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.

Hi guys.I bought a new phone today - Asus p320.Everything is ok or maybe not...When the screen is off,there is some king of a spot in the middle of the screen which differs from the rest of the screen.The strange thing is that it's only viewable when using luminescence light... It cant be viewed on sunlight or on normal lightbulb.And when the phone is on,there is no sign that there is a problem but it's really freaking me out. So if you can tell me if thats a problem or not,i'd appreciate it very much.Thanks
if its only viewable in luminescent light (i'm assuming you mean black light), then it's probably just normal.
however, please do define luminescent light
well hmm i'm not sure i can define it really.i mean the lightbulbs that emit luminescent light if i can say it that way
do you have a link to a picture of this kind of bulb?
have you checked to see if this issue is common for your device?
how badly does it bother you, because if its only visible in a certain kind of light while the screen is off, it can't be that important.

something like that.
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.
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.
so to tell in brief what i did today i took it in the rain running
i cleaned it with sanitiser
here is a picture can anyone tell me if this can break my display in long term is it repairable ffor cheap
and kill my phone its in the right hand corner
What phone and type of display?
Looks like you got water inside.
Power it down immediately.
Pull rear cover and pull the battery, ASAP!!!
Place in a warm, dry room with a fan on it for a few days.
Connect battery, boot and inspect display.
Reassemble if ok, use new OEM seal for rear cover.
No time to dilly-dally Mr. Wick... tic-tok
The screen brightness and color are adjusted automatically to react to ambient light conditions. Usually the change is so gradual it's barely noticeable, but can be fast if the light hitting the screen changes rapidly and substantially. You can choose to disable this behavior, but you should give it a chance first
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.

sure man i never use battery saver always full brightness all the way up then the phone get hit very easy and dim the screen the temperature outside is around 25 c
nobody got this iisue? no way!!
It is clear that your mobile phone has a technical problem that needs maintenance, but try to return it to factory settings

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.
