Screen burn-in? - Google Pixel 4a Questions & Answers

Just curious. How many of you are seeing screen-burn in on your phones?
I use CF.Lumen to adjust the screen to be warmer at night. I notice some darker areas/burn-in with CF.Lumen enabled and the screen brightness dimmed to super low levels (using CF.Lumen's built-in darkness slider for Sleep mode)
What I notice is a sort of dark spot at very low brightness, and a sort of dark shadowy line running down the screen close to the left side. It's kinda annoying but I really only see it when I have text on the screen (and I'm trying to read text) at lower-than-stock dimness levels. I'm slowly getting used to it. At first I panicked thinking that my screen had burned in already at a few months of use, but when I have CF.Lumen off and I have the stock brightness slider set all the way to 0, I don't notice any lines or weird dark spots.
Then again, 0 brightness using the stock brightness slider is still VERY bright if you're coming from iOS's Accessibility settings. Android has poor screen filter settings and few good screen filter apps outside CF.Lumen and f.lux and I doubt Android 12 will change that.
So, are any of you experiencing screen burn-in? OLED burn-in is something that always has me worried. I try to avoid OLED phones for this reason, because I'm paranoid.

OLEDs have a finite lifespan. The brighter they burn, the shorter they last.
The higher energy blue emitters have the shortest life span, while red the longest.
Darker screen wallpaper, dark mode and less white icons/headers helps reduce wear.
Use manual brightness control and avoid going over 50% whenever possible. Don't use in direct sunlight... this is a killer.
Move icons and widgets periodically on the homescreen. Avoid prolonged white screen viewing and apps that are dark mode illiterate.
These practices also increase battery life substantially.
Use Screen Test to see if any damage is present.
After over 1.5 years of heavy usage and one battery replacement, my AMOLED display on my Note 10+ shows no signs of damage. How you use it day to day/what you view with it makes a big difference in display longevity.

[Q] Brightness Changes with Displayed Color -- Is it normal?

Hi, I am new to XDA, and this is my first post.
About a month ago, I grabbed my One XL in Hong Kong. Loved the phone very much but in the past several days, I noticed that the screen brightness seems to change with the background color. When the background changes from "mostly black/dark color" to "mostly white/light color", like when switching from appdrawer with black background to light-colored homescreen (ex., the "serene" desktop), the screen backlight will gradually (within about 1 sec. ) turn brighter. This is quite obvious if I lower the brightness level (I set it to about 10%), and at 50% the issue is barely noticeable. This looks like a battery saving method, but I'm not sure. I would like to ask if this is normal, or is there by any chance a way to turn this off? Because it is indeed very annoying to me. Currently using ViperXL 1.2.0 rom and Beast kernel. Thanks for your help!
P.S. The auto brightness is always turned off.

Rooted Marshmallow change system default Dim level.

Hi,
I am using my Nexus 6p in a quite screen heavy way (mostly in the car) and I am looking forward to reduce battery usage.
What I am doing at the moment is:
1) Use AutoMate in the car for navigation and music
2) Set up the screen timoeut after 15sec.
3) Use Caffeine app to prevent screen from going sleep
As an effect of this after 15 seconds my screen dims to certain level and Caffeine keeps this state all the time.
The thing is that the dimmed screen level is too high for me and I am looking forward to reduce it.
I realised that if I change the screen brightness to minimum then "dimmed" level is also lower so I suppose the system is doing something "When dimmed lower the current brightness level by x%".
I do not want to change the "screen awake" brightness level but just make the system to dim my screen by greater percentage so then I could get to nice and bright screen with just one touch without having to activate variety of apps.

screen brightness changing itself in constant light conditions, bug or feature?

Is it possible your obscuring the light with your hand or fingers causing the phone to constantly adjust to what it thinks is changing light conditions?

its possible, if the sensor is on the bottom bezel. never had this issue w/ my n4,5,5x, or p1 though.
My problem is more that the brightness doesn't adjust itself enough. If I'm on auto-brightness and in a pitch black room, my phone blinds me because it doesn't adjust.
What is everyone else using for display settings? I've enabled 'Adaptive brightness' but it's doesn't adjust very well. I prefer not to have to go to something 3rd party like Lux.
Mine micro adjusts in a dark room it's not terrible but it's enough to be annoying while reading because it grabs your attention. More noticeable on white backgrounds.

Any way to brighten the 'inactive' or 'A.O.D.' screen?

Here's my only problem with this watch : The active display is beautiful, bright, colorful, great to look at. Wish I could look down at my watch and see it everytime but I can't - it flips to AOD display no matter what.
I can live with that, but I'd like to make the 'inactive' display or the 'AOD' display brighter than it is. I have not found any way to do this.
Is there an app or a rooted modification to make this brighter? I don't need the active display on all the time, just want the 'inactive' display to be brighter so I don't have to squint at my watch during the day.
Does anyone have a solution?
Disable the "Low light" auto and AOD stay visible correctly.
I have "Auto low brightness" set to "off" but the AOD brightness still goes down to a level 1 brightness and is very difficult to see. I'd like to see it at a 4-5. Are there no rooted mods or anything that can fix this?
Yes, we must have at least brightness to 4 to see properly AOD. But if "Auto low brightness" is ON even at 6 is it dark with dark light.
I tried setting it to 10 while keeping "auto low brightness" OFF - but the AOD brightness is still too dim. I wish there was a way to change this.
I don't know of any way to do this for native watchfaces. However, Watchmaker allows you to customise the AOD to your specification. I have a Fortis watchface I downloaded and customised that the AOD just hides some complications and is fully visible. Yes, it does drain battery quicker but still lasts the day...
I gave Watchface a try and although you can customize much more, after setting the dimmer brightness to 40% (which was the max) it still looked just as dim, if not more, than the default Galaxy AOD display. I guess I'm the only one with this complaint - I work in a bright environment.
same here.. aod is way too dim. There should be an option to change the brightness of that even if it does use a little more battery.. There seems to be 2 different brightness settings with the aod that automatically adjust between the two but turning off Auto low brightness doesn't seem to make any difference. The point of having aod is so we can use it like a normal watch.. but as it is now it's almost pointless.. hope samsung fixes this in a future update.. but unlikely.. I use watchmaker but can't find the option to adjust the aod.. any ideas???
On my Galaxy Watch 42mm I use AOD Clock, it's an app not a watchface, but stays always on very bright and it seems to be moving slightly (amoled friendly?). But uses a lot of battery.

How Does Amoled Screen Burn In Work?

I asked the same question on r/oneplus.
So I've bought a OP 7 Pro just 1 month ago and I'm really paranoid about burn in.
I searched a lot about amoled technology and from what i read i assumed screen burn in it's not something recoverable. And I took all the security measures to not make it happen. Auto-brightness, screen timeout to 30s, AOD turned off, and i never leave a static image on my phone.
Today I noticed that when i plugged my phone and the colors screensaver started, the fingerprint icon left a visible mark like it was burned in. But it lasted only a couple seconds and then it disappeared. Same thing happens with the signal icon on the status bar.
So, is that screen burn in? Or it's just image retention? And why is it recovering? Should I worry about it becoming permanent? I'm not even enjoying the phone anymore :c
Sorry for my english and thank you
Not that big of a deal. Especially with screen technology these days. Walk into your local carrier store, or Best Buy, look at an old phone that has an amoled screen and that's left on all the time for display. That's burn in. When the image stays there after a long period of time and doesn't disappear when the screen is turned off and on. When I had my S8 and S9, it was noticeable that the clock and always-on home button shifted all of the time. With screen technology the way it is now, a lot of OEM skins have some sort of burn-in protection in place. I've left the screen on my 7 Pro on for hours on end, alas at the lowest brightness, with the screen timeout set to never and I've never had an issue.
I'm paranoid about burn-in too. I use navigation gestures and systemui tuner app to hide status bar. I use battery widget reborn to see battery percentage and other notifications can be seen in notifications pull down shade. Use auto brightness to change brightness more frequently. I use amoled antiburn app to check for any burn-in. All clear so far.
Since launch, Not much chatter concerning this as an issue... Enjoy your device
I have Google maps burned in..? I hate it because you can see see on a white background alot.
