Light Bleed

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.

Broken screen working again on low battery

Hi guys,
Some while ago my oneplus 7pro felt from the stairs. The backside is complety broken, but the frontscreen was ok because of the screenprotector.
After a while i noticed 'a lot' of dead pixels on the lower left side of the screen. The phone was still usable so i didn't bother about it.
Suddenly during normal use, my screen started flickering and my screen went off. It seemed that the screen was devided in 2 where the notificationbar was on the same height of the broken screen pixels.
I could see some things, but with a green film. But not possible of unlocking the screen.
I tought that the screen was completly broken and i moved to a spare phone.
I still hoped that the screen would do some sort of a reset when I let the battery completely drain, charge a bit and try again.
I checked almost every day on what percentage. But when it was on 13% (or nearby that %) the screen was working again like nothing happened before. I tought it was working again and charged it.
Because it worked again on a low percentage, I tought it may be a lower refreshrate of some sort of stuff that is on during battery save mode.
I left it charging some small time, tried again and screen was broken again.
I tought it was a lucky shot, so i didn't bothered again about the phone.
Yesterday i checked my phone again out of curiosity, and guess what, it was working again.
So I'd like to know what might cause it to work again on low battery. I lowered the resolution and refresh rate already.
Anyone who got an idea?

Nothing short of taking the phone to a repair shop will restore your phone to normal.
It's just going to get worse, there's nothing you can do to stop the progression, short of a repair & even then, you're probably throwing good money after bad, considering the type of damage incurred.

Can't be sure, my guess is some voltage leakage on higher voltage and short the screen somehow. If you can try de assemble and re assemble the phone. Just my guesses.

I suppose the higher the voltage the phone is able to provide the screen the worse it's going to get. Send it to OnePlus. Don't get it done independently, they cost way more

Fingerprint "burn in"

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.

Stuck pixels at 60hz and not at 120hz

Hi I baught a Galaxy A52s 5G two days ago and I noticed after switching to 60fps from 120fps that 2 pink stuck pixel appear in top left area of my screen. When I turn the refresh rate to 120 the pink pixel color disappears (they works normally). Any game running at 60hz also shows these pixels. Last time I was playing a new stuck pixel appeared, this time its color is cyan, when I looked at the pink pixel that gets stuck i found out that it started working normally, and after 1 minute the cyan one disappeared and the pink reappeared again. After inspecting using a white image i noticed another light blue one at the top too. When I play Genshin Impact it annoys me sinse I have never had this issue with my previous galaxy phones. I'm asking now if there is a fix to this. Thank you to anyone who will reply to me.

Try clearing the system cache.
Try a hard reboot.
Try it in safe mode.
Test the display with ScreenTest.
Factory reset, test before loading 3rd party apps.
However it sound like a defective display matrix or mobo. Return it if you can't resolve the issue.

The first three did nothing. the display test in 60hz shows the defect pixels while the same test in 120hz does not show any.
Does this mean that its definitely a hardware failure ? i hope that its only a software issue. I used the samsung members to report the error, I dont know if they wilp ever reply, I reported yesterday night.
The defect pixels are visible as soon qs I click on the 60hz and hit ok in Display settings, and they magically disappear after selecting 120hz and hiting ok.
Edit: knowing the samsung service in my country i'm almost certain that they will just mock me and laugh about this as its not really visible unless you really look for it.

I'm leaning more towards it being hardware than firmware in this case.
Samsung has had a lot of issues with their variable refresh rate displays.
I would really make the seller eat this one.
Your call.

Thank you for your replies. I wish i could make them change the phone but i'm certain they wont. I read in many posts of people who encountred the same issue, and even if they accept to replace the screen I know that the people who do repairs at samsung are really bad and dont care about scratching your phone or using visible glue to assemble it, I had an experience with A20 which had its fast charging broken and only charged at 5w, they replaced the bottom piece that houses the usb port but the back was very scratched and you can see the glue used, and I wasn't even sure if its really mine or someone else's phone as they factory reset it before working on hardware stuff. Let alone the time they need to get the part and fix it.
I'll just hope that they'll fix it, a friend of mine told that screen hardware defects can be corrected by software, bit if it was hpu defect i dont think there is mush they can do.
Anyway thank you for your replies its really appreciated.

I would do a refund for cash. Not sure what consumer rights you have in your country.
In the US I can right the defective product and if a MC or Visa was used the bank can do a charge back to the merchant for a full refund.
I think it's a matrix failure, a capacitor(s) or thin-film transistor(s). It could be the OLED pixels themselves. They are very complex displays.

Question about screen dimming

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)

It is clear that your mobile phone has a technical problem that needs maintenance, but try to return it to factory settings

maybe i use app that make the phone to hot the the screen dimm?
im using whatsapp facebook instagram and messanger maybe? anyone knows?

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.
