I guess you love being at apple forums as well? Let's not forget oneplus with super bad flagships for last 2 years.
[Samsung Galaxy S23 Ultra] Guyinlaca:
A far more productive way to deal with this is find out what country of manufacturing and build date are having the defect, and which ones are not. You can check the box for the country and the website below for build date.

The two I've seen WITH the defect were made in Vietnam, with build date of January 11, 2023.

[Samsung Galaxy S23 Ultra] varcor:
These are the consequences when the manufacturer decides it has to offer a new model every year. It doesn't have the time to iron out all the bugs. The device is likely the best phablet (it's not a smartphone) one can own but it offers few improvements (specs wise) over the S21 or S22 Ultra's. If you have an S22 Ultra Exynos or earlier S Series beyond the S21 Ultra Variant it's a welcome improvement, otherwise meh. For me personally it's too big, unwieldy. I prefer a true pocket phone and the cost of year over year upgrading is excessive since Samsung slashed it's trade in valuations. For many cost is not a big factor when they chose to own the latest, greatest device, it's part status symbol and part functionality of certain features. But most won't use an S-Pen very often or utilize Dex. The device offers tons of functionality but few use most of it's features. I purchased a Infinex Zero 5G 2023 for a friend recently, a top shelf device, no but it offers a fast Mediatex Chip, 6.7" Full HD+ Display, 256GB Internal, 5000 MaH battery, 120Hz Refresh, MicroSD, 3.5 Jack, Dual SIM, 50 MP Camera with Wide Angle, 4K HD, NFC, Mirror for Smart TV's among other features. Cost - $210 USD. Few will appreciate or utilize the other features that a device costing 6 times more offers.

I am from indonesia and have Graphite exclusive model. Manufactured in China, 16 February 2023. Delivered to me on 20 February. This is one of the first thing i notice, since i unboxed it under bright sunlight next to my office room windows.

This "defect" would really un-noticeable unless the phone is under very bright light. I doesn't affect the way the phone displaying image, nor the touch. Hopefully it doesn't affect the screen bonding in a long term usage.

this doesn't really bother me. But i agree. For a phone with this price, this should not happen. Well luckily they give two years Samsung Care+ for free in my country, and shall anything happen, i will definitely ask for replacement within those time window
[Samsung Galaxy S23 Ultra] EtherealRemnant:
Korea 1/13/2023. It has an almost imperceptible "defect" there.

U1 sold in US.
[Samsung Galaxy S23 Ultra] evangelionpunk:
Excellent suggestion!
[Samsung Galaxy S23 Ultra] peterg21:
I initially thought it was too. My phone was manufactured in South Korea on February 2, 2023 (and does not have the flaw). However, I started thinking about this a bit more. Being somewhat clueless on the manner of the assembly of these phones, I realised that the displays are made at a plant(s) at a different location perhaps. So this is not restricted to a particular assembly plant but originates at the panel manufacturing plant(s). Date of manufacture of the phone is not necessarily a differentiator but can be.
[Samsung Galaxy S23 Ultra] MrDusan:
My phone's build date is Jan 13th and it doesn't have this issue. Under very bright light I can just barely see that there is a very slight curvature on the screen but not even close to what was shared here.
[Samsung Galaxy S23 Ultra] lil_kujo:

[Samsung Galaxy S23 Ultra] Guyinlaca:
My biggest complaint right now is the screen. The off-axis shifting is way worse than the S22 Ultra. That is when you tilt the phone at an angle, one side of the screen shifts to a blue hue while the other looks warm. The S22 Ultra had it at extreme angles which wasn't a bother, but this has it even with slight tilts. This effect has not been seen this badly since the S21 line and older.

The other concern with the dent in the lower right corner is that curved screens are known to pinch ribbon cables that result in a green or pink vertical line running down the screen. Say what you want about being knit picky but for $1199, this is unacceptable. I hope the retailer is good with returns and doesn't belittle the concerns.

Samsung Galaxy S23 Ultra minor defect in corner of screen

Some Samsung Galaxy S23 Ultra owners noticing a minor defect in the corner of their device's display screen. Here's what you need to know.

piunikaweb.com

Apparently for most it may not be a physical defect but rather an issue of light refracting through the layers visible only at a particular angle and light intensity.......

Still should continue checking yours and posting up to see if we notice any patterns to it.
[Samsung Galaxy S23 Ultra] hoss_n2:
By checking IMEI it says that my device is manufactured in Korea , but on the box it is written Made in Vietnam 🤣 which to believe 😄
[Samsung Galaxy S23 Ultra] Eagle 3:
Not on mine. Korea, 20-01-2023
[Samsung Galaxy S23 Ultra] MrDusan:
This!

I completely agree on the screen color shifting when viewed from an angle. I almost returned my phone thinking it has a faulty screen, and then i went to local shops and saw that all screens look exactly like that.

I still have my old s21 ultra with me and it's screen doesn't color shift like this one. Whenever i picked up the old device I was like "wow, this looks so much better".

[Samsung Galaxy S23 Ultra] borijess:
I have had this issue since my note 20 ultra. Top left. S22 ultra top left. S23 ultra lower right but barley noticeable.
[Samsung Galaxy S23 Ultra] blackhawk:
It's a good observation. An in depth review of the N10+ vs the N20U displays finds a slightly greater side viewing angle color shifting occuring with the N20U. The N20U was the last detailed analysis that site did of the Samsung smartphone displays unfortunately. The variable refresh rate couple with the ever increasing brightness makes color calibration/accuracy much more difficult or downright impossible.

The side view color shifting may have more to do with changes in the lamination techniques being used. Trading off color accuracy for variable frequency rate* or brightness isn't a good trade off in my opinion. Gamma calibration will exponentially suffer as a result. Many times I will hold the N10+ so the display is viewed off angle... without a problem.

*a fixed 90 or 120hz display is a more reasonable and doable solution to the calibration issues to get the faster refresh rate. Doesn't sound as innovative as variable refresh rate but in practice it yields better results you can see. Some manufacturers are doing this.

[Samsung Galaxy S23 Ultra] catalin78:
I got my 3rd 512gb s23u,the other 2 i returned them because of the bubble button right corner, the 2nd one ,the crease wasn't too pronounced. Anyway,i ordered from Samsung uk the graphite colour this time. The other 2 were black and green.

This one has it too, even bigger,i didn't need any light to aee it. We called it bubble as it looks like but it is in fact an indentation.

The other 2 phones were from EE. I talked to a tech guy from EE and he said right away that it's delamination of the panel and it could spred over time or not.
[Samsung Galaxy S23 Ultra] ionutdicu:
me too, exactly
[Samsung Galaxy S23 Ultra] LHic13:
Hello

How do you find out when and where the phone was made?

I am also concerned by the "bubble"

S23 Ultra green 256GB bought in France.
[Samsung Galaxy S23 Ultra] blackhawk:
Correct decision. At least one review site has the balls to call like it is, a defect.

Knowing Samsung's history, defect handling track record and their lacksidaisical support I would've return it the next day for a cash refund at this point. Lamination defects tend to propagate over time, ask Boeing or Airbus. The phone corners are high stress areas to begin with. At this price point it's completely unacceptable even if it's just cosmetic.
[Samsung Galaxy S23 Ultra] catalin78:
I have a galaxy s8(5 years old), mint condition as it was in a case and screen protector on,still functional 100% apart of screen burn. The amoled panel is perfect, my previous s22u,s22u, note 8,9,10 and 20 were perfect,why i can tell this with certainty is because on all of them i installed a screen protector on. I use a flash light to be able to see dust particles,like this i saw the dent on the 1st s23u.

I don't care about cosmetic issue or not, it is a manufacturing defect ,is like you buy a brand new car with a dent on the bonnet,the car function perfectly right,but it is a brand new car you wanted to be perfect,same in this case
[Samsung Galaxy S23 Ultra] blackhawk:
A indentation in a laminate implies something is missing or misshaped.

Wonder how many batches where effected or is it randomly present in most production runs? It had to have been noticed by QC...
[Samsung Galaxy S23 Ultra] m3ath:
I returned the phone to the warranty and they told me that they will contact you within two days
[Samsung Galaxy S23 Ultra] blackhawk:
Photoelasticity can be used to gauge the stress points in the glass used in the display. Samsung claims there are multiple thin layers of very thin glass laminated onto the display that provide waterproofing.

Polarized light viewed through a polarized filter will light up stressed* areas like a Christmas tree... why hasn't anyone done this and shown the results?

This technique is likely used by Samsung QC during manufacturing.

All you need is a cam (or view eye) with rotating polarized filter, a polarized light source ie another polarized filter in front of the light source. This is a more accurate variant of the more primitive above technique.

*invariably all glass will show these stress lines. Generally more highly stressed areas are more likely to fracture. Stresses between laminations will show up as well.

Tempered glass exhibits an interesting crosshatch pattern revealing secrets to it's strength.
[Samsung Galaxy S23 Ultra] pjaysnowden:
I don't have this defect. My screen is perfect. I don't have OEM unlocking toggle...but hey....
[Samsung Galaxy S23 Ultra] Guyinlaca:
I just exchanged an S23 Ultra with build date 1/11/23 made in Vietnam for one with build date 1/19/23 made in Korea. There is no screen defect on this one. There is still some minor color shifting on white theme but it looks more like the S22 Ultra screen. There were 3 in stock and 2 were made in Vietnam, this was made in Korea. Was the restocking fee worth the peace of mind? Oh yeah.

Another bonus is that the screen is much more responsive on this new device.
[Samsung Galaxy S23 Ultra] LHic13:
Good morning

Who among you traded because of the "bubble"?

Did you get a flawless copy now?

THANKS
[Samsung Galaxy S23 Ultra] @home:
I have the bubble & it's not causing any problems. I am not sending mine back just for a little 'defect' like this.

Could be months before I get a replacement.
[Samsung Galaxy S23 Ultra] pjaysnowden:
Mine is made in Vietnam....and doesn't have the 'defect"
[Samsung Galaxy S23 Ultra] ssj100:
To put in context my perspective, this phone was essentially "given" to me, so perhaps I've got less bias than many here about this. It was "pre-ordered", Made in Vietnam, 1Tb version.

Been trying really hard to see the "issue" on mine - if it's there, it's very subtle and there's no way I would ever have picked it up if it wasn't specifically demonstrated how to reproduce it. I've seen multiple pictures/videos of this, and I agree some people's devices have it relatively obviously.

Mine is so subtle that I wonder if it's a trick of my mind that is "willing" it to be there sometimes. I think I've convinced myself that it's there but on a very subtle level only. The way I've convinced myself is looking at the other 3 corners of the phone and seeing the subtle differences in light reflection - it's perhaps slightly more "wavy" in the bottom right corner, or at least the "bolded edge-reflected light" is a bit thicker.

Overall my main point is that it's likely very subtle on a lot of devices, although it appears some batches have it more obviously than others. Another point is that it's really hard to actually reproduce it, as I think you basically need to look at the screen at quite specific angles in relation to a very bright "pinpoint" light.

Finally, I'm quite skeptical that this "issue" will lead to anything functionally detrimental. But open to be proven wrong!

Bubble here as well. European model. Made in Vietnam.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
If it's still impacting newly made phones, it's obviously not a defect, exactly as they said.

For the record, mine is exactly the same size as it was on release day. Just a very tiny almost imperceptible blip that I never would have even noticed were it not for people pointing it out online.
[Samsung Galaxy S23 Ultra] nguyenlucky:
Mine is produced in May 2023 in Vietnam for the Australia market, has that wrinkle. I don't think that's a big deal anyway.

I am sending my phone for warranty for a different reason though (vibration seems to rattle near the Spen and loose power button).
[Samsung Galaxy S23 Ultra] blackhawk:
It depends on the degree of blur as well as location. A small amount blurring near the outside edges is normal. The less blur near the center region the better. It can also vary between lens of the same model. However most lens including ones the cost thousand$ have varying degrees of blur across the lense. The degree of blur matters. Some small amount of blur is always present.

No one has published the measured degree of blur on S23U lense/cam that I know of. This just makes it harder for you the end user to make an informed decision.

What all the above means is Samsung is likely being less than honest to what's going on here. Typical Samsung bsing like a little kid rather than correctly explaining the blur difference between lens or stating their blur specs and tolerances. Samsung's QC doesn't seem very tight anymore. This is another indication of this.

I'm not impressed by Samsung's upper management; to be blunt, it sucks. You know what that means if true... nothing good.

[Samsung Galaxy S23 Ultra] hand-filer:
EMEICheck
[Samsung Galaxy S23 Ultra] nguyenlucky:
Oh, I think we're talking about different topics here. You are probably referring to the banana shape issue in S23(+) camera, which is obviously an issue. Someone came to a service center in Vietnam and get a reply from the technician, telling him that replacing the camera or updating software did not solve the issue.

What I am talking about is the small wrinkle of the display panel in the bottom right corner of S23U, which is unrelated to the banana shape blur issue of S23(+).
[Samsung Galaxy S23 Ultra] blackhawk:
My bad. I had forgotten about that one. Samsung was evasive about the defect as well.

The display should be perfect especially at this price point. Haven't seen this in person so it's hard to be sure exactly what it looks like.

Your call.

For the money in many ways the N10+ is a more capable phone and the build quality on the Snapdragon variant is excellent. That's my thought and is in line with what I want the phone's mission to be.

At this point I don't trust anything upper level Samsung management claims. They earned that distrust by multiple examples of disinformation and absurd rationalizations for their poor decisions. The full extent of the issues with the newest Samsung releases will take about a year to fully settle out and be realized.
[Samsung Galaxy S23 Ultra] 2015Ducatimulti:
mine doesn`t, but I have had 2 other S23 Ultras and they did, I just received my Lime 512gb Yesterday straight from Samsung, and it`s a newer build date than my other ones, since it was already had May update installed and the serial number shows it was manufactured last month.
[Samsung Galaxy S23 Ultra] DUTCH Van Atlanta:
My 512GB Graphite arrived yesterday. No flaw in the screen that I can see.

Lable on the box says "Made in Vietnam". EMEIChack says "Production Location: Korea SEC on 25-05-2023".

[Android Head-Units] kux94:
Hello guys! Been searching the forum thin, and wasnt able to find anything.

Got this new android headunit installed. I have tried connecting with bluetooth, in android OS its turned off. I have accessed developer, and adb is gone.

Its build on top of android, with its own UI. And inside the ui, you can turn on bluetooth but in a restricted mode. You are not allowed to connect other BT devices than audio.

If i search for bluetooth in android it says null > connected devices > bluetooth. And I can swap the button but nothing happens.

I read inhere to some apps to check info. Almost "ALL" keeps crashing. I have a report and links for this item. Could be fun, if someone had any ideas to open this up.

hello, I have a coika 12.3", 8/128 gb. Overall, the tablet works quite well and is of good quality but I confirm the problems you have detected. I also add that with Android Auto connected in wireless mode, after a phone call the music or audio you were listening to on the car-tablet is restored and the system goes silent.

I also add that I haven't found a support site where you can download updates or report bugs like this one.
[Android Head-Units] arsdever:
I'm getting frustrated that the device switches to its own call screen whenever I'm in a call. Even when I'm using Android Auto. Does anybody know how to disable this functionality?
[Android Head-Units] kux94:
I didnt use the call function. Just used bluetooth from car, and then the rest in this radio. I had a sound issue, so I have actually sent i back. And waiting for it to be fixed. Its in the mail now.
[Android Head-Units] cobanoti:
I got this unit today. Anyone knows the factory settings password? Tried all found internet ,none working
[Android Head-Units] f1ux:
Try 666666, I have the unit from nunoo, it looks like the same one though.
[Android Head-Units] cobanoti:
6x6 worked. Got the info from the seller. I noticed the music stops when switching to Audi system. Is there any solution? The navigation sounds goes through the right speaker, any solution to sound go through all speakers lowering the music sound volume?
[Android Head-Units] f1ux:
I don’t have any of those problems using aux but I opted to use a carlinkit cpc200-cpca which has a setting to make CarPlay use Bluetooth for audio. So I pair the phone to Audi Bluetooth for better call quality and music.

the song titles then also show in the car dash.

music doesn’t stop when I switch
[Android Head-Units] cobanoti:
Where is that option? Or you use extra carlink ? It would be cool. I have an Audi A6 C7
[Android Head-Units] f1ux:
I have an a6 c7 also. The feature is in the auto link app that comes with Carlinkit.

carlinkit also has hardware acceleration for CarPlay so it’s a lot smoother. You can set it to 60fps.

do you have issues with the MMI screen partly being cut off on the android interface?
[Android Head-Units] cobanoti:
Wait ,you are using extra carlink hardware for carplay? So you connect your phone with carlink kit, not directly with the android unit? I have the android phone.
[Android Head-Units] f1ux:
Wirelessly but yes. It’s faster, more reliable/configurable. Also supports android auto.

steering wheel long press works with Siri too
[Android Head-Units] cobanoti:
Hi, I contacted the coika seller and got the 3.03 update today. But the MCU wasn't updated. Have problem with Bluetooth. If I uncheck the call option it won't connect.
[Android Head-Units] cobanoti:
One update: Today I installed Headunit Emulator app. It is like a carlinkit. Wireless Android Auto. Lots of option, and it can be set up to use Audis Bluetooth to stream music(the sound quality is much better)
[Android Head-Units] dolange:
Hello to everyone, i installed the coika 9 inch RMC Android display on my A6 c7. The microphone built in or the external mic doesnt work. Someone have this issue or know how to solve It.
