Just got my phone. The txt on the apps and main screens and just about all txt looks very blurry. Pics and such are perfect.
Is this something others are seeing? didn't see anybody mention it elsewhere.
Thanks!
Or is it that it's just not as clear as iphone4 screen?
it's really annoying to look at.
Might be a good time to schedule an appointment with your local optometrist.
My screen with text looks great.
haha. every other screen in my life is good.
Maybe I have a bad one. The app icons all look fuzzy too.
That'll be the Pentile matrix, doesn't bother most people.
Unless you have it really bad, then it might be a bad one.
Pentile RGBG matrix... effective resolution is lower than RGB. Comparing it to an iPhone 4 screen with even higher RGB resolution makes it look worse... so I suggest switching to a phone that has an RGB LCD like the MT4G or something if you don't want to deal with the pixelation. Also, the screen being 4" doesn't help... compared to a condensed 3.5" iPhone display.

That's also why I thought 4"+ was too big for 800x480 (S-)AMOLED. I was actually surprised for Samsung keeping that resolution.
Still, at such resolutions, I value vibrant colors more than higher resolution like on the iPhone 4.
Thanks for the info. It seems what's getting me is that images and apps aren't all made for the high res screen. So some look horrible, others don't.
SO I guess the lack of a standard, like iphone, makes not all apps equal.
hmmmmm
The only thing keeping me from getting this phone is the pentile matrix SAMOLED screen
Pretty much everything will be OK for the screen, 800x480 has been in common use for over a year.
You may have a duff one like me. The text on my Galaxy S is very well defined but slightly blurry on my Nexus S with a dodgy screen. Does your screen look a little greeny / yellow when viewed from an angle?
Unless its really bad blurry, its most likely just the pentile sub pixel layout all Samsung amoled screens have, which causes text to look just ever so slightly fuzzy compared to traditional lcd screens with full 3 pixels. It doesn't bother most people, and It's just a trade off we make for having the nice colors from amoled screens for the time being.
Doesn't bother me one bit. But the larger the screen gets at the same resolution, the more noticeable it gets. Next to my nexus one I can definitely notice it more on the 4 inch than the 3.7inch screen.
I have also noticed this "blurry" text, especially small text against a white background, which is almost unreadable. From an angle, the screen also does appear a bit yellowish. This is my first time with a "Galaxy S" phone, so I may just not be used to it... think i have a defective screen? i've been using a Motorola Droid 1 for the past year, fyi...

No I think your screen is just fine. The amoled pentile is particularly blurry compared to the Droid screen which has text that looks razor sharp. So you're just coming from the device that shows this issue most prominently, that's all.
Certainly my Galaxy S with the exact same panel is perfectly readable from many angles.
My Nexus S text is blurry and the screen is yellowish when tilting.

buy the asian/russian version when it comes out. because it will be SLCD.
you will get what you want.
i like the Super Amoled over the SLCD . i like Ratina over Super Amoled. but to each has his own .
So to you SAMOLED > SLCD, but Retina > SAMOLED. You do know that Retina = LCD right?

ofcourse, you understood me wrong. i said the name" retina " because of the pixel density is higher than normal LCDs or SLCDs. but yeah ofcourse i know lol.
Screen Door Effect... WHY GOOGLE/Sammy???
ok, just had a chance to look at the Nexus S... and WTF??? The screen is so pixelated. The screen door effect is horrible. I thought I took a step back in time for a second. The pixelation is soo bad I would never think twice about buying this phone. Why oh why don't these phone makers give the people what they want.
So, Apple comes out with the new retina display, and while it is way too small, it's soo very very very clear. Google's response? This? Come on... WHY? Aren't we suppose to be moving forward? Ok, so it's brighter and uses less power and has a higher refresh rate... WHATS THE POINT IF YOU CANT SEE ANYTHING???? THERE IS NO POINT.
I don't mean to be harsh... I'm not a Nexus hater... I just wish Google would have done a better job for their flagship phone.
Never been happier with my EVO on Cyanogen...

Get it in another country. In many countries it will come with Super Clear LCD, found on the S8530 Wave II. Super Clear LCD is said to have the advantages of Super AMOLED (sunlight visibility, viewing angle), but wheter that's true or not, it's a really nice display. Look it up on the internet, although I have to warn you, you'll lots of people complaining about the screen because the S8500 Wave I had Super AMOLED.
I've seen many phone screens but so far the sharpest crisper phone screen I've seen is the sidekick lx 09, followed by the iphone 4 and the tmobile G2 and the nexus one. The reason for being that the sidekick has 854 x 480 resolution in a 3.2" screen.
The iphone has a 640 x 960 resolution in a 3.5" screen about the same resolution but the sidekick has more pixels per inches because its a smaller screen than the iphone.
Tmobile G2 and the nexus one with a 480 x 800 resolution are the sharpest screens I've seen after the sidekick lx 09 and iphone 4.
What are the sharpest crisper cellphone screens you've seen so far?

Really? The G2 and Nexus one? Yeesh... First would have to be iphone 4 though the screens too tiny for my taste. From there I'd say the Samsung Focus, then the Dell Venue Pro, from there it's all downhill... I don't think android really shows the beauty of a screen properly or I'd put the Galaxy S line somewhere on there... probably along-side the focus.

PPI is no big deal to me especially considering the difference in screen size and the fact that nothing looks sharp on an HTC LCD screen. The lx 09 I guess has a decent screen but for a tiny non-touchscreen screen that doesnt really mean much... iPhone 4 has an awesome display, just too small a phone and too ugly a UI for me...

Super lcd has is the sharpest after retina display on touchscreen phones, the super amoled isn't as sharp as the G2's screen. And to add that the colors on the super amoled look over saturated no natural colors, only thing the super amoled got on the super lcd is the blacks lol the only thing super amoled got better than lcds. I don't understand what yu mean by that htc screens aren't sharp?

The no natural colors argument is an excuse for lack of quality. The vibrancy of AMOLED and SAMOLED looks much more natural than the washed out colors of HTCs LCD screens... If by sharp you mean PPI then I'm sure I could get a phone with a 3 inch screen that owned any of those... However for all visual purposes AMOLED looks best with SAMOLED in a close second (SAMOLED puts a blue hue on white colors that I dislike) then in distant last is LCD screens. I'm watching the same show same episode of smallville on an HD7, a Dell Venue Pro, and a Samsung Focus right now. The Focus and the DVP are right on par with each other, the HD7 is trailing... I mean the Focus has 223 PPI which unless you're holding the phone less than a foot from your face is hardly discernible and the DVP is at 228, again barely discernible. There really isnt much difference between that and the 256 of the g2 and with that you sacrifice screen size and get caught on an LCD screen... no thanks.
I love how this is just a hate thread. I'd prefer to read something other than this hateful garbage. WAHH WAHH HTC PHONZ SUKS KAWS I GOTZ AMOLED. Perhaps the iPhone and G2 ARE sharper quality physically, but the human eye can barely distinguish. My screen looks beautiful whether you agree or not.

I was talking about the super amoled which you agree sucks with white colors, and not only that but it has a greenish tinge on yellows that looks very unatural, I haven't seen an amoled screen, I only seen OLED and SAMOLED, my cousin got the epic and super LCD has way more natural colors, look at the youtube video comparison and you'll see what I'm talking about and remember to YOU it looks better than SLCD not to me, it all depends on what looks better to you I personally don't think colors are washed out like you claim on SLCDs, however I think colors are over saturated on SAMOLED. Thank god htc can't implement SAMOLED displays on htc devices hopefully they'll keep SLCD since samsung is the only one that makes SAMOLED

What phone do you have? And which screen you like better SAMOLED or SLCD?, and listen some might think Samoled has better colors but who cares IMO, and probably yours too, SAMOLED is does not have better colors, we all have different taste and opinions, and SLCD out of all I've seen is the best, its natural in colors, reds doesn't look like. Orange or like they're bleeding and yellows don't look greenish, it is very sharp and has great brightness, if it only had the blacks the SAMOLED has it would be the perfect screen, but still I could give two cents for how black are the blacks.

I agree that it looks pretty nice... I personally prefer AMOLED over the alternatives Super LCD included. SAMOLED is a little out there but I'll take that over devices with the basic LCD screen that most devices are still harboring. I mean all in all it's not a huge difference between most devices but AMOLED and things like that... they just appeal more to me. The colors even though they can be almost cartoony are still visually enthralling. AMOLED is good, Super LCD would take second, from there I'd say amoled, oled, then LCD. Pixel density is hardly visible to the naked eye so as long as it's not just terrible it's all about the type of screen... this is all just my opinion though.

Agreed, I think my distaste for the washed out colors is because a heavy portion of Windows Phone 7 is black and blacks are not too good on LCD screens as you mentioned earlier.
I like Super Amoled actually, nevertheless, I will wait for WP 7 phones from Nokia.
They will throw the Clear Black Displays in them, I reckon. And the clear black displays were proven to be the best in a GSM Arena review.
BTW, I don't like Nokia, but I always go for the best.
..................
Managed to film the difference between the blacks of the X and S.
both phones were on full brightness.
I can't see much of a difference on my monitor but can definitely see a difference when viewing the video on both the X and S phones.
http://www.youtube.com/watch?v=YtpEY5L2QeY
No **** man... the HOX have an LCD panel... that means is lit by LED's whereas the HOS has an SAMOLED panel... ie NO backlights.
What's new?
And ofcourse my HOS has arrived and I like it alot. But I miss the design of the HTC Desire... I don't mind the screen size of the HOS but the thinness of it will take a while to get used too I think.
Comparing black test between One S and One X is no more different than comparing amoled with lcd. If you like the contrast, the amoled one s is a good choice. If you prefer color accuracy, the One X with its true RGB ips lcd is the best out there, together with the LG something.

IPS (iphone and one x) and amoled (lumia)
http://www.youtube.com/watch?v=MZjfe2_zUo4
so totally going for color accuracy
So currently these 3 types of display techs(mainly their variants like Super AMOLED, Super Clear LCD, Super IPS LCD, LED Backlit LCD,IPS TFT etc) are the main kinds of display technologies which can be seen on the latest phones.
I have a few doubts regarding this topic.
1- Which technology gives the best color reproduction?
I know AMOLED sucks at this field.What about Super IPS n LED Backlit LCDs n TFTs?
2-Which one has the best viewing angle?
3-What is all this pentile matrix stuff about AMOLED Displays?
4-Longevity,which one lasts long without noticeable degradation?
5-One technologies main advantages/disadvantages over another

1 amoled has very good contrast. but pixel density also important. Phone could have anyone of these displays and have varying dpi
2 IPS has the best viewing angle
3 i heard of that I've have to google it.
4. Longevity has too many variables. depends on use quality and always random dud phones so idk.
5. depends on what you want it for reading vs watching video the size of the screen quality of a product. you can get knockoff iphone with rentina like display doesn't mean cheap phone will last longer then a lessor display. It's more of a personal choice than an overall one better than another.
1. Depends if you're looking for real life looking colors or bright, vibrant colors. Out of the box AMOLED is the latter, while all LCD's are the former. However, all these screens can be adjusted (Android phones anyways), so it's not such a huge issue.
2. IPS LCD has the best viewing angle, but AMOLED is so close behind it's not a deal breaker. All other LCD's would be behind them, but the amount of which depends on the quality of the panel. iPod Touch viewing angle is terrible, while Xperia Play's is amazing for an LCD.
3. Pentile is just a different sub pixel arrangment. It can apply to LCD or AMOLED, it's just seen more on AMOLED's because it makes those displays last longer. Pentile screens don't look quite as crisp as RGB layout screens, but it's harder to notice with the 720p displays out there now.
4. Traditionally AMOLED doesn't last as long as LCD, but it seems to be panel specific. Some AMOLED panels can last really long. All in all you shouldn't see issues within a 3 year phone contract with either.
5. Totally personal preference. I like AMOLED's myself, mainly for the infinite black levels, vibrant colors, and very good viewing angles. Some people like LCD's because the colors out of the box are more natural. Also some like how there are 720p RGB layout LCD's on phones. AMOLED hasn't been able to do this yet, it has to resort to pentile for those resolutions. Then again, it's hard to notice at ~320 PPI

Personally i seem to prefer SLCD over SAMOLED, the whites are bluish and there's a weird hue in all colors except black in amoled, not sure why but the blacks are true blacks which is not the case in lcd where all colors are perfect except black is kind of grayish because of the back light.

My AMOLED colors were slightly off when I got my phone (a little on the warm side). With a quick color tweak the colors look amazing now, along with the true blacks.

Super Amoled Plus and super LCD are the higher end panels and bring out the best of each technology. However nothing beats a good ips panel in my books. The colors are flawless, and the viewing angles impeccable. That is all I need.

AMOLEDs provide true black because in this technology, each pixels produce its own light(unlike LCDs,in which a single lightsource illuminates the entire screen). And when black is needed to be produced,that individual pixel is completely shut down,thus zero light is emitted.Hence true black.

Technically IPS is a really good TFT panel. Like how a maybach and a c200 are both Mercedes. IPS being the maybach ofcourse.
And technically an LCD is also tft. But then it starts getting confusing if you go down that road.

amoled is much more colourful than the others.
A I-Phone 4 looks really pale beside a Galaxy S or a Galaxy S2.
Amoled has limited life-time and looses brightness.
The power consumption is dependent extremly on the brightness of the colour.

Power consumption is EXACTLY what interests me most about this. I remember reading a couple of years ago that Sony Walkmans using OLEDs offered vibrant colours while using far less power than LCDs. The trouble is I'm having trouble finding more information on this now that I'm looking at OLEDs in smartphones. Is this true, does OLED use less power, does it not use a backlight like LCD?
I'm dying to know because I bought a cool phone a few months ago, but hadn't learned about battery usage/capacity and now I HATE the phone for it. I'm looking at the OLEDs e.g. on the Motorola RAZRs (with 2000 mAh batteries) and I'm curious about them.
UPDATE: I just found a simple document composed from companies and organisations involved in OLED production which, they say is designed to eradicte myths on this. You can see the document here, and on power consumption, my brief understanding is this:
LCD: uses maximum power to display any image
OLED: uses minimal power on darker images, maximum power on brighter/whiter/colourful images - white/very bright images use more power than LCDs
This leads me to think that switching to OLED can only result in at least some benefit in battery life, no? I think most of us on Android are conscious of the use of black and white in the UI, wallpapers etc. so something like this would help. Is it a significant benefit? A backlight on a TV plugged into the wall is fine, on a smartphone I can see why it's a battery-killer. I note the caveat about OLEDs using more power for white and very bright images, but the way I see it, unless you're using a white wallpaper, this isn't an issue. I speculate a power saving when all is accounted for.

So, if a TFT display is considered not quite as good as an AMOLED or an SLDC…how could a difference be noticed between the Xperia Z’s TFT display, the SGS4’s AMOLED and the HTC Butterfly’s SLDC3 – all 5 inches, all 1920x1080? Battery life/colour reproduction/daylight visibility?
Thanks for the input.
decision
I'm sorry for breakin' in this late, but... I hope to help in the future decisions.
We're mixing some things here:
LCD is a technology. AMOLED is another technology.
TFT is a sub technology that must be applied under one of the mentioned before.
TFT is an array used to feed large displays (a mobile phone is already a large display).
Since phone displays are "large" either LCD or AMOLED need an active controller to maintain brightness in each pixel.
This is A BIG difference between OLED (PMOLED) and AMOLED.
As SharpnShiny mentioned mp3 players/walkmans (small displays) can use OLED which use much lesser power than AMOLED.
In OLED/AMOLED displays each pixel produces it's own light, which can be a good power saving if most of the image is black or dark, because, in black the pixel just doesn't light up.
In LCD there's permanently (monitor ON) a "backlight". Even if the image is black! What the display does is block the backlight when it needs black.
About power consumption in either cases... I don't think there's a really noticeable difference because it depends a lot on the usage!
UPDATE: Sometimes the best way to save battery is to tweak several settings (including the Kernel) as the display brightness levels and thresholds.

In OLED/AMOLED displays each pixel produces it's own light, which can be a good power saving if most of the image is black or dark, because, in black the pixel just doesn't light up.
In LCD there's permanently (monitor ON) a "backlight". Even if the image is black! What the display does is block the backlight when it needs black.
About power consumption in either cases... I don't think there's a really noticeable difference because it depends a lot on the usage!
UPDATE: Sometimes the best way to save battery is to tweak several settings (including the Kernel) as the display brightness levels and thresholds.

Thanks! That's what I intend to say. It seems many people misunderstanding about TFT.
TFT is not a panel technology in comparison with TN, MVA, IPS, PLS, AVS, AMOLED,....
1- Which technology gives the best color reproduction?
I know AMOLED sucks at this field.What about Super IPS n LED Backlit LCDs n TFTs?

In other hand, Led-backlit is a similar case, it is a type of backlight, cause the LCD need the illumination. And there are 2 kind of LED, Edge and full-array. In mobile, almost is edge-led because of low cost and thickness. Full-array Led backlit only appear in several high-end TV models. The older tech is CCFL, which consumes more power
It means that a new LCD display which uses IPS panel also include a TFT layer and an edgeLed-backlit.
Sorry if any typo mistake. My bad English
Does anyone here know much about SAMOLED? I read in a phone review that it's more a marketing term than actual performance difference over AMOLED, but I'd prefer to double check that. For anyone who hasn't seen that term, the S is for Super (don't laugh yet!). I think the Motorola RAZR i and the Samsung Galaxy S III Mini are using SAMOLEDs.
I've been comparing my new and old phone screens when considering this thread. I have to say I prefer the TFT LCD screen more than anything. Even with a lower resolution, the images (video and static) is beautiful to me. My RAZR i has a higher resolution but a pentile matrix SAMOLED. It reminds me of phones 5 years ago, the matrix gives the impression of cheap pixel displays in my opinion - but I keep reading it's amongst the most battery-saving screens in the mainstream smartphone market and for that I am greatful.
I get noticeable battery drain difference by turning down the brightness on my AMOLED screen.
Decreased brightness also extends the life of the display.

Yes. SAMOLED is the Super AMOLED from Samsung.
I wouldn't dare to say that it's just a marketing stuff... Because it's a little about "sub-pixels" and their layout. I would say thay the AMOLED technology is there with Samsung's engineering so that picture could get better.

That's what I meant in my last post, under the UPDATE statement. Also try to tweak your phone's clock (if you haven't done it yet).
Mine (a poor 600MHz ZTE Blade) is working from 245MHz to about 650MHz depending on the load (from underclock to overclock).
Amoled or OLED screens are overrated, Poco-f1 screen doesn't lag behind in any circumstances.:cool
Yeah, but it drains more power even with an all black setup.

Lo. I wonder if you have ever used a Samsung device with sAMOLED display? Just place both a sAMOLED and a LCD display side by side and see the difference.

Previous phone was Galaxy S8, I don't find much of the experience difference.
IPS LCD and AMOLED displays has advantages and disadvantages
IPS LCD has that AMOLED doesn't have:
-Sharpness and Clarity is good
-Natural Colors (AMOLED is little saturated on Colors)
-Can recover to accidental burns or screen burns (AMOLED cannot recover on screen burns thus leaving white marks)
-Longer pixel life (AMOLED's pixel quality degrades over time)
AMOLED has that IPS LCD doesn't have:
-Improve battery life as turning off pixels without backlight (Good for Dark Themed apps, videos, photos)
-Brightness and Contrast is good
-Good Viewing angles
-Always-on Display (IPS LCD cannot support this due that it uses backlight rather than turning off black pixels thus increasing power consumption)
Verdict:
No clear winner. It is the preference of both users and the manufacturer on what type of display they want to use. This is why Xiaomi uses IPS LCD Displays because it is cheaper than AMOLED ones. The target is being a budget flagship-tier phone thus achieving it.

Yeah best done with a gray picture so you can see the burn in on the oled. After some burned oled I only buy IPS screens.
I can't understand the "true black" hype as there is no such thing in real life and as the brain even can interpret white as black if the contrast is right.
As long as OLED tends to burn in, it's a no-go for me.

Three reasons why Xiaomi should go the OLED route :
True black :
Here's an example of true black :
On you Poco, go to full screen settings and turn off the notch. Now to two top corners are rounded as the bottom ones. Now go to a dark room, as if you were using your phone at night. Well you still see the top corners of your phone's screen on. Of course that color is black, but it's awful. (In a dark room you see it better, but I see it in the sun as well).
Always-On-Display or AOD :
You can't have AOD on an ips panel. End of the story.
Brightness :
Outside in full daylight, I constantly have to block sunlight off the screen and put it right up to my face to see what's on it. OLED is way brighter.
Bonus :
Dark mode is here in the MIUI beta and coming to everyone later. MIUI 11 will have it out of the box. This means phones with OLED screens will have a great battery advantage over ips.
Also - OLED and AMOLED tend to use very low PWM which may give you a headache/migraine.
For instance - Xiaomi Mi 8 with AMOLED panel has backlight that flickers at 100 Hz, Samsung S9+ has AMOLED panel with backlight that flickers at 215.5 Hz while Pocophone has a backlight that flickers at 2315 Hz (source - notebookcheck reviews)

They have pros and cons, both of them. While sAMOLED has better contrast, black colour, and often better viewing angles, IPS has most of the time better colour accuracy and it's better to look at while exposed to direct sunlight. I mean, you use the one which suits you the best. Unfortunately, Xiaomi uses probably some cheat IPS panels, so they look worse compared to some higher end phone with IPS panels.
True black is just an excuse ??
And amoled panels aren't bad or anything. They are just over rated and people say. Amoled- amoled l. Look it's not that a big of a deal.
And battery consumption difference is just minor
Like 3 or 4% through dark mode in amoleds too
So what's the hype
I just said Poco-f1 LCD panel is just as good as OLED
If not it's only a difference of 19-20
Nothing more
Ill always prefer lcd. When i bought the phone i had to keep it on over night for data transfer via wifi as i had no pc , to keep the wifi transfer app alive i had to keep screen timeout to never, on morning i noticed lcd retention all over the screen ?(similar to amoled burn in but not permanent), had it been an amoled surely my screen would have to be replaced day 2 of buying a new phone. I had to use the phone screen a lot but the Lcd retention went away completely after around 8 hrs:victory:, so no amoled ever unless they fix burn in!
lol this thread is like a circlejerk. my poco f1 has crappier display than my a2. it has the lowest quality lcd possible. this comes from someone who has used over 37 android smartphones throughout this decade with many being top tier flagships.
But poco F1 has a comparatively dim display even for an LCD. Under heavy sunlight it becomes difficult to see the display. On S10 for example you can clearly see it in any condition. That is why they bumped up the brightness in the poco X2
