doesn't do it every time.
I just want to know if it seems like a defect or it could easily be fixed by an update. Motorola might not even know about it yet.
Yeah mine does it sometimes, but not all the time
Sent from my XT1575 using XDA Free mobile app
I'm getting that too.
I filmed mine in slow motion when this happens on it and it appears to be an android software bug. It flashes the home screen then pulls up the latest app or vice versa. its so fast it looks like its just noise though.
you guys sure you didnt turn on the option for it to make a noise on unlock?
Are you guys or anyone else having this problem while being rooted? Because, I only started noticing this problem after I rooted
It happened to me before being rooted, if I had Moto Display on it never showed, it was only until switching to Ambient Display, or to neither Moto or Ambient Display that it started showing up.
Always running Notification
May be because of any always running notification. I too had same problem. Then I uninstalled the app that always used to have a notification running. Now the problem seems to be less frequent or not anymore.
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.
