[Samsung Galaxy S24 Ultra] Guyinlaca:
I'm one of those people who upgrades annually as tech is my hobby. However, the S24 Ultra really has me questioning whether it is worth the money. It's hard to say whether the S23 Ultra was just that great or if the S24 Ultra was just a lazy "improvement".

SCREEN

The anti-reflective screen is great outside, however in many bright rooms, the reflections are just a bronzy color rather than white which isn't great. The screen itself may be "more natural" but there isn't the vibrancy and contrast that the S23 Ultra had. The grainy texture is also more noticable than the S23 Ultra.

DESIGN

Many have been asking for a flat screen for years, however this comes at the expense of ergonomics. The S23 Ultra was already a big bulky phone, and now we have huge, almost squared edges. The gentle curves on the S23 Ultra made it so much easier to hold, rather than a literal brick. Sure the Titanium frame looks cool, but teardowns are proving that the S23 Ultra was more durable.

CAMERAS

The S23 Ultra camera was a significant improvement over the S22 Ultra camera but now the S24 Ultra is virtually the same and even has some issues in certain lighting.

BATTERY LIFE

The S23 Ultra battery life was a huge improvement over the S22 Ultra, but is nearly identical to the S24 Ultra with moderate usage.

OVERALL

Many reviews cite "Quality of life" improvements year over year and up until now I could positively point to those. However the S24 Ultra leaves me wondering what I'm paying for. Sure, it feels slightly faster but it may be a placebo of smoother animations. Other annoyances involve Samsung's removal of real leather cases (vegan leather is a huge downgrade in quality and feel), better vibration haptics on the S23 Ultra, and missed opportunities to really make this phone incredible. Is anyone else feeling meh about this one?
[Samsung Galaxy S24 Ultra] hand-filer:
Definitely a lesser upgrade from the S23U than the S23U from the S22U.

Having said that, the more I use it, the more I like it.

Give it a few days. You can always send it back for a refund and continue with the S23U.

As for leather cases, I have used Bellroy since the S22U. Much better than the Samsung cases.

Another oddity I've encountered and I'm not sure if it's a One UI 6.1 bug or a screen issue. When I manually change the DPI in Developer Options, to say 450 or 470, the text gets blurry. On the S23 Ultra, the DPI could be set to any value and everything remained crisp. When I set the screen zoom to the lowest toggle level (411 DPI) and set the font to small, everything is crisp and clear.

Also, not sure what changes, but when flipping through settings, the color saturation of the screen seems to adjust. Sometimes it looks saturated like the S23 Ultra, and others it looks somewhat dull. It's worth noting that the peak brightness on this phone is only seen on auto brightness in very bright environments. 50% brightness on the S24U is less bright and vibrant than 50% on the S23U. Given everything I've seen using different variables, it's obvious why there are so many observations about the screen.

The grainy screen is only visible on dark grays. The washed out colors are visible only at certain brightness levels and can potentially be improved by selecting a warmer tone on Vivid mode. Blurry fonts are only seen at non-standard DPI. Google apps turning maroon and pink is another bug when editing QuickPanel settings in Theme Park.

Edit: 480 DPI seems to be the sweet spot for text clarity on a custom DPI.

The reasons why i bought the S24U:

Better screen, visually improved, less reflections.

Higher Peak brightness

Natural colors and not the unnatural "vivid" style. Do not know why someone wants that with a toplevel phone.

Battery life

Faster processor ( although the differences are getting smaller with every iteration)

Flat screen, easy tablet use with the Spen

Better cameras the 50MP 5x telephoto (versus the 10MP of the S23) larger sensor

Lighter ( not much, but still)

AI is very nice but will come to the S23 also..
[Samsung Galaxy S24 Ultra] blackhawk:
I like the curved displays as they house the One Handed Operation Plus app. The round corners and larger bezel I detest. The N10+ still has the best form factor and bezel/display ratio. Thinner and lighter too. My biggest reason not to even consider the latest flagship is no expandable storage, again.

There's complaints about the S24U display as well. Too soon to know how that will pan out.

I don't think Samsung is trying very hard. They hit the wall after the N20U and even it had some issues, old hump back and which side is the Right side for the spen? Then they forgot the Note name and all their power users.

Samsung flagships are almost an iPhone now...
[Samsung Galaxy S24 Ultra] Gallardo994:
Honestly I loved the upgrade from the S23 Ultra of mine. The anti reflective screen on its own is the reason to upgrade, at least for me. The flat display is also what I was waiting for, but for a lesser degree. Also, the gray option is dam great and reminds me of my old S21 Ultra. In addition to all of that, considering I am a beginner watch collector, circle to search is a lifesaver to detect watch models by image.

Dunno, the phone just feels more satisfying to use overall, and that is a win in my book. I wouldn't say I wouldn't live without the upgrade, but it definitely feels nicer. 24-series software features are gonna come to 23-series anyway, but duh I hate waiting.

I understand some other people might consider these upgrades not worth the cost, but hey, many peps many opinions. I'd say, if you can spare a grand or two without any problems, S24 Ultra is worth it, otherwise I'd suggest staying with S23 Ultra as it's still great to this day and will get more stuff soon.
[Samsung Galaxy S24 Ultra] eyeatoma:
I've got the latest version of Home Up and Good lock. I've got the s24 ultra and the last few days the task manager that I've customized keeps resetting to Samsung's default. It's say around with the one I chose (grid) for a few hours, then when I use it again, it's going back to the default. Didn't do this for the first week but now it's doing it, any ideas? Anyone else having the same problem?
[Samsung Galaxy S24 Ultra] sidfirex:
To me my s24Ultra is easier to hold , more confident in swinging it around and much much faster and better extremely happy!
[Samsung Galaxy S24 Ultra] 0rigin:
The phones right now are a buggy mess. I've issues all over the place. Patiently waiting for an update, not much else we can do.
[Samsung Galaxy S24 Ultra] eyeatoma:
Yeah thanks, I got to to seemingly work after clearing cache/data of good lock and then reinstalling home up. Let's see.
[Samsung Galaxy S24 Ultra] sidfirex:
Good lock, grid tasks, for 7 days now.. no issues here.
[Samsung Galaxy S24 Ultra] jaseman:
I agree with everything but you left out the most important thing...FLAT SCREEN!
[Samsung Galaxy S24 Ultra] blackhawk:
Flat screens collect debris while curved seldom do. The bezel/display ratio sucks on this big phone. It's easier to case a curved display and less bulky. Make no mistake this phone needs a case.

Samsung saves money on flat displays, less manufacturing rejects. Will this cure their delamination issues?😎
[Samsung Galaxy S24 Ultra] jaseman:
ROTFLMAO! Okee Dokee if you say so..SMH
[Samsung Galaxy S24 Ultra] V0latyle:
You may disagree, but don't be rude. Don't ridicule someone because you disagree with them. He has a point - curved screens don't have the bezel edges that flat screens do, and are less prone to collect dust and debris.
[Samsung Galaxy S24 Ultra] seth_space:
read again i would say ;)

And yes the flat screen is way better then the cirved screen with lost space and slippy edges. Apart of that the curved one is prone to damage. But still its something you prefer or not.
[Samsung Galaxy S24 Ultra] blackhawk:
At way time I was of the same opinion and there is a learning curve that goes with the curves. It took me a while to fully adapt but it was worth it.

With a the right case the curved display holds up extremely well. This N10+ has hit the concrete over a dozen times from 2-4 feet in a Zizo Bolt case with zero damage... so far. Make no mistake all these large phones need a good case or they will be damaged. The case needs to have slightly raised edge quards around all sides of the display and the case cam len protectors.

The only downsides with the curved displays is a slight loss of real estate and occasionally it gets in the way of cut/paste operations (simply flip to portrait mode). With the right case you get an easy to hold (not slippery at all), tough phone that's fairly slim, and prevents accidental touches. The curves aren't wasted space if you use the side swipe features they can house.

One Handed Operation Plus is a killer app the uses all that "wasted" space. Works so much better than Google vertical swipe, supercedes it and can control dozens of functions including advanced navigation functions. Completely user configurable and customizable. You set up the control zones on the curve not the flat part of the display to avoid false triggers...
[Samsung Galaxy S24 Ultra] loick2728:
The S24 Ultra is really, really good. I've had it in hand since January 23 and I don't regret this change. But to be honest, I came from an S22 Ultra...

My opinion is that if you own the S23 Ultra, it's not worth changing unless you like the flat screen.

Especially since those who own the S23U will be entitled to the AI option which is available on the S24U

The 2 phones (S23u VS s24U) are really very similar

You are just justifying your purchase lol.

The reasons why i bought the S24U:
[Samsung Galaxy S24 Ultra] losonn:
I also upgraded from s23 ultra to s24 ultra. A few impressions are below

Pros:

1x lens - notably improved shutter lag

5x lens - this is a big upgrade from the previous 10x *even at 10x*

5x lens - more stable preview at 10x+ zooms makes it easier to frame a subject at longer distances.

display - flat nice quality of life improvement, but inferior overall screen quality undermines this

durability - gorilla glass armor appears to actually be a big upgrade vs s23 ultra's gorilla glass victus 2

Cons

display - new panel tech has sub-pixel color bleed issues = downgraded display contrast for primary colors

zoom - less smooth than my s23 ultra, several steps behind current gen iphone pro zoom

wifi 6e - 6e implementation still bugged, still refuses to reliably see / maintain connection to 6e networks

displayport - dp support still stuck on dp 1.2 which caps you at 30fps when using dex at 4k
[Samsung Galaxy S24 Ultra] citytrader:
I´m waiting for my S24U, the camera in my S23U is pure garbage with its oversharpening and excessive microcontrast, video is useless and I´m using my Gopro that in daylight is night and night compared with my S23U.

RAW in Camera Pro and ExpertRAW are even worse.

For what I saw, oversharpenning is much less in S24U...

My decision for the new S24U is because of the flat screen, I never liked the curved screen.
[Samsung Galaxy S24 Ultra] blackhawk:
You realize there's no sharpening in RAW's unless you apply it (or there shouldn't be)

Samsung's use of sensors larger than 20mp bothers me and even 4 years their AI image processing was a menace. Is it one, none, or both doing these?

They may be doing goofy AI tricks to compensate for the lack of precision larger individual pixel sensors.
[Samsung Galaxy S24 Ultra] p.dixon0:
Personally, coming to the 512GB S24U from an imported 128GB Note8, 512GB Note9 (which I still have), imported 512GB SnapDragon S22U and then a 512GB S23U I've experienced expandable storage, 3.5mm jacks, curved, less curved and flat screens, misplaced and then corrected fingerprint scanners and dual aperture cameras etc etc etc.

Having actually owned and used all these phones I feel that I can actually make a valid comparison and give a considered opinion. Obviously everyone uses their own devices in the way they use their own devices, and each to their own - if we all liked the same things the world would be a dull and boring place, much like an iOS homescreen 🤭

Anyway, the flat screen for me is a revelation. I can finally use a tempered glass screen protector and my S Pen can finally roam the screen without fear of falling off the side. I also agree that the curved screens of past phones visually look better, the way they blend into the frame is truly beautiful - but as soon as I put a case on a phone, the visual benefit of a curved screen disappears and it just ends up being a regularly changed film screen protected dust collector that my S Pen falls off the side of.

I held on to my Note9 for so long because I feared the lack of expandable storage, the lack of a 3.5mm headphone jack, lack of 'proper' facial recognition and for some reason the in-display fingerprint scanner - but in my experience of actually having moved on, I personally don't miss any of it.

I will also say that I regularly check for firmware updates as I'm hoping they fix the AOD situation (the AOD clock / widgets are not separately configurable to the lock screen clock / widgets) and no, the 5x camera is not as good as the old 10x on either the S22U or S23U at 10x zoom.
[Samsung Galaxy S24 Ultra] citytrader:
RAW since S23U is not RAW as you find in mirrorless camera where the data is sensor data, Samsung is cheating encapsulating JPGs in a DNG container creating a fake RAW (because of this apps like LR can not use AI denoising in this fake RAWs because there is not sensor data), otherwise you wont get the oversharpening Samsung is applying in its JPGs creating a false perception that the image is better or to cheat because the glass they use is not the best for a phone.
[Samsung Galaxy S24 Ultra] blackhawk:
Damn, you be right. Samsung has gone far beyond just being lame. Outright falsehoods and cheap gimmicks. Another dozen nails in their coffin lid.

I just did a comparison between my two N10+'s, one with over 9k hours on it, the other with a couple hundred hours. The colors, brightness, tones, etc using Screen Test and a pro color chart everything is so close I can't detect a difference. No color shift to red, perfect.

You think these new Samsung's will have that level of display longevity? Even the color calibration is bad from the factory now. In the last 4-5 years Samsung has changed a lot and much of it isn't for the better. Same for Gookill Android.
[Samsung Galaxy S24 Ultra] Guyinlaca:
We have to give it to Samsung, they fixed the gesture navigation and the screen vividness fairly quickly. Apple would have passed these off as intended changes.
[Samsung Galaxy S24 Ultra] citytrader:
I just received my S24U, the red colors are still rendered bad, really bad, worse in 50mpx 5x

Since S23U Samsung is not able to calibrate the colors of the camera, I can believe this.

Only JPG because Samsung RAW is packed JPGs, useless. (CLICK IN THE ATTACHMENT)

IMAGE COMPARATIVE
[Samsung Galaxy S24 Ultra] hand-filer:
Send it back, get a Pixel. Maybe that will be a closer match to your professional Cannon camera.
[Samsung Galaxy S24 Ultra] ajarosz:
In RAWs yes, but Samsung does not produce RAW files in their apps.

Here you have a conversation about it:

Gcam

Anyone tried Gcam on s24 ultra The x1 has Purple pictures Any solution All others lences are fine Any working version

xdaforums.com

Whether you choose "RAW" from the base camera app or ExpertRAW, they are compressed, preprocessed files. Yes, with some extended ability to play with them, but preprocessing applied there cannot be undone in e.g. Lightroom. Even with sharpening on the 0, ExpertRAW files have these ugly sharpening artifacts.

After posting I realized, that you have already posted proof of that.

It is shame, that to actually fully use camera, we are forced to install 3rd party apps.
[Samsung Galaxy S24 Ultra] blackhawk:
Ummm, see #26, I agree. An unbelievable fubar and the display calibration is way off too.

Samsung's doing the Gookill thing, keep messing with a good product until it's broke.
[Samsung Galaxy S24 Ultra] citytrader:
After one day of having de S24U, here are my impressions compared with my S23U:

- Wifi 6E 6ghz still not working in S24U and S23U with the last update, this is not acceptable for the cost of this devices.

- I like much more the screen in S24U (firmware AXB7) like the anti reflection, colors that I use in natural mode and is way better than S23U and flat screen, about the brightness I think the anti reflection is what make a difference under the sun, I didn´t find any issue about grainy screen or other problems people name in forums in my unit.

- 50mpx 5x camera, this is a plus, I don´t think what is the use of a cell camera that has zoom more than this, 5x now can be used for portraits for example.

- Finally less sharpen shots with 50mpx x1 camera compared to the oversharpened shot of my S23U (I think this is software), the 50mpx x5 needs to be fixed because it oversharpens like my S23U in x1 ruining the shots, probably a software fix and S23U could take same 50mpx x1 shots if the oversharpened was solved in software.

- Looks like the modem consumes more battery in S24U compared to S23U.

- Video pro mode supports UHD/120, but I need to do some testing in the 4K/60 video quality to check if it surpasses my Gopro Hero 12, something my S23U never did.

Camera Pro mode and Expert RAW (much worse) are totally useless, they ruin the picture, never use them.

In Summary, besides de screen and the 50mpx 5x camera, the rest is the same or can be done in software.
[Samsung Galaxy S24 Ultra] Misterxtc:
My son has the 23U and I'm glad I waited for the 24U just for the flat screen. I'm actually coming from a Pixel 8 pro witch now is my wife's. The only problem I have is the camera brightens up the pic a bit too much in lower light compared to what I came from and that is fixable. Other than that the 24U is better in every way for me. I haven't had a single problem listed here. Getting rid of that darn pill at the bottom of the screen without root is a huge bonus lol.

EDIT: Most of all I'm glad I don't have to nit pick on such a nice phone and enjoy it unlike some here.
[Samsung Galaxy S24 Ultra] kingwicked:
No 1 and Main Reason To Upgrade.

Flat Screen

1.I am tired of this useless cosmetic edge display after using them from S7 Edge onwards. A nice way for Samsung to earn more from repairs. it is just crap for me. It has nothing but an inconvenience in term of physcial handling.

2. For me N20 Ultra is Slippery when i try to hold it without a case. S24 Ultra without cover has way better grip. I believe more in functionality then this edge non sense crap trend.

3. I have upgraded from N20 Ultra 5G N986B Exynos 256gb + 1 TB sandisk microsd storage to S24 Ultra 512gb with official warranty. Buds 2 Pro have been offered free with it by Samsung in my country.

4. i waited 3 years to upgrade only to see if sdcard slot returns which doesnot seem imminent at all now. I am getting 2 x Screen on time with same usage as N20 Ultra that has a brand new battery and running latest available firmware.

5. I am pretty happy with S24 Ultra i am getting around 8 to 9 hours of screen on time as compared to 4 to 5 on N20 Ultra.

6. I have been pretty happy with N20 Camera even till to date. So I dont have any issues with S24 camera as well..

@losonn

Are the display issued with color bleed what makes the display to me seem really odd in low light? When you really turn the display down there is something I'm struggle to get used to, maybe due to contrast, it seems to irritate my eyes.
[Samsung Galaxy S24 Ultra] blackhawk:
"Color bleed" seems to be a software or firmware anomaly. Could be artifacts of the display's active matrix too.

Try setting no wallpaper or flat black. I've seen it on N10+'s at very low ambient light levels (display brightness manual). It happens on portrait mode. Never visible except in very low ambient light conditions throughout brightness range. Visible only on the darker near off pixels.

It more like pixel ghosting. Near off pixels on the same horizontal line get a very low level digital brightness assigned to them that is higher than the actual digital value. I think it has to do with the way the system does overlays. It's not present in Screen Test and for me it manifests itself on homepage. Maybe 100% caused by app(s) themselves.

I'm still playing with it out of curiosity, comparing both my N10+'s.

Human vision is not linear at all especially with colors and rapidly skews as the light level falls.

The color sensitive cones at the center aren't that light sensitive but the rods on the peripheral are. The visual cortex of the brain seamlessly integrates images captured by the cones and rods of retinas; it does a huge amount of processing even adjusts the focus of images to compensate for each eye's lens anomalies.

Increase the brightness level until it looks "right" and is easy to view.
[Samsung Galaxy S24 Ultra] willhub:
I have to have it quite bright, to be fair I can never fully get it right. If I'm honest I'd say I preferred my S22 Ultra's display, the extra brightness of the S24 Ultra isn't that note worthy. aside from that the phone is a huge upgrade.
[Samsung Galaxy S24 Ultra] blackhawk:
Color calibration seems to be an issue on the S24U's. I use about 20% brightness or so in a dark room depending on what I'm viewing.

I rarely use full brightness except briefly in sunlight as doing so greatly increases display wear. Even on this display it's bright enough.

Normally I never exceed 50% brightness and about 35% is normal.

The SOC is better and apparently more efficient on the 24. Samsung started goofing up the cams as the pixel count climbed beyond 20mp.

There's a lot of deal breakers for this newest release though. One of the worst is no expandable storage. Even 1tb isn't enough capacity for me. wtf, a 256gb S24 wouldn't even begin to cut it.

About 70gb is in the download folder waiting to be vetted for transfer to the data drive. Really I want to have 2tb micro SD card capacity not zero! Thanks drop the ball Samsung for nothing! Again.
[Samsung Galaxy S24 Ultra] willhub:
What do you need such storage for? I have never needed more than 128gb so 256gb is luxury. Any download tasks I remote my desktop
[Samsung Galaxy S24 Ultra] blackhawk:
All my computers are dual drive, even the Dell laptop. Only the OS, apps, download and dcim folders go on internal memory. All critical data goes on the unencrypted data drive. This provides a firewall if the system crashes and normally protects the data. It organizes the critical data for redundant backup as well.

I download movies instead of streaming as it greatly reduces battery consumption and allows me to have greater playback control including picture gamma etc.

My complete high res music library is in my pocket as well and instantly accessible.

All my apps including system apps are stored as installable copies, no Playstore needed. I csn do a complete reload after a factory reset with no internet needed and minimal lag time. No cloud backup required. Only Gmail is kept in the cloud for security reasons.

I also use internal memory as scratch space. I like having lots of fast scratch space. It's not empty memory sitting there.
[Samsung Galaxy S24 Ultra] nurps:
Or they are just doing it wrong:

Good luck getting such complex issues past costumer support to the people that matter.
[Samsung Galaxy S24 Ultra] Virgo_Guy:
Anti reflective property of the display is the only thing I've liked so far in the S24U over the S23U.
[Samsung Galaxy S24 Ultra] force70:
I upgraded from the 23 ultra pretty much for the flat screen lol.

Prefer the 10x zoom on s23 ultra though I think they shoukd have left that as is.

Getting about 30 min more SOT on the 24 ultra.

Definitely keeping my S23 ultra as well though shes a keeper. Ill go back and forth between 24 ultra and fold 5.
