Ghosting effect and rolling shutter - HTC U11+ Questions & Answers

Did you guys notice visible ghosting effect when scrolling something? Especially with gray background screen looks very blurred. In comparing it to my pixel 2xl and s8. Very annoying.
Also, when recording something with horizontal move there is very visible rolling shutter effect.

I must say I noticed it more when I made my display warmer. Recently made my display a bit colder to match the Mate 10 Pro and now I don't see the ghosting anymore

Near-black areas of the screen are way lighter than it should be

I have a Galaxy S6 with this issue where very dark grey areas of the display are displayed in a lighter colour. I first noticed this when I copied over my background from my old S5 (i.redd.it/9ot00213jzr01.png). Instead of a smooth transition from the edge of the planet to outer space (on the top side of the image), there was a VERY noticeable halo, and you could clearly see where the image transitioned into fully black pixels. This was noticeable on my old phone, but the transition was extremely smooth and so you had to look very closely at it. It's also noticeable in the Reddit app. I use AMOLED night mode, and some areas, especially when loading in a subreddit, there is a colour that looks almost exactly like black on my S5, that looks way lighter on my S6. Is this a known issue? If not, what's going on? Can I fix it?

Screen ghosting when scrolling?

Hi guys,
Had my lite for a few days (SM-N770F/DS) and liking it a lot, although still adjusting to a few Samsung software quirks.
I'm not too impressed with the screen though even though reviews all seem to say it's good. General image quality is fine but I get some pretty bad ghosting/motion blur with text when scrolling, most noticeable when scrolling fairly slowly. White also goes a bit blueish when viewed from anything other than dead on. Anyone else have this issue? The scrolling ghosting is the most annoying. I've come from an LG G7 which I can only assume was 60hz so wasn't expecting to notice a difference. Could I have a bad screen?

Why is the screen a little warm (yellow tint) on the Pixel 4a

Just moved to Pixel 4a from an LCD display and I notice that the screen is a bit warm. Do others notice the same thing?

Yep. There are some options in settings related to the display (settings/display/colours where you can choose natural, boosted or adaptive which make very little difference, and in accessibility there's a promising looking rainbow under colour correction but sadly there are just a few colour-blind related presets) but nothing which would let you set the white balance manually.

Yep - which I appreciate. Obviously personal preference; native tuning options appear limited based on a bit of early experimentation.
On a related note, integrated "night light" (blue light filter) does a poor job with dark themes; throws off weird casts on light text when scrolling. I find it too distracting to use; just lower the brightness a tad more or use a 3rd party tool.
Looks good to me, where I can tell is looking at skin tones I find them very natural.
Got a picture of a beach water deep blue, sky look natural blue.
Taste maybe but it like it the way it is.
The setting mentioned my screen is on Adaptive, changing it does no effect much ??
Yes the screen is slightly yellowish and can't be changed even with the available presets. Fortunately I don't mind it personally since I prefer warmer whites compared to cold tones.
Yes, quite annoyed in warmth difference in the beginning because I was still using both 4a and my old phone actively. Searched here n there to make it cooler and also tried to make my old phone screen bit warmer to match (cause I just hate the difference not the warmer screen), but I don't like it even further with the tuning
All I can say is give it time, you'll slowly adapt to the new warmer screen
Yes I was just using a Moto One Active for a few weeks, which has a surprisingly decent LCD screen with perfect whites, and now that I'm back to using a Pixel 4a again I'm noticing that yellowish tint. Also had the galaxy s20 FE somewhere in between , which was obviously superior to both lol.

Question Slight Greenish tint on top of BS4 on grey background when brightness is lowered

It's been 5 days since I ordered my black shark 4 global 8/128 overseas.
While experimenting some things through my phone, I noticed that on a grey background, on the upper part of my phone is a slightly greenish tint.
I am on a dark room and light are tuned off, and I lowered the brightnes to maybe like 15-20% and that is the time when the tint is noticeable. I'm on ultimate refresh rate(144hz) and the tint was slightly reduced when I turned down the refresh rate to 90z and 60hz.
I researched and found out that this is a common phenomena on amoled screens. Some brands specially like one plus fixed it through OTA updates.
I also thought it is because our model is brandnew and still not stabilized, also the new E4 amoled we are using.
Can someone enlighten me if I'm correct? Is it fixable via OTA update? is it a software issue?
(I can't take a photo of the issue , I don't have any other equipment which can take the actual phenomena I am saying)
I've tested going down to 15-20% and I can't see that. Maybe is common in certain devices. How can you set the 144Hz? I only can set "natural" setting in the refresh rate which is 120 Hz according to the developer options.

Question Galaxy S22 Ultra green tint when looking from the top (bad viewing angles) Problem

My Galaxy S22 Ultra has a really bad color shift when looking from the top. The screen gets a green tint even when you are looking only a few degrees from the top. You can see it here:

(It's more apparent in real life than in this picture)
Looking from all other angles than the top the display looks fine. But it looks like the screen is shimmering if you turn the phone a little. I tried to caputre the effect on this video:
https://imgur.com/e7PghPU
I have my display set to WQHD+, adaptive refresh rate and vivid mode. The brightness when I took the photo was around 60%, but the problem occurs at all brightness levels.
My previous phone, the Galaxy S20 5G, doesn't suffer from this problem. The screen does not change color at all when I look at it from a slightly different angle.
https://imgur.com/H2S3KwV
So I'm wondering if other S22 Ultra users have had the same problem or if my phone is just broken and I should replace it?
Thx for your help
I have to admit I don't "see" it. I think the brigthness and the rounded edges may cause a somewhat "dark" line depending on viewing angle but I don't think it's a defect.

I also do not think that it is a manufacturing defect because I checked all the devices around me and they were the same degree of green, do you think it is because of the new type of glass Victus 7 Plus
I had the Note20U and it was common to see that on the edge on white backgrounds, which is why you can't see it in "flat" phones like the s21U and S22 non ultra series. I think the same applies to foldable phones when viewed in a certain angle with white background.
Mine does the same if I look at the screen from a very off angle. Had not taken note of it though until you pointed it out. Guess I was just not expecting a good quality view from such a steep angle. Just out of curiosity, I looked at a similar angle at my computer screen, TV, Kindle, Tablet, and an old phone. They all have various degrees of imperfect display when viewed from a steep angle although the shift in color was most noticeable on the S22. But still, I guess I would not consider it a defect.

I am a user of all versions of Sam and all devices have different Vision angles, but the Galaxy 22 Ultra is annoying and I expect because of the 1750 nit brightness
Mine has the same issue. I bring it to the Samsung center. Their demo device was the same. So i assumed it wasnt the manufacture defect. And most of the time, no one will look at the phone from the top down like that. So that was not a big issue at all. We should be thankful that the grey uniformity is much better than those from Sony or LG. The grey uniformity in low light on those phone were abysmal
It's not a manufecture defect, this is "normal" to curved screen on some viewing angles, same happens with the flip and the fold and the N20U, the flat S21/S21+/S21U/S22/S22+ do not have this issue as there is no curve

I did not have this problem on the Galaxy S21 Ultra, and it was not that bad as is the case on the Galaxy S22 Ultra, the color of the screen changes to green, which is very clear for the simplest tilt of the screen

This is a problem, which is defined by the bad viewing angle, and it may be worse than the uniformity of the gray color, which may appear only in gray and in weak lighting conditions, but this problem is annoying because it accompanies you with all light colors, and it is a problem that appeared in the first batches of the Galaxy S21 Ultra and was referred to by some reviewers and it was widespread in the days of the Galaxy
It's faulty. My 1st S21 Ultra behaved the same way. Meaning it had a very aggressive color shift with the slightest of viewing angles. I understand OP fully.
I have the same green shift as well on my S22 Ultra. It was not there on my S20 Ultra. It is more likely due to "improvements" in the screen, what you gain, you lose elsewhere. While the green tint is there, it doesn't affect me as I look at my phone directly. Others trying to peep over my shoulder can enjoy the green shift.

Return it and get a phone from a different manufacturer or stop worrying about it.
Those are your only two options.
