It's been a while since I had a phone with an oled screen, and I remember that after a few months of use the screen would burn in in specific areas where the same image was displayed continuously, e.g. the notification and navigation bars.
Now I'm worried that enabling "always on", which makes the clock and notifications show up in the screen all the time, will cause this problem.
Should I disable it? Are oled screens better now? Don't they do that anymore?
I would imagine that Google has installed some type of burn in protection where it moves the images slightly to avoid this.

That's what I thought at first, but they don't seem to move at all...
What I've read is that the info on the screen moves one pixel every minute to avoid burn-in.
Yeah, same as the flagships, it moves.
My Samsung S9 moves the time/date on the always-on screen by a wide, very noticeable amount (up, down, left right). Which is (I think) the right way to avoid burn-in.
As best I can tell the 3a does move the always-on time/date display. But it's not by much. This is really quite surprising because, yes, I think AOD will leave a blurry region right in the middle of the display which inevitably is going to be noticeable. To test this I placed a Post-It note on the screen, on the base-line, just under the day, month, temperature from the always-on display, then let the phone rest most of the day. It appears to me that the image is shifting, down, by a few pixels. After a few minutes the image shifts up, appearing to return to it's starting point. Without a reference-point (the Post_It Note) I'm not sure I'd be able to tell the image shifted at all.
If the display moves one pixel per minute, and the display has perhaps 400 pixels per inch, then it takes something like six and a half hours to move to the entire AOD to a new spot on the screen. Seems to me like that's laughably slow.

This aod has been implemented since the pixel 2, I believe. That device is coming up on being 2 years old. If this was an issue, I believe we would have heard someone complain about it by now. Maybe someone has, but I haven't heard it. I would say just enjoy your phone and don't worry so much. But I'm no engineer and have no expertise in the field.

I have a 2016 Pixel, and the "always on" isn't always on. Maybe that's a setting somewhere, but functions similar to the old Moto X phones. The screen comes on when you interact with it for a few seconds, and then shuts off. Does the screen always display the clock/notification icons? That's definitely something I'd only want to be on for a few seconds at a time.
You can set it up both ways.
You can have it turn on when you double tap or pick up the phone, or you can have it to be always on, in which case it only turns off when you block the ambient sensors (so when it goes into a pocket, you put it face down on a table, and so on), otherwise it stays on.
Personally I set it up to turn on when I pick it up or double tap, really don't have the need to have it always on anyway.

A couple of times I was shocked to notice that the keyboard leds on my TP weren't shut down with the keyboard slid in. Since there is a slight gap between the keyboard and the screen, in a dark environment, looking at the TP's right edge, white light was clearly visible just 1-1.5 cm's above the stylus (display and the hardware buttons were OFF, so no, no light "bleeding" effect).
After promptly sliding the keyboard out and back in, the lights went out; actually they went out right when I started to move the keyboard, possibly indicating that there might be a loose contact somewhere. Once, I actually waited for the light to go out by itself; it certainly stayed on after the regular "timeout" value...
So, I wonder: if the contact that is supposed to cut the power to the keyboard when you slide it back in sometimes doesn't work, but the device thinks it's locked and doesn't "timeout" the leds anymore, can this be the cause of mysterious battery drains reported so many times on this forum? Sure enough it's quite hard to spot, especially if you're using a case for the phone. It would most certainly explain why battery drain varied on my device rather wildly even though the usage pattern hardly changed from day to day.
I tried reproducing the effect but it's quite hard (I'd say for my device it would kill the lights correctly at least 9 out of 10 times) and I didn't want to stress the sliding mechanism too much...
Anyone notice this?
Just so noone thinks I'm seeing ghosts, today, just after unplugging it from my laptop, eventhough the keyboard hadn't even been opened, I saw the leds were on again. Just to be sure this wasn't a "feature" I waited about 5 minutes and they were still ON. So yes, this is most definitely a bug and a quite serious one at that.
I took a photo with a friends phone camera (sorry for the low quality). The bright, white, dots seen in the pic are the leds from the underlying keyboard (the phone had always been shut, keyboard fully slid in: display and hardware keys were completely off and no, there was no light from the D-pad either).
I can now easily understand how, occasionaly, the battery managed to run out so quickly... Has noone noticed this before? Am I the only one with a potentially defective unit/keyboard contact?
I know it's probably been addressed before but I was hoping for some kind of explanation to the lightbleed? on my TF700T. I question it because I ONLY notice it at the initial boot screen - when the "2nd" bootscreen comes (when the display dims), no bleed - Also, no bleed when on a black screen, watching movies, etc - nothing. Is the initial boot screen just set at an amazingly high backlight that absolutely any tablet (at least any TF700s) would experience this? Perhaps there is an alternate bootscreen I could install and test? I am rooted...
thanks for the advice
PS - I HIGHLY doubt anyone would return theirs for this
Do you mean the two spots on the right side, or do you mean bleeding out from other places? I have light bleed sometimes on the right side but it goes away after a minute or so. Like it has to "warm up" or something.
no, not really - at the initial boot screen, I notice it on all sides but mostly lower left around the "home" icons-when it appears - after the initial boot, it's pretty much gone - I am thinking that the boot up for some reason is set to such a ridiculously high brightness that 0 bleed (if it is even that) is impossible. Can you post a pic of yours during initial boot or a video?
I get lightbleed occasionally but it fades out after a few minuetes.

I think its normal.. my original prime had the light bleeds near home buttons too. I happened to have one of those from best buys first batch the sent in plastic no bubble wrap mailers so it had a dent on the box on the same side the light bleed was the strongest. But so far of the two inifinitys ive opened up at Best Buy, light bleed was in the exact same places.
The teardown from the Prime showed that it is caused by the screws holding the screen in being too tight. If you take it apart you can fix the light bleed spots by adjusting these screws.

I have the same lightbleed on a bottom of my screen (at 3-4 spots) going to the right side as well (1-2 spot). They all gone on the 2nd boot screen. Do you think that this will decrease the life of the screen?
Also I have notice something else and I really not sure what is causing this. I have setup brightness to about 30%, then If I start watching anything (Netfilx, YouTube or movie) my screen is start adjusting (change brightness up and down) like Auto Brightness options is checked, especially when it has a white (or very bright) background color. It is very annoying and very distracting for you eyes. Never happen on my Prime.
Does anyone have experienced the same problem? Any idea how to fix this are very much appreciated.
Thanks

Regarding your second issue that is a known "feature" called Dynamic Contrast.
Quoting the All in one Infinity Guide stickied in the General Forum:
[ Q ] My screen constantly adjusts brightness even if auto-brightness is disabled
Yes,that is a "feature" called Dynamic Contrast but not all of us like it.Follow the directions from this post to disable but keep in mind that your device must be rooted.

Thanks for clarification. I thought that something is wrong with the tablet. It is look like that I have to take the root solution.

I have what sounds like the exact same lightbleed locations. If I watch something late at night with all the lights off it is very apparent.
I don't think it decreases the life of the screen, my TF Prime had much less lightbleed, but it never expanded or anything.
I'm using CN X2 Pro, 2 weeks old. I noticed that I get 1-2 seconds of ghosting/screen burn from the always on display when I unlock the phone. I still see the dark numbers on my light background. This fades after 1-2 seconds but I've never noticed this on other phones with AoD's? Do you think it's a sign my display might suffer in the future?
I have the same issue with AOD turn on, there is a ghost effect and disappear after few second. I found if you choose dimmer clock color, there is no issue. So, try switch to different clock style, try avoid those white color clock.
Hi. I have the same problem. What do you do guys? Other light spot and the same trouble
Hello. I think its's because of AMOLED screen.
I started getting it with AOD after updating to Android/ColorOS 11.
Previously, the AOD would move around the screen so it didn't happen.
I've had to turn off AOD because of this.
And what do you do? Send to service or something?

Interesting. Yes, prolonged static displays should be avoided.
AMOLED screens do not suffer from burn in. They degrade over time from usage.
They have a long but finite life span.
High screen intensity is the biggest degradation accelerant plus time. High heat ie sunlight should be avoided when possible.
The highest energy blue pixels burn out first, lowest energy red pixels last.
Damage shouldn't be observable in a screen so new. These screens are rated for thousands of hours.
The ghosting may be a firmware glitch and nothing more.
Avoid using over 50% intensity except when needed.
Don't use in direct sunlight except briefly.
Make use of black wallpapers and dark mode as much as possible. Whites and blues should cause the most damage. Reds the least.

So what do you suggest? Warranty, hard reset or just learn to live with it. can update help you think?

A hard reset will do nothing but waste your time and patience.
If you really have damaged pixels, warranty as the display is likely defective.
If it's not actual physical damage only a firmware update can fix it. It may take months or never come at all. So again, I send it back either to be fixed, replaced with a new unit or a 100% cash refund. Nothing less.
Use screen testing app like this one:
Display Tester – Apps on Google Play
Test your screen and figure out whether it has hassles.
play.google.com
I use Screen Test but can't pull up a link. Playstore may have pulled it... as usual.
I guess I will only send the problem is that I bought it abroad and it will probably take two months

That sucks. If the problem is physical it may degrade rapidly; a new display shouldn't have these symptoms.

if there is a bright point, you can see it for about 5 seconds on a gray background. the brighter the screen is, the clearer it is. after a while it disappears

Sounds like hardware. Either way unacceptable.
Hello, is anyone realize that if you put full brightness, go to clear sun and see the screen there is a turned square like "burn in" in fingerprint sensor area?
This is normal or my screen have an issue?
You have to see the screen in angle.
Using full brightness and especially in sunlight is a bad idea. Limit it to a few seconds at a time if at all. There many thousands of semiconductors in addition to the OLEDs themselves in a screen. Heat can damage them.
I always have my phone in auto mode. Today one friend "played" with it and show me that.
Lol, for some even the slightest details are noticed... It maybe normal; the result of how the fingerprint sensor is intergrated into the screen.
The Screentest app give you a better idea.
Blue pixels die first, red last. If it's present equally on especially these two colors it's probably normal.
hey guys got question for u all
i like so much the flip 4 but i sell it cause i had 1 major proble
i bought iphone 14 pro max but i really want my flip 4 again
my problem is any time im using the phone for facebook whatsapp and regular stuff with regular use (not even hard use at all)
the screen dimm to much cause the phone is warm
if i turn on the extra brightness its dimm alot faster with minimum use
so i i never used the extra brightness but always on the full brightness but i always use minimum use and the screen is dimm
any solution or its like that???? (the phone is ok i had 1 before and it was the same)
i have no case nothing i never pleyed games with my phone just regular use....any tips for what to do or this is how the phone act?
and just for you know im on android 13 latest thx for the help !!!
sounds like you have some sort battery saver turned on, have you checked in settings? this is not normal behaviour.

On the Flip 4 I use the Adaptive Brightness "on" setting, and Dark Mode. Your results may vary, but here's what I've seen.
In the summer, on a sunny day, I'll notice that the phone will automatically try to be as bright as possible, so the screen is readable. (I'm pretty sure when this happens the quick display panel's screen brightness slider color changes to orange. Maybe the color depends on the wallpaper/color palette.) And I never see the screen do this "extra bright" thing indoors. Only outside and only in direct sunshine.
So far so good. I think this is as everyone expects the phone to operate.
Given all this, sometimes I'll notice the screen brightness will vary, even though I'm still outside and still in the same brilliant sunshine. I've noticed this commonly when checking Google News, and for example, I'm reading a story and scrolling slowly through the article. In particular when the screen is mostly black text on a white background.
So, in this situation, that is, a largely bright background, in the bright sun, my phone will both:
Get warm to the touch, on the back-side of the phone, where the two batteries are, but not up where the cameras, CPU and memory are located. This makes sense because "scrolling text" isn't that demanding on the CPU, but I am driving the OLED screen hard.
Also the front of the phone (the OLED screen itself) can feel warm. Even in the screen's crease, away from the battery. Since the image is mostly white, all the OLED dots are "on" and give off heat. Then again, I'm in brilliant sunshine and almost any surface will get warm.
Further, I'll notice that the phone screen will automatically get dimmer after a bit of time (perhaps a minute or two of extra-bright before the dimming). This I attribute to the software doing one, or both of:
Dialing back the screen brightness, to prevent OLED burn-in.
Dialing down the power usage by the screen, to prolong battery life and/or limit the battery temperature.
What's more, after little more time, still in the same bright lighting conditions, perhaps reading the same story, the screen might be noticeably extra-bright again. It's as if the phone has given the display "a rest" and is willing to go "extra bright" again.
In short, I think the phone screen is trying hard to be brilliant in the brightest of sunshine. But there are limits in how hard you can drive an OLED screen, and how long the battery can power the screen.
All of this before we start to talk about what design limits come into effect when the CPU or graphics processing come into play, both or which compete for:
Power from the battery, and
The ability of the phone to keep itself cool.
This phone's form-factor is all about folding in half. A slab form-factor phone, I suspect, will be far more capable for heavy CPU, graphics, and provide a bigger battery and better heat disipation.
