Bleeding Issue

Can you see any kind of bleeding edges over a pitch black image in max brightness?
When I turned on the tablet for the first time, two white light bleeding points on the Samsung loading screen catched my attention, just over the bottom bezel.
As this panel is so bright, I am not completely sure if this is the kind of issues you have to put up with (like purple smearing on S4 or Note 3) or if I got a faulty screen.
I honestly think I have a faulty screen, but I would like to read your answers first.
Thanks in advance

yeah, i've got a very minimal amount of light leak. only visible on a black screen, in total darkness with full brightness. a combination that i'll never set it at in actual use. so, not an issue for me.

The bleeding is minor. Unless you are looking for things to criticise this is an excellent screen, one of the best on the market for any affordable (< $1500) handheld device.

Ok. Now I know that it is not a rare issue. By the way, I also discover mine has a black spot (several dead pixels). Not very annoying, but it is there. I'll try a refund anyway. Thank you all

Just got mine tonight and was all excited to set it up and play - then I found a small cluster of dead pixels. Very visible on a white background. Dammit. I also have the slight light bleed along the bottom edge, but nothing too bad. But the dead pixels are inexcusable for a $600 tablet, going back for an exchange.

I don't have any dead pixels on mine. It happens with every company, though I think you'll find Samsung has far less issues with it than others. I hope your next one is okay!

Thanks, I hope the next one is good too.
I find just the opposite with Samsung tablets - I usually have to go through 2 or 3 until I get one with a perfect screen. Or maybe I just have really bad luck.

Ugh, just exchanged at Fry's now and checked it out in parking lot. Good thing. Dead pixel on this one too. They were really nice about the 1st exchange, let's see how it goes with this one, lol

Update: From what I could see in the car, the 3rd one seems to be ok so far, no dead pixels... What was interesting though, the security seals on the first two boxes were made of paper, I opened with my fingernail. This 3rd one, the seals were plastic based, I needed a knife to open it. Maybe different factory or production run?

Does the Iris scanner make anyone else's eyes feel slightly "tingly"?

What's happening guys.
I just setup the Iris scanner on my note. It's extremly fast and accurate, almost as fast as the fingerprint reader for me. However, has anyone noticed that their eyes are slightly "tingly" while using the scanner? I asked my bro (we got the BOGO offer from ATT) and he said yeah he feels the same way if he's too close. I'm holding the phone a good foot/foot and a half away and it works fine, but my eyes still tingle a bit. Almost as if they're strained. I'm not sure if this is some placebo or maybe it's my glasses (I have a large -8.0 correction on my vision).
Anyone else experiencing this?

It was until I took the metal fillings out of my teeth [emoji14]

Yeah, feels like eyes got shot with a laser

Better learn brail! lol

I set up my iris scanner with my contacts in my eyes, and always wear my contacts while using my phone, but I have not had any weird sensations while iris unlocking.

that's pretty much what happens.
it lights up your eyes with light outside the visible spectrum, but if it's too bright it can still burn a little.

Don't worry. After 100 years won't matter. Enjoy the device now. ???

There is a note in the warnings that cautions against holding it closer than 8-10inches to your face. I suspect it could cause damage like any other laser. I am passing on use of this(plus it doesn't work with glasses).

Huh. It's been working just fine with my glasses.

Not mine. I have polarized transitions lenses though so maybe that's why.

The things nobody tells you about this great phone.

Hi V30 fans.
I got my V30+ 2 weeks ago and love this phone.
However there were a few things nobody ever mentions in their review like the great vibration motor, the sharp edges at the bottom or the plastic feel of the screen.
That's why I made my own consumer review of the V30. You can watch it here:
https://youtu.be/1Eejb64Cwy8
Did you notice similar flaws with your V30 and how much did they bother you? Cheers

I put a case on my phone, so no sharp edges on mine or my wife's.

None of it bothers me. Other stuff bothers me, not that though.

it doesn't really bother me it's just someting i noticed when I first touched the device but maybe other V30 phones don't have sharp edges. I use a popsocket.
Just a different question: When I set DND to only priority some app notifications like tinder show up even though I did't activate it. Any thoughts?

What bothers me the most is front facing camera, it's hideous, sooooo crappy, my 3 year old htc m9 had a better camera. Other than that I'm super happy with everything this phone has to offer

The software experience. I'm coming from a 6p. I also don't love the battery and miss an LED notifier.
Otherwise, phone is great.

Yeah Stock android is always the fastest but honestly I don't understand what's bad about the software. I had the S8 and think Samsung UX is way worse.

Really no LED? This is going backwards in time, back to my N6 that had to be rooted to get the notification LED working. This actually might be a deal breaker, leaving me with my HTC 10 until something else with a decent DAC comes onto the market.

Do you use peek? I generally find it distracting, whereas the LED tells me what I was being notified about by color.
Well at least I have a good reason to hold off on upgrading for a few more months now. In any case I'm grateful you mentioned it!

That's peek - peeks your notifications. At least on other/older phones, the screen turns on when you get a notification and again when it senses motion. I understand the V30's display just stays on all the time.
I guess I just get distracted easily...

I guess the thing is that it was the one thing I was most worried about and, while I miss it, I don't miss it as much as I thought I would.

Alright, first thing I want to clear up is this:
Plastic OLED does NOT mean the display is actually plastic. You CANNOT tell by touching it. You can tell the difference by touching the S8 and the V30? Both are glass! LOL.. Also, AMOLED is what Samsung calls its OLED displays. There's no LG AMOLED panel. So its not "plastic AMOLED", its just p-OLED.
Now, for the most important part about this topic, all recent OLED panels that have any kind of flexibility/curve are ALL plastic substrate OLED panels. Including the AMOLED panels on the recent Samsung S and Note devices. LG calls it pOLED (stupid choice for a name tbh, it causes this exact sort of misunderstanding!). So, the "plastic" just refers to the plastic substrate layer instead of the glass substrate layer used on OLEDs prior to the flexible displays. It's under the glass and digitizer, its part of the actual display panel, so there's no way you can tell the difference by touching or looking at it.
I agree about the sharp edges on the USB port, SIM tray cutout and headphone jack, it's one of the first things I noticed. Not an issue really, but feels like someone forgot to grind the edges down.
The speaker is plenty loud for notifications or the occasional Youtube video for me. I NEVER play music on a phone speaker and if I'm going to watch something, I almost always use my earphones. So, personally, it's a non-issue as long as I don't miss notifications.
Good review overall mate, just make sure you do the necessary research (doesn't take more than a few mins) and avoid making assumptions. Cheers!

S20( /+/Ultra) OLED - bad uniformity, too bright dark grays, green tint

Hi,
over in the ultra section, there is a thread about bad OLED uniformity and a green tint, which is really badly visible in dark environments e.g. in the dark grays used in many applications:
https://forum.xda-developers.com/galaxy-s20-ultra/help/green-tint-dark-background-low-t4065621
The attached picture of my display was made by zooming into the (uniform) 5% gray picture in a dark room with 25% brightness using an S10+. It is rather horrible and badly visible in normal usage.
Is anybody here expierencing the same issue? Please feel free to head over there, also, if it is not an Ultra.
Thanks and best regards,
Corwin

I have this problem too. I'm on my second S20+ now and it has problems too. I'll return both. It sucks.

That is really unfortunate. Thinking about trying another S20+ - but I think we should probably wait for later batches. I am also hoping for software optimizations, as it is better at 60Hz - but usually, nothing can be done about it.

How do you test for this ?

For me, I did not need to test for it, as I noticed it right away the first time using it in a dark environment.
In this post is a 5% gray picture which can be used and instructions: https://forum.xda-developers.com/showpost.php?p=82017239&postcount=17

I also had a bad uneven grey on my 512GB Ultra. Swapped for the S20+ and it's basically perfect. Good luck on the OLED lottery.

Mine does not have this problem. Is related to where the phone is marked for distribution? I'm on a US/Verizon handset.

Mine is also a US version. On ATT. Its just an OLED panel thing. Samsung used to have this issue a lot back in the S6 through S8. From S9 and Note 7 and on screens were great. I think with the new 120HZ screens the uniformity issues came back.

I think so too. S8 was really bad. S9 and S10 were great. S20 is bad again.

Exactly. Gotta be the 120hz thing.
If anyone has a really bad grey screenor not uniform. Return and reorder. Samsung customer care won't understand the issue so might as well just order a new one and hope you get a better one like I did.

Too bad my second one is still bad. Now I return both and order a Snapdragon model.

Oof. Good luck. Mines Snapdragon. Oh and Snapdragon is the better variant now anyway.

should I be worried if my whole screen is green when showing this 5% picture in dark room? upper part of the screen seems to be slightly brighter green - it is my first samsung and I cannot find anywhere how ''good'' oled 5% should look like...

My opinion: Of you need the picture to see it and do not notice it or if it does not bug you, you are fine. If the display is uniform, whatever it is like, I think it is ok.

Absolutely!

I have the same issue, S20+ 5G Exynos

So how do you test this again? Using a dark grey picture with the brightness set to 5%?
ETA: NM, I read that wrong. I downloaded the image and tried it at 25% brightness. I'm not seeing the same thing? Is it meant to be dramatic to be able to notice if it's a bad panel? I'm seeing a normal display?

On number 5 I can say that it is finally bearable. It was manufactured on the second of march. I did not check with the rest. I only opened them, handled them delicately and checked them. All were terrible.

Question 4 pixels

Hi,
Can anyone else see 4 pixels light up when the fingerprint scanner fails to detect fingerprint while being in whatsapp call?
I have attached video of it with 4 pixels lighting up on left

Yeah I've seen it before. Pretty sure it's some kind of sensor under the display. If you are on a white screen, and look closely, you can actually see them.

I believe it is the underscreen proximity sensor checking if it is an accidental touch or not
